Use instances with `canRunChildTask: true` and no `constraints`. Its model list is short: use `search` for omitted families or models named by the defaults or current file. Never write a disabled instance or an unadvertised model. +- Load. Read ``. If missing, native `~/.claude/rules/pstack-models.md` or `~/.codex/pstack-models.md` may seed a proposal, but validate each choice against the T3 catalog. +- Grammar. Write `role: value`. A value is `inherit-parent`, `auto`, or comma-separated entries, each `/ = ...`. Split the instance and model at the first `/`; model ids may contain more slashes. `true` and `false` are booleans. `#` lines are comments; preserve the `# budget:` line. Panel alias entries still count as seats. +- Defaults. Use the 17 role labels and values in step 5. Match `claude-*` to an enabled `claudeAgent` instance, `gpt-*` to `codex`, `grok-*` to `grok`, and `composer-*` or `cursor-grok-*` to `cursor`, offering the model. A missing family needs a choice; propose an available different family for mixed panels. Do not invent a model. +- Effort. Find the select option whose advertised `values` contain at least two of `low`, `medium`, `high`, `xhigh`, `max`; use its advertised `id`. This also covers Pi's `thinking` and OpenCode's `variant`. The ladder is `max` > `xhigh` > `high` > `medium` > `low`. +- Budget. Keep step 3's four labels. `unlimited`, `large`, `medium`, and `small` target `max`, `xhigh`, `high`, and `medium`. Set each real entry, including panel entries, to that value or the highest advertised ladder value below it; with none, mark it as needing a choice. Never select off-ladder values such as `ultra`, `ultrathink`, `none`, or `minimal` under a budget. Aliases, models without an effort option, and explicitly chosen off-ladder settings stay unchanged. +- Speed. A `-fast` default maps to `fastMode=true`, `serviceTier=priority`, or the advertised `serviceTier=fast` only when supported. Otherwise drop it and say so. A budget change leaves speed unchanged. +- Show and confirm. Offer detected models plus `inherit-parent` and `auto`. Show all 17 roles, panel sizes, and any unavailable instances. Confirm choices as the skill directs. +- Validate. Every concrete instance, model, option id, and value must appear in this run's catalog. Aliases always pass. +- Write. Write `` with no frontmatter: comment lines, `# budget:`, then one line per role. Write only options the user chose; T3 completes omitted options from the provider's current defaults. Overwrite the whole file. Never put role lines in `AGENTS.md`, `CLAUDE.md`, or a harness rule folder. +- Confirm. Say the file applies to the next pstack run on this environment. Another environment needs its own setup because its provider instances differ. + +## Paths + +| Cursor | T3 Code | +| --- | --- | +| `.cursor/skills/`, `~/.cursor/skills/` | Project skills go in `.agents/skills/`.

Webhooks: `schedule_task` with `{"type":"webhook"}`, then report its `webhookUrl`; with none, skip with the line, naming T3 Connect remote access. The run reads the request only through `{{body.path}}` placeholders in its prompt, which replace a `` payload. `SendToUser` secrets: `request_secret`, then pass the one-use `secretRef`, such as `signature.secretRef`. `update_state`: skip with the line; a schedule keeps no state between runs. | +| `/loop ` | `schedule_task` with `{"type":"interval","everyMs":...}` and the brief preamble plus the tick as `prompt`. Report the cadence and `nextRunAt`. Delete it with `delete_scheduled_task`, passing its `scheduledTaskId`, once the loop's stop condition holds. | +| `/loop` in dynamic mode, or a watcher subagent that wakes you | Wake on the event itself: `watch_pull_request` for CI, reviews, and conflicts, and child completions for delegated work. A delegated child returns its PR state to its parent; only the parent watches. Add one long `schedule_task` heartbeat only where the step asks for a fallback. End your turn instead of sleeping. | +| `scripts/watch-pr/watch-pr` polling in `drive` or `background` | If you are a child, return the PR URL, head SHA, and pending checks to your parent. Otherwise `link_pull_request`, then `watch_pull_request` with `mode: "checks"`, or `"review"` to also wake on comments, then end your turn. On each wake, get the verdict from one `watch-pr --status-only` run or the forge's PR view. Re-arm after each push wave. A wake is not merge authorization: keep the step's head-SHA and merge rules. `unwatch_pull_request` when done. | +| Bugbot | Bugbot comments on a GitHub PR are ordinary review threads, so triage them with the forge command the step gives. `watch_pull_request` with `mode: "review"` wakes you on new ones. Skip a step that starts, waits for, or configures Bugbot when the PR has no Bugbot check or comment. | +| Cursor cloud agents | `environment: "cloud"` maps to a worktree, as in Subagent fields. Report a cloud agent's dashboard status with `task_status` and a `[title](t3-thread://v1/)` link. A worktree is still on this environment. Skip a step that requires the cloud agent's own machine; the resolved targets do not select a remote environment. | +| A built-in PR tool | Use the forge command the step gives, such as `gh pr create`, then `link_pull_request` with the PR URL. That is not a skip, so write no line. | +| A Custom Mode (Option+Enter, Use as Mode) | Skip with the line. T3 Code has no sticky skill mode, so start each task with `$pstack:poteto-mode`. | +| Plan Mode | T3 Code's Plan interaction mode. Ask the user to switch the composer to Plan; for a child, pass `interactionMode: "plan"`. | +| Cursor's built-in `create-skill` | Write the skill folder yourself, in the project skill folder from Paths. | +| `cursor-team-kit` skills: `deslop`, `control-ui`, `control-cli` | Use one if your harness lists it. Otherwise `control-ui` is the `preview_*` tools for web UI and the `device_*` tools for a phone or simulator, `control-cli` is the shell, and `deslop` is a skip with the line. | + +## Harnesses + +All harnesses use `$pstack:` composer chips and the `t3-code` tools; none installs pstack. + +| Driver | Decision | Notes | +| --- | --- | --- | +| `claudeAgent` | Supported | A native pstack plugin may also be loaded.

The one verdict may ask one focused question and use the `other` marker. + +## 5. Apply configured routing + +Read the optional routing map from `routing.map_path`. + +- Match on confirmed product area, code path, or error signature. +- A visible symptom alone is not enough when cause tracing points elsewhere. +- If no route matches, say the owner is unclear.

Do not reopen, relabel, or reassign it unless the config says to. + +For a possible match, link it in the verdict as uncertain and create nothing. + +A long-closed issue is a regression lead, not automatically a live duplicate. + +## 8. Decide whether to create + +Create only when all of these are true: + +1. The classification is bug or performance. +2. The behavior is clearly broken. +3. The issue is still live or not known to be fixed. +4. Dedupe found no confident or plausible live match. +5. The source parent and permalink passed preflight. +6. The tracker target fields resolved. +7. The adapter can compensate if the verdict post fails. + +Never create for a feature request, question, feedback item, reroute, possible duplicate, confident duplicate, or already-fixed issue. + +The new issue must be self-contained: + +- Plain title that names the area and symptom +- Reporter quote +- Expected and observed behavior +- Version and environment, or `unknown` +- Trigger and frequency +- Source thread permalink +- Short cause-tracing findings with hypotheses labeled as hypotheses +- Inline screenshot or representative video frame when supported +- Links to remaining artifacts +- Configured intake status and labels + +Do not put a guessed root cause in the title. + +## 9.

The same goes for a list of skills, covered in the pitfall below. +- **Your theory of the cause, at first.** A stated guess narrows the search to wherever you pointed. Let the agent restate the problem before you share your hunch. + +For a noisy report, such as a long thread or a vague bug, make the restatement the first step: + +```text +/poteto-mode read this thread. restate the underlying issue in your own words, in plain english. don't change any code yet. +``` + +A misreading shows up in the restatement, before any code exists.

Each bug TLC finds is a numbered path in the reader's words, and each state is marked works, still wrong, or fixed by your open PR. Before the hand-off, the agent reproduces each bug path in the real code, so a modeling error doesn't reach the reader as a bug. + +It also runs the other way. Sketch the behavior as a chart, agree on it with the reader, and the skill writes a TLA+ skeleton from it. TLC checks the agreed chart's rules before any code exists. As guards from the real code go into the spec, each place the code departs from the chart shows up as a difference for the reader to decide. + +When the code already has a TLA+ spec, the skill can audit the code against it. The agent models what the code does and checks that model next to the unchanged spec.

State the goal and constraints. Name a skill only to override a default. +- **A vague finish condition.** "make it better" gives `/loop` nothing to check. Give a command or artifact that can pass or fail. +- **Leading with your theory of the cause.** The agent searches wherever you pointed. Ask it to restate the problem first, then share your hunch. +- **Taking the first design.** One attempt locks in the first shape the model thought of. Ask for prototypes or `/architect` and pick from evidence. +- **Polishing an abstract plan.** Adversarial review of a plan with no code behind it invents risks that will never happen. Settle the open questions with prototypes, then review what got built. +- **Parallel agents in one worktree.** They overwrite each other, and nobody can tell which agent changed what. Run them as cloud agents, or say "own worktree per attempt". +- **Looping before you trust the loop.** A loop that can't verify its own work only makes unchecked work faster. Get the verification skill working first. +- **Trusting an unvetted number.** A warm cache or a skipped code path can fake a speedup. Run `/benchmark-checklist` before the number goes anywhere. +- **Correcting the same mistake by hand.** A correction in chat helps one run. `/correct` fixes the repo so no later run repeats it. +- **Using `/arena` for coverage.** `/arena` repeats one design or code brief, then picks a base and grafts the best parts. `/swarm` partitions slices or declared race arms and aggregates one report. +- **Accepting every review comment.** Bots and humans both file real catches and noise in one list. `/interrogate` sorts findings into act-on and dismissed buckets with reasons, and you can override either way. +- **Treating `auto` as a model slug.** `auto` and `inherit-parent` mean "omit the model field so the subagent inherits the parent chat model." [Setup](./01-setup.md) covers the roles. +- **Reporting success off a green build.** A build proves it compiles.

