The UI surfaces that as "Opencode failed to send message with error: Step interrupted". Root causes fixed here: * Interrupt-shaped failures were never recognised. The filter only matched "interrupted by user" / a type containing "cancel", but v2 reports an interrupt as {type:"aborted", message:"Step interrupted"}, so the plugin recovered from its own abort forever. Added isAbortError() and made the plugin refuse to recover from any abort-shaped failure, its own or the user's. * "Is this abort mine?" was tracked with a transient boolean that the runtime resets before it delivers session.execution.interrupted asynchronously. Replaced with a selfAbortAt latch + TTL, and the idle handler no longer runs its heuristics on top of our own abort. * There was no single choke point for recovery injection: the stall watchdog, the intent/tool-loop nudges and the abort+resume escalation each called notifyAndPrompt directly, with no rate limit. Added injectOnce(), which all three paths now use, refusing injections inside our own abort window, into a busy-but-live session (a turn sent to a busy session supersedes its in-flight step), and more often than injectIntervalMs (15s). The abort+resume escalation takes its own lane, since swallowing its continue would leave a session interrupted with nothing to restart it. * The loop guard counted the plugin's own continues, so it escalated on its own output; and targetedRecovery recorded the same continue twice. The guard is now evaluated before recording. * getActiveSessions() returned [] because v2's plugin SessionDomain does not expose session.active, which made the subagent-wait guard permanently dead — a parent that went quiet while its child ran was declared stalled and interrupted. Falls back to busySessions(), derived from our own busy flags. * Interrupts are now hard-capped per window, since an interrupt persists an errored assistant message that the UI shows as a send failure. Also: * Added the missing liveness events (session.step.streamed, *.started, session.synthetic, session.tool.input.*) so a step that starts and then produces no tokens, or a long tool-input generation, is not mistaken for a stall. * Removed dead code: waitingOnSubagent (never set true, so its guard could never fire) and maxRecoveryRetries (read from options, never used). * Made this file buildable: it imported a runtime Plugin.define from "@opencode/plugin", which is not a dependency of this repo. Use a local identity helper instead; `tsc --noEmit` now exits 0 where it previously failed with 2 errors. * log() now prefers ctx.app.log, since plugin console output is not captured anywhere retrievable. Verified with tsc (exit 0), the existing test suite (578 passing, 0 failing) and a behavioral harness that asserts zero injections during healthy streaming, zero after a user stop, zero in response to the plugin's own abort events, and a working stall recovery path. --- .gitignore | 3 + src/v2/index.ts | 294 +++++++++++++++++++++++++++++++++++++++++++----- 2 files changed, 266 insertions(+), 31 deletions(-) diff --git a/.gitignore b/.gitignore index 9451024..7a54f87 100644 --- a/.gitignore +++ b/.gitignore @@ -2,3 +2,6 @@ node_modules/ dist/ .DS_Store *.log + +# v2 build output (bun build src/v2/index.ts --outdir dist-v2 --target bun) +dist-v2/ diff --git a/src/v2/index.ts b/src/v2/index.ts index cd9db64..8622ffb 100644 --- a/src/v2/index.ts +++ b/src/v2/index.ts @@ -32,7 +32,39 @@ * { "plugins": [{ "package": "./plugins/auto-resume-v2.ts", "options": { ... } }] } */ -import { Plugin } from "@opencode/plugin" +/** + * v2 entrypoint shape. + * + * The package depends on `@opencode-ai/plugin`, which exports `Plugin` only as a + * *type* — `(input, options?) => Promise`.

It tested `part.state.status === "pending"`, but the v2 message projection never writes "pending" — an in-flight tool part reads "running" and settles to "completed" or "error" (`pending` was the v1 spelling). With that branch unreachable, auto-resume injected a synthetic `continue` over an unanswered `question`, which surfaced as the tool call being interrupted / "Step interrupted". Reported in #33. A second, independent defect: markIdle() cleared `permissionPending` immediately before inspectOnIdle() consulted it. The `session.idle` case calls markIdle() and then inspectOnIdle(), so the flag was always false by the time the guard that honours it ran — dead on exactly the transition it exists for. `permission.replied` is now the only thing that clears it, plus a TTL stale-clear mirroring the compaction one, so a `permission.asked` whose reply never arrives cannot strand a session forever. Interactive tools (`question`, `permission`, `ask`, `confirm`) stand down unless they reached "completed" — a `question` that came back "error" was interrupted, not answered. Verified against the real v2 message shape: ctx.session.context() returns a plain array, and the tool-part states actually observed in a live session are completed / error / running, never pending. Tests: src/v2/index.stand-down.test.ts drives the real v2 seam (event.subscribe -> async iterable, session.synthetic). It includes a mandatory control asserting recovery DOES fire when nothing is pending, plus over-blocking controls (answered question, non-interactive tool erroring, permission asked-then-replied) so the fix cannot silently disable auto-resume. 7 of its 13 assertions fail against the previous code.

