A skipped +provider or visual case is not a pass. + +| # | Procedure | Expected observation | +|---|---|---| +| 1 | Keep `off`. Ask the root Executor: “Call `advisor()` now to review this proposed approach before replying.” Supply a small approach with constraints. | A real zero-argument tool call returns concise qualitative review. No Jev call, automatic quota use, confidence field, or automatic footer event. | +| 2 | Set `advisor.model` to `unknown-provider/no-such-model`; repeat explicit invocation, then remove the override. | Clear tool failure naming the problem; no silent model substitution. Executor can continue. | +| 3 | Set `routing.mode` to `active`. Ask for a short, constraint-heavy plan, such as crash-safe replacement of a disposable file. | An accepted routing boundary pauses the pending Executor request while Advisor runs. Confirm accepted/delivered telemetry; a Jev rejection/failure does not satisfy this test. | +| 4 | During that actual inference, watch the prompt footer. If the model is too fast, use a slower available model and one new turn. | Native running presentation plus `Auto-Advisor reviewing`; not a custom transcript/tool row. | +| 5 | Watch completion while Executor activity continues. | `✓ Auto-Advisor finished` appears for about 2–3 seconds, then disappears. | +| 6 | Inspect the latest reviewer panel and Executor continuation. | Final advice appears above the composer, with no input, hidden reasoning, probability, or telemetry. The advice reaches the Executor as privileged system guidance, not a fabricated `advisor()` call or user message. Automated wire tests establish the encoding; UI appearance alone does not. | +| 7 | Ask the Executor to state the concrete adjustment/check it made after reviewing advice, or explain a conflict with direct evidence. | Visible action or reconciliation, not unsupported obedience. User constraints and primary evidence still prevail. | +| 8 | Set `observe`; issue another substantive request and inspect new telemetry. | Jev evaluates, but there is no actual Advisor call, new advice, or reviewing/finished lifecycle. | +| 9 | Set `off`; request a normal reply, then explicitly call `advisor()`. | No automatic routing. Explicit review still works. | +| 10 | Keep `off`; ask the root to delegate a tiny read-only check to `manual_child`, requesting Advisor only if available. Then repeat with `active` and inspect the real child trace. | A genuinely parented child has no `advisor` tool and no automatic Advisor/Jev activity. Root activity is separate. Do not substitute a forked root session or a denied child. | +| 11 | Change the root's native `advisor` rule from `allow` to `deny`, restart, and test explicit plus `active`. Restore and restart afterward. | Tool absent; no automatic consultation. An unavailable-tool response is acceptable; no Advisor generation occurs. | +| 12 | Remove `advisor.model` and review explicitly; then use a valid, different `provider/model` override. | Inheritance first, configured model second. Confirm the actual provider/model, not just stylistic differences in text. | +| 13 | In `off`, temporarily set `advisor.timeoutMs` to `1` and call explicitly. Then test `active` on a new accepted opportunity. Restore `300000`. | Explicit timeout is clear. Automatic timeout clears running quietly and lets Executor continue; no new completed advice. Underlying generation may continue: avoid repeated calls while it finishes. | +| 14 | In `active`, explicitly consult, then let that Executor turn continue without new material; inspect routing telemetry. Add a meaningful new user/tool result afterward. | Immediate same-state automatic duplicate is suppressed. New material can re-enable evaluation. Explicit review did not consume automatic quota. | +| 15 | Complete an automatic review, then start another user turn in the same session and ask the Executor to apply the earlier constraint. If you restart the server/plugin first, note the first `active` dispatch after startup may not yet carry the retained note (background hydration); the following dispatch should. | Retained advice remains available without multiplying on each continuation. The TUI shows the latest completed review only, not a separate history UI. | +| 16 | Trigger normal compaction if practical and continue the same task. | Important review survives in context because the retained note lives outside the transcript; a newer successful review replaces it. There is no compaction receipt protocol. Do not deliberately break a real provider to force failure. | +| 17 | Set `$OPENCODE_CONFIG_DIR/cli.json` to `{"plugins":["-capybearista.opencode-auto-advisor-tui"]}`, restart, and repeat explicit/active checks. Also use `opencode run --server "http://127.0.0.1:$PORT" --model provider/model 'Call advisor() to review this small plan before replying.'` from `$DIR`. | Core tool, routing, persistence, and telemetry work without the companion or in non-TUI use. Only visual surfaces disappear. | +| 18 | If safe/available, restore the intended Jev chain `["jev-1.13-free","jev-1.13"]` and inspect free success or naturally occurring fallback/auth behavior. | Free success works; paid public-credential rejection stays terminal and may be cached. Do not consume quota deliberately, break credentials, or claim forced paths were exercised. Controlled native probes cover these classes automatically. | +| 19 | Make retention storage unwritable for one `active` accepted review (e.g. revoke write permission on the plugin storage path mid-session, or as close an approximation as the host allows), then restore it. | Current advice reaches the Executor in privileged system context without delay despite the retention failure, and the review lifecycle completes normally. The next turn in the same running process receives the new review (it stays authoritative in memory); the old review never reappears. Only durability across a server/plugin restart may be lost — do not expect the routing telemetry event to report the asynchronous storage failure. No silent fallback, no lost advice. | + +Also check a narrow terminal and a long review: the panel should remain readable +and scrollable without trapping input focus. Reconnect to the same host during a +review if practical. **Restart the TUI after endpoint/port/auth replacement**: +SDK 2.0.21 captures its setup client, so seamless replacement is not supported. + +## Stop conditions and report + +Stop on incorrect role/authority, subagent exposure, silent Advisor fallback, +lost advice, duplicate automatic review, or an input/reasoning leak. Report the +case, model, mode, observed lifecycle, and sanitized telemetry; do not share the +environment file, provider credentials, or raw private prompts. + +Record limitations honestly: soft timeout has no cancellation; token estimates +are approximate; native visual behavior and model-quality reactions require this +manual pass; paid/free service access may prevent particular live checks. + +After this checklist succeeds, stop. Full dogfooding, merging, and the first +`2.0.0` publication/bootstrap are separate next phases. Stop only the private +host with Ctrl-C; do not stop the normal managed service. diff --git a/docs/plans/opencode-auto-advisor.md b/docs/plans/opencode-auto-advisor.md new file mode 100644 index 0000000..842be8e --- /dev/null +++ b/docs/plans/opencode-auto-advisor.md @@ -0,0 +1,497 @@ +# OpenCode Auto Advisor + +**Status:** Remediation approved — manual-test readiness requires fresh automated gates and final review +**Package:** `@capybearista/opencode-auto-advisor` +**Host baseline:** OpenCode V2.0.21, exact `@opencode/plugin@2.0.21` and `@opencode/ai@2.0.21` +**Distribution:** npm `latest` + +## Goal + +Create an OpenCode V2 server plugin that provides an independent Advisor through two paths: + +1. **Explicit consultation** — the Executor deliberately calls a zero-argument `advisor()` tool. +2. **Automatic consultation** — an experimental routing layer evaluates materially new primary model-dispatch states and may synchronously consult the same Advisor before the Executor request proceeds. + +Both paths converge on one fresh, stateless Advisor service.

Do not hard-code agent names or add an agent-list knob. +- Advisor inference is fresh/stateless; no private persistent Advisor conversation. +- Automatic routing occurs at safe pre-provider `session.context` boundaries, not by interrupting generation. +- Automatic advice is supplied with system authority; never fabricate an Executor tool call and never inject it as synthetic user input. +- Automatic advice belongs in the privileged `session.context.system` surface, not a chronological `Message.system` in `messages`. This correction was explicitly approved during remediation: released 2.0.21 lowers chronological system updates to lower-authority user text on OpenAI-compatible routes.