If the machine is busy, find out what is running. If you cannot stop it, interleave the sides so both see the same noise, and say so in the report. + +## The questions + +1. **Why not double?** Name the limiter. Profile in a run you do not report, because profilers and tracers slow the work down. Use CPU per process (`top`, `pidstat`), a runtime profiler (`node --cpu-prof`, `py-spy`, `perf`), I/O wait, and syscall counts (`strace -c` on Linux), then map the hot spot to source. Watch the load generator too: if it saturates first, you measured the load generator. If a change did not move the number, the limiter explains why, so find it before you call the change useless. +2. **Was it tuned?** Run every side the way production runs it: release builds, production flags and env, batching and transaction settings, connection pools, caches as warm or cold as production sees them, and the same versions and data. If one side runs on defaults, you compared configurations, not implementations. A limiter that is a setting (a commit per row, a debug build, a missing index) means that side is untuned. Tune it and measure again before you pick a winner. If you cannot tune it, do not pick a winner from that run. When the user is choosing what to adopt, narrowing the claim to the code as it ships today does not fix this, because they adopt the option, not today's settings. +3. **Did it break limits?** Do the arithmetic. Compare bytes per second with disk and network bandwidth, operations per second times cost per operation with your cores, and the time saved with the time the changed piece took. Removing a piece that takes 10% of the run can make the run at most about 11% faster. A result past a limit measured something other than the work, such as a cache, a no-op, or a bug. +4. **Did it error?** Count failures and non-success responses, and check that outputs are correct, not just present. Rejections are often fast, and timeouts and retries are slow. If the script does not count errors, add the count. +5. **Does it reproduce?** Run each side at least 5 times, alternating (A, B, A, B, and so on) so warmup, lazy initialization, caches, and drift favor neither. Report the median and range. A gap smaller than the run-to-run variation is no measurable difference. When the call is close, use a rank-sum test or the harness's own statistics. +6. **Does it matter?** Next to any micro result, measure the end-to-end path a user waits on, with realistic data sizes and concurrency, and report the micro result as a share of the whole. A helper that takes 1% of a request can make the request at most 1% faster, however fast the helper gets. +7. **Did it even happen?** Confirm the work ran inside the timed region: the request reached the server, the rows were written, the bytes were read, and the code used the result. Lazy code (generators nobody iterates, promises nobody awaits, results the JIT can discard) and timeouts produce numbers for work that never happened. + +## Report + +- Lead with the verdict: faster, slower, no measurable difference, or inconclusive. +- Give the number with its unit, the run count, the range, and the limiter. For example, "p50 41 ms → 33 ms, median of 7 runs per side, range 32 to 35 ms after, bound by JSON parsing on one core." +- Call the verdict inconclusive when you claim a difference but cannot name the limiter, when a side ran untuned, or when you could not check questions 4 and 7. Name the gap. +- Keep a PR body to one primary number, per the **Opening a PR** playbook. Put the runs, range, and limiter evidence in a linked artifact or notes file. + +## Other perf material + +- Vet the **Perf issue** playbook's baseline before the playbook plans from it, and every number after that. +- Vet the **Hillclimb** playbook's harness before it is frozen.

What the verification treats as one indivisible step is one indivisible step in the code. Names come from this repo. +- **Able to fail.** A check that you have never seen fail proves nothing. Show each property failing on a broken variant of the code it guards, such as a removed check or a reordered step. +- **Findings stay findings.** When the current code breaks the property, report it with the counterexample in the code's terms. Do not weaken the property or the model until it passes, and do not change product code unless the user asks. +- **Honest about scope.** Say what is verified, under which bounds and assumptions, and what is left out. A pass covers the model or the bound, not the whole system. +- **Readable without the tool.** State the property and the harm in one plain sentence each. Tell a counterexample as a short sequence of steps in the code's words. +- **Cheap to rerun.** One command, a reproducible tool version, and a run short enough that the next agent will use it on every relevant change. +- **Kept in step with the code.** Record which files and functions each check covers, and the commit at which you last confirmed that the verification describes them. When the covered code changes after that commit, the next agent can see that the verification needs another look. + +## Generate the verify skill + +Write a project-local skill with frontmatter that names the area and says when to use it. Without frontmatter, the skill never registers. From the skill alone, the next agent must be able to tell whether a change touches the verified code, run the check, tell a real bug from a modeling error, and update the verification when a change is intended. Put the coverage record and the sync commit in the skill, and tell the next agent to move the sync commit forward only after it confirms that the verification describes the code at the new commit. Use this repo's real commands, paths, and nouns, and leave no placeholders. + +If the check is a TLA+ model, tell the next agent to read every result with the pstack [`/statechart`](../statechart/SKILL.md) skill. It shows each invariant violation the checker finds as its shortest path in plain words, and which of those violations a change fixes. When the check passes, `/statechart` draws a chart of how the system moves between states. Refer to `/statechart` by name. Its commands, options, and file paths change between releases and machines, so copy none of them into the generated skill or its scripts. + +## Prove it before you hand off + +Follow the generated skill once, as the next agent would, on a scratch change that breaks the property in the real code. It must catch the break. Then drop the scratch change and confirm that the check is back where it started: passing, or failing only on the findings you will report. A verify skill that was never run is a draft. If the skill misses the break or a step does not run, fix the skill or the verification, not the scratch change. + +## Hand off + +Tell the user what you verified, which tool you used and why, the bounds, what the check found in plain words, how to run it, and what it does not cover. Suggest a second target only if you found a close one. Point the user at `/maintain-formal-verification-skill` for bringing the verification back in line after changes that did not recheck it. diff --git a/packages/pstack/upstream/skills/create-verification-skill/SKILL.md b/packages/pstack/upstream/skills/create-verification-skill/SKILL.md new file mode 100644 index 0000000000000..140d033a001e8 --- /dev/null +++ b/packages/pstack/upstream/skills/create-verification-skill/SKILL.md @@ -0,0 +1,44 @@ +--- +name: create-verification-skill +description: "Generate a project-local verification skill that drives your app the way a user does — any language, framework, or platform.

A web UI, a CLI/TUI, a desktop app, an API, a mobile app, a library? A repo can have several; pick the primary one and note the rest. +- **Run:** how does the app start locally? Prefer the repo's own documented dev command (package scripts, Makefile, README quickstart). Note ports, env vars, seed data, auth. +- **Drive:** how can an agent interact with it programmatically? Existing harnesses first — Playwright/Cypress specs, expect scripts, PTY helpers, curl-able endpoints, a debug port. Only then pick a generic recipe: browser/CDP for web and Electron, a tmux/PTY harness for CLI/TUI, plain HTTP for services. +- **Observe:** what evidence can be captured? Screenshots, terminal transcripts, response bodies, logs, exit codes, DB state. +- **Isolate:** can two instances run side by side (ports, data dirs, profiles)? If not, say so in the generated skill: refusing to double-drive a shared instance beats corrupting the user's session. + +If the checkout doesn't build or start as-is, fix that first (or report it precisely) before generating; a skill written against a broken base teaches wrong steps.

Launch must reach a usable state from an empty data dir, including any migrations and seed data. Ready means usable, not just that a process answers. A database health check can pass while its init scripts are still running. Include teardown. For a short-lived CLI or TUI there is no server to keep alive: launch means build the binary (or install deps) once, then start each drive in its own isolated PTY or tmux session. +- **Doctor:** one read-only check that answers "is this instance worth driving?" — process up, right version/build, port owned by us, auth valid. An agent runs this first whenever anything looks off. +- **Drive:** the harness recipe with real selectors/commands from this repo, not examples. Prefer stable handles (ARIA labels, data attributes, prompt strings, route paths) over coordinates and tab order. +- **Evidence:** what to capture for a proof and where it goes. State the proof standards: exercise the real user path, not internal setters or test-only endpoints; capture the action and the resulting state, not just the final screen; verify side effects (files written, rows inserted, messages sent) alongside what's visible; mocks only where a production boundary already isolates the external system. When the safe path is a dry-run or test mode, verify what it actually skips by observing (files, network, git refs) rather than trusting its name: some dry-runs still touch the network or open a browser. +- **Cleanup:** how to tear down instances the run created. Never kill by process name; kill what you started. Cleanup removes instances and scratch state, never the evidence: proof artifacts survive the teardown, in a location the skill names. +- **Helpers:** any script the skill ships is executable and its invocation is shown in the skill body. A helper the reader has to reverse-engineer is not a helper. + +## 3.

Follow the shape in [`references/feature-map-example/`](references/feature-map-example/), with a README index and one file per feature. Each file answers, from the user's point of view: what the feature is, how to reach it, how to drive it with the harness, and what observable end state proves it works. The four H2s are `Sub-features`, `How to get to it (user POV)`, `Driving it with `, and `Gotchas`. If the seed data lacks a precondition that a journey needs, the journey reports a failure and the reason goes in that feature's `Gotchas`. Never weaken the journey to make it pass. The map is the repo's maintained verification source; a proof that drives one convenient entry point is incomplete when the map lists others. + +## 4.