On a real v2 runtime no case matched, so a revert left the session's watch state — including any armed recovery — intact against turns that had just been rewound. Verified against the running opencode server: all three names are declared event schemas with live store handlers. - `session.revert.staged` is intermediate (the server sets a `revert` field there), so it only counts as activity and keeps the state. - `session.revert.cleared` and `session.revert.committed` are terminal (the server clears that field on both) and drop the state, matching the existing `session.deleted` behaviour.

The v1 side of the plugin is untouched here. The v2 port read 15 of v1's 31 options and silently ignored the other 16, so a v1 config ported to v2 quietly ran on defaults. Three changes close that: - All 31 v1 option names are now read. `maxRecoveryRetries` is accepted as a fallback for v2's `maxRetries`, so a v1 config needs no edits. - 8 of them are accepted but not applied, because the v2 feature they tune is not ported (no token read, no reachable todo state, no discovery sweep). They are listed as accepted-but-inert in the startup line and explained in docs/known-issues-v2.md rather than left to look like live behaviour. - Any option key this build does not know produces one warn line at startup. v1 dropped unknown keys silently, which is how the gap went unnoticed. busyStallStrategy is now complete rather than half-wired: "off" skips the stall and "abort" interrupts the wedged step before continuing, mirroring the v1 branch. Previously only "off" was handled, so "abort" silently behaved as "continue" while appearing in the recognised set. src/v2/index.options.test.ts covers all of the above behaviourally, with a control per group, plus a source contract that fails if the declared options type and the recognised set drift apart. 630 pass, 0 fail. Also mirrors two upstream changes the v2 build had not picked up: - e1b8374: targetedRecovery now counts an attempt only after the prompt is delivered, so a rejected send no longer burns a retry. - DEFAULT_ACTIVE_USER_WINDOW_MS 15 min -> 5 min, matching v1. build:v2 was missing from package.json, so dist/v2/ could not be rebuilt from this branch at all.

From c871c2956f262d12064d32d1cd455655c368f83d Mon Sep 17 00:00:00 2001 From: famewolf Date: Thu, 1 Oct 2026 14:44:36 -0400 Subject: [PATCH 14/57] feat(v2): sweep sessions on startup, and give the plugin a log file at all MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two features ported from v1, and one defect fixed that made the plugin unobservable. Session discovery. v1 swept session.list() on an interval and trusted a `status` field on each row. v2 has something better — session.active() is the server's own record of what is running — so the sweep seeds a watch for every existing session and adopts the running ones as busy. Without it, a turn that was already mid-flight when the plugin attached produced no `session.execution.started` for us to see, so the stall watchdog had nothing to inspect and a wedged session stayed wedged. Both calls are read defensively: the v2 plugin `session` domain is a narrowed Pick that omits `list` and `active`, so each falls back to the raw client, and a host that supplies neither degrades to the event-derived busy set rather than failing. `discoveryDelayMs` is live again as a result, so it leaves the accepted-but-inert list (7 remain, down from 8). Logging. v1 logged through `ctx.client.app.log({ body: {...} })`, a real endpoint that reached the opencode log file. v2 removed it — `ctx.app` is `{name, version, channel}`, there is no `app` group in the protocol, and a hosted plugin's console.log is not captured by OpenChamber. The v2 build was therefore completely silent: the deployed one had zero log lines, and its only startup line predated the current work by days. A running watchdog and a dead one were indistinguishable, which is exactly what made a stall look like "nothing happened". This build appends to `~/.local/state/opencode-v2/auto-resume.log` (override with the new `logFile` option or `AUTO_RESUME_LOG_FILE`), capped at 2 MB, every write best-effort so an unwritable directory can never break the watchdog. Console output is kept alongside it. src/v2/index.discovery.test.ts covers both API shapes with a control per group, the `{data}` envelope, malformed rows, a throwing list(), and teardown leaking no timers. The option tests now read the log file rather than a stubbed `ctx.app.log`, so they exercise the real sink. 639 pass, 0 fail.

Two v1 detectors for that case are ported onto the idle path. A done-claim with no work report in it. v2 gated the details prompt on a 400-character threshold, which cannot tell "Task done." from a real two-line summary: it over-nudged terse reports and let short real ones pass. It now uses v1's containsWorkDescription — a backticked or bare path with a dotted extension, or a report header (Changed / Verification / Tests run / Results / Commands run). Asking again after a genuine report loops forever (#26). A trailing 🎉. The model's own "finished" signal, so completion latches instead of being nudged over. Per-turn: a new turn re-opens the question, and a later idle with no new text does not re-derive it forever. That exposed a second defect in activeUserWindowMs. The default was lowered to 5 minutes to match e1b8374, but the implementation asked "is the newest message a user message?" instead of v1's "was any inbound user message inside the window?". At idle time the newest message is the assistant turn that just finished, so the option never applied and the plugin nudged straight over a user who was mid-conversation. It now walks back for the most recent user message. dbg() also goes to the log file now, for the same reason the rest of the logging does: debug output is exactly when you are working out what the plugin did, and console-only output in v2 reaches nobody. src/v2/index.premature-stop.test.ts, 17 tests: a control per group, plus the two halves of the length heuristic, one-nudge-per-turn, budget re-arm, maxRetries, latch survival, latch reset, the handoff and active-user guards, and the session.context() fallback. 656 pass, 0 fail. --- docs/known-issues-v2.md | 30 +++ src/v2/index.premature-stop.test.ts | 295 ++++++++++++++++++++++++++++ src/v2/index.ts | 105 +++++++++- 3 files changed, 422 insertions(+), 8 deletions(-) create mode 100644 src/v2/index.premature-stop.test.ts diff --git a/docs/known-issues-v2.md b/docs/known-issues-v2.md index 6236d08..bb4b42c 100644 --- a/docs/known-issues-v2.md +++ b/docs/known-issues-v2.md @@ -52,6 +52,13 @@ the fix is mte090's `e1b8374`, applied to the v2 code path.