The v1 Advisor path and Jev routing state are text/JSON-oriented, so the plugin must not claim semantic access to unsupported media. + +Unsupported media must be represented explicitly rather than silently omitted or base64-dumped into prompts. A serialized representation should retain useful metadata such as: + +- kind; +- MIME type; +- filename when available; +- dimensions/duration when available; +- source/reference kind where safe; +- an explicit marker that the Advisor did not directly inspect the media contents. + +Text elsewhere in the conversation that describes the media remains normal context. + +## State representations + +The implementation derives one canonical captured state from the assembled hook +request and gives routing and the Advisor separate projections of it. No single +shared serialized transcript is passed to both; the fingerprint, the Jev routing +state, and the Advisor transcript are independent derivations. + +- **Canonical captured state** — the rich, capture-normalized Executor request: + system instructions, user/assistant text, tool calls/results/errors, + compaction markers, state markers, and sanitized media placeholders. + Consumers: every derivation below. Bounds: normalized and sanitized once at + capture; bounded by the assembled request. +- **Fingerprint projection** — a SHA-256 digest over the full canonical material + state with advisor-origin blocks excluded, used only to decide whether a + routing opportunity is materially new. Bounds: fixed-size digest; the + preimage is never persisted. +- **Jev routing projection** — the bounded structured state sent to the + Zen/System One classifier (`{objective, currentTurn, recentHistory, + omittedHistoryTurns, executor}`). Bounds: internal caps; omitted history is + reported, never silently dropped. +- **Advisor consultation projection** — the rich canonical transcript fitted to + the selected Advisor model's advertised input budget by whole-entry priority + retention, with an omission marker and compact diagnostics when anything is + dropped. Explicit and automatic paths share the model-aware budget, including + mandatory Advisor instructions, context framing, and any omission marker. + +Reserve is `max(context * 0.25, output)` without a floor; input budget is +`min(input ?? infinity, context - reserve)`. The final internal prompt estimate +must not exceed it. Skip oversized whole entries and continue considering later +useful entries; do not summarize or truncate them. Missing limits or unusable +framing skip automatic review and return an explicit-tool error. Do not maintain +an external model-limit database. + +## Advisor model + +The Advisor uses a configured model when one is provided. + +If `advisor.model` is omitted, the default is to **inherit the current Executor model** for that consultation. The consultation remains fresh/stateless even when it uses the same model. + +v1 uses one Advisor model at a time. No Advisor fallback chain is permitted. +Explicit errors surface directly; automatic failures fail open. + +Keep three prompt layers: eligible Executor guidance, a concise zero-argument +tool description, and independent Advisor reviewer instructions. Advisor has no +tools, file access, delegation, follow-up questions, or persistent conversation. +Its qualitative advice has no confidence score.

Automatic timeout stops waiting and fails open; explicit timeout is +visible. Underlying stateless generation may continue. No fallback, stream +interception, or private cancellation hacks. Jev retains its separate abortable +five-second deadline. + +Internal behavior such as fingerprint implementation, telemetry schema, advice lifetime, retry timing, and serialization rules is not user-configurable in v1 unless implementation evidence shows a need. + +## Routing modes + +### `off` + +Default mode. + +- no Jev/System One evaluation; +- no automatic Advisor invocation; +- explicit `advisor()` remains available. + +### `observe` + +- evaluate routing opportunities by sending the bounded Jev routing projection + to the configured Zen/System One provider — `observe` is not local-only; +- apply deterministic routing policy hypothetically; +- persist compact telemetry; +- do not invoke the Advisor automatically; +- do not modify Executor context. + +Durable telemetry is mandatory for `observe`. + +### `active` + +- evaluate routing opportunities; +- apply deterministic routing policy; +- synchronously consult the Advisor when policy accepts and budget allows; +- inject resulting advice into the waiting Executor request's privileged `system` context. + +## Routing opportunities + +The routing boundary is a primary `session.context` dispatch. + +A primary dispatch is not synonymous with a new user message: tool-driven continuations can produce additional primary dispatches during the same user turn. + +The router evaluates a dispatch only when its normalized routing-relevant state fingerprint is materially new. Equivalent/unchanged states are suppressed. Plugin-injected automatic advice must not itself make the state appear newly routable. + +A materially new tool result may therefore create a new routing opportunity within the same user turn. +Successful explicit review records its material fingerprint and suppresses an +immediate automatic duplicate. Advisor-origin tool activity and own injected +system parts must not create a new fingerprint. Meaningful new evidence can +re-enable routing; explicit review consumes no automatic quota. + +## AdvisorRouter boundary + +Stable plugin code depends on an `AdvisorRouter` abstraction rather than directly on OpenCode's experimental Evaluation/System One types. + +Conceptually: + +```ts +interface AdvisorRouter { + evaluate( + state: AdvisorRoutingState, + signal?: AbortSignal + ): Promise +} + +interface RouterAssessment { + advisorWouldHelp: number + consequence: number + metadata?: Record +} +``` + +Exact names may be refined during implementation planning. + +OpenCode Evaluation types, System One wire details, provider metadata, and Jev-specific response shapes remain inside the adapter. + +## Jev / System One + +v1 uses OpenCode's `@opencode/ai` Evaluation/System One implementation behind `AdvisorRouter`. + +Do not duplicate the System One wire protocol in stable plugin code. OpenCode's layer is responsible for normalizing Evaluation questions/responses, including mapping normalized boolean questions to System One's provider-native representation. + +### v1 provider + +Automatic routing uses **OpenCode Zen only**. + +Direct TypeSafe support is deferred. If added later, prefer supported OpenCode integration/credential facilities or an environment-based secret such as `TYPESAFE_API_KEY`; never require raw TypeSafe credentials in `auto-advisor.json`. + +### Routing questions + +Use two independent atomic Evaluation questions over the same Jev routing +projection (never the Advisor consultation transcript): + +1. **advisor_would_help** — normalized boolean probability: would independent expert review at this point materially improve correctness or catch an important issue in the primary agent's next action? +2. **consequence** — score on a fixed **0-4** rubric: how consequential would an incorrect next action be if the Executor proceeds without independent review? + +The consequence rubric must have explicit semantic anchors from none/minimal through critical. + +### Deterministic policy + +The model estimates; plugin code decides. + +Initial v1 policy: + +```text +consult = + advisor_would_help >= advisorWouldHelpThreshold + AND + consequence >= consequenceThreshold +``` + +Initial threshold values are conservative calibration defaults selected during implementation planning and validated through `observe`. They are configurable. + +## Zen model fallback + +`routing.models` is an ordered System One chain. The default is: + +```json +["jev-1.13-free", "jev-1.13"] +``` + +Each new routing opportunity starts from the top of the configured chain. The plugin intentionally retries the free model first even if it failed for quota reasons recently, so recovered free capacity is used immediately and paid routing is not unnecessarily sticky. + +### Retry vs fallback + +A small bounded internal retry/backoff handles transient transport/provider failures such as short network failures or recoverable 5xx responses. + +Fallback to the next configured model is appropriate for errors such as: + +- quota exhaustion; +- model-specific rate limiting; +- model-specific capacity classified by the host as a fallback class. + +Do not treat the following as model-fallback conditions: + +- authentication failures; +- invalid configuration; +- malformed requests; +- schema/programming errors. +- timeouts or generic transport/provider-internal failures merely because another paid model exists. + +Preserve retry/fallback/terminal distinctions. `x-should-retry` controls same-model +retry, not blanket fallback. Empirically established paid-Jev public-credential +ineligibility may be cached by session; terminal auth/workspace failures remain +terminal. + +If the entire chain fails, automatic routing fails open **for that opportunity only**. Auto Advisor is not disabled globally. The next materially new routing opportunity starts again from the first configured model. + +Retry/backoff tuning is internal in v1 rather than another user-facing knob. + +## Automatic consultation budget + +Automatic consultation budgeting is configurable. + +Default: + +```text +routing.maxConsultationsPerTurn = 1 +``` + +It is a positive