Fix what fails, and run the generated cleanup after every failed iteration too, so broken attempts don't strand processes and ports.

Say exactly why. + +A check can be both updated and bug: the update makes the verification describe the code again, and then the property fails on it. + +## Edit scope + +Edit only the verification: models, harnesses, property files, and the verify skill itself. Never edit product code during a run, unless the user asks you to. When a property fails on the current code, do not weaken the property or the model to make it pass. Report the failure. + +## Pass + +1. **Find the checks.** A verify skill has no fixed name, so find it by what it does: a project skill that runs a model checker, a prover, or another verifier against named code. Read each one you find, or the one the user named. For each check, collect the property, the code it covers, the bounds and assumptions, the command that runs it, and the commit where it was last confirmed to describe the code. If no verify skill exists, stop and point at `/create-formal-verification-skill`. If the skill does not record a sync commit, use the last commit that changed the verification files, and say that you did. + +2. **Run it as it is.** Run each check once before you change anything, and record the result. A pass here does not tell you that the code is correct. It tells you that the old description still holds. A failure here can be drift or a bug. Do not decide which until step 5. + +3. **Read every change to covered code.** Diff the covered files from the sync commit to the current commit, and read each commit message. Also look for code that moved: a covered function that is renamed, split, or moved to another file is still covered code. Also look for new code that touches the state that a check guards, such as a new function that writes the same fields. For each change, decide which of these it is: + - **No effect.** The change does not alter anything the verification describes, such as formatting, comments, or code paths that the verification does not cover. Check this against the model or harness, not against the commit message. + - **The verification no longer describes the code.** A step that was one indivisible action is now two, a branch was added or removed, a check moved, a new path reaches the guarded state, or a value now has a different range. The model or harness must change. + - **The promise changed on purpose.** The change alters what the code promises, and evidence in the change says that this is intended: the doc comment, the tests, the changelog, or the commit message. The property must change, and you must cite that evidence. + - **The promise may be broken.** The code changed, and no evidence says that the promise changed. Treat a failure that follows as a bug candidate. + +4. **Update from the code, not from the result.** Change the model or harness so that each changed part again points to code that a reviewer can open, and keep one indivisible step in the code as one step in the verification. Write the update from the code before you rerun, and do not shape it by what makes the check pass. Change a property only for a promise that changed on purpose. Write down the old wording, the new wording, and the evidence. Keep the bounds unless the change makes them wrong. If you must reduce a bound, say so in the report. + +5. **Rerun and judge each result.** + - **Pass:** the check can now pass on a description that has lost the ability to fail. Break the new code the way the property guards against, such as removing a new check or reordering a new step, and confirm that the check catches it. Then drop the break. + - **Fail:** replay the counterexample against the real code, step by step. If a step cannot happen in the code, the verification is wrong. Fix the verification, and say what was wrong. If every step can happen, it is a bug. Name the commit that introduced it, tell the counterexample as a sequence of steps in the code's own words, and state the harm in one sentence. If a cheap test or reproduction against the real code shows the bug, add it to the report as evidence. Do not commit it to the product code. + +6. **Update the verify skill.** Update the code that each check covers, the commands, the bounds, the assumptions, and the sync commit. Set the sync commit to the commit that you checked. Do not move the sync commit for a blocked check, and say so in the report.

Children never drive the app and never edit files.

Sweep recent churn for user-facing surfaces missing from the map — require a concrete source path before calling one missing. + +4. **Live pass.** Required even when source looks clean. The coordinator owns all driving; follow the verification skill's own launch model — one long-lived instance driven serially for servers and UIs, or a fresh isolated session per drive for short-lived CLIs (the skill's Launch section decides, not this one). Exercise every feature at least once, and hold three invariants the whole pass, whatever the failure: (1) never drive an instance you haven't health-checked since it last did something surprising — doctor before first drive, doctor on each fresh session where sessions are the unit, doctor again after any failed drive, and where doctor can't see the failure (a wedged UI state on a healthy process), reset to a known state or relaunch rather than hoping; (2) evidence captured so far survives every cleanup, checked at its named location, not assumed; (3) nothing a drive started outlives that drive's usefulness — failed-iteration residue is cleaned whether the session is stuck, exited, or shared (for a shared instance, clean the residue, not the instance). A doctor failure caused by skill drift is drift: fix it under edit scope and retry once — restart whatever the fix invalidated, nothing more — before calling the pass `blocked`. A feature that can't be reached is `verified-unreachable` only with the concrete prerequisite (auth, entitlement, OS, external state) and the route attempted; if the map omits that prerequisite, that's drift.

Bias to deletion and the smallest change that solves the problem. +- **Foundational Thinking.** Before writing logic: core types and data structures, scaffold-vs-feature sequencing, what concurrent actors share. +- **Redesign from First Principles.** Integrating a new requirement into an existing design. Redesign as if it had been foundational from day one. +- **Attack the Premise.** Two or more fixes that share one premise have failed the same gate. Write the premise down and test it directly before you write another fix that assumes it. +- **Subtract Before You Add.** Sequencing an addition, refactor, or rewrite. Remove dead weight first, then build on the simpler base. +- **Minimize Reader Load.** Reviewing or shaping code that's hard to trace. Count layers and hidden state, collapse one-caller wrappers, shrink mutable scope. +- **Outcome-Oriented Execution.** Planned rewrites and migrations with explicit phase boundaries. Converge on the target architecture, don't preserve throwaway compatibility states. +- **Experience First.** Product, UX, or feature-scope tradeoffs. Choose user delight over implementation convenience. +- **Exhaust the Design Space.** A novel interaction or architectural decision with no precedent. Build 2-3 competing prototypes and compare before committing. +- **Build the Lever.** Any non-trivial work. Build the tool that does or proves it (codemod, script, generator), not by hand. The tool is the artifact a reviewer reruns. + +**Architecture** + +- **Model the Domain.** Writing stateful logic, or code that branches a lot or repeats a shape assumption across files. Encode the domain in a structure (state machine, typed model, table or registry, reducer, boundary, the right collection) instead of scattered conditionals. +- **Boundary Discipline.** Wiring validation, error handling, or framework adapters. Guards at system boundaries, trust internal types, keep business logic pure. +- **Type System Discipline.** Designing types or a signature in any typed language. Make illegal states unrepresentable, brand primitives, parse external data at boundaries. +- **Make Operations Idempotent.** Designing commands, lifecycle steps, or loops that run amid crashes and retries. Converge to the same end state. +- **Migrate Callers Then Delete Legacy APIs.** Introducing a new internal API while old callers exist. Migrate and delete in one wave. +- **Separate Before Serializing Shared State.** Concurrent actors might write the same file, branch, key, or object. Eliminate the sharing first. + +**Verification** + +- **Prove It Works.** After a task, before declaring done. Verify against the real artifact, not a proxy or "it compiles". +- **Fix Root Causes.** Debugging. Trace each symptom back to the first place the system went wrong and fix it there. A guard is a fix only when the state it handles is legitimate. +- **Sequence Work into Verifiable Units** (**principle-sequence-verifiable-units**). Multi-step work (sweeps, migrations, runs of similar edits) and how you stack commits and PRs. Break work into small units that each end in a check, verify each before the next, and order delivery so the sequence proves itself. +- **Test Behavior, Not Implementation.** Writing, changing, or keeping a test. Assert what the code's users can observe, so the test fails when that behavior breaks and keeps passing when only the internals change. +- **Explain the Number.** Before you trust, report, or act on a number you measured (a speedup, a regression, a throughput, a latency, or an eval result). Find what limits it, and rule out that it measured something other than the work you think. + +**Delegation** + +- **Guard the Context Window.** Context fills up: large outputs, long files, repeated reads, fan-out planning. Route bulk to subagents, keep summaries in the main thread. +- **Never Block on the Human.** Tempted to ask "should I do X?" on reversible work. Proceed, present the result, let the human course-correct. + +**Meta** + +- **Encode Lessons in Structure.** You catch yourself writing the same instruction a second time. Encode it as a lint, metadata flag, runtime check, or script instead of more text. + +## Autonomy + +**Just do it.** Use any MCP tool. Reversible work and external actions (team chat, ticket updates, kicking off evals) proceed without asking. + +**Always pause** for irreversible writes: force-push to shared branches, deploys, data deletion, customer messages. + +**Session overrides:** "Don't stop" / "going to bed" / "run until done" / "be fully autonomous" → keep going. + +**No is an acceptable answer.** Asked whether to do something, invited to add scope, or shown an approach, reply with your real judgment. Decline, push back, or say "this doesn't earn its place" when true. A recommendation is a judgment, not a validation. Agreement is not the default, candor over sycophancy. + +## Subagents + +**Use `subagent_type: "poteto-agent"` for any subagent you spawn inside a playbook step** (code-writing delegates, ad-hoc helpers). The chat that receives `/poteto-mode` runs the playbook. Never spawn a `poteto-agent` to run the playbook itself. Routed workflow skills (`how`, `why`, `interrogate`, `reflect`, `swarm`) set their own `subagent_type` for diverse-model review. Respect what the skill prescribes, don't override to `poteto-agent`. + +**Defaults for every `Task` call.** `run_in_background: true`, agent mode (readonly strips MCP), file pointers not inlined context, explicit model per role (configurable via `/setup-pstack`. Defaults `grok-4.7-xhigh-fast` for code, `claude-opus-5-5-xhigh` for prose and judgment). Code delegates tier by difficulty. The hardest changes (cross-cutting design, gnarly concurrency, subtle algorithms) go to your strongest judgment model (`claude-opus-5-5-xhigh`), whether the task needs judgment on vague intent or is a precisely specified sequence of steps to execute to the letter. Trivial mechanical edits go to your fast code model. Per-role lines in the `/setup-pstack` rule override these defaults and the model choices in the routed skills (`how`, `why`, `arena`, `swarm`, `architect`, `interrogate`, `reflect`). A role with no line keeps its default, and a role line of `inherit-parent` or `auto` runs that role on the parent chat model (omit Task `model`). Each code playbook's configured model comes from its line (`feature, refactoring`, `bug-fix`, `perf-issue`, or `hillclimb`), and the hardest changes read `hardest tasks`. Prose and judgment read `judgment and prose`. + +**Match the model to the job.** Before each spawn, start from the role's line or default and pick the reasoning level and speed the job needs. The `/setup-pstack` budget sets each role's starting level, xhigh by default. Raise it one step, up to max, for the hardest or subtlest work. Lower it one step for judgment and two or more steps for routine work. Use fast mode only when the job is urgent, meaning CI or trunk is red or a person is blocked on the result right now. Otherwise use standard speed, the same slug without `-fast`. Verification is the exception and stays on the `swarm workers` model and speed (`grok-4.7-xhigh-fast` by default). Change only the effort level and whether the slug is fast, and keep the family the role names, so a diverse panel stays diverse. If the family has no slug at that level and speed, use its nearest slug. A role on `auto` or `inherit-parent` stays on the parent model. If the Task tool rejects the adjusted slug, do not try another adjusted slug. Use the role's line or default and say so. + +You own every subagent's work. Review the diff and write your own summary, don't pass through what it said. A second opinion is the same prompt against a different model. Agreement is high-signal. + +**Fresh subagents by default.** Give new work to a fresh subagent with consolidated scope, meaning the original brief, every later directive, and the prior agent's report and branch. This holds for a fix round, a follow-up, a retry, and the next queue item. Resume, message, or queue a follow-up on an existing subagent only when the new work strictly needs state that lives in that agent and is costly to move: its local checkout, its uncommitted changes, or a process it still runs, such as a dev server, a simulator, or a babysit watcher. A stop or hold order to a running agent is not reuse. A role such as a PR owner outlives its agent. Once that agent returns, a fresh agent takes the role's next round.

