fix(harvest): run the semantic harvest on the shared stop path by ooples · Pull Request #326 · ooples/token-optimizer-mcp

ooples · 2026-08-26T20:43:21Z

Closes #322.

#300 unregistered plugin/hooks/stop-harvest.mjs and nothing replaced it, so four capabilities went silently: the transcript archive, the harvest worker spawn, refusal detection, and the notice that says why no findings exist. On a full session with a valid credential, harvestMode() reports remote, the user has consented by not opting out, and nothing happens.

The issue understates it, and the correction changes the fix

It says the other ten adapter clients are unaffected because they reach the harvest through the shared adapter path. They do not. grep finds exactly one spawner of harvest-worker.mjs in the repository, and it is the unregistered file:

plugin/hooks/stop-harvest.mjs:318:  const worker = join(HERE, 'harvest-worker.mjs');

Every client routes Stop to its own generated entry, which routes to the adapter, and the adapter's stop branch only ever built the in-band prompt asking the model to call wiki_write — the very thing the design says the out-of-band harvest exists to avoid, since it makes the session pay for summarising itself. So the out-of-band harvest was dead on all eleven clients, not one. Qwen's Stop entry is even named token-optimizer-semantic-harvest.

The archive is dead on master too, not restored — archive() has exactly one caller and it is the same unregistered file.

The fix

Moved to the shared core rather than re-registered on one client. stop-harvest.mjs becomes hooks-core/stop-harvest.mjs, exporting runStopHarvest(payload), and the adapter's stop branch awaits it. Fixing only Claude Code would have left ten clients with the same dead feature.

And the worker moved with it — the part that made a shared fix possible at all. harvest-worker.mjs lived in plugin/hooks/, which is vendored to no other client, so even a correctly registered Stop on the other ten would have found no worker to spawn. It now sits in the core every client receives an identical copy of, and the adapter resolves it as a sibling. A test asserts that per client rather than trusting the sync script to have run.

The notice is returned, not written. The old hook wrote its own JSON to stdout beside whatever the hook emitted; two writers on one hook's stdout is how a Stop payload gets corrupted. The adapter folds it into the single object it emits, so the one line explaining why no findings exist can no longer be dropped by a full pipe or truncated by an exit — which is exactly what used to happen to it.

Nothing about the harvest's behaviour changes: it is still debounced, still spawns detached so Stop is never delayed by a model call, and the archive and refusal detection still run outside the paid opt-in, because they are local file reads that cost no model call and send nothing anywhere.

Why it survived a year

Nothing observed that the harvest had not run. There is no kind:'harvest' event to be absent from a report, no error, and a harvest that ran and found nothing looks exactly like one that never started.

The reachability guard could not see it either — and that is worth stating plainly, because #323 shipped that guard and documented this exact limitation. The unregistered file's own imports gave archive, detectRefusals and recordRefusal their call sites. A name-based scan proves a reference exists, never that it runs. The existing marker suite even went on passing, because it spawned the removed hook directly; it now drives the registered entry, so it fails if the harvest becomes unreachable again.

Verification

Nine assertions in tests/hooks/stop-reaches-the-harvest.test.mjs, every one through the file the host is actually configured to run. Both defects mutation-tested:

Mutation	Result
Unwire `runStopHarvest` from the adapter	4 of 9 fail
Delete `Stop` from `hooks.json` (the #300 defect itself)	1 fails

221 suites, 2706 tests, 5 skipped, 0 failed. tsc --noEmit clean, npm run lint 0 errors, format:check clean, sync:hooks:check in sync across eleven vendored directories, validate passes. Quality Gates run locally: verify:clients, verify:certification, verify:harvest, verify:live-graph, verify:ui 55/55, verify:interactions 64/64.

