From 5418e4c0bc5fafceefcca457e08fd76b1df59e9b Mon Sep 17 00:00:00 2001 From: Arjun Pramanik Date: Wed, 28 Oct 2026 02:44:00 +0000 Subject: [PATCH 01/42] feat(auto-advisor): rebuild Auto Advisor on OpenCode 2.2.0 Zero-argument advisor() tool plus Decision-model-triggered automatic reviews (moment + consequence), delivered at the tail of the current request and as an instruction entry, never by editing the system prompt. Observe mode logs JSONL telemetry; the TUI shows review status. One opencode.json entry loads both halves. --- AGENTS.md | 8 +- README.md | 17 +- bun.lock | 32 +- docs/README.md | 1 + docs/auto-advisor/findings.md | 51 ++ packages/opencode-auto-advisor/AGENTS.md | 47 ++ packages/opencode-auto-advisor/LICENSE.txt | 373 +++++++++++++++ packages/opencode-auto-advisor/README.md | 120 +++++ packages/opencode-auto-advisor/bunfig.toml | 4 + packages/opencode-auto-advisor/package.json | 63 +++ .../scripts/smoke-built.ts | 88 ++++ packages/opencode-auto-advisor/server.js | 1 + packages/opencode-auto-advisor/src/advisor.ts | 96 ++++ .../opencode-auto-advisor/src/config.test.ts | 85 ++++ packages/opencode-auto-advisor/src/config.ts | 201 ++++++++ .../src/decisions.test.ts | 158 +++++++ .../opencode-auto-advisor/src/decisions.ts | 188 ++++++++ .../opencode-auto-advisor/src/delivery.ts | 62 +++ .../src/fixtures/s1-decisions.json | 91 ++++ packages/opencode-auto-advisor/src/policy.ts | 48 ++ packages/opencode-auto-advisor/src/rpc.ts | 60 +++ .../opencode-auto-advisor/src/server.test.ts | 418 +++++++++++++++++ packages/opencode-auto-advisor/src/server.ts | 443 ++++++++++++++++++ .../opencode-auto-advisor/src/telemetry.ts | 58 +++ .../src/transcript.test.ts | 111 +++++ .../opencode-auto-advisor/src/transcript.ts | 165 +++++++ .../opencode-auto-advisor/src/tui.test.ts | 62 +++ packages/opencode-auto-advisor/src/tui.ts | 118 +++++ .../opencode-auto-advisor/src/units.test.ts | 138 ++++++ packages/opencode-auto-advisor/tsconfig.json | 10 + packages/opencode-auto-advisor/tui.js | 1 + tools/release-channel-guard.test.ts | 3 + tools/release-channel-guard.ts | 4 + tools/release-channels.json | 4 + 34 files changed, 3323 insertions(+), 6 deletions(-) create mode 100644 docs/auto-advisor/findings.md create mode 100644 packages/opencode-auto-advisor/AGENTS.md create mode 100644 packages/opencode-auto-advisor/LICENSE.txt create mode 100644 packages/opencode-auto-advisor/README.md create mode 100644 packages/opencode-auto-advisor/bunfig.toml create mode 100644 packages/opencode-auto-advisor/package.json create mode 100644 packages/opencode-auto-advisor/scripts/smoke-built.ts create mode 100644 packages/opencode-auto-advisor/server.js create mode 100644 packages/opencode-auto-advisor/src/advisor.ts create mode 100644 packages/opencode-auto-advisor/src/config.test.ts create mode 100644 packages/opencode-auto-advisor/src/config.ts create mode 100644 packages/opencode-auto-advisor/src/decisions.test.ts create mode 100644 packages/opencode-auto-advisor/src/decisions.ts create mode 100644 packages/opencode-auto-advisor/src/delivery.ts create mode 100644 packages/opencode-auto-advisor/src/fixtures/s1-decisions.json create mode 100644 packages/opencode-auto-advisor/src/policy.ts create mode 100644 packages/opencode-auto-advisor/src/rpc.ts create mode 100644 packages/opencode-auto-advisor/src/server.test.ts create mode 100644 packages/opencode-auto-advisor/src/server.ts create mode 100644 packages/opencode-auto-advisor/src/telemetry.ts create mode 100644 packages/opencode-auto-advisor/src/transcript.test.ts create mode 100644 packages/opencode-auto-advisor/src/transcript.ts create mode 100644 packages/opencode-auto-advisor/src/tui.test.ts create mode 100644 packages/opencode-auto-advisor/src/tui.ts create mode 100644 packages/opencode-auto-advisor/src/units.test.ts create mode 100644 packages/opencode-auto-advisor/tsconfig.json create mode 100644 packages/opencode-auto-advisor/tui.js diff --git a/AGENTS.md b/AGENTS.md index 24a5e91..9d979ef 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -19,7 +19,7 @@ Subdirectories contain specialized files that extend these rules. ### Plugin Development (MUST) -Scope: V1 packages.