Where this playbook says to report a rebase, that owner rebases its own branch and publishes it with `git push --force-with-lease` per `playbooks/autopilot-full.md` step 2. In Autopilot-stack, the root is that owner.

A conflict is the one blocker you report rather than resolve. Say which branch needs the rebase and stop. Do not fall through to CI to look busy.

On GitHub, status comes from `scripts/watch-pr/watch-pr`. Run it directly. It emits JSON by default and accepts `--pretty` for humans. In `check` mode pass `--status-only`. The bare command polls until a terminal verdict, which is `drive` behavior. On Origin, use `origin pr view <pr> --checks --comments`, `origin pr thread list <pr>`, and `origin pr checks <pr> --watch`. Re-read the PR and threads whenever the check watch returns.

Revise the list only for the sanctioned follow-up PR from step 4. Append it at the end, drop the merged owner, and rearm with the corrected snapshot. +7. **Classify CI before any retrigger.** Flake or infrastructure earns one fresh build, never a job retry. One retry only. An identical second failure means it was never flake, so reclassify and read the child logs instead of retrying blind. A failure in code the diff never touches means a stale base, so check with `git merge-base --is-ancestor` before assuming flake. Report a stale base as needing a rebase instead of burning retries. Only a failure in the diff's own code gets a commit. +8. **Bugbot is triaged skeptically, always.** Verify each claim against the code per `../references/bugbot-triage.md`. Fix real findings with a red-first proof in the lowest PR that owns the code, never at the tip unless the owning PR has merged. In that case, use step 4's sanctioned follow-up PR. Per step 2, upstack fixes wait for step 5's next frontier-driven push wave. Push that wave before replying so the reply cites the commit. On Origin, reply with `origin pr thread reply <thread-id> <pr> --body-file <reply-file>`. On GitHub, call `gh api --method POST "repos/<owner>/<repo>/pulls/<pr>/comments/<comment-id>/replies" --input <payload.json>` and put the reply body in the JSON file as data.

Frames, authors briefs, drains the inbox, owns the human report, makes judgment calls. It never authors or edits code. Conflicted merges, chain rebases, and code changes are always tasks. Mechanically landing a verified unit (fast-forward or clean cherry-pick of a worker's commit, then push) is bookkeeping the coordinator may do itself on repos where local git is cheap. Queueing finished work behind an idle stacker is how a deadline harvests nothing. The loop is agentic end to end. Agents are spawned, resumed, and drained only through the Task tool. Pick each subagent's reasoning level and fast or standard speed for the job, per the Subagents section. State reads and writes go through `scripts/orch/orch.ts` at drain points, one command in and one line out. The CLI never spawns, waits, or wakes anything. +- **Sub-coordinator.** Always local, durable, one per track, and only when the program exceeds what one coordinator's drains can manage. A track the coordinator can drain itself needs no middle layer. Each nested layer re-pays a full orientation preamble, and a blocking sub-coordinator hides its children while the parent idles. Owns its track's units and boards, authors its workers' briefs, spawns its own workers and verifiers (nesting works to depth 3, and a nested spawn has the full Task schema including `environment`). Rolls up aggregates at wave boundaries. Never forwards raw child reports. Cap in-flight children at what one drain can process, roughly ten, as a rolling window. Never as blocking batches, which cost the slowest child of every batch. +- **Worker / verifier.** Always `environment: "cloud"` unless the task needs this machine: `control-ui` or `control-cli` runtime verification (from `cursor-team-kit`). Reading local transcripts under `agent-transcripts/`. Simulators and local IDE state. Auth that exists only here. Cloud agents cannot read the local store, so their briefs inline what they need or point at repo paths. Prefer fewer, broader workers. One writer per worktree or branch (principle-separate-before-serializing-shared-state). Run a unit's verifier on a different model family from its worker. + +Depth stays at coordinator, track, worker.

Paste it verbatim into every spawn and every resume. Directives decay across resumes, and each dropped one costs a human turn. When you catch yourself restating an instruction, append the line before you act (principle-encode-lessons-in-structure). +- `overview.md` is the durable PR and issue DB. Append. Never rewrite wholesale per event. +- `units.tsv` has one row per unit: id, track, state, branch, PR, head SHA, brief path. Update rows in place. +- `frontier.json` is the computed merge frontier, per Stack safety. +- `ledger.tsv` is the verification ledger, per Verification. +- `inbox/` holds completion pointers. `gates.md` parks human gates (question, options, default on no answer). +- `decisions.tsv` is the trail via the show-me-your-work skill. +- `status.md` is derived from `units.tsv` and `ledger.tsv` at each drain, never hand-maintained.