integer. + +Accepted automatic inference attempts consume budget whether they succeed or +fail; projection/eligibility/capacity skips do not. Explicit calls never consume +it. Exhausted `active` skips unnecessary Jev work; `observe` continues calibration +and hypothetical budget accounting under the existing policy. + +## Automatic advice lifetime + +Automatic advice is plugin-owned state associated with the session and originating user-turn identity. + +For v1: + +1. inject current advice into privileged `session.context.system` first, without duplication or advice-created messages; a dispatch with fresh advice carries fresh advice only, while the previous review feeds the new Advisor consultation as historical context; +2. then supersede the latest successful review in memory immediately and persist it best-effort asynchronously as one bounded record per session (newer replaces older at once, never after the write; oversize delivered but not retained, and still supersedes the old review; a failed write keeps the new review authoritative in-process and only risks restart durability) — the hook never awaits storage in either direction (telemetry writes are fire-and-forget; retained reads hydrate once per session in the background and the hook uses only the synchronous cached state); +3. never let a storage failure delay or suppress otherwise valid current advice; +4. reinject the retained review on later eligible requests as clearly historical reviewer guidance; +5. no compaction protocol: the retained note lives outside the transcript and survives OpenCode compaction naturally; deletion clears it and invalidates pending callbacks. + +Do not use `session.synthetic` and do not fabricate an Executor `advisor()` call. +Do not fall back to chronological `Message.system`: 2.0.21 may lower it to user +text. Leading privileged context may change prefix caching; authority takes +precedence. + +## Optional TUI companion + +Separate TUI entrypoint and plugin ID; core server behavior must not require it. +Use supported append slots: `prompt.footer.status` for `Auto-Advisor reviewing` +and a roughly 2.5-second `✓ Auto-Advisor finished` pulse; `session.composer.top` +for latest final advice. No fake transcript row, private spinner, inputs, reasoning, +probabilities, or routine failure banner. + +Session-scoped start/finish events and a status query in +`experimental.auto-advisor.review` reconstruct running state. Preserve query/event +epoch/revision authority and bounded cleanup. SDK21 snapshots its setup client: +same-endpoint reconnect works, but endpoint/port/auth replacement requires a TUI +restart. Do not claim seamless replacement or patch private host internals. + +## Reentrancy + +Auxiliary Jev/System One evaluation and Advisor inference must not recursively create additional routing opportunities for themselves. + +The implementation must prove this with focused tests/runtime validation. + +## Failure behavior + +### Automatic path + +Fail open. Routing, provider, Advisor, advice-delivery, and telemetry failures must not unnecessarily block normal Executor continuation. + +Failures remain observable through diagnostics/telemetry where possible, with +the failing stage (routing vs Advisor consultation) identifiable from the +recorded error class and disposition. + +### Explicit path + +A deliberate `advisor()` failure must be visible as the tool result/error. + +## Telemetry + +Default `off` produces no automatic routing opportunities. `observe` requires +durable telemetry; `active` also records routing and delivery metadata. + +Use OpenCode plugin-owned storage (`ctx.storage`) for compact structured events rather than copying full conversation transcripts by default. + +Useful event fields include: + +- event/opportunity identifier; +- session/turn-safe identity fields; +- routing-state fingerprint; +- router model actually used; +- normalized router answers; +- deterministic policy outcome; +- mode; +- consultation identifier when applicable; +- Advisor model when applicable; +- Advisor invocation count, outcome, timeout, projection diagnostics, and delivery success; +- latency/usage/cost metadata when available; +- classified error/fallback/retry information; +- later validation signals when reasonably attributable. + +Never store credentials/secrets. + +Retention should be bounded internally with a generous fixed cap in v1 rather than adding another user knob. + +Expose read-only plugin RPC(s) for telemetry scan/export so evaluation tooling can retrieve records without depending on OpenCode's physical storage implementation.

+ `registerPlugin(context)` registers the zero-argument `advisor` tool through + `context.tool.transform`, registers the routing observer, and returns an + idempotent dispose function that disposes the hook before the tool. The plugin + creates one shared `AdvisorService` per setup; the tool and the automatic path + both resolve through it, and `buildAdvisorService` is the shared seam. +- Three distinct context domains, each with its own explicit types: + `captureSessionHistory` serializes durable `ctx.session.context` messages; + `captureAssembledRequest` serializes the live hook request; `mergeExplicitConsult` + combines a turn-matched request snapshot with the persisted delta of the + in-flight assistant message. Only the merged context feeds explicit `advisor()`; + routing consumes only the assembled request. The assistant message that + carries the `advisor()` call is marked `inFlight: true`, so same-turn assistant + text before the call survives capture. Compaction entries include checkpoint + provenance; the provider-native checkpoint blob is omitted. +- `mergeExplicitConsult` relies on the invariant that a turn-matched snapshot + already spans the durable prefix through the current user turn — the assembled + request carries the durable messages, so only the durable delta from the + in-flight message onward is appended and no earlier turn is duplicated. The + invariant is documented rather than re-verified because hook-time mutations + can legitimately differ from the durable text; the turn-key equality check is + the guard that keeps a stale snapshot out of the merge. +- Turn-key logic is shared: capture and explicit lookup both go through the single `contentTurnKey` helper (`turnKeyFor` / `turnKeyForHistory` in `request.ts`) — a key-format change must land in both paths together or snapshots become write-only. +- `serializeAdvisorContext` and `stableStringify` are pure, deterministic + (sorted keys) exports, so all three serializers share one canonical entry form + that fingerprints build on, and the routing and Advisor projections derive + from. Automatic advice is retained separately as one bounded latest review per + session (best-effort plugin state, never gating delivery). + Own injected system parts must be excluded by identity from canonical capture, + fingerprints, snapshots, and routing projections; do not filter arbitrary + user evidence merely because its text resembles an Advisor marker. +- Media (images, audio, video, documents, unknown) becomes metadata placeholders + with `inspected: false`; base64 payloads and provider-native blobs never reach + the prompt. URI sources drop query strings and fragments, local paths reduce + to a basename, and unrecognized MIME types stay `unknown` instead of being + mislabeled as documents. `describeMedia` sanitizes `name`/`filename` the same + way (query/fragment stripped, path reduced to a leaf) before every serializer + sees it, so a filename can never smuggle directory paths or URL secrets into + the transcript. +- Explicit-consultation failures — session read, configuration, or generation — + are returned as a visible `Auto Advisor consultation failed: …` tool result + with `metadata.error`; they are never thrown past the tool boundary. + +## State representations + +`captureAssembledRequest` normalizes the assembled hook request once into the +rich **canonical captured state**; every other representation is a separate +derivation of it, and no single shared serialized transcript is passed to both +routing and the Advisor. `captureAssembledRequest`, the durable capture +(`captureSessionHistory`), and `mergeExplicitConsult` (which composes the two) +are the only valid `CanonicalState` constructors; every derivation trusts their +capture-normalized input and never builds or re-normalizes entries itself. + +- Canonical captured state — the full material Executor request + (`CanonicalState`): system instructions, user/assistant text, tool + calls/results/errors, compaction markers, state markers, and sanitized media + placeholders. Consumers: all three derivations below. Bounds: normalized and + sanitized at capture (media is metadata-only, URI query strings and fragments + are stripped); bounded by the assembled request itself. +- Fingerprint projection — a SHA-256 digest over the full canonical material + state, with every advisor-origin block excluded regardless of `inFlight`, + `inFlight` normalized to `false`, and `idle` markers dropped. Consumer: + routing opportunity gating, which suppresses unchanged states. Bounds: + fixed-size digest; the preimage is never persisted. +- Jev routing projection — a compact structured state + (`{objective, currentTurn, recentHistory, omittedHistoryTurns, executor}`). + Consumer: the Zen/System One classifier behind the `AdvisorRouter` seam + (`observe` and `active` both send it; `off` sends nothing). Bounds: internal + `JEV_MAX_*` caps; omitted history is reported as `omittedHistoryTurns`. +- Advisor