The v2 port declared the option inert because there was nothing to compare against; there was, it just needed reading. Tokens: session.usage.updated carries the session's current usage. tokenTotalOf sums input + output + reasoning + cache.read + cache.write, which is exactly TokenUsage.total in the schema and exactly what v1 accumulated. The window: ctx.model.get(providerID, modelID) hands over Model.Info.limit directly, where v1 had to walk the raw provider list. Usable is limit.context - Math.min(20_000, limit.output) — v1's arithmetic, unchanged, so the same threshold means the same thing on both builds. Cached per model. Routing is v1's. A subagent, with subagentNativeCompactionEnabled, requests native compaction: v1 called session.summarize(), v2 spells it session.compact, and it is not on the plugin session Pick, so it goes through the same defensive lookup that carries discovery. A parent goes to magic-context's ctx-wrapup command, but only when magic-context is installed — its setup disables native compaction, so compacting here would double-compress. v1 detected that with config.get().plugin; v2 removed the config domain, so it now reads ctx.plugin.list() and matches both the plugin id and its source spec, which is what makes it work for a local path and a package target alike. Both paths are one-shot per turn and fail-safe: no limit, no token count, a user cancellation, or a signalled completion means no intervention. contextSaturationThreshold and subagentNativeCompactionEnabled are live, so they leave the accepted-but-inert list (5 remain, down from 8). 16 new tests with a control per group, covering both routings, both compaction transports, the package-spec and local-path magic-context shapes, the one-shot budget, the user interrupt guard, the reserve arithmetic, cache and reasoning in the total, the threshold as a fraction, and the missing-model and missing-inventory fallbacks. 672 pass, 0 fail. --- README.md | 5 +- docs/known-issues-v2.md | 35 +++- src/v2/index.saturation.test.ts | 350 ++++++++++++++++++++++++++++++++ src/v2/index.ts | 273 +++++++++++++++++++++++-- 4 files changed, 644 insertions(+), 19 deletions(-) create mode 100644 src/v2/index.saturation.test.ts diff --git a/README.md b/README.md index a82a74a..349b812 100644 --- a/README.md +++ b/README.md @@ -462,14 +462,13 @@ Defaults are the same on v1 and v2 unless a row says otherwise. | `readyToContinuePatterns` | `READY_TO_CONTINUE_PATTERNS` | Array of regex strings overriding the default ready-to-continue detection patterns (case-insensitive).

It is available. The judgment is on the message, not the event stream: walk back to the newest assistant message that HAS a finish reason. If it carried text, the session answered and there is nothing to recover. If it did not, and it generated at least silentDeadStreamMinTokens output tokens, the stream died mid-response. The walk skips messages with no finish reason on purpose — an intermediate tool-call step has none, and stopping there would report a dead stream for every session that used a tool. Two v2 specifics worth the record. The judge needs session.context(), every message since the last compaction, so the idle inspection now fetches it once and shares it across four checks — this port was fetching it three times. And before injecting the plugin asks the server whether the session is running again, not only its own event-derived flag: a provider quietly retrying looks identical from the event stream, and the recovery event may not have arrived by the time the turn ends.

The turn completes, the prose reads fine, and the work silently does not happen. v1 already caught this on the same pass as the text variant, and answered with a different prompt — the fix is different, because the model is not forgetting the tool mechanism, it is writing in the wrong channel. v2 had joined reasoning and text into one string, so the two were indistinguishable and only the text one was judged. AssistantContent tags reasoning and text distinctly, which makes this two reads instead of one filter. Three decisions worth naming: Reasoning is judged first. A message can carry both, and the reasoning one is the one that silently does nothing; reporting the text one would send the model off to fix the wrong thing. The budget is shared with the text variant. One phenomenon, two symptoms — two budgets would let the plugin spend twice the retries on a model that keeps doing it. The same code-block stripping applies. A fenced example of the call format, or an inline path in backticks, is not a real call. thinkingToolRecoveryPrompt is live, so accepted-but-inert is down to three: subagentWaitMs, toolTextCheckDelayMs, doneWithoutWorkPrompt. 7 new tests, with a control per behaviour including the two-channel precedence. 690 pass, 0 fail. One thing the tests surfaced and the fixtures had to respect: a message that finished with no text part at all is a silent dead stream, and that detector fires first.