Verbatim paste is for cloud spawns and every resume. + +A sub-coordinator brief adds its track boundary and unit list, its spawn budget with the cloud default and the local exception list, the drain protocol, and the rollup format (per child: name, status, PR, head SHA, verdict, one line, plus track status and frontier delta). + +A dependency is a context relay, not just ordering. Undeclared upstream context makes the worker guess. Missing fields are a refuse-to-spawn condition. Audit one sampled worker brief per sub-coordinator per wave, concurrently with the wave it samples, never as a gate in front of it. A failing brief stops that track and fixes the sub-coordinator's instructions, not just the worker, because brief quality decays late in a run. Never resume-chain a brief. Respawn fresh with consolidated scope. + +#### Steps + +1. **Frame.** State the done predicate as something countable ("all 126 units merged, each ledger-verified `unit-test-verified` or better"). Quantify scope: units, rough effort, expected stacks, and the wall-clock budget. If one agent could finish inside that budget, stop here and run Autonomous run instead. Collapsing must not depend on another document being present. It means do the work directly in this session, plain workers where they help, verification inline, landing as you go, and none of the store, register, or pilot machinery below. Schedule landing against the budget. By roughly 70% of it, stop spawning and land what is verified. Name the tracks per project. A contested decomposition or one-way door goes through the arena skill before the pilot. Present the framing once. Reversible prep proceeds without waiting. +2. **Install the runtime.** Run `orch init`. Open the trail via the show-me-your-work skill, write the standing orders before any spawn, and seed `frontier.json` from existing PRs with `orch frontier set --repo <repo-dir>`, adding `--forge origin` when the forge is Origin. +3. **Pilot.** Push one unit through the whole path: brief, worker, verification, stack entry, ledger row, merge. The pilot exists to falsify the brief template, the verify recipe, and the unit size while that costs one agent instead of fifty. Fix the contract from pilot evidence before any fan-out. Scale the pilot to the unit. On programs of near-identical cheap units, the first unit is the pilot, run as a normal unit with its verify command inline, and fan-out starts the moment it lands. The dedicated pilot pipeline (separate verifier agent, audit gate) is for expensive or novel unit shapes, not for clone-units where a serialized pilot has nothing to falsify. +4. **Scale.** Spawn a rolling window of workers up to the in-flight cap, refilling as children finish. Blocking batches pay the slowest child of every batch. Spawn track sub-coordinators only past the one-drain threshold in Roles. Recompute ready work after each drain. Relay upstream reports into downstream briefs. Keep sibling communication upward only. The sampled brief audit runs alongside the wave it samples and stops the next refill on failure, not the current one. +5. **Drain.** Run the queue discipline below at every drain point. +6. **Land.** Landing is continuous, never a terminal phase. Integration starts with the first verified unit and runs alongside the remaining waves. On heavy repos the stacker is a standing role from wave one, integrating as units verify. On repos where local git is cheap, the coordinator lands verified units itself per Roles. Keep the frontier green before upper-stack work. Stack safety governs. Advance `frontier.json` only on merge or reported new head SHAs. +7. **Close.** Drain the final inbox, reconcile every spawned agent to a terminal row (done, abandoned, zombie-reconciled), confirm the predicate on the real artifact, confirm every landed PR has a verdict for its current head SHA, audit the trail per show-me-your-work including its cross-model review, encode recurring corrections into `preferences.md` or the brief template. Leave the store intact. It is the postmortem. + +#### Queue and drain + +- On a completion notification, run `orch inbox push <agent> <unit> <status> [--report PATH]` and return to what you were doing. Never deep-review inline. A completion that needs review becomes a verifier unit. Never review a diff inside a drain. +- Drain in batches at four points: the end of a critical section, a track rollup, a frontier watcher wake (arm it via the loop skill, with a long heartbeat fallback), and before a human report. Begin each batch with `orch inbox drain`. Arrivals during a drain wait for the next one. +- Critical sections you finish first: authoring a brief, a stack operation, a conflict decision, writing a gate, updating ledger or frontier. +- Each drain classifies every pointer (landed, needs-verify, failed, zombie, noise), writes the resulting rows through `orch unit add`, `orch unit set`, and `orch ledger record`, runs `orch status`, then spawns the next wave in one message. +- Account for every spawned child at its track's rollup: arrived, respawned, or its scope explicitly absorbed. Silently redoing a missing child's work hides both the wasted spend and the coverage gap its result existed to close. +- A drain turn ends with the three lines from `orch status`: counts against the states, what changed, gates open. Detail lives in `status.md`. The full reply contract applies at checkpoints and close. + +#### Stack safety + +- The frontier is a computed object, never narrative. Recompute `frontier.json` after every merge and stack mutation: ordered PR list, branch names, head SHAs, a generation number, the lowest unmerged PR. The command walks the PR base chain through the checkout's current branch, so chain order and PR states come from the forge. It uses `gh` by default. Pass `--forge origin` when the program resolved the forge to Origin. Head SHAs come from local branch refs, so resolve it from the stacker's clone. A branch with no PR errors rather than guessing. +- Exactly one stacker per stack may mutate topology (chain rebases, force-pushes, base retargets, merges), serialized within its stack. Record the holder in the standing orders. Chain rebases run in cloud. A local rebase at this scale takes the laptop down. +- Workers never rebase and never retarget or merge PRs. Babysitters follow `playbooks/babysit.md`, one per stack, scoped to one immutable frontier generation. They report conflicts to the stacker rather than rebasing. +- PR closes and retargets go through the stacker only. Closing a base PR orphans every chain above it. Merges and stack surgery are units with briefs like any other. +- One retro watcher follows merged PRs for reverts, post-merge CI breaks, and orphaned follow-ups. + +#### Verification + +Scale verification to the unit. When VERIFY is a single cheap command, the worker runs it and reports the output, and the coordinator spot-checks receipts. A dedicated verifier agent (on a different model family than the worker) is for units whose verification is expensive, judgment-laden, or high-blast-radius. A verifier agent whose entire product would be rerunning one command is ceremony, not verification. + +Write ledger rows with `orch ledger record`. Check the current PR and head SHA with `orch ledger check`. `ledger.tsv`, one row per verdict, keyed by PR number plus head SHA: `live-ui-verified | unit-test-verified | type-check-only | verifier-blocked | verifier-failed`. CI green is an input to a verdict, not a verdict. Behavioral work needs better than `type-check-only`. `verifier-blocked` is not a pass. Respawn when the environment heals. `verifier-failed` gets a fix unit, not a re-verify. A worker may self-report. A verifier overrides it on the same key. A new head SHA voids the row, so re-verify after restack. The ledger answers "was this verified", not memory and not the transcript. + +A unit is not done until its output is externalized the moment it lands, never batched to the end of the run. A worker pushes its branch, a verifier writes its ledger row, receipts land in the store. Work that exists only on one VM when that VM dies was never done. + +#### Liveness and failure + +- Never resume an agent to check on it. A resume restarts an idle agent. Probe read-only: the ledger, `units.tsv`, `gh`, pushed branches, the cloud agent's status in the Cursor dashboard. Transcript mtime is not liveness. +- A silent death gets a synthetic postmortem row in the inbox (unit, failure mode, last evidence, options). Replan on evidence as it arrives. Never wait for full quiescence. +- Retry by mode: cap-hit or oom, respawn with smaller scope. Network-drop, retry as-is. Tool-error, retry on a different model. Unknown, retry once. Two retries, then abandon the unit and replan around it. +- A zombie that returns hours late reconciles against the current frontier and ledger before anything is accepted. Salvage unique findings through a fresh unit, never a blind merge. +- When continued spawning would produce garbage tree-wide (bad upstream output, broken acceptance, dead infra), write a stop line at the top of the standing orders, let in-flight work finish, fix the cause, clear it. +- Bound your own infra retries the same way you bound a child's. After a few consecutive tool aborts, stop retrying. Write a terminal handoff to durable state (what is done, where it lives, the exact command to resume) and end the run. +- After a Cursor restart: local agents are dead, cloud work is not. Re-read the standing orders and `units.tsv`, recompute the frontier, reattach cloud work by PR and branch rather than agent id, respawn one sub-coordinator per track from its stored brief plus current state, drain, resume. The dead session's store lock clears itself on the next write. `orch` replaces a lock whose holder pid is gone. + +#### Escalation + +Reaches the human, batched into the status page rather than per item: irreversible actions (force-push to shared branches, deploys, deletions, closing someone else's PR), genuine product or preference calls no experiment settles, a standing order that contradicts observed reality, a program-level dead end that survived a replan. Park each as a `gates.md` entry before asking, and route work around it. + +Never reaches the human: frontier nudges, rebase mechanics, retries, CI flake triage, review-thread triage, format fixes, scope the brief already forbids (refuse and continue), and "should I keep going".

Green CI and an approving bot review are not verdicts, because neither runs the change as a user would. +2. **Land only the contiguous verified run rooted at the bottom.** Walk up from the lowest unmerged PR and stop at the first one without `PASS` or `PASS+NOTES`. The PRs below it are the run, and the top one is the ceiling. A verified PR above an unverified one waits, because it cannot land without the code below it. One whose branch neither holds nor needs that code can move onto trunk and land on its own. It needs a fresh verdict first, because its old one ran with that code beneath it and trunk does not have it. +3. **Re-check that the verdicts still describe the code.** A verdict covers a patch, and a chain rebase moves every PR above it to a new SHA without failing any check. Compare `git patch-id` at the verdict SHA with the current head before trusting an older verdict. When the patches differ only in tests, docs, or lint config, a lane's result stands if what it ran builds the same at both SHAs apart from noise. Noise is a difference that also shows up between two builds of the verdict SHA, or an embedded commit SHA. Report each kind of noise with its files, so a reader can check the call. The change itself still gets fresh checks and a review, because the old verdict never saw it. A lane with no build output, such as a dev server, cannot show this, so rerun it, and re-verify anything else that drifted. +4. **Land bottom-up, one PR at a time.** Always merge the run's lowest unmerged PR, with `origin pr merge <pr>` or `gh pr merge <pr> --squash`. On Origin the plain command also merges every PR below the one you name, and on GitHub a PR whose base is still its parent's branch merges into that branch, not trunk. Read the PR back for the result (`origin pr view <pr>` or `gh pr view <pr> --json state,mergedAt,baseRefName`), because a merge command can report success when a merge queue only queued the PR, and a requested auto-merge is not a merge. A landed PR reads merged with trunk as its base, not its parent's branch. Arm `--auto` (Origin merge-when-ready or GitHub auto-merge) only on a PR whose verdict covers its current head, because it lands whatever head is ready. After a merge lands, retarget the PR whose base was the merged branch to trunk (`origin pr edit <pr> --base <trunk>` or `gh pr edit <pr> --base <trunk>`), move its patch onto the merge result, and push with `--force-with-lease`. The verdict covers the patch, not its commits, so step 3's patch-id rule decides whether the verdict survives. Merge it once its checks pass and its verdict survives. +5. **Leave the stack alone while it lands.** Step 4's move of the next PR is the only change to a branch or base, because a merge lands whatever its branch and base hold at that moment, verdict or not. On GitHub, watch the run with the queued watcher from `playbooks/babysit.md` (`scripts/watch-pr/watch-pr --queued-stack --stack-prs <bottom-to-top>`) under `/loop` until it reports `COMPLETE` at the ceiling. On Origin, re-read the current PR with `origin pr view <pr> --checks` each time `origin pr checks <pr> --watch` returns, until the ceiling reads merged. A base that moves to trunk when its parent merges is expected, not damage to repair. If a merge stalls, find out why before you change anything. +6. **Stop at the ceiling.** Extending the run takes new verdicts, so it is a new pass through step 1. + +**Reply:** the verified run and its ceiling, each PR's verdict and who produced it, what landed and how you confirmed it, and what the next gap needs. diff --git a/packages/pstack/upstream/skills/poteto-mode/playbooks/trace-forensics.md b/packages/pstack/upstream/skills/poteto-mode/playbooks/trace-forensics.md new file mode 100644 index 0000000000000..bf1b003786503 --- /dev/null +++ b/packages/pstack/upstream/skills/poteto-mode/playbooks/trace-forensics.md @@ -0,0 +1,14 @@ +### Trace forensics + +**You own the diagnosis from the artifact.** + +Distinct from **Runtime forensics**, which instruments the live process.