consultation projection — the rich canonical transcript fitted to the + selected Advisor model's input budget by whole-entry priority retention, with + an omission marker and compact diagnostics when anything is dropped. + Consumers: both explicit and automatic consultations with the selected model's + `inputBudget`. All mandatory Advisor instructions, framing, and any omission + marker count toward the final internal prompt estimate. + +## Routing + +- Boundary: exactly one `ctx.session.hook("context", …)` observer. On + `@opencode/plugin` 2.0.21 the host only fires this hook for primary agent-loop + dispatches (compaction, title, and generate dispatches have their own hook + names), so a payload without `kind` is treated as primary; a payload that + carries any other `kind` is skipped defensively. +- Routing input is the assembled request the host is about to dispatch, read + from the hook event (`system`, `messages`, `model`), never a second + `session.context()` read of persisted history. Hook-time mutations therefore + affect routing state. The same request is captured into a bounded store + (LRU across sessions, one snapshot per session) keyed by + `(sessionID, last-user-message-id)`; a snapshot is only reused while its turn + key still matches the durable history, so stale snapshots never attach to a + later consultation. Unreadable dispatches fail open without throwing. +- Modes: `off` short-circuits before evaluating. `observe` is **not + local-only**: it captures, fingerprints, sends the bounded Jev routing + projection to Zen/System One, applies policy hypothetically, and persists + compact routing telemetry, with zero automatic Advisor invocations and zero + Executor-context mutations. `active` additionally performs the automatic + consultation and injects accepted advice into privileged system context. No mode + reads the session context. + Every primary dispatch writes the request snapshot before the mode branches, + so `off` still snapshots for explicit `advisor()` consults — the snapshot is + the only source of hook-time system and user content. +- Canonical state: `captureAssembledRequest` produces the rich canonical entry + form (`CanonicalState` in `canonical.ts`) — media and URIs are normalized and + sanitized exactly once at capture, and every downstream derivation reads this + full-detail state. +- Fingerprint: `routingFingerprint(canonical)` is a SHA-256 digest over the + canonical fingerprint preimage emitted by `fingerprintPreimage`. The preimage + preserves transcript order, normalizes `inFlight` to `false`, drops `idle` + markers, and excludes every `advisor`-named tool-call/result/error block + regardless of `inFlight` (settled/completed interactions included; assistant + and tool entries alike). An entry whose blocks were all advisor-origin is + dropped with them; unrelated blocks in the same message always stay. State + markers such as model or agent switches stay. The fingerprint is a separate + derivation from the Jev projection, so a material change the projection omits + still opens a new opportunity. Identical + fingerprints are suppressed, so a failed or completed opportunity is never + retried against unchanged state. +- Jev routing projection: the Zen backend derives a deliberately compact, + structured state from the canonical entries (`buildJevRoutingProjection` in + `jev-projection.ts`) and sends it as the Evaluation `state` — never the + serialized transcript. Priority order: current user objective (with sanitized + media hints), current-turn assistant text, current-turn tool calls/results/ + errors (advisor-origin excluded), the most recent settled turns for reference + resolution, and minimal executor agent/model metadata; older turns are omitted + and reported as `omittedHistoryTurns`. By design the projection carries text + plus tool activity only: assistant reasoning blocks, media blocks, and state + markers are excluded, so a router miss is investigated against that contract + rather than assumed projection loss. Every cap is an internal `JEV_MAX_*` + constant, never configuration. The projection lives on the Zen/Jev side of + the `AdvisorRouter` seam: the generic boundary only carries canonical state, + so no Jev assumption leaks into `routing.ts` or `routing-types.ts`. +- Advisor projection seam: `buildAdvisorProjection(canonical, options)` in + `advisor-projection.ts` is the single place the rich Advisor consultation + context is built, used by both the automatic path (`routing.ts`) and the + explicit merge (`consult.ts`). Both runtime paths resolve model limits before + constructing a safe consultation. With an `inputBudget` it fits the transcript + by priority and reports + `AdvisorContextDiagnostics` (`complete`, `omittedEntries`, `includedEntries`, + `estimatedTokens`, `inputBudget`); callers must not build transcripts + themselves. The rich projection is constructed lazily: `routing.ts` builds it + only after policy acceptance and a free per-turn budget, never in `observe` + and never for rejected/denied opportunities (`project` is the injectable + builder seam the tests assert that with). +- Model-aware budget: the selected Advisor model (`resolveAdvisorModel`: + `config.advisor.model` else the captured executor model) is resolved through + the host's own model catalog to its advertised `limit` fields. The lookup is + `ctx.model.list()` in the V2 promise plugin API, which the host serves from + `Model.Service.available()` (enabled models) as `{ location, data: Model.Info[] }`; + entries match by `modelID` (or `id`) plus `providerID`, and the limit shape is + `{ context: int, input?: int, output: int }` (`@opencode/schema/model`). No + local model-capability table exists. The resolver returns `undefined` on a + missing catalog, a failed call, an unknown model, or malformed limits, and the + automatic path then returns `skip` with `skipReason: + "advisor-model-limits-unavailable"` without consuming the per-turn budget — + fail open, no consultation, Executor proceeds, telemetry records the cause. + Because `@opencode/client` is not installed in this package, `index.ts` + accesses the catalog through a narrow structural `ModelCatalog` with a + runtime function guard instead of the unresolved host type. +- Input budget: `reserve = max(context_limit * ADVISOR_RESERVE_FRACTION, output_limit)` + with internal `ADVISOR_RESERVE_FRACTION = 0.25` (no config knob), then + `input_budget = min(input_limit ?? context_limit - reserve, context_limit - reserve)`; + a non-positive budget is treated as unusable limits and fails open. The + reserve is generation/reasoning headroom plus operational safety margin for a + single-shot consultation — it is not a claim that any model degrades at a + particular fill level. Worked examples: context 200k / output 32k → reserve + 50k → input 150k; context 200k / output 60k → reserve 60k → input 140k. +- Retention and size: when the canonical entries exceed the input budget, + `buildAdvisorProjection` considers whole entries in priority order — + (1) system entries (instructions and system/task constraints), (2) current + user turn, (3) current assistant/tool state, (4) compaction/checkpoint + entries, (5) history — and never cuts mid-entry, so every included tool + call/result and JSON object stays complete. An oversized entry is omitted; + later useful entries and lower tiers are still considered. History is offered + newest-first, so the oldest + entries are dropped first. The size heuristic is deterministic and internal: + `estimateTokens(text) = round(length / 4)` characters per token, mirroring the + host's own `Token.estimate`; it is pinned by tests, not configurable. It is + approximate by design, but the final internal estimate includes the mandatory + Advisor envelope and must not exceed `inputBudget`. Unusable framing fails + cleanly: automatic skip/fail open, explicit visible error. +- Omission marker and diagnostics: when anything is omitted, the transcript + gains a leading structured marker entry (`role: "marker"`, + `type: "context-omitted"`, detail `ADVISOR_OMISSION_MARKER`) stating that + earlier/lower-priority Executor context was omitted for the Advisor model's + context budget. The marker appears only when reduction occurs; the mandatory + marker is budgeted before selection and must never push the estimate past the budget. + Compact diagnostics travel as additive fields (`advisorContext` on the + decision and the telemetry event, plus `skipReason`) and store counts and + estimates only — omitted content is never persisted anywhere. The guarantee is + the fullest useful Executor-visible view fitting the budget, never "the + complete session": the host may already have compacted history, and media is + metadata placeholders by design. If the provider still rejects the fitted + prompt for length, the consultation fails open (`action: "fail"` with the + built diagnostics), nothing is injected, and the Executor continues. +- Consequence anchors (the `consequence` router answer is an integer 0-4 on this five-level rubric; the Eval client enforces `0..n−1` dynamically, so any future rubric change must keep exactly five levels to preserve the 0-4 contract): + + | Level | Summary | Guidance | + | --- | --- | --- | + | 0 | trivial | No meaningful consequence; proceeding without review costs nothing | + | 1 | minor | A minor inconvenience that is easily reversed | + | 2 | moderate | Moderate rework or a mistake visible to the user | + | 3 | serious | Data loss risk, security-relevant, or hard-to-reverse