The port declared doneWithoutWorkPrompt inert on that basis. There is another way in. v2 has a storage domain, and the installed todo tool already writes the list there under a stable per-session key — storage.set("todos/", { todos, updatedAt }). auto-resume reads that key instead of owning a list of its own, so it is a consumer rather than a second owner: it works with whichever todo tool is installed, and there is no copy to drift. It only ever calls get — asserted by a test that hands the harness a set and a remove and checks neither is called. Three things consume it. A trailing 🎉 is no longer trusted on its own: a model that finishes early celebrates early, and latching on that turns a false positive into permanent silence, so with items still open the celebration is treated as a false positive and the reminder names what is unfinished. That branch deliberately does not latch, so the next turn is free to judge again. doneWithoutWorkPrompt now fires for a done-claim with open todos, on a budget separate from doneClaimAttempts — two different problems, so spending one must not silence the other. And with no storage domain, or a record that will not parse, it falls back to "no list", which means the older behaviour and never a nudge on the strength of a list it failed to read. One fix came along with it. The done-claim budgets no longer reset on every busy cycle — only on a genuinely new inbound user message. v1 moved both out of the busy reset for #26: a model that re-announces completion each turn was otherwise handed a fresh budget each time it announced, so the nudge never stopped. v2 still had that.

The second of those is the part that makes it count: a model that finishes, reports, does more work and reports again is doing its job, not looping, and the escalation must not reject it. Two guards. The todo gate is skipped for subagents — a child was never asked to do the parent's open items, so gating its report on them blocks it on work outside its scope. And a blocked call fires a visible nudge naming the blocking todos, because the tool result can collapse to an invisible one-liner in the transcript; skipped when the user holds the ball, since injecting then starts a step their real reply interrupts. The block stays bounded by maxRetries, because an unbounded block is its own kind of loop. Registration failure — no ctx.tool, or a registry that throws — is logged and swallowed. It must not take down the session recovery the rest of this plugin exists for, so the watchdog starts either way. Two tests cover that.

The effective name is the namespaced form when a tool sits in a namespace, which is exactly the string a model would have to call, so that is what the suggestion quotes back. The parts come from the message history rather than from events, and that is not a workaround: the thing being looked for is a part that already errored, and by the time the error lands the session.tool.called event for that part is long gone. This code only runs on idle anyway. Two v2 shapes differ from v1, and both differences point the same way — inert rather than wrong, which is the failure mode that does not announce itself. v1 reads the tool name from part.tool, which v2 has no field for; the name is in part.name, and a port keeping v1's read would compare against "" and never fire. v1 keys its already-examined set on part.id ?? part.callID, and v2's tool part has id and name but no callID. The state.status === "error" test carries over unchanged, because error really is one of v2's four tool states. The check abstains rather than guesses. No registry, an empty registry, or a registry that throws all mean no suggestion, because with nothing to compare against every name looks invented — and telling a model that a tool it plainly just used does not exist is the one failure mode that teaches it the registry is unreliable. One ordering fix fell out of testing. The per-request re-arm is derived from the message history, so it cannot be applied before the history is read, but the already-suggested guard ran before that read while the check runs alongside inspectOnIdle, whose ordering is not defined. On a re-armed turn the guard could see the previous turn's latch still standing and skip the very check that was supposed to re-arm it.

Nothing is idle, nothing is busy in a way the ordinary watchdog questions, and every other path declines to act because the silence is shorter than chunkTimeoutMs. The watch is armed from session.idle, when the busy count drops from more than one to exactly one, and it runs ahead of the silence check for exactly that reason. v1's signal is kept; two of its conclusions are not, because v2 can check them. The survivor is asked whether it really has children. The busy-count drop alone is not evidence — two unrelated conversations open at once and one of them finishes looks identical to a parent whose child died, and v1 has no way to tell them apart, so it aborts the survivor either way. One session.list({ parentID }) at arm time turns a guess into a fact. The filter is requested *and* the returned rows are checked against it client-side: the only consequence of the filter being quietly ignored would be aborting real sessions. A child is judged on what it last did, not on whether the server still lists it. v1's check scans the global status map for a busy session and reports "idle" when it finds none — a reading that cannot work here, because this code is only ever reached after a child went idle, so a child being absent from the active set is the premise rather than the finding. Read that way every crashed subagent looks healthy, the child is never woken, and the parent is aborted on the first tick. So a child that said something inside the window is believed; one silent past the threshold with a tool call still outstanding gets a tripled window, because a five-minute build is not a dead model and killing the parent there loses the work; one silent past the threshold, or carrying an errored message, is worth a single attempt to wake. Waking the child is tried once per episode. v1's structure assumes the subagent goes busy again after the prompt, and a dead one never does, so an unbudgeted retry sends the same nudge on every watchdog tick. The sequence is: nudge once, wait a further subagentWaitMs, and abort the parent only if the child is still dead. v2 delivers the prompt through the plugin-scoped synthetic endpoint, which takes an explicit sessionID, so no cross-session route the plugin API does not expose is needed. In-flight tools are tracked from the tool lifecycle events — called increments, success and failed decrement — instead of a tool.execute.before hook, because v2 emits all three and the hook would be a second source of truth for the same fact. Both terminal events matter: a failed tool is finished work, and holding the slot on failure would make the watch defer on every session that has ever seen an error. A session that goes idle has its slots cleared, since a slot held there belongs to a tool that will never report. subagentWaitMs is the guard, and its default of 15s is what makes the abort tolerable: between a child finishing and the parent being interrupted, the parent is given that long to consume the child's result. A parent with a tool in flight is never interrupted, and neither is one waiting on the user.