The tail push covers the current step, and the entry covers every later one. +- **Never append to the last message.** On a continuation step it is a `tool` message, and the Anthropic lowering accepts only tool-result parts there. +- **The `context` hook re-fires on a retried step.** The retry may already carry the entry from the failed attempt. `stateKey` ignores system messages and memoizes the outcome; the marker stops a second copy. +- **Hooks and `generate.*` calls can't be cancelled.** A consult that outlives its run is dropped by the session epoch, which is bumped on `session.execution.{succeeded,failed,interrupted}`. +- **Synthetic, skill, shell and compaction messages are `role: "user"` too.** The turn key prefers ids recorded by the `prompt` hook. +- **`generate.text` without a model uses the global default**, not the agent's. Always pass the agent's `event.model` for "inherit". +- **Decision errors are plain objects with `_tag`.** A provider without credentials reports `Generate.ModelNotFoundError`, not an auth error. Shapes are in `src/fixtures/s1-decisions.json`. +- **The host retries rate limits itself.** The router never retries; it skips a throttled model for 60 s instead of stalling every step. +- **One `opencode.json` entry loads both halves**; `cli.json` needs none. The TUI gets `context.options = {}`, so configuration stays server-side. +- **Neither hook may throw into the user's request.** Failures are swallowed. + +## Testing Guidelines + +- Location: colocated (`src/*.test.ts`). `bunfig.toml` preloads `@opentui/solid/preload` for the TUI tests. +- Tests set `OPENCODE_CONFIG_DIR` and `XDG_DATA_HOME` to temp dirs; never read the real `HOME`. +- `src/server.test.ts` drives a fake host context. Request shapes match what a real 2.2.0 `context` hook delivers. +- Hook, delivery or protocol changes need a live check against real 2.2.0.

A Claude Code-style Advisor for OpenCode: a stronger model reviews your agent's work when it asks, or automatically at the moments that matter.