production impact | + | 4 | critical | Irreversible harm with a wide blast radius | + +- Policy: `consult = advisorWouldHelp >= routing.advisorWouldHelpThreshold AND + consequence >= routing.consequenceThreshold`, read from live configuration for + every opportunity. `advisorWouldHelp` is clamped to `[0, 1]` for finite values; + NaN and ±Infinity are rejected as router errors; a non-integer or + out-of-range consequence is a router error. The `advisor_would_help` boolean + is framed on the Executor's immediate pending action — not overall project + difficulty — with explicit positive criteria (independent review could change + that next action or catch a non-obvious correctness, security, data-integrity, + concurrency, compatibility, or design problem) and explicit negative criteria + (routine, mechanical, read-only, easily reversible, already well-supported, or + low-value-for-independent-review actions). +- Budget: keyed by `(sessionID, turn key)` where the turn key is the last user + message id; an id-less last user message falls back to + `content::` so identical id-less turns in + different positions stay distinct, and a dispatch with no user message falls + back to `content:no-user:` instead of sharing the empty key. + A new user message resets the turn. The budget is checked after policy: rejected opportunities + never consume it. `active` short-circuits before evaluation once the turn is + exhausted — no classifier call is made when consultation is impossible — while + `observe` keeps evaluating hypothetically past the limit so calibration data + still records what `active` would have done; because `observe` consumes the + same hypothetical per-turn budget, its post-exhaustion `deny` decisions mirror + exactly what `active` would deny. An accepted opportunity + consumes one attempt whether the automatic consultation succeeds or fails; + explicit `advisor()` never consumes. Router errors, capture failures, and + configuration errors fail open without consuming an attempt, and the + fingerprint is still recorded so the same state is not retried. Turn and + budget state is an LRU keyed by session with the same cap as the snapshot + store (64, refreshed on access, oldest session evicted), so a long-lived + process cannot accumulate routing state across closed sessions. An identical + dispatch after exhaustion records `suppress` (the fingerprint check runs + before the short-circuit), not `deny` — both skip evaluation, so telemetry + readers must not treat `suppress` as an evaluated decision. +- Router seam: stable code depends on + `AdvisorRouter.evaluate(state) → { advisorWouldHelp, consequence, metadata? }`. + The `@opencode/ai` Evaluation/System One adapter stays behind this seam in + `zen-evaluation.ts`/`zen-router.ts`; only those `zen-*.ts` files may import + evaluation types (enforced by `router.test.ts`), and `index.ts` is the + composition point. The no-direct-`effect`-import guard (`router.test.ts`) + excludes `.test.` files, so host-path validation tests may import `effect` + while the manifest must never pin it. The adapter resolves auth through + `ctx.integration.connection.active("opencode")` + `resolve` and falls back to + the public bearer exactly like the host's own provider plugin; it never reads + key files or invents env-var contracts. `SystemOne.model` appends `/systemone` + itself — configure the `…/zen/v1` base, not the full endpoint. Official V2 docs + expose no Evaluation/System One API or changelog, so verify Zen behavior + against opencode source and the installed `@opencode/ai` types, never docs. +- Zen chain: each opportunity restarts from the top of `routing.models` and + resolves every failure into one of three outcomes. `retry` + (Transport/ProviderInternal/UnknownProvider — transient transport and generic + infrastructure) retries the SAME model up to `MAX_ATTEMPTS_PER_MODEL` with + backoff, then fails open without walking the chain, because a model change + cannot plausibly resolve generic infrastructure. `fallback` + (QuotaExceeded/RateLimit — quota exhaustion, model-specific capacity, or + model-specific rate limiting) advances to the next model immediately. + `terminal` (Authentication/ContentPolicy/InvalidRequest/Timeout/ + UnsupportedOperation/InvalidProviderOutput and non-AIError) fails open for the + opportunity without walking the chain. None of the outcomes consume budget. + An exhausted fallback chain normalizes the terminal throw to a `terminal` + disposition, preserving the last model, error class, and total attempts. + No reliable free-vs-paid pre-signal exists for System One models: they are + absent from the host model catalog (`ctx.model.list()` exposes enabled models + only, and the catalog has no `jev-1.13*` entries), and the Zen `/v1/models` + listing marks neither free nor paid models. Eligibility is therefore learned + at runtime: a terminal Authentication failure — the paid-model-on-public-token + rejection verified live — marks that model ineligible in a session-scoped + cache when the active Zen credential is the public bearer (`isPublicAuth` on + the evaluation seam, backed by `resolveZenToken`). Later opportunities skip an + ineligible model without attempting it and record the same terminal + `Authentication` failure with `attempts: 0`; the configured `routing.models` + chain is never mutated; the cache is bounded like the other session state and + cleared on `session.deleted`; and a missing or failing public-auth probe leaves + caching disabled (fail open). Two sharp edges: a 5xx caused by free-tier + capacity is indistinguishable from generic infrastructure 5xx and fails open + instead of falling back; and a model cached ineligible under the public bearer + stays skipped until `session.deleted` even if credentials change mid-session. + `x-should-retry` governs the same-model retry decision only, matching the host + `isRetryable` semantics verified in opencode source + (`packages/ai/src/provider-error.ts`, consumed by the session runner's retry + policy): `true` forces a same-model retry on any class, `false` forbids a + same-model retry (fallback classes still fall back, retry classes become + terminal) and never by itself forbids a fallback model; the header lookup is + case-insensitive. `RouterError.failure` carries model/attempts/errorClass plus + the resolved disposition into telemetry. Continuous System One scores are + rounded half-up onto the discrete 0-4 rubric and clamped, and the raw score, + per-level probabilities, and confidence are preserved in assessment metadata + and telemetry alongside the normalized value. Every adapter call carries a + caller deadline (`ZEN_CALL_TIMEOUT_MS`, 5s) that aborts the evaluation and + surfaces a classified `Timeout` AIError, so a hung provider call cannot hold + the primary dispatch. +- Telemetry: `ctx.storage` keys `head` + `evt:`; cap 5000 with + oldest-first eviction, writes serialized in-process and fail-open, reads + paginated within the host scan limit (≤1000). Events store the fingerprint + digest, decision, policy snapshot, router model/attempts, latency, error class + plus failure disposition, the raw and normalized consequence with the score + answer's probabilities/confidence when provided, advisor model, the compact + `advisorContext` diagnostics (completeness, omitted/included counts, estimated + prompt tokens, input budget), the `skipReason` for a graceful model-limits + skip, and delivery outcome — never transcript text, credentials, or secrets. + A failed automatic consultation records `ConsultationError` with a `terminal` + disposition; router failures keep their Zen class and resolved disposition. + The head is + reserved before the event write, so a crash can never reuse a sequence; an + event write that fails after the head write leaves a permanent sequence hole + (sparse telemetry, never duplicate ids) and can advance the eviction window + past the missing event. RPC + `experimental.auto-advisor` exposes only `telemetry.query` and + `telemetry.event` (no mutation surface). The host RPC path silently strips + event fields the schema does not declare (Effect decode discards excess + properties instead of erroring), so every field `routing-observer.ts` can + emit must exist as an optional schema property — verify with a + maximal-event round-trip test through the host's real validation path, not + by reading the schema. Telemetry writes serialize through one process-wide + queue: a hung store stalls later events (sparse/lost telemetry) but never + the hook, which never awaits it. +- Reentrancy: the only routing trigger is the primary `context` hook. Advisor + consultation (`ctx.generate.text`) and Zen evaluation run on host paths that + do not fire that hook, and own advice is excluded from material capture, so neither + automatic consultations nor their output can recursively create routing + opportunities. `routing-observer.test.ts` covers the auxiliary-kind skips and + the same-turn reinjection path. +- Delivery and lifetime: accepted `active` advice is injected into privileged + `event.system` as a text part, prefixed `[Auto Advisor automatic advice]`. + Never fall back to chronological message updates, synthetic user input, or a + fabricated tool call (`session.synthetic()` lowers to a user-role message, so it + cannot carry privileged reviewer authority). Changing the leading prompt may + affect prefix caching. + Advice is delivered into privileged `event.system` first; the latest successful + automatic review is then superseded in memory immediately and persisted + best-effort