That is the right +*signal* and the wrong *conclusion* on a busy box, and v2 can do better because +v2 records the parent link. + +**The port asks whether the survivor actually has children before arming.** One +`session.list({ parentID })` call at arm time turns a guess into a fact. v1 has no +way to ask — it treats *any other busy session* as a subagent of the one in hand +— so on a box with two conversations open it aborts one of them when the other +finishes. The `parentID` filter is requested *and* the returned rows are checked +against it client-side, because the only consequence of the filter being quietly +ignored would be aborting real sessions. + +**A child is judged on what it last did, not on whether the server still lists +it.** v1's `checkSubagentStatus` scans the global status map for a *busy* +session and reports "idle" when it finds none. That reading cannot work here: +this function is only ever reached *after* a child went idle, so a child being +absent from the active set is the premise rather than the finding. Read that way, +every crashed subagent looks healthy, the child is never woken, and the parent is +aborted on the first tick. So the three cases are: + +- **recent** — whatever the server thinks, the child said something inside the + window, so believe it. If it is also active, keep waiting. +- **silent past the threshold, tool call outstanding** — a long build, not a + dead model. The window is tripled, and the parent is left alone. Killing the + parent there loses the work. +- **silent past the threshold, or an errored message** — it stopped without + reporting. Worth one attempt to wake it. + +**Waking the child is tried once per episode.** v1's structure assumes the subagent +goes busy again after the prompt; a dead one never does, so an unbudgeted +retry sends the same nudge on every watchdog tick. The sequence is: nudge once, +wait a further `subagentWaitMs`, and abort the parent only if the child is still +dead. v1 sends the prompt through the client route; v2 uses the plugin-scoped +`synthetic` endpoint, which takes an explicit `sessionID` and so needs no +cross-session route the plugin API does not expose. + +**In-flight tools are tracked from the tool lifecycle events** — `tool.called` +increments, `tool.success` and `tool.failed` decrement — rather than from a +`tool.execute.before` hook, because v2 emits all three and the hooks would be a +second source of truth for the same fact. Both terminal events matter: a *failed* +tool is finished work, and holding the slot on failure would make the watch defer +on every session that has ever seen an error. A session that goes idle has its +slots cleared, since a slot still held there belongs to a tool that will never +report. + +### What still bounds the risk + +`subagentWaitMs` is the guard. Between a child finishing and the parent being +aborted, the parent is given this long to consume the child's result — the +default is 15s. v1's logic aborts as soon as no subagent is active, and so does +this; the option is what makes that survivable, and its name is the warning. Set +it small and the watch becomes a blunt instrument. Lower it only if you have +watched a parent wait minutes on a dead child. + +Two further guards, both checked before anything is interrupted: a parent with a +tool in flight is never aborted, and neither is one whose newest message is +waiting on the user. + +A give-up path bounds the whole thing: after `maxRetries` episodes the watch +disarms and logs it, rather than retrying a parent that has already survived +several aborts. + + ## Unknown tool names v1 asks `ctx.client.tool.ids()` for the registered tool names. v2 has no such diff --git a/src/v2/index.options.test.ts b/src/v2/index.options.test.ts index e1d7343..3f5c0de 100644 --- a/src/v2/index.options.test.ts +++ b/src/v2/index.options.test.ts @@ -291,11 +291,11 @@ describe("v2: option reporting at startup", () => { }) test("the startup line names the accepted-but-inert options in use", async () => { - const { logs } = await replay([], { chunkTimeoutMs: 5000, subagentWaitMs: 15_000 }) + const { logs } = await replay([], { chunkTimeoutMs: 5000, toolTextCheckDelayMs: 3000 }) const ready = logs.filter((l) => l.includes("ready (opencode v2)")) expect(ready).toHaveLength(1) expect(ready[0]).toContain("accepted-but-inert=") - expect(ready[0]).toContain("subagentWaitMs") + expect(ready[0]).toContain("toolTextCheckDelayMs") }) test("discoveryDelayMs is live on v2, so it is no longer listed as inert", async () => { @@ -304,15 +304,30 @@ describe("v2: option reporting at startup", () => { const { logs } = await replay([], { chunkTimeoutMs: 5000, discoveryDelayMs: 5_000, - subagentWaitMs: 15_000, + toolTextCheckDelayMs: 3000, }) const ready = logs.filter((l) => l.includes("ready (opencode v2)")) expect(ready).toHaveLength(1) expect(ready[0]).toContain("accepted-but-inert=") - expect(ready[0]).toContain("subagentWaitMs") + expect(ready[0]).toContain("toolTextCheckDelayMs") expect(ready[0]).not.toContain("discoveryDelayMs") }) + test("subagentWaitMs is live on v2, so it is no longer listed as inert", async () => { + // The orphan watch reads this option, so a config carrying it must not be told + // it is being ignored — that warning is the only way a user finds out. + const { logs } = await replay([], { + chunkTimeoutMs: 5000, + subagentWaitMs: 15_000, + toolTextCheckDelayMs: 3000, + }) + const ready = logs.filter((l) => l.includes("ready (opencode v2)")) + expect(ready).toHaveLength(1) + expect(ready[0]).toContain("accepted-but-inert=") + expect(ready[0]).toContain("toolTextCheckDelayMs") + expect(ready[0]).not.toContain("subagentWaitMs") + }) + test("the startup line carries no accepted-but-inert list when none are set", async () => { const { logs } = await replay([], { chunkTimeoutMs: 5000 }) const ready = logs.filter((l) => l.includes("ready (opencode v2)")) diff --git a/src/v2/index.orphan.test.ts b/src/v2/index.orphan.test.ts new file mode 100644 index 0000000..d926d5f --- /dev/null +++ b/src/v2/index.orphan.test.ts @@ -0,0 +1,572 @@ +import { describe, test, expect } from "bun:test" +import { existsSync, readFileSync, rmSync } from "node:fs" +import { tmpdir } from "node:os" +import { join } from "node:path" +import plugin from "./index" + +const wait = (ms: number) => new Promise((r) => setTimeout(r, ms)) +const SID = "ses_parent" +const CHILD = "ses_child" + +let counter = 0 + +function makeEventStream() { + const queue: any[] = [] + const waiters: ((ev: any) => void)[] = [] + let closed = false + const stream = { + push(ev: any) { + if (waiters.length) waiters.shift()!(ev) + else queue.push(ev) + }, + close() { + closed = true + while (waiters.length) waiters.shift()!(null) + }, + subscribe: () => stream, + [Symbol.asyncIterator]() { + return { + next: () => + new Promise((resolve) => { + if (queue.length) return resolve({ value: queue.shift(), done: false }) + if (closed) return resolve({ value: undefined, done: true }) + waiters.push((ev) => + resolve(ev === null ?