+

+ npm version + npm downloads + opencode + license +

+ +--- + +## Why? + +> Most turns of a coding task are routine, but a few decide the outcome: committing to an approach, getting stuck on the same failure, declaring the work done. Claude Code's [Advisor](https://code.claude.com/docs/en/advisor) lets the agent consult a stronger model at those moments. This plugin brings the same idea to OpenCode, and adds a way to catch those moments even when the agent doesn't ask. + +## Philosophy: Extending OpenCode + +OpenCode is designed to be highly extensible. This plugin uses only public V2 plugin APIs: a tool, the `context` hook, host-resolved [Decision models](https://opencode.ai/docs/en/zen/#jev), stateless generation, and session instruction entries. It never edits the system prompt, so it doesn't break the provider's prompt cache. + +### Architecture + +```mermaid +flowchart LR + E[Executor step] --> D{Decision model:
moment + stakes} + D -- routine or low stakes --> E + D -- approach / stuck / done --> A[Advisor model] + E -- "advisor()" --> A + A -- advice --> E +``` + +Two paths reach the same stateless Advisor. The agent can call the `advisor()` tool itself. In `active` mode, a fast Decision model also reads each step, and the plugin consults the Advisor when the agent is at one of Claude Code's three moments and a wrong next step would cost something. + +## Features + +- **Explicit `advisor()` tool**: zero arguments. The Advisor reads the agent's system prompt, tool list and transcript, and returns concise, actionable advice as the tool result. +- **Automatic reviews (opt-in)**: a Decision model classifies each step as `approach`, `stuck`, `done` or `routine`, and scores how costly a mistake would be (0–4). The plugin consults the Advisor when both pass your thresholds. +- **Advice on the same step**: the review reaches the waiting request immediately, and stays in the session as an instruction entry until a newer review replaces it. +- **Cache-safe**: no system-prompt edits. Only the newest message of a request changes. +- **Observe mode**: run the Decision model without consulting, and log what it would have done, to tune the thresholds. +- **TUI status**: "Advisor reviewing…" in the prompt footer, and the latest review above the composer. + +## Install + +### OpenCode V2 + +Requires OpenCode **2.2.0** or later. + +This plugin has a Server component + TUI component. + +Add one entry under the `"plugins"` key in `opencode.json(c)`: + +```json +{ + "plugins": ["@capybearista/opencode-auto-advisor@latest"] +} +``` + +The TUI half loads automatically, so `cli.json` needs no entry. + +### OpenCode V1 + +Not available. The plugin depends on OpenCode 2.2.0's Decision and instruction-entry APIs. + +### Uninstall + +Remove the entry from `"plugins"` in `opencode.json(c)`. Optionally delete `~/.config/opencode/auto-advisor.json` and the telemetry folder `~/.local/share/opencode/auto-advisor/`. + +## Usage + +- **Ask for a review**: the agent sees the `advisor()` tool and its guidance (consult after orienting, when stuck, before declaring done). You can also say "consult the advisor before you continue". +- **Turn on automatic reviews**: set `routing.mode` to `observe` first, watch the telemetry for a while, then switch to `active`. +- Automatic reviews run in top-level sessions only. Subagent sessions don't get the tool or automatic reviews. +- Automatic reviews are capped per user turn (`routing.maxConsultationsPerTurn`, default 2). Explicit `advisor()` calls don't count against the cap. + +## Configuration + +Global, optional, strict JSON at `~/.config/opencode/auto-advisor.json` (or `$OPENCODE_CONFIG_DIR/auto-advisor.json`, or `$XDG_CONFIG_HOME/opencode/auto-advisor.json`). A missing file means all defaults, an omitted key means its default, and an invalid file turns automatic reviews off (the explicit tool keeps working). Changes apply on the next step without a restart. + +```json +{ + "advisor": { "model": "openai/gpt-6" }, + "routing": { "mode": "active" } +} +``` + +| Key | Default | Description | +| :--- | :--- | :--- | +| `advisor.model` | `"inherit"` | `"provider/model"` of the Advisor, or `"inherit"` to use the agent's own model. | +| `advisor.timeoutMs` | `300000` | Soft deadline for one consult. An automatic consult that runs out fails open; an explicit one returns an error. | +| `routing.mode` | `"off"` | `off`, `observe` (Decision model only, logged), or `active` (consults and delivers). | +| `routing.models` | `["opencode/jev-1.13-free"]` | Ordered decision models, 1–8 `"provider/model"` refs. On an availability or auth failure, the plugin tries the next one. | +| `routing.momentThreshold` | `0.7` | Minimum probability that the step is not routine. | +| `routing.consequenceThreshold` | `1.5` | Minimum stakes score (0 trivial … 4 critical), compared unrounded. | +| `routing.maxConsultationsPerTurn` | `2` | Automatic consults per user turn. | + +## Privacy and cost + +- **Decision provider**: in `observe` and `active`, each step's latest request, recent tool calls and truncated results (no system prompt, no tool definitions) go to the configured decision model. The default, `opencode/jev-1.13-free`, is a limited-time free model on OpenCode Zen, built by TypeSafe AI. Check Zen's data-retention terms for it before using it with sensitive code. +- **Advisor**: each consult sends the agent's full transcript (up to the model's context) to the Advisor model, uncached. It's billed at that model's rates. +- **Latency**: in `active`, every step waits for one Decision call (about 0.1–0.4 s on Zen after a cold start). A consult pauses the agent until the Advisor answers. +- **Cache**: installing the plugin adds the `advisor` tool, which costs one prompt-cache miss on the tools block. After that, reviews only add to the end of a request. +- **Telemetry**: one JSON line per routing decision in `~/.local/share/opencode/auto-advisor/telemetry.jsonl` (capped at 5 MB, one rotation), with models, answers, verdicts and timings. Never transcript or advice text. + +## Troubleshooting + +- **Nothing happens automatically**: `routing.mode` defaults to `off`. Check `telemetry.jsonl` for the verdicts: `routine` and `low-consequence` mean the thresholds held the review back, and `no-decision` means no configured decision model answered. +- **"Advisor unavailable" in the footer**: the consult failed or timed out. The agent carried on without advice. +- **Your config is ignored**: an invalid file switches automatic reviews off. Fix the value named in the error; unknown keys are rejected. +- **Observe mode logs fewer lines than steps**: while one Decision call is still running, later steps in the same session are skipped rather than queued. + +## Contributing + +This package lives in the `opencode-plugins` monorepo.