Note for Plan 2 (#320)

Its Task 5 covers "run derive at Stop", and its own notes say the transcript archive was restored there. This lands in the same place — hooks-core's Stop path — and restores the archive for every client, so that part of Task 5 should be dropped rather than merged twice. The in-band wiki_write prompt is untouched, and derive.mjs still has a clean seam to hook into beside runStopHarvest.

Summary by CodeRabbit

New Features
- Added automatic transcript archiving and background harvesting when sessions stop.
- Harvested findings and feedback are processed and saved for future use.
- Added refusal detection and recording from session feedback.
- Stop messages now display notices when harvesting is disabled or unavailable.
Bug Fixes
- Stop handling remains reliable when harvesting encounters errors.
- Prevented duplicate harvests within the same session.
- Improved session and project context handling across integrations.

Walkthrough

Stop hooks now call runStopHarvest, archive transcripts, detect refusals, return disabled-state notices, and start detached workers. Workers extract validated findings and feedback lessons. Client adapters include notices in stop responses. Tests verify registered hook routing and shared worker placement.

Changes

Stop-time semantic harvest

Layer / File(s)	Summary
Shared harvest contract `hooks-core/adapter.mjs`, `hooks-core/stop-harvest.mjs`, `hooks-core/harvest-worker.mjs`	The shared Stop harvest now accepts payloads directly, returns notices, and resolves worker dependencies from the shared core.
Stop adapter lifecycle `/stop-harvest.mjs`, `/adapter.mjs`	Stop adapters normalize session data, archive transcripts, record refusals, debounce harvests, protect marker files, report disabled states, and spawn detached workers.
Detached worker pipeline `*/harvest-worker.mjs`	Workers validate and consolidate findings, persist feedback lessons, record metrics, preserve exit codes, and use a five-second watchdog.
Client adapter wiring `*/adapter.mjs`	Client adapters run harvesting fail-open and include returned notices as `systemMessage` in follow-up or decision responses.
Registered hook validation `tests/hooks/*`, `tests/unit/stop-harvest-markers.test.ts`, `scripts/sync-hook-core.mjs`	Tests verify registered Stop routing, transcript archiving, single-use notices, worker locations, generated banners, and hashbang placement.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to d00c7

The shared Stop path now returns a harvest notice, but a forced process exit can still prevent that notice from reaching users in piped integrations. The PR should not merge until this response-delivery risk is fixed or explicitly accepted.

Poem

A rabbit watched the Stop hook run,

Transcripts tucked away from sun.
Findings hopped through graphs in flight,
Markers guarded paths at night.
“Detach,” she cheered, “then close with grace!”
The harvest left a tidy trace.

49-62: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

OFF_REASON no longer matches harvestMode().

harvestMode() in integrations/opencode/hooks/lib/harvest.mjs (lines 78-118) returns off:mode, off:opted-out, local, remote, or off:no-key. It never returns off:not-opted-in. That entry is therefore unreachable, and its text still describes harvest as opt-in, which contradicts the on-by-default policy documented in harvestMode(). The module header at lines 19-24 carries the same stale claim.

off:opted-out maps to undefined, so an opted-out user receives no notice. That behavior looks intended. Replace the dead key with the real states, or document that off:opted-out is deliberately silent. Apply the change in hooks-core/stop-harvest.mjs and re-sync.

The refusal pass runs on every Stop with no debounce.

load(shared) reads the whole shared graph, and readFileSync(transcript, 'utf8') reads the whole cumulative transcript. Stop fires at the end of every assistant turn, and this block sits above the dueForHarvest debounce at line 337. On a long session the transcript grows to megabytes, so each turn pays a full re-read and a full graph parse synchronously on the Stop path that lines 14-17 promise is never delayed.

Consider gating this pass on the same interval marker used by dueForHarvest, or on a transcript byte offset already processed. Apply the change in hooks-core/stop-harvest.mjs and re-sync.