It armed a timer for `toolTextCheckDelayMs` and ran the done/tool checks from there, and the option is that delay. The reason is a race, not a preference: `session.idle` can arrive while the assistant's closing text is still being written into the message history, so a check that reads too early sees a half-finished turn — missing the pattern it should have caught, or judging a turn that was not over. The v2 build judged on the idle event for most of its life, on the strength of the live delta buffer: the plugin sees text as it streams, so it usually has the final turn before `session.idle` arrives, which is more reliable than waiting rather than less. It does not remove the race. The buffer is empty when the plugin loads mid-turn, and the fallback in exactly that case is the history that may not have flushed. That is why this option was the last one still accepted and not applied. So the work splits in two, and the option tunes the half that needs it. The structural pass runs on the idle event: is this a dead stream, is it handing control back to the user, is the user already busy. None of those read the final text, and the first of them cannot wait — a stream that died before delivering any text is precisely the case where every pattern check has nothing to look at, so deferring it would only delay a recovery that is already certain. The pattern pass runs `toolTextCheckDelayMs` later and re-reads the history, which is the whole point: text that landed after the idle event is what it judges. It also re-runs the structural guards rather than trusting the first pass's verdict. Three seconds is long enough for the user to have replied, and a synthetic nudge fired through a real reply interrupts the step their reply started. This is the one place the split could have made things worse, because the guards are the reason a nudge is safe and the deferral is the reason they could be consulted too late. Three lifecycle details, because a timer that outlives what armed it is a new way to nudge a session that has moved on. A new turn cancels a pending pass: `markBusy` clears the timer, and the timer re-checks that the session is still idle, because a queued callback can outlive the turn that armed it. A second idle replaces the first rather than stacking — two passes on one turn would spend two attempts of one budget on one piece of text, and the second would be a nudge about a nudge. And stopping the plugin drops any pending pass, or a reload leaves a timer pointing at a session this build is no longer watching. `FEATURE_GATED_OPTIONS` is now empty: every option this build recognises is applied. The list is kept rather than deleted, because it is the only signal a user gets that an option is being ignored, and the next unported feature needs it more than this build does. With no production path left to it, the invariant is asserted on the source instead — a test fails if an option is added to the recognised set without being implemented, which is exactly how this build went from several inert options to none. 11 new tests. Every one is mutation-checked: removing the delay, the arming, the history re-read, either guard re-run, the cancel latch, the new-turn cancel or the cleanup turns the file red. 766 pass, 0 fail. --- README.md | 37 ++-- docs/known-issues-v2.md | 71 ++++++- src/v2/index.dead-stream.test.ts | 1 + src/v2/index.discovery.test.ts | 8 +- src/v2/index.open-shell.test.ts | 1 + src/v2/index.options.test.ts | 64 ++++--- src/v2/index.orphan.test.ts | 1 + src/v2/index.premature-stop.test.ts | 1 + src/v2/index.saturation.test.ts | 1 + src/v2/index.settle-delay.test.ts | 283 ++++++++++++++++++++++++++++ src/v2/index.stand-down.test.ts | 1 + src/v2/index.task-complete.test.ts | 1 + src/v2/index.thinking-tool.test.ts | 1 + src/v2/index.todo.test.ts | 1 + src/v2/index.ts | 90 ++++++++- src/v2/index.unknown-tool.test.ts | 1 + 16 files changed, 510 insertions(+), 53 deletions(-) create mode 100644 src/v2/index.settle-delay.test.ts diff --git a/README.md b/README.md index 40466ba..646c279 100644 --- a/README.md +++ b/README.md @@ -436,19 +436,35 @@ Disable via `"-auto-resume.v2"` in `plugins`. - **Migration notes (v1 → v2, stable validation):** [docs/v2/migration.md](docs/v2/migration.md) - **What the v2 port does and does not yet do:** [docs/known-issues-v2.md](docs/known-issues-v2.md) -The v2 build reads every option in the table below.