The default, `opencode/jev-1.13-free`, is a limited-time free model on OpenCode Zen, built by TypeSafe AI. Check Zen's data-retention terms for it before using it with sensitive code. -- **Advisor**: each consult sends the agent's transcript (system prompt with OpenCode's catalogs left out when `advisor.compactContext` is on, up to `advisor.maxTokens`) to the Advisor model, uncached. It's billed at that model's rates. -- **Latency**: in `active`, every step waits for one Decision call (about 0.1–0.4 s on Zen after a cold start). A consult pauses the agent until the Advisor answers. +- **Decision provider**: in `observe` and `active`, each step's latest user request, recent tool calls and truncated results (no system prompt, no tool definitions) go to the configured decision model. The default, `opencode/jev-1.13-free`, is a limited-time free model on OpenCode Zen, built by TypeSafe AI. Check Zen's data-retention terms for it before using it with sensitive code. +- **Advisor**: automatic reviews are on by default and, without `advisor.model`, use the agent's own model. Each consult sends the agent's transcript (system prompt with OpenCode's catalogs left out when `advisor.compactContext` is on, up to `advisor.maxTokens`) to the Advisor model, uncached. It's billed at that model's rates. +- **Latency**: in `active`, every step waits for one Decision call (about 0.1–0.4 s on Zen after a cold start), except while a limit blocks consults: then the call runs in the background, as in `observe`. A consult pauses the agent until the Advisor answers. - **Cache**: installing the plugin adds the `advisor` tool, which costs one prompt-cache miss on the tools block. After that, reviews only add to the end of a request. - **Telemetry**: one JSON line per routing decision in `~/.local/share/opencode/auto-advisor/telemetry.jsonl` (capped at 5 MB, one rotation), with models, answers, verdicts and timings. Never transcript or advice text. ## Troubleshooting -- **Nothing happens automatically**: `routing.mode` defaults to `off`. Check `telemetry.jsonl` for the verdicts: `routine` and `low-consequence` mean the thresholds held the review back, and `no-decision` means no configured decision model answered. +- **Nothing happens automatically**: check `telemetry.jsonl` for the verdicts. `routine` and `low-consequence` mean the thresholds held the review back, `blocked` means the per-turn limit or the cooldown did (the `blocked` field says which), and `no-decision` means no configured decision model answered. - **"Advisor unavailable" in the footer**: the consult failed or timed out. The agent carried on without advice. - **Your config is ignored**: an invalid file switches automatic reviews off, and `advisor()` returns `invalid config: …` naming the bad value; unknown keys are rejected. With a local checkout, run `bun run build` after pulling: OpenCode loads `dist/`, and an older build rejects newer keys. -- **Observe mode logs fewer lines than steps**: while one Decision call is still running, later steps in the same session are skipped rather than queued. +- **Observe mode logs fewer lines than steps**: while one Decision call is still running, later steps in the same session are skipped rather than queued.