asynchronously for future requests — the hook never awaits + storage in either direction. Telemetry persistence is fire-and-forget with + failures consumed; retained hydration runs once per session in the background + and the hook uses only the synchronous cached state (a first request after + process startup may miss historical advice; absence, failure, and malformed + reads are cached; `observe` never hydrates). A storage failure never delays or + suppresses otherwise valid current + advice, and the new review stays authoritative in-process (only restart + durability may be lost). An oversized review is delivered in full but not + retained, and still supersedes the previous retained review. A dispatch with + fresh advice carries fresh advice only; the old review feeds the new Advisor + consultation as historical context. The retained review is reinjected into + later eligible system contexts as + clearly historical reviewer guidance (and as evidence in later Advisor + consultations), never touching fingerprints or Jev input. A newer successful + review replaces the old one; there is no compaction protocol because the + retained note lives outside the conversation transcript. Injection failures + fail open with `delivered: false`; deletion/disposal must + invalidate pending operations before any awaited cleanup to prevent late advice. +- Retained hook-contract pins: `routing-observer.test.ts` and + `retained-review.test.ts` must change together on any retained-seam edit — + the `reads()==1` (exactly-once background hydration) and `reads()==0` + (`observe` never hydrates) counting assertions are the permanent guards. + Single-flight holds only because `state.hydration` is assigned synchronously + in the same tick as the `hydrate()` call, before any await gap. Absence is + cached for the session lifetime even for transient read failures or malformed + payloads (fail-open by design; session IDs are not reused), so a failed + hydration never retries. +- Session cleanup: there is no session-close hook, so `index.ts` subscribes to + `ctx.event.subscribe` (`session.deleted`) and clears snapshots, turn state, + and live advice; setup cleanup aborts the subscription and disposes RPC, + routing, the Zen runtime, and the tool. Session cleanup must use `forget` + (it deletes the overlay entry and blocks late-hydration resurrection); + `clear` only tombstones to hydrated-empty while keeping the entry for + absence caching, and has no production callers. +- Known limits carried forward: both consultation paths use safe model-aware + projection; token estimation is approximate, and `advisor.timeoutMs` is a soft + deadline without provider cancellation. Shipping `active` as opt-in + experimental on the `off` default is + the accepted risk, and live calibration of the 25% reserve is still required + before recommending `active` broadly; + `sanitizeUri` preserves http(s) path segments, so a secret embedded in a URL + path can still reach the prompt (query strings and fragments are stripped, but + paths are not); no-user turns fall back to durable history in real flows (the + in-flight flag asymmetry keeps hook and durable no-user keys from coinciding) — + changing that needs an explicit design decision, not a key-format tweak. + +## V2 Install and Compatibility + +- This package is **V2-only** and targets exact `@opencode/plugin` / `@opencode/ai` + **2.0.21**, the approved baseline. The rest of this monorepo has separate pins; + do not copy this pin into the older packages without an intentional upgrade. +- Server plugins register in the V2 server profile (`~/.config/opencode/opencode.json`) + under the plural `"plugins"` key; use `@latest` or an exact pin, never `@v2`. +- A filesystem directory target resolves through the package-root `server.js` + wrapper, so build before registering a local directory and never point the + config at `server.js` or `dist/index.js` directly. +- Do not use V1 `server`/`config` hook signatures, `WithInstance`, or string + event buses.

Do not + patch private TUI internals, invent a transcript row, or add a private spinner. +- Reviewing status is scoped to actual automatic inference; success pulse lasts + about 2.5s.

Only add when code isn't self-explanatory. +- No `console.log`. Explicit `advisor()` failures stay visible through the tool + result returned by `registerPlugin`. +- Colocate tests with source files (`src/index.test.ts`). +- Imports: builtins first, then external, then relative, with `.js` suffixes. +- Keep files under ~150 lines; split before growing past that. +- `import type` for type-only imports (Biome `useImportType` is an error). + +## Testing Guidelines + +- Location: colocated +- Framework: bun test +- Running Tests: `bun test` +- Unit tests use mock contexts. Config tests write fixtures to a `mkdtemp` temporary + directory and pass an explicit `path`; the real OpenCode config directory is + never read or written. +- Runtime smoke: `bun run smoke` loads the **built** package-root `server.js` + (never a stale `dist/*` entry) under private config roots. The smoke is a + linear seam check only: entries load, tool schema, hook registration, one + explicit consult, one automatic delivery to privileged system, retained + write/read, RPC registration, idempotent cleanup. Advice must + enter `system`, never create a conversation message. Structural smoke is not + proof of real provider encoding: separately run exact-host 2.0.21 probes and + assert advice occupies the actual privileged wire system prompt. +- When product semantics change, update the smoke scenario to match (a retained + read needs a non-accepted turn; detached durable writes need a bounded settle + poll), or the seam check asserts stale behavior. +- Live verification (2.0.21): a real `opencode run --standalone` loads the built + package, uses a local OpenAI-compatible provider stand-in, and checks that the + context hook sees the assembled request, the merged advisor prompt contains the + hook-only system prompt exactly once plus the current assistant delta exactly + once, and the hook turn key matches the durable user message id. Keep probe + fixtures in tmpdirs with private `OPENCODE_CONFIG_DIR`/`XDG_*` roots. +- Child-session probes: only the host `subagent` tool/command creates a native + child (`session.create` takes no `parentID`; `session.fork` yields a root fork + with `parent_id: null`). Identify the child on the wire by the + `x-opencode-session-id`/`x-opencode-parent-session-id` pair (both non-empty, + actual ≠ parent) — `x-opencode-session` is a parent/child-shared affinity value, + and a nonce echoed in subagent arguments/results also appears in the parent's + own continuation. +- Run live probes against one explicit loopback host: a managed `api`/TUI start + with no explicit host silently targets the normal service and ignores a fresh + profile. +- Private `OPENCODE_CONFIG_DIR` isolates config but not provider auth or the + host data dir: live retention/telemetry land in the default database, so plan + probe sessions and read-only verification accordingly. +- Free Zen (`*-free`) models refuse non-interactive `ctx.generate.text` on 2.0.21 + (upstream free-tier gate), so live Advisor probes need a non-free `advisor.model`. +- 2.0.21 serves RPC at `POST /api/rpc/:rpcID/:method`: pass `rpcID`/`method` as + path params and `{"input": ...}` as the body, never all three in the body. +- The plugin emits no logs by design, so live delivery is verified from outside: + resolve the host DB with `opencode debug paths db` and read plugin storage + read-only (`sqlite3 -readonly`, `kv` table, keys under + `plugin::` — event keys carry no literal plugin name, so + match the hex prefix, not the text). +- Denial-behavior tests live in `routing-observer.test.ts` and + `advisor-tool.test.ts`, not `eligibility.test.ts`: eligibility contract changes + must update those files in the same pass. +- Zen is bundled into `dist/index.js` (there is no standalone + `dist/zen-evaluation.js`), so endpoint instrumentation must patch the bundled + base-URL literal in a private copy of the bundle. +Historical evidence below is not a substitute for fresh 2.0.21 remediation gates: + +- The 2.0.18 probe is documented as BLOCKED by the upstream stateless-generation + header issue (`ctx.generate.text` omitted `x-opencode-session`), not a + context-capture failure. +- 2.0.19 assembled-request fidelity probe PASSED: an Executor called `advisor()` + without reading repo files and the Advisor recovered repo instructions absent + from the user prompt (merge-commit merges, retain remote branch). +- 2.0.19 in-flight delta fidelity probe PASSED: an Executor emitted a glob tool + call with a unique nonce plus `advisor()`, the nonce existing only in the + sibling tool-call args, and the Advisor recovered the exact nonce. +- 2.0.19 #50 runtime probe PASSED (private tmpdir `OPENCODE_CONFIG_DIR`/`XDG_*`, + `opencode run --standalone --auto`, local OpenAI-compatible executor stand-in, + real `opencode.ai/zen/v1/systemone` with the public bearer): `off` produced + zero telemetry, zero advisor calls, and no advice; `observe` produced two real + Zen evaluations with telemetry (policy, fingerprint, model, attempts, latency) + and no advisor call or delivery; `active` produced a real Zen evaluation, an + advisor call through the stand-in, telemetry `delivered: true`, and the + advice landed in the same in-flight dispatch that triggered the evaluation + (host lowers it to ``-wrapped tail text on the wire) with + reinjection on the tool-result continuation.