The effort token is the last token, or the one before a trailing `fast`, on the ladder `max` > `xhigh` > `high` > `medium` > `low`.

Grok slugs top out at `xhigh`, so under `unlimited` the fallback puts Grok at `xhigh` and keeps `grok-4.7-xhigh-fast` as it is. `large` keeps both defaults. `small` turns them into `claude-opus-5-5-medium` and `grok-4.7-medium-fast`. + +**(c) Show the roles and confirm.** Show every role with its model, marking any real slug not in the detected set as needing a choice.

That reads unrelated private chats. Walk this run's rows against what actually happened.

When a row records neither a real decision nor a real action, or its claim or evidence is wrong, add a row that supersedes it with what actually happened and a pointer that resolves.

The scripts call that person the reader, as in `readerActions` and reader steps. The reader decides whether the behavior is right. The reader can be a PM who reads a product flow, an engineer who reads a protocol or a service, or a reviewer who reads a design. Label each state with what the reader can observe or cares about, such as "Paying" in an app or "Lease held, write pending" in a lock service.

The command writes its files next to its input. The first run installs TLC and Java with mise, which downloads about 305 MB and needs the network. The help's TLC section tells how to use a TLC and Java that you have. + +## Pick the direction + +Use `from-spec` when a TLA+ model exists, or when the code or design is concrete enough to model. Use `from-chart` when there is no model, and the people who own the behavior should agree on it before anyone builds or changes it. + +If the code already has a TLA+ spec, start from a copy of that spec. Add the variables that the labels and rules need, and keep the spec's existing invariants. To audit the code against that spec, make the copy model what the code does, and pass the spec unchanged as `--against`. Check it with the config that its authors say it passes, and pass that config as `--against-config` unless it has the spec's file name. One mapping labels both models, so label states and steps from variables that both have. A label that reads a variable that only the copy has must test `"name" in v` first, and label the spec's states another way. When a model describes code, tie every variable and action to code that a reviewer can open, and take its name from that code. Make each action one indivisible step in the code. Put the file and line of the code that checks each condition of an action in a comment on that condition, as in `\* pay.ts:120`. + +## Spec to chart + +1. Choose the chart's states. When the reader cares about something that a label would hide, put it in the label, such as "Paying, charged twice" when the screen still says "Paying" after a second charge. Start with few states. Split a state when the split separates two bugs, or when the reader must see a step that leaves the label the same, such as a request that reads a count, because the chart does not draw such a step. +2. Write each rule that the reader agrees to as one invariant, with the reader's sentence as its comment. A rule can be about any state in the model: what a screen shows, what a request returns, a stored value, or a message between parts. When the model describes code, the rule also names the code that can change that state. If the model has no variable for what a rule is about, add the variable. Do not drop the rule. For a rule that applies once everything settles, define `Settled == ~ENABLED System`, where `System` is the disjunction of the actions that happen without the reader. For a rule that applies at a narrower point, such as after each request finishes, write a predicate for that point and make the rule hold where it is true. For a goal that the system must be able to reach, write a rule that says the goal never happens, and pass that rule with `--expect-broken`. The path that breaks it is then a way to the goal. The chart still draws the goal as a state that breaks a rule, and `stories.md` tells it as a bug, so name each goal rule in the hand-off. Report each other broken rule as a bug. Never weaken a rule to make the chart pass. +3. Run `from-spec`, then fill in the mapping file it writes. Put the labels in `state` and `step`. When the chart must separate what the reader does from what happens around the reader, list the reader's actions in `readerActions` by action name. Leave the list empty when every action counts the same. When the overview is too large to read, add `--cover`. The overview then keeps only the shortest path to each settled state, plus every bug path, and the command lists what it leaves out. When two bugs end in the same state for different reasons, add `cause` and make it name each reason. To color the states by what the reader cares about, such as "Order shipped", return that group from `group`. The legend names the groups, and in the PNG a state that breaks a rule is red in place of its group color. +4. If there is a proposed fix, model it and pass that model as `--fixed`. +5. Render each chart with `--png` and look at every PNG. Check that each numbered path reads in order. If a label reads like code, fix `state` or `step` and run the command again. +6. When the model describes code, replay each bug's story against the real code, as a test or a live repro, one step per model action. Drive only entry points that a user, a client, or another part of the system reaches, and assert only what they can observe. A test that asserts a flag that it sets, or that searches the source text, proves nothing. When a run proves part of the story and reading the code proves the rest, say which part each proves. When the test copies code that it cannot import, give the commit and line range of the copy, and list what the copy leaves out. If a bug does not reproduce, assume the model is wrong until you show otherwise. Fix the model, not the rule. For a design with no code yet, the TLC trace is the evidence, and the hand-off must say so. + +## Chart to spec + +1. Draw the chart that the reader agrees to. Use one region for each part that changes independently, such as a device's connection and the job that the device runs. Add one `%% never` line per rule, with the reader's sentence. Draw an event that stops or restarts a part, such as "the app closes" or "the process restarts", as an edge to the state that comes next. Run `render CHART.mmd` to get a PNG of the chart for the reader. +2. Run `from-chart`. If a rule breaks, the agreed chart has a design bug. Take the bug to the people who agreed to the chart. +3. Add the real code's guards and variables to the spec that `from-chart` wrote, and run `from-chart` again. For each difference it prints, ask the reader whether the code is wrong or the chart needs a correction. + +## Hand off + +Give the PNG and the Mermaid source of each chart to the person who must decide. Add one line per bug with the rule it breaks, its steps as the chart numbers them, whether it reproduced, and whether the proposed fix fixes it. A broken PROPERTY has no path on the chart, so give the TLC counterexample that `stories.md` names for it. With `--against`, also say whether the spec already lists it: in the configs that `stories.md` names, in the spec's notes on what the model leaves out, or not at all. When the model describes code, do not report that a rule holds while the command lists conditions with no file and line. Take every count you quote from `summary.json`. Attach `stories.md` and the command that regenerates everything. Say what the model leaves out. diff --git a/packages/pstack/upstream/skills/statechart/scripts/bug-states.mjs b/packages/pstack/upstream/skills/statechart/scripts/bug-states.mjs new file mode 100644 index 0000000000000..3c8e9f21f6046 --- /dev/null +++ b/packages/pstack/upstream/skills/statechart/scripts/bug-states.mjs @@ -0,0 +1,81 @@ +import fs from "node:fs"; +import { BROKEN_MARK, parseValue, stateKey } from "./lib.mjs"; +import { SEP } from "./chart-parts.mjs"; + +export function firstBad(raw) { + const badStates = new Map(); + for (const t of raw) { + if (!badStates.has(t.invariant)) badStates.set(t.invariant, new Set()); + badStates.get(t.invariant).add(stateKey(t.steps[t.steps.length - 1].vars)); + } + const cuts = []; + const seen = new Set(); + for (const t of raw) { + const first = t.steps.findIndex((s) => badStates.get(t.invariant).has(stateKey(s.vars))); + const cut = { invariant: t.invariant, steps: t.steps.slice(0, first + 1) }; + const id = `${t.invariant}${SEP}${stateKey(cut.steps[cut.steps.length - 1].vars)}`; + if (seen.has(id)) continue; + seen.add(id); + cuts.push(cut); + } + return cuts; +} + +export const byOrder = (a, b) => + a.steps - b.steps || + a.trace.steps.length - b.trace.steps.length || + (a.id < b.id ? -1 : a.id > b.id ? 1 : 0); + +const lastKey = (t) => stateKey(t.steps[t.steps.length - 1].vars); +export const badOf = (raw, rule) => new Set(raw.filter((t) => t.invariant === rule).map(lastKey)); +export function reachableAvoiding({ graph: g, stateKeys }, bad) { + const ok = (id) => !bad.has(stateKeys.get(id)); + const next = new Map(); + for (const e of g.edges) { + if (!next.has(e.from)) next.set(e.from, []); + next.get(e.from).push(e.to); + } + const clean = new Set([...g.nodes.values()].filter((n) => n.init && ok(n.id)).map((n) => n.id)); + for (const id of clean) for (const to of next.get(id) ??