The buffer is empty when the plugin loads mid-turn, and the +fallback in that case is precisely the history that may not have flushed. + +So the work is split in two, and the option tunes the half that needs it: + +| Pass | When | What it decides | +|---|---|---| +| structural | on `session.idle` | dead stream, user hand-off, user recently active | +| pattern | `+` `toolTextCheckDelayMs` | celebration, tool-call-as-text, ready-to-continue, action intent, done-claim | + +The structural pass is immediate on purpose. A stream that died before delivering +any text is exactly the case where every pattern check has nothing to look at, so +waiting would only delay a recovery that is already certain. + +The pattern pass re-reads the history rather than reusing the first read, which +is the whole point: text that landed after the idle event is what it judges. It +also **re-runs the structural guards** instead of trusting the first pass's +verdict, because the wait is long enough for the user to have replied — and a +synthetic nudge sent over a real reply is the "Step interrupted" bug those guards +exist to prevent. + +Three lifecycle details, all covered by tests: + +- A **new turn cancels** a pending pass. `markBusy` clears the timer, and the + timer itself re-checks that the session is still idle: a queued callback can + outlive the turn that armed it. +- A **second idle replaces** the first rather than stacking a second judgement on + the same text. Two passes on one turn would spend two attempts of one budget on + one piece of text, and the second would be a nudge about a nudge. +- **Stopping the plugin drops** any pending pass. Otherwise a reload leaves a + timer pointing at a session this build is no longer watching, and it fires + minutes later against a history nobody is reading. + +### One difference worth naming + +v1's `checkForToolCallAsText` bundles every text-based detector behind this one +timer. v2's detectors were separate before the option was honoured, so the delay +applies to the pattern pass as a whole rather than to the tool-call-as-text check +specifically. Nothing is lost by it — every detector that reads the closing text +gets the settle window, which is what the delay was for. + ## Orphan parent recovery v1 detects the busy-count drop from more than one session to exactly one and diff --git a/src/v2/index.dead-stream.test.ts b/src/v2/index.dead-stream.test.ts index b3218e8..2efca04 100644 --- a/src/v2/index.dead-stream.test.ts +++ b/src/v2/index.dead-stream.test.ts @@ -97,6 +97,7 @@ const toolStep = () => ({ const OPTIONS = { chunkTimeoutMs: 600_000, + toolTextCheckDelayMs: 0, checkIntervalMs: 20, gracePeriodMs: 0, warmupMs: 0, diff --git a/src/v2/index.discovery.test.ts b/src/v2/index.discovery.test.ts index b129d75..6828c07 100644 --- a/src/v2/index.discovery.test.ts +++ b/src/v2/index.discovery.test.ts @@ -120,7 +120,7 @@ async function run( const ctx: any = { event: stream, - options: { warmupMs: 0, discoveryDelayMs: 20, logFile, ...opts }, + options: { warmupMs: 0, discoveryDelayMs: 20, toolTextCheckDelayMs: 0, logFile, ...opts }, session, } if (client) ctx.client = client @@ -177,7 +177,7 @@ describe("v2: session discovery sweep", () => { const rows = [{ id: "not-a-session" }, { id: 42 }, {}, null] const ctx: any = { event: stream, - options: { warmupMs: 0, discoveryDelayMs: 20, logFile }, + options: { warmupMs: 0, discoveryDelayMs: 20, toolTextCheckDelayMs: 0, logFile }, session: { context: async () => [], active: async () => ({}), @@ -197,7 +197,7 @@ describe("v2: session discovery sweep", () => { const stream = makeEventStream() const ctx: any = { event: stream, - options: { warmupMs: 0, discoveryDelayMs: 20, logFile }, + options: { warmupMs: 0, discoveryDelayMs: 20, toolTextCheckDelayMs: 0, logFile }, session: { context: async () => [], active: async () => ({ [RUNNING]: { type: "running" } }), @@ -217,7 +217,7 @@ describe("v2: session discovery sweep", () => { const ctx: any = { event: stream, // Tight watchdog so a leaked interval is visible inside the wait. - options: { warmupMs: 0, discoveryDelayMs: 20, checkIntervalMs: 20, chunkTimeoutMs: 10_000, logFile }, + options: { warmupMs: 0, discoveryDelayMs: 20, checkIntervalMs: 20, chunkTimeoutMs: 10_000, toolTextCheckDelayMs: 0, logFile }, session: { context: async () => [], active: async () => { diff --git a/src/v2/index.open-shell.test.ts b/src/v2/index.open-shell.test.ts index 5318abc..4eb8385 100644 --- a/src/v2/index.open-shell.test.ts +++ b/src/v2/index.open-shell.test.ts @@ -95,6 +95,7 @@ async function replay(events: any[], messages?: any[]): Promise { const ctx: any = { event: stream, app: { log: () => {} }, + options: { toolTextCheckDelayMs: 0 }, session: { context: async () => messages ??