It adds +the zero-argument `advisor()` tool and an optional, experimental automatic review +router. The package is version `2.0.0` but has **not been published**; use it from +this repository's checkout for now. + +## What it does + +### Explicit review + +The Executor can call `advisor()` with no arguments. The Advisor receives the +current session context, including tool activity and the work in progress, and +returns a concise review. Each call uses a fresh, stateless generation; no ongoing +Advisor conversation is kept. The Advisor has no tools to inspect files, run shell +commands, or delegate work; its instructions also tell it not to ask questions or +start another consultation. It is prompted to give qualitative advice, not scores +or confidence claims. + +The selected Advisor model defaults to the in-flight Executor model. Set +`advisor.model` to use another model. Explicit calls do not use Jev routing or +the automatic per-turn consultation quota. An explicit call marks its captured +state reviewed, so automatic routing does not immediately consult again on the +same state; it does not spend the automatic quota. Model and provider errors, +including timeouts, are returned in the tool result; the plugin does not switch +to a fallback Advisor model. + +### Automatic review + +Automatic routing runs at the awaited primary `session.context` dispatch +boundary. It is off by default and can be enabled globally with `routing.mode`: + +| Mode | Behavior | +| --- | --- | +| `off` | No automatic routing. The explicit `advisor()` tool remains available. | +| `observe` | Sends a bounded routing projection to Zen/System One, evaluates the policy, and records metadata. It does not call the Advisor or inject an automatic review. Shared tool-use guidance may still be added when the tool is available. **This mode is not local-only.** | +| `active` | Uses the same router and calls the Advisor when both policy thresholds pass and the per-turn quota is available. The pending Executor request waits for the review; accepted advice is added to its privileged system context. | + +The router evaluates whether independent review could change the Executor's +immediate next action and scores the consequence from 0 to 4. An automatic +consultation is accepted only when both `advisorWouldHelp` and `consequence` +meet their configured thresholds. The default thresholds are `0.7` and `3`. + +An unchanged request fingerprint is not reviewed again. New user input or +material tool/execution results can open another opportunity; Advisor-originated +activity alone does not. The default quota is one accepted automatic consultation +per user turn. In `active`, acceptance consumes it before the Advisor call, even +if that call fails. When the quota is exhausted, the Jev classifier is skipped; +`observe` consumes the same quota hypothetically on policy acceptance and keeps +evaluating for calibration. Explicit `advisor()` calls never consume it. + +Automatic routing and delivery fail open: a router, Advisor, timeout, or +injection failure does not block the primary Executor dispatch. An Advisor +failure does not switch to another Advisor model. Successful +new and retained advice are delivered through privileged system context, not as +a chronological message update, synthetic user message, or fabricated tool +call. This may change the provider's leading system-prompt prefix and affect +prefix caching. The Executor gets reviewer guidance only when the `advisor` tool +is available. That guidance ranks user constraints first, then direct evidence +and tool results, then the Advisor's review, then speculation; conflicts should +be reconciled rather than followed blindly. + +The native permission action is `advisor`. A native denial removes the explicit +tool and blocks automatic review, regardless of agent name. Root sessions may be +eligible; parented child sessions are never eligible. + +In OpenCode V2, set `default_agent` at the top level and put the rule under that +agent's `permissions` array. For example, this denies Auto-Advisor for the +`build` root agent: + +```json +{ + "$schema": "https://opencode.ai/config.json", + "default_agent": "build", + "agents": { + "build": { + "permissions": [ + { "action": "advisor", "resource": "*", "effect": "deny" } + ] + } + } +} +``` + +V2 permission rules are ordered; later matching rules take precedence. Keep the +deny after any rule that would allow `advisor`, including any applicable +session-level rule. This is the V2 `agents` object and permissions array, not the +V1 `agent` map format. + +## Configuration + +Configuration is global and sparse. The file is +`$OPENCODE_CONFIG_DIR/auto-advisor.json` when `OPENCODE_CONFIG_DIR` is set; +otherwise it is `$XDG_CONFIG_HOME/opencode/auto-advisor.json`, or +`~/.config/opencode/auto-advisor.json` when `XDG_CONFIG_HOME` is unset. + +```json +{ + "advisor": { + "model": "inherit", + "timeoutMs": 300000 + }, + "routing": { + "mode": "off", + "models": ["jev-1.13-free", "jev-1.13"], + "advisorWouldHelpThreshold": 0.7, + "consequenceThreshold": 3, + "maxConsultationsPerTurn": 1 + } +} +``` + +All seven settings and defaults: + +| Setting | Default | Accepted values | +| --- | --- | --- | +| `advisor.model` | Inherit the Executor model | `"inherit"` or a `providerID/modelID` reference | +| `advisor.timeoutMs` | `300000` (5 minutes) | Positive integer up to `2147483647` | +| `routing.mode` | `"off"` | `"off"`, `"observe"`, or `"active"` | +| `routing.models` | `["jev-1.13-free", "jev-1.13"]` | Non-empty array of ordered model IDs | +| `routing.advisorWouldHelpThreshold` | `0.7` | Number from 0 to 1 | +| `routing.consequenceThreshold` | `3` | Number from 0 to 4 | +| `routing.maxConsultationsPerTurn` | `1` | Positive integer | + +Omit any setting to use its default. Malformed JSON, unknown keys, and invalid +values produce configuration errors; they do not silently fall back to defaults. +Do not put credentials in this file. + +## Context, storage, and limits + +Both explicit and automatic consultations use the selected Advisor model's +advertised limits from OpenCode's model catalog. The reserve is +`max(contextLimit * 0.25, outputLimit)` with no rounding or floor; the input +budget is `min(inputLimit ?? infinity, contextLimit - reserve)`. This is an +estimate, not a provider guarantee. +When the captured context does not fit, the plugin keeps whole entries by +priority: system instructions and task constraints, current user turn, current +assistant/tool state, compaction/checkpoint entries, then history. Oversized +entries are skipped and selection continues with later entries. The plugin does +not summarize, truncate, or otherwise compress them. Hidden assistant reasoning +is excluded; media is represented by metadata, not its contents. An omission +marker tells the Advisor when context was left out. The final estimated prompt, +including mandatory instructions and any marker, must fit the budget. + +If model limits are missing or the prompt framing cannot fit, automatic review +is skipped and the Executor proceeds. The explicit tool returns an error instead. +`advisor.timeoutMs` is a soft deadline: `ctx.generate.text` has no cancellation +signal, so the plugin stops waiting after the deadline, but the underlying +stateless generation may continue. Automatic timeouts fail open; explicit +timeouts are shown in the tool result. Jev routing has a separate, abortable +5-second caller deadline. Transport, provider-internal, and unknown-provider +errors retry the same model at most once; quota and rate-limit errors fall back +to the next configured model; other error classes fail open without another +attempt. `x-should-retry: true` forces a same-model retry; `false` prevents that +retry but does not prevent quota/rate-limit fallback. An Authentication failure +on the public bearer marks that Jev model ineligible for the current session; +the configured model list is unchanged. These Jev rules do not provide an +alternate Advisor model. + +Automatic advice is delivered into privileged system context first; the latest +successful automatic review is then superseded in memory immediately and +persisted best-effort as one small bounded record per session +(`auto-advisor:retained:`, internal 8192-char limit), not a history +archive. The hook never waits for storage in either direction: telemetry +persistence is fire-and-forget with failures consumed, and retained hydration +runs once per session in the background while the hook uses only the +synchronous cached state (a first request after process startup may miss +historical advice; `observe` never hydrates). A storage failure cannot delay or +suppress otherwise valid current advice, and the new review stays authoritative +in-process (only restart durability may be lost). An oversized review is +delivered in full but not retained, and still supersedes the previous retained +review. A dispatch carrying fresh advice contains the fresh review