It now lives in a session.panel ("auto-advisor"): the whole review as rendered markdown in a scrollbox, with its moment, model, duration and time. A compact sidebar.footer widget shows the status and opens the panel on click; /advisor-review (also in the palette) toggles it, and esc/q and f close it or make it full screen. The widget and panel read the stored review through RPC when they mount, so a review from before a restart shows too (without details, which are memory only). New tui.sidebar (default true) hides the widget. --- docs/auto-advisor/findings.md | 6 + packages/opencode-auto-advisor/AGENTS.md | 6 +- packages/opencode-auto-advisor/README.md | 7 +- .../scripts/smoke-built.ts | 9 +- .../opencode-auto-advisor/src/config.test.ts | 7 + packages/opencode-auto-advisor/src/config.ts | 12 +- packages/opencode-auto-advisor/src/rpc.ts | 32 +- .../opencode-auto-advisor/src/server.test.ts | 18 +- packages/opencode-auto-advisor/src/server.ts | 19 +- .../opencode-auto-advisor/src/tui.test.ts | 264 ++++++++++++--- packages/opencode-auto-advisor/src/tui.ts | 304 +++++++++++++++--- 11 files changed, 594 insertions(+), 90 deletions(-) diff --git a/docs/auto-advisor/findings.md b/docs/auto-advisor/findings.md index 045ee25..f2d5c74 100644 --- a/docs/auto-advisor/findings.md +++ b/docs/auto-advisor/findings.md @@ -43,6 +43,12 @@ Verified 2026-10-28 on `@opencode/cli@2.2.0` with an isolated HOME/XDG, a local - Interrupt during a consult (`POST /api/session/:id/interrupt`, Advisor reply held 20 s): `session.execution.interrupted` aborted the consult after 4.4 s, telemetry recorded `stale`, nothing was delivered, and the interrupted step sent no model request. - Not covered live: compaction and child sessions.

With a local checkout, run `bun run build` after pulling: OpenCode loads `dist/`, and an older build rejects newer keys. diff --git a/packages/opencode-auto-advisor/src/advisor.ts b/packages/opencode-auto-advisor/src/advisor.ts index 5750589..5b2d114 100644 --- a/packages/opencode-auto-advisor/src/advisor.ts +++ b/packages/opencode-auto-advisor/src/advisor.ts @@ -1,5 +1,6 @@ import type { ModelRef } from "./config.js"; import type { Moment } from "./decisions.js"; +import type { Attempt } from "./fallback.js"; export const TOOL_NAME = "advisor"; @@ -57,40 +58,48 @@ export type GenerateText = (input: { model: ModelRef; }) => Promise<{ text: string }>; -export class AdvisorTimeoutError extends Error { - constructor(ms: number) { - super(`the Advisor did not answer within ${ms} ms`); +/** Every Advisor model failed; `attempts` says how, in chain order. */ +export class AdvisorChainError extends Error { + constructor(readonly attempts: readonly Attempt[]) { + const failures = attempts.map( + (attempt) => `${attempt.model}: ${attempt.error ?? attempt.outcome}`, + ); + super(`all models failed (${failures.join(", ")})`); + } +} + +/** No text back: the next model in the chain may still answer. */ +export class EmptyAdviceError extends Error { + readonly _tag = "Advisor.EmptyAdvice"; + constructor() { + super("the Advisor returned no advice"); } } /** - * One stateless consult.

The README now states the chain's real worst cases: a refused connection costs about 12 s because OpenCode retries it, and a silent provider costs its header or chunk timeout, with no skip. It also says that Esc stops the wait but not the provider request, and how many steps the log keeps at the maximum input size. findings.md records round 3's live check. The timeline tests now cover escaping the logged input and lines written before it existed. --- docs/auto-advisor/findings.md | 13 ++++++++++++- packages/opencode-auto-advisor/AGENTS.md | 3 ++- packages/opencode-auto-advisor/README.md | 6 +++--- .../opencode-auto-advisor/scripts/timeline.test.ts | 12 ++++++++++++ packages/opencode-auto-advisor/src/server.test.ts | 2 ++ packages/opencode-auto-advisor/src/telemetry.ts | 9 ++++++--- packages/opencode-auto-advisor/src/units.test.ts | 13 ++++++++++++- 7 files changed, 49 insertions(+), 9 deletions(-) diff --git a/docs/auto-advisor/findings.md b/docs/auto-advisor/findings.md index 9634f7d..1bff93c 100644 --- a/docs/auto-advisor/findings.md +++ b/docs/auto-advisor/findings.md @@ -41,7 +41,7 @@ Verified 2026-10-28 on `@opencode/cli@2.2.0` with an isolated HOME/XDG, a local - `active` with thresholds at 0 and real Jev: step 1 and step 2 each got a review at the tail of their own request; each review became a durable entry from the next step on; the budget stopped at 2.