This one does not. `src/v2/index.ts` imports only `node:fs`, `node:os` and `node:path`, and declares its own `{ id, setup }` helper, so the built artefact is a single self-contained file and a local-file install needs no install step at all. A user following the old guide was told to install a package the plugin never loads, and the troubleshooting table carried a row for a `Cannot find package '@opencode/plugin'` failure this build cannot produce. So: the install step is gone, the requirement that the package "must be resolvable by opencode" is gone, the impossible troubleshooting row is gone, and `@opencode/plugin` is now described where it still matters — as the types the source is checked against in `bunx tsc --noEmit`. Three more things in those two files had stopped being true: - `chunkTimeoutMs` was documented as 45000 in the config example, the options table and the expected startup banner. It has been 180000 on both builds since upstream `49957b2`; the port had made the same change independently. - The options table listed 14 of 33 options with nothing pointing at the rest. It now carries the ones that matter *on v2* — the settle delay, and the two v2-only options that exist because v2 removed a capability (`logFile`, since there is no server log sink, and `injectIntervalMs`) — and links the README for the full table. It also says the port reads and applies all 31 of v1's options, which is now true. - `docs/v2/migration.md` still claimed a 12-test suite. It is 13 files and 188 tests, and it now says what those tests are for: the two vacuous ones in the settle-delay file, and why every test in the port is mutation-checked. The README's v2 section gets the same correction, since it is the page most people read instead of the guide. --- README.md | 2 +- docs/v2/installing.md | 85 +++++++++++++++++++------------------------ docs/v2/migration.md | 70 ++++++++++++++++++++++++----------- 3 files changed, 86 insertions(+), 71 deletions(-) diff --git a/README.md b/README.md index 38ae453..0f74124 100644 --- a/README.md +++ b/README.md @@ -412,7 +412,7 @@ With options: ### OpenCode v2 (stable) -The v2 plugin uses the `Plugin.define` API with `ctx.event.subscribe()` (AsyncIterable) instead of the v1 hooks-object pattern, and targets the stable **`@opencode/plugin` 2.0.5** API (opencode v2.0.5+).

The real store is the session message log: every `todowrite` call is persisted as a tool part whose input carries the whole list, so the newest COMPLETED call is the current list. Read it via `ctx.client.session.message.list`, falling back to a loopback `GET /api/session/{id}/message?limit=200` — that endpoint answers `{data, cursor}`, never a bare array, and orders results newest first, so a last-match-wins parser selects the OLDEST list. Ranking is by timestamp, with encounter order as the tiebreak. `ctx.storage` is kept only as a last-resort fallback: in v2 that key is empty, not authoritative. This needs host access beyond the plugin context: `readFileSync` on `/proc/self/cmdline` for the local server's `--port`, plus a loopback GET.

That is false. A todo plugin does write that key, in its todowrite tool: ctx.storage.set(storageKey(sessionID), { todos, updatedAt }) The reason the read still cannot see it is that ctx.storage is namespaced per plugin, so the two writes land in different files. Verified against a live server on two independent surfaces: - the route carries the plugin id as a path segment: /api/plugin/storage// - the on-disk tree is storage/plugin//.json auto-resume asking for todos/ resolves to storage/plugin/auto-resume.v2/todos/.json; the todo plugin's write is under its own id. Cross-plugin visibility is impossible by construction, so the read misses regardless of who is writing - which is a stronger and more accurate reason to keep the message log primary than the one that was written down. This matters beyond wording: "nothing writes it" invites the fix "so let auto-resume write it too", which would be wrong twice over - a reader cannot surface another plugin's data by writing a key, and a second writer for one logical list races the first. Both the code comment and the docs now say so explicitly. Also records a measured detail the ranking depends on: the todowrite tool parts carry no state.time, so ranking has to fall back to the enclosing message's time.created. Under newest-first ordering that fallback is load-bearing, not cosmetic. Comment-only change.

OpenCode treats the message as completed and the session goes idle, so no error or stall path triggers. On idle, if the **newest** assistant message has a finish reason, zero text parts, **zero tool-call parts**, and at least `silentDeadStreamMinTokens` output tokens, the plugin sends a recovery prompt. A finished turn that issued tool calls is working, not silent — thinking models routinely end tool-working turns with no chatter text (2026-10-04: this fired twice into an active session before the exception existed).