only; the +previous review feeds the new Advisor consultation as historical context. The +retained review is reinjected on later eligible requests as clearly historical +reviewer guidance and may inform later Advisor consultations, while staying out +of routing fingerprints and Jev input. It survives conversation compaction +because it lives outside the transcript. Session deletion clears it. + +When storage and RPC are available, `experimental.auto-advisor` exposes only +read-only methods: +`telemetry.query({ after?, limit? })` and `telemetry.event({ seq })`; the query +returns `{ events, next? }`, and the event lookup returns one event or `null`. +Telemetry records routing and delivery metadata, model/latency/outcome details, +and context-fit counts. It does not store the captured transcript or Advisor +response. The latest successful advice is kept separately as one bounded +retained review for continuity. The optional TUI uses the distinct +`experimental.auto-advisor.review` RPC, with `status({ sessionID })` and +`review.started` / `review.finished` lifecycle events; this surface contains only +status and final advice, not Advisor confidence. + +## Optional TUI + +OpenCode V2.0.21 can discover the package's TUI entrypoint from the configured +server package root; the server runtime itself loads only the server entrypoint. +The TUI plugin has the distinct ID +`capybearista.opencode-auto-advisor-tui`. +The TUI adds: + +- `Auto-Advisor reviewing` in the footer during an actual automatic Advisor + generation. +- A transient `✓ Auto-Advisor finished` status for about 2.5 seconds after success. +- The latest completed automatic advice above the composer. A newer successful + review replaces it. + +The TUI shows final advice only. It does not add chat rows, expose inputs, +reasoning, routing probabilities, or telemetry, or change the composer input. +The lifecycle RPC has separate start/finish events and status snapshots so the +TUI can reconstruct current status. OpenCode 2.0.21 supports reconnecting to the +same endpoint; replacing a managed endpoint, port, or auth requires a TUI +restart because the SDK client is captured at setup. Visual behavior at narrow +terminal widths, with long advice, and alongside the Executor response still +needs manual checking. + +To disable only this TUI plugin, use its plugin ID in `cli.json`: + +```json +{ + "$schema": "https://opencode.ai/v2/cli.json", + "plugins": ["-capybearista.opencode-auto-advisor-tui"] +} +``` + +The negative string is a TUI plugin removal directive by ID, not a package +specifier or an object-form plugin entry. + +## Install from this checkout + +For this repository's local checkout, put the following in an `opencode.json` +located at the repository root. The directory target is the package root, not +`server.js` or a file under `dist/`: + +```json +{ + "$schema": "https://opencode.ai/config.json", + "plugins": ["./packages/opencode-auto-advisor"] +} +``` + +The package is still version `2.0.0` and is not available from npm. First +publication must use the repository-approved bootstrap after final validation, +manual checks, and merge; it publishes `2.0.0` without an artificial patch +Changeset. That bootstrap/release operation is not approved or implemented in +this pass. Later releases use normal Changesets. Until then, use the local +directory target above. + +## Requirements and development + +- OpenCode V2; V1 is not supported. +- `@opencode/plugin` and `@opencode/ai` peer dependencies are pinned to `2.0.21`. +- The optional TUI uses `@opentui/core` and `@opentui/solid` `>=0.5.14`, and + `solid-js` `>=1.9.0`. + +From this package directory: + +```bash +bun run build # compile server and TUI entrypoints +bun test # run package tests +bun run typecheck # type check +bun run lint # Biome check +bun run smoke # build and load the built server entrypoint +``` + +The build bundles the server implementation, including the Zen adapter, into +`dist/index.js`, which the package-root `server.js` loads. It does not produce a +runtime `dist/zen-evaluation.js` file. The TUI is bundled separately as +`dist/tui.js`; the server entrypoint does not import TUI code. + +## Focused manual checks + +Use a separate config directory when testing; do not change a regular OpenCode +profile. The following are checks to perform, not a completion report: + +The [focused manual procedure](../../docs/plans/opencode-auto-advisor-manual-test.md) +provides isolated setup, inspection commands, and all 18 acceptance scenarios. + +1. Load the built package by its directory target. Confirm the zero-argument + `advisor()` tool is available in an eligible root session and hidden when the + native `advisor` permission denies it; confirm a parented child is ineligible. +2. With `routing.mode` set to `off`, confirm explicit consultation still works + and there is no automatic routing. In `observe`, verify the Jev request and + telemetry without an Advisor call or automatic advice delivery; shared + advisor-tool guidance may still be present in the request. +3. In `active`, exercise an opportunity that passes both thresholds. Inspect the + actual provider request: advice must be in the privileged system prompt, not + a lower-authority system-update tail, user message, or fake tool result. Check + that a failed review leaves the Executor moving and does not switch Advisor + models. +4. Verify the latest accepted advice remains available on a later turn and through + OpenCode conversation compaction (the retained note lives outside the + transcript; a newer review replaces it). Check the TUI's reviewing/success + status and final-advice panel, plus narrow-width and long-advice rendering. + +Final automated gates and manual wire/UI checks are still pending. The first +publication must wait for those checks and merge. A release check can report +HTTP 404 for a never-published package; that is expected before first publish. + +Not part of this release: cancellable Advisor generation, an opt-in for hidden +reasoning, more aggressive tool/media compression, semantic compaction, a +Decisions API, Advisor-model fallback, or routing benchmarks. These remain +post-release work, not available settings. + +## License + +MPL-2.0 diff --git a/packages/opencode-auto-advisor/bunfig.toml b/packages/opencode-auto-advisor/bunfig.toml new file mode 100644 index 0000000..7693482 --- /dev/null +++ b/packages/opencode-auto-advisor/bunfig.toml @@ -0,0 +1 @@ +preload = ["@opentui/solid/preload"] diff --git a/packages/opencode-auto-advisor/package.json b/packages/opencode-auto-advisor/package.json new file mode 100644 index 0000000..5fc413a --- /dev/null +++ b/packages/opencode-auto-advisor/package.json @@ -0,0 +1,64 @@ +{ + "name": "@capybearista/opencode-auto-advisor", + "version": "2.0.0", + "description": "OpenCode V2 plugin that provides an independent Advisor: explicit zero-argument consultation, experimental Zen automatic routing with observe and active modes, digest-only telemetry, same-turn system-context advice delivery, and one bounded latest retained automatic review for later turns", + "author": "capyBearista ", + "repository": { + "type": "git", + "url": "https://github.com/capyBearista/opencode-plugins.git", + "directory": "packages/opencode-auto-advisor" + }, + "type": "module", + "license": "MPL-2.0", + "main": "./dist/index.js", + "types": "./dist/index.d.ts", + "exports": { + ".": { + "types": "./dist/index.d.ts", + "default": "./dist/index.js" + }, + "./tui": { + "types": "./dist/tui.d.ts", + "default": "./dist/tui.js" + } + }, + "files": [ + "dist", + "server.js", + "tui.js" + ], + "scripts": { + "build": "rm -rf dist && tsc --project tsconfig.build.json --emitDeclarationOnly && bun build src/index.ts --outfile=dist/index.js --target=bun --external '@opencode/*' && bun build src/tui.ts --outfile=dist/tui.js --target=bun --external '@opencode/*' --external '@opentui/*' --external 'solid-js'", + "typecheck": "tsc --noEmit", + "lint": "bunx @biomejs/biome check .", + "check": "bunx @biomejs/biome check --write .", + "ci": "bunx @biomejs/biome ci .", + "test": "bun test", + "smoke": "bun run build && bun scripts/smoke-built.ts" + }, + "peerDependencies": { + "@opencode/ai": "2.0.21", + "@opencode/plugin": "2.0.21", + "@opentui/core": ">=0.5.14", + "@opentui/solid": ">=0.5.14", + "solid-js": ">=1.9.0" + }, + "devDependencies": { + "@opencode/ai": "2.0.21", + "@opencode/plugin": "2.0.21", + "@opentui/core": "0.5.14", + "@opentui/solid": "0.5.14", + "solid-js": "1.9.12" + }, + "peerDependenciesMeta": { + "@opentui/core": { + "optional": true + }, + "@opentui/solid": { + "optional": true + }, + "solid-js": { + "optional": true + } + } +} diff --git a/packages/opencode-auto-advisor/scripts/smoke-built.ts b/packages/opencode-auto-advisor/scripts/smoke-built.ts new file mode 100644 index 0000000..1a774ec --- /dev/null +++ b/packages/opencode-auto-advisor/scripts/smoke-built.ts @@ -0,0 +1,164 @@ +import { tmpdir } from "node:os";