A run writes its + files in a temporary folder, and then replaces the whole output folder with + it. When runs overlap, the output folder has the files of the run that + finished last. The command does not use an output folder that has files that + it did not write. On a filesystem that cannot rename, the command copies the + files into place, and overlapping runs can mix their files. + --png Also draw each chart as a PNG. The PNG section tells how. + --theme NAME The colors of each PNG: light, dark, or classic. Default: light. It needs + --png. + -h, --help Print this help, and exit 0. + +Output + The command prints whether each rule holds, the chart's counts, and one story per bug. + from-chart also prints the comparison. The command writes these files in the output folder: + chart.mmd The overview. + bug-N.mmd Only the steps of bug N, numbered. Bugs are numbered by fewest reader steps, + then fewest model steps, then rule name, then cause. Bugs that only the + --fixed or --against model has come last. + bug-N-developer.mmd, bug-N-layered.mmd + The path of bug N through the developer's states, when the mapping exports + detail(). The layered chart puts each detail state in a box named by its + state label. A state with a blank detail stays a plain state. + stories.md One entry per bug: the rule, why it breaks, the steps that lead into it, the + shortest path in reader steps, and what the --fixed or --against model does + instead. The rule's sentence is the \\* comment lines above the rule in the + spec, or in a module in its folder that the spec EXTENDS, directly or + through another module. With --fixed or --against, the other spec and its + modules count too, after SPEC.tla and its modules. The entry numbers each + step that changes the state label, each reader action, each step that + changes a variable that the rule reads, and the step into the bug. Between + them, it counts the hidden steps and names each different step once. Above + the steps, a line names up to five different steps that lead into the bug, + most common first, and counts the rest. When more than one step or start + state leads into the bug, the entry says that the path is the shortest that + TLC found. A step leads into the bug when it goes there from a state that + keeps the bug's own rule. That state can already break other rules. "(the + state stays the same)" marks a step on that line that keeps the state's + label and is not on the bug's path. from-spec does not draw such a step. + When TLC names the steps only after the whole next-state action, the entry + cannot count them. Then one line per broken PROPERTY with its sentence, + which comes only from its own spec file, the reader states that repeat + forever, if any, and the TLC output that has its counterexample. + summary.json The counts behind the chart. Each bug has counterexamples, how many model + states end it, each with its own TLC trace; lastSteps, the steps that lead + into it, most common first; and startsHere, whether a start state is in it. + brokenProperties has each broken PROPERTY, its rule sentence, the reader + states that repeat forever as repeats, and its TLC output. mixedStatus + lists the states that break a rule in some cases. chartGroups counts the + drawn states of each group, and mixedGroups lists the states in more than + one group. With --cover, cover lists the states and arrows that the + overview leaves out. With --fixed or --against, uncited has the conditions + with no file and line for each code model. With --against, second.listed + has what each config beside AGREED.tla expects, and each bug has the + configs that list it. + tlc/ The config and the TLC output of each run. When the overview has regions, + from-spec also writes tlc/regions-all.mmd, the regions with every arrow, and + tlc/regions-proof.mmd, every state and step of TLC's graph in one region. + compare-charts.mjs tlc/regions-all.mmd tlc/regions-proof.mmd repeats the + proof. It prints "same" and exits 0, or prints each difference and exits 1. + *.png Each chart as a PNG, with --png. A run without --png deletes them. + +Reading a chart + from-spec draws the overview as two parallel regions when every state reads "context: progress": + the contexts on one side, the progress on the other, both at the same time. It does so only when + that has fewer states, when the regions combine back into exactly every state and step of TLC's + graph, and when each state's color is the worse color of its two region states. Otherwise it puts + the states of one context in a box named context, and prints why. Each state in a box shows only + its progress, and a context with one state stays a plain state. + Regions draw only the arrows of the shortest way to each state, of each bug path, and of the + nearest step with each label. The script checks that these arrows make no step that TLC's graph + does not have. At a step that they make wrongly, it puts back every arrow that the full regions + take there. + An arrow from a box's border leaves from every state in the box. The chart draws it only when + every state in the box takes the step with the same labels to the same state, and no state + outside the box has the box's name. + In regions, a step leaves every region that has it. "[when A or B]" or "[unless A or B]", + whichever is shorter, says which states of the other region the step needs, and a "%% when" or + "%% when not" line under it lists their ids. A loop says the region may also stay. + Other words in [ ] come from the mapping's guard(), and "after N s" from its timer(). An edge + shows guard() words only when every model step behind it has them. In regions, they replace + "when A or B" and "unless A or B". TLC does not check them, and has no clock, so a reviewer + checks them against the code. + Gray states work. Red states break a rule. An orange state breaks a rule in some cases: a model + state under its label breaks a rule, and a path without a bug reaches another one. A white state + is reached only after a bug: every path from the start to its model states passes a state that + breaks a rule, and none of them breaks one. With --fixed, red, orange, and white describe the + fix, and green states are fixed by it or exist only with it. A purple state breaks a rule only + with the fix: today it works, is reached only after a bug, or does not exist. With --against, a + state takes the worse of its two models' colors, red, then orange, then white, and green states + exist only in the spec. + When the mapping exports group(), the fill is the state's group, which the legend names. A chart + state is in a group when all its model states are in it, and a region state when every state + that it is part of is in it. A state in no group, or in more than one, is gray. The legend lists + the groups that the chart draws: first the groups in groupColors, in that order, then the others + from A to Z, and then each status border that the chart uses. groupColors gives a group a light + "#rgb" or "#rrggbb" color. A group with no color takes the next free palette color: light blue, + orange, purple, yellow, teal, tan, then pink. A group cannot have the name of a status, such as + "Breaks a rule". Without group(), the legend shows only the statuses that the chart uses. In the + .mmd file, the status is a thick border of its color, gray for a white state, on top of the group + fill. In a PNG, a red, orange, purple, or white state is a box of that color with a border and + text of its color in place of its group fill, and a fixed state is a green box, so each box shows + one signal. + A thick blue border and numbered labels mark the bug. With group(), and in a PNG, the blue border + marks only the states on the bug's path that work, and the numbered labels show the rest. + Mermaid state diagrams cannot color an edge. + Each bug replays on the other model by its state labels and step words, which are what the + reader sees. The replay takes the bug's own steps. Between them, it also takes the other model's + steps of actions that SPEC.tla's state graph does not have, when they keep the state label, are + not reader actions, and change no variable that the broken rule reads. A bug step that the story + hides must keep the state label on the other model too, unless that model cannot take it. A step + that the reader sees takes a step with the same words between the same two state labels, and + prefers a step of the same action. A hidden step of an action that the other model does not have + is skipped. A step that the reader sees of such an action takes any step to the same shared state + when it changes a shared variable, or else a step with the same words between the same two state + labels. + A label "with the fix, STEP" or "in the spec, STEP" is a step that only the other model takes. On + a bug's path it leaves the state before the first step that the other model shows the reader + differently, and ends where that model goes instead. The story quotes the other model's words + when they differ. "with the fix, STEP cannot happen at step N" or "in the spec, STEP cannot + happen at step N" loops on the state where that model stops the step, on an arrow of its own. On + the overview, the label ends with "of bug M". Outside regions, two states otherwise have at most + one arrow between them. Its lines are the numbered steps, then SPEC.tla's steps, then the other + model's steps, with a blank line between each group. + The other model may have other variables, record fields, and actions. The comparison leaves out a + variable or field that no state of one model has, in its state graph or its traces, and one whose + values never have the same type in the two models. One mapping draws both models, so it may read + only what both have. The command stops when the mapping reads, on a state of the other model, a + variable or field that no state of that model has, or one whose value has a type that SPEC.tla + never has there. It also stops when the mapping lists the fields of such a state, as a spread, + Object.keys, or JSON.stringify does. Test "name" in v before the mapping reads a field that the + other model lacks. The command also stops when a label, guard, group, or cause that the mapping + makes for the other model has the word "undefined" in it. + A chart with another model has the line "%% second model (fix|against): LABEL" right after + stateDiagram-v2. Each chart starts with front matter that keeps Mermaid from shrinking it to the + page or wrapping its labels again. + An edge lists every step that takes it, most common first. Words that the steps share at the + start are written once, as in "you tap Pay or Back". + +Regenerate + List every rule that is known to break with --expect-broken, the goals and the known bugs. Each + run then exits 0 until a rule changes, so one script rebuilds every chart and stops on any change: + set -e + node statechart.mjs from-spec Code.tla --against Agreed.tla --expect-broken NoLostUpload --png + A run that leaves a broken rule out of --expect-broken exits 1, and set -e stops the script there. + +TLC + TLA2TOOLS is the path to tla2tools.jar, and JAVA is the path to the java binary. With only + TLA2TOOLS set, the command runs java from PATH. Otherwise it uses TLC 1.7.4 and Java temurin-25 + from mise, or JAVA when it is set, and installs what is missing with mise. The first install + downloads about 305 MB and needs the network. It checks the checksum of tla2tools.jar. mise runs + in an empty temporary folder, so the mise files around the spec, in a repo, or above TMPDIR do + not apply, do not change, and need no trust. When mise cannot start or fails, the command prints + why, the install command, and how to set TLA2TOOLS and JAVA instead. + When the command starts, it copies its input files, which Exit codes lists. TLC checks the + copies, so an edit during the run does not change what TLC checks. + TLC checks each rule with one worker per CPU. When a rule is broken, TLC checks it again with one + worker, which finds the shortest bug paths, the same on every run. The command then prints how + many times TLC ran and how long that took. + TLC can find that a rule is broken and then stop on an error, such as a Java exception. The + command then keeps the paths that TLC printed, marks the rule broken, and warns that the charts + can miss states that break it. A smaller constant can let TLC finish. + +Exit codes + 0 Every rule holds, or exactly the --expect-broken rules break. from-chart also draws CHART.mmd + back unchanged. + 1 Another rule is broken, an expected rule holds, or the chart that the spec draws is not + CHART.mmd. The output says which. + 2 The command cannot finish: a bad argument, a missing file, a chart or TLC output that it + cannot read, no TLC, a helper script that cannot start, an output folder with files that the + command did not write, an input file whose content changed during the run, a new mapping to + fill in, a mapping that it cannot use, a renderer that --png cannot install or load, or a + chart that --png cannot render. + When a chart does not render, the command keeps the files it wrote and exits 2, whatever the + rules give. Otherwise, exit 2 does not change the output folder, unless the command moved it + aside and cannot put it back. Then the message names the folder's new path. When the command + stops after TLC has run, it keeps the files that it wrote, TLC's output among them, in a + temporary folder, and the message names it. When TLC's state graph is too large to draw, the + command prints whether each rule holds and exits 2, whatever the rules give. It stops TLC as + soon as the graph passes that size. The input files are the spec and config, the --fixed or + --against spec and config, the chart, and the map. Each .tla file in the same folder that an + input .tla file EXTENDS or INSTANCEs is an input file too, and so is each file that an input + .mjs or .js file imports by a relative path. Before --png renders, and again before it writes + the output folder, the command compares the content of each input file with its content at + the start.