…top payload Four review findings, all valid. One was critical and would have shipped this pull request as a no-op. THE HASHBANG. `sync-hook-core` prepends its GENERATED banner, which pushed harvest-worker's `#!/usr/bin/env node` to line 3 -- and Node accepts a hashbang only at byte zero. Every vendored copy was a SYNTAX ERROR. The worker is spawned detached with stdio ignored, so it would have failed instantly and silently: the harvest still not running, for exactly the reason it was not running before, with a green suite on either side of it. Verified with `node --check` on the generated file before the fix. Fixed in the generator rather than by deleting the hashbang, because the next executable added to the core would hit it again and the failure mode is invisible by construction. `withBanner` keeps a leading hashbang on line one and puts the banner after it. AND THE ASSERTION WHOSE ABSENCE ALLOWED IT. This branch's own test checked that the vendored worker EXISTS -- and it said so while every copy was unparseable. Existence is not executability, which is this pull request's whole point applied to its own output. Every vendored core file is now `node --check`ed in three client directories, and the hashbang property is pinned separately. Mutation-tested: restoring banner-before-hashbang fails both. THE STOP PAYLOAD. The adapter resolves `sessionId` and `cwd` through every alias a host might use -- `sessionId`, `conversation_id`, `working_directory` -- and then handed `raw` to `runStopHarvest`, which reads `session_id` and `cwd` only. On a client sending an alias the session id came back undefined and the archive root fell back to `process.cwd()`: the once-per-session notice and the debounce marker shared across every session, and transcripts filed under whatever directory the hook happened to start in. A normalised payload is passed now, and `cwd` is hoisted out of the try block below so both halves of the hook reason about one resolved directory. THE SPAWN. `spawn` reports a failed start through an asynchronous `error` event, and an unlistened one is raised rather than returned -- which would abort the Stop response itself. A harvest that cannot start must degrade to no harvest, never to a broken Stop. `child.on('error', () => {})` after unref. 221 suites, 2708 tests, 0 failed. tsc, eslint, prettier, sync:hooks:check and validate clean; all six verify gates pass.

- Around line 225-226: Update the assertion in the stop-reaches-the-harvest test
to verify that the second line of vendored contains the generated-file banner,
rather than merely checking that the text appears somewhere. Preserve the
expected hashbang on the first line and enforce the documented
hashbang-and-banner layout.
- Around line 200-204: Update the tests in stop-reaches-the-harvest to define
one shared list containing every supported vendored lib directory, including
those currently used by the syntax and hashbang checks, then reuse that list in
both tests so every client copy is validated consistently.

Included review availability: Your plan provides up to 2 included reviews per hour; 0 remain after this review.

Two review findings, both about the guard this branch added rather than the code it guards. PARTIAL COVERAGE READ AS COVERAGE. The parse check looked at three of the eleven vendored directories and the hashbang check at two, so a broken generated file in any other client stayed invisible -- which is the same silence the guard was written to break. The directories are now DISCOVERED rather than listed: any directory named `lib` holding an `adapter.mjs` is a vendored core by construction, so a twelfth client is covered the day it is added rather than the day somebody remembers. A floor of eleven guards a walk that finds nothing, which would pass every assertion below forever. Widening it needed it to get faster, not slower. Spawning `node --check` per file cost 7.5s for three directories and would have cost half a minute for eleven; `vm.SourceTextModule` performs the same parse in process, without evaluating, and covers all eleven in 300ms. THE BANNER ASSERTION WAS `toContain`, which passes wherever the banner happens to land in the file -- including below the hashbang, which is the exact layout the test exists to reject. It now asserts the second line. Trimmed per line, because the vendored copies carry CRLF on Windows and the assertion is about which line the banner is on rather than about endings. Mutation-tested against a client the previous version never looked at: moving the hashbang to line three in integrations/kilo fails both checks, and displacing the banner in integrations/windsurf fails the layout one. 223 suites, 2737 tests, 0 failed. tsc, eslint, prettier and sync:hooks:check clean.