Run both for a subsystem, maybe one is enough for a small change. Keep `why` narrow by default since its full sweep is slow. Put the narrowing in the ask itself (a scoped question, git plus a source or two) so `why` records the skipped categories per its own contract, and widen it only when the reasons are the point. +3. Start with a plain definition. Name the thing and say what it is in general terms, the way a senior engineer would say it out loud, with its common name if it has one. Then tie it to the case in front of you ("in X, we use this to ...") and build from there: how it works, the deeper reasons, the edge cases. For each part, explain the idea so it clicks: the problem it solves and how it actually works. Walk through what happens as the person does the thing (opens a long chat, scrolls up) when that is what makes it land. Listing functions and constants is reference, not teaching. Don't print framing labels ("the one idea to hold onto", "the thing to walk away with", "the key insight", "at its core", "TL;DR").

Just say it. When you would pause, stop and let them respond. Running one-shot with no live human, deliver it cleanly and put any offer to go deeper at the end. +5. Show, don't only tell, and build the picture up diagram by diagram. Open the diff, the code, or the debugger when that is the fastest way to land it. Draw when a picture lands faster than words.

Draw a short series instead, where each diagram redraws the last and adds a single part, so the reader watches the system assemble. A single all-at-once diagram, especially one saved for the end, is a reference, not teaching. Concretely, to teach a flow from A to B to C, draw it three times. First A to B. Then redraw and add C. Then redraw and add the return edge or the next piece. Match the medium to the idea, and use both kinds when both help. A mermaid diagram fits a flow or structure where the labels carry the meaning. When the idea is spatial, like layout, overlap, scroll position, or a before and after, reach for the image-generation tool and draw it marker-on-whiteboard style with a few short labels, since image models garble long text.

Ask what the sentence tells the reader to do or know, then write that. If you can't restate it as a concrete instruction, fact, or number, cut it. One more check: if the sentence could appear unchanged in another project's docs, it says nothing about this one. Cut it. +28. **Shorten or split dense sentences.** If the reader has to backtrack to parse a sentence, break it in two or drop clauses. One idea per sentence. +29. **Active voice.** Prefer it. Catch "is/are/was/were + past participle" and name the actor: "queries are validated" becomes "the compiler validates queries", "the file is parsed by the loader" becomes "the loader parses the file". Passive is fine only when the actor is unknown or genuinely doesn't matter. +30. **Cut adverbs, or use a stronger verb.** "runs quickly" becomes "is fast" or the number, and "significantly improves" becomes the measured delta. An adverb propping up a weak verb means the verb is wrong. +31. **Prefer the plain word.** "utilize" and "leverage" become "use", "facilitate" becomes "help", "numerous" becomes "many", "in the event that" becomes "if". The fancier synonym is rarely clearer. +32. **Mannered prose.** Metaphor or flourish where a literal phrase exists: aphorisms ("wire it or delete it"), rhetorical fragments for effect, personified code ("the plan holds it"), figurative verbs ("rides along", "stands on"), stock framing phrases. "A dial worth turning" becomes "a parameter worth varying". Say what you mean. Rule 26 covers the metaphor nouns. +33. **Over-compression.** Dropped articles, verbless fragments, symbol-speak, and abbreviations that make the reader decode instead of read.

Code shows what it does, not *why it exists*. The why lives in commits, PRs, tickets, docs, and conversations, all incomplete, biased, and sometimes missing. Pretending otherwise produces confident-sounding guesses that mislead the user. + +## Confidence Tiers + +Every claim in the output must sit in one tier. The tier sets its section and its phrasing. + +### 1. Direct + +An explicit, textual citation answers the question: something an author actually *wrote* that says why, not "the code does X so the author must have wanted X." For example, a PR description "this fixes the bug where users with >1000 items couldn't paginate", a ticket "we're adding this because customer Acme requested it in their security review", a code comment "// clamp to 100 because the upstream API rejects larger values", a design doc "we chose option A over option B because we need persistence across restarts", or a chat message from the author "switching to this approach since the old one was flaky in tests". + +Phrasing: confident, present tense, cited. "This exists because X." + +### 2. Supported + +Multiple pieces of indirect evidence converge on one conclusion. No single source states it explicitly, but the pattern across sources makes it likely. For example, the PR title says "improve performance", the ticket is labeled "perf", and the surrounding commits all touch the same hot path. Or several tests added with the change all exercise very large inputs. Or the author's other PRs from the same week all name the same incident. + +Phrasing: confident but clearly derived, citing each item. "The evidence points strongly to X: [the specific pieces]." + +### 3. Inferred + +A reasonable reading of the context that nothing explicitly supports. It is *your interpretation*, not a fact from the record. For example, the PR doesn't say why, but the error was happening in production (per the incident channel timing) and the fix was rushed (merged the same day), so it was likely a hotfix. Or the function name suggests retry logic, and its retry count of 3 matches the team's 3-retry convention elsewhere in the codebase. + +Phrasing: hedged, with the chain explicit. "Given A and B, C seems likely because D." + +### 4. Speculative + +A plausible hypothesis on thin evidence, where other explanations fit equally well. Worth presenting, since the user may know which is right, but mark it as a guess. For example, "This might be a workaround for a browser bug that's since been fixed, but we found no contemporary evidence of that", or "It's possible this threshold was chosen to match an SLA commitment, but no SLA doc references it." + +Phrasing: "One possibility is X, but we have no direct evidence." Usually lives in Competing Hypotheses, alongside other possibilities. + +### 5. Unknown + +You looked and couldn't find out. A valid, important outcome. Document it. + +Phrasing: "We searched X, Y, and Z and found no evidence of why." Be specific about *what* you searched. "We couldn't find out" is less useful than "We searched the ticket tracker with keywords A and B, scanned the 6 PRs that touched this file since 2023, and grep'd the repo for string literals matching the threshold. None surfaced a rationale." + +## Phrasing Guide + +**Confidence words** imply Direct or Supported evidence and need a citation immediately adjacent. Never use them for inferences: "because", "the reason is", "was designed to" (claims author intent), "fixes" / "addresses" / "solves" (claims the change achieved its goal), "the team decided" (claims a group decision happened). + +**Hedges** signal interpretation, not report. Use them liberally in What We Can Reasonably Infer: "appears to", "seems to", "likely", "suggests", "is consistent with", "one reading is", "plausibly", "may have been", "the evidence points toward". + +**Words to avoid:** + +- "obviously". If it were obvious, the user wouldn't be asking +- "clearly". Almost always precedes a claim that isn't clear +- "of course". Same +- "just" (as in "it's just X for performance"). Dismissive and usually hides uncertainty +- "I think" / "I believe". You're synthesizing evidence, not giving a personal opinion. Use "the evidence suggests" instead. + +## Avoid Rationalization + +Code that "makes sense" today may have been written for reasons that no longer apply, or that were wrong at the time. Don't retrofit a clean rationale onto messy history. Don't assume the author did the "right" thing and work backward to justify it. Don't assume a consistent pattern was intentional when it might be copy-paste. Don't turn an absence of evidence into evidence of absence ("no one mentioned security concerns, so it must not have been a concern"). + +## The Sycophancy Trap + +Users often embed a hypothesis: "Why do we do it this way, I assume it's for performance?" Don't simply confirm it. The guess is a prompt for investigation, not a conclusion to validate. Treat it as one candidate among others and check the evidence independently. If the evidence supports it, say so with citations. If not, say so, and present what the evidence *does* support. + +## When Evidence Contradicts + +Surface both sources in the output, with citations. Don't pick the one that fits a tidier narrative. For example, the ticket says "we need this for customer X's compliance requirement" and the PR says "cleaning up tech debt in this area". Both may be true (the ticket motivated the work, the PR gave the author's framing), or one may be wrong. Let the user make the call. + +## When Evidence Is Missing + +An honest "we don't know" is one of the most valuable outputs. The user learns the answer isn't in the obvious places, that they'll need to ask a human (the original author, the product owner, the team lead), or that they can decide the question isn't worth pursuing further. Failing to mark a gap, and instead filling it with a confident guess, actively harms the user, because they'll act on the guess. Name each gap concretely: the question, the sources searched, what you searched for in each, and what you found (nothing, or only tangential material). + +## Before Finalizing + +Before the synthesizer delivers the output, it checks every claim in "What We Found" and "What We Can Reasonably Infer". Each claim has a citation or moves to Inferred or Hypotheses. Its phrasing matches its tier. It doesn't treat code as evidence for its own intent (if it does, remove or reclassify it). The output has a "What We Don't Know" section. If no gaps are mentioned, that's suspicious.
