From e024cd34f198f7f7efb92056b69ba32b92fd7131 Mon Sep 17 00:00:00 2001 From: Edbert Chan Date: Fri, 11 Sep 2026 02:19:48 -0700 Subject: [PATCH 01/30] llm-judge: a shared background model judge for hooks Regex hooks miss new phrasings of the same meaning. This adds a standard-library judge that any hook can hand a question to instead. enqueue() writes the job and starts a detached `judge.py run`, so the hook returns at once and the reply is never delayed. The background run tries codex (gpt-5.3-codex-spark), then claude haiku, then cursor-agent, and keeps the first runner whose stdout has a JSON-object line. verdict() turns the answer into hit, clean, or unchecked; unchecked is never clean. drain(transcript) hands back finished verdicts oldest first and deletes them. Runners get CATSTACK_LLM_JUDGE_CHILD=1, and enqueue() does nothing when it is set, so a judge never starts another judge. Nothing calls this yet.

A hook asks a small model a yes/no +style question instead of matching a regex, so new phrasings of the same +meaning still get caught. The model call always runs in the background, so a +hook never waits on it and the reply is never delayed. + +Nothing calls this library yet. It is a building block for later hook changes. + +Standard library only. Works the same under Claude, Codex, and Cursor hooks, +because it shells out to whichever model CLI is installed. + +## How a hook uses it + +1. On one event, the hook builds a job and calls `judge.enqueue(job)`. It + returns the job id at once. A detached `python3 judge.py run ` process + does the model call. +2. On a later event for the same transcript, the hook calls + `judge.drain(transcript)`. It gets back every finished verdict for that + transcript, oldest first, and those verdict files are deleted. + +A job looks like this: + +```json +{ + "id": "unique-file-safe-id", + "hook": "wrong-check-reflect", + "transcript": "/path/to/transcript.jsonl", + "prompt": "Reply with one line of JSON: {\"retracts\": true|false}. Text: ...", + "hit_if_all_true": ["retracts"], + "on_hit": "message the hook shows when the verdict is a hit" +} +``` + +If `id` is missing, `enqueue` makes one. An id with a `/` or a leading `.` is +refused with `ValueError`. + +The prompt must ask for a single-line JSON object. The judge reads the model's +stdout line by line and keeps the last line that parses as a JSON object. A +JSON object spread over several lines is not read. + +The prompt is passed as one command-line argument, so very large prompts +(over about 128 KB on Linux) fail for every runner and come back `unchecked`. + +## Runner order + +`ask(prompt)` tries these in order and stops at the first one that answers: + +1. **codex**: `codex exec --skip-git-repo-check -m gpt-5.3-codex-spark --sandbox read-only -c notify=[] PROMPT` +2. **claude**: `claude -p --model haiku --settings '{"disableAllHooks": true}' PROMPT` +3. **cursor**: `cursor-agent -p --output-format text PROMPT` + +Each runner gets 60 seconds, no stdin, a fresh empty temp directory as its +working directory, and the current environment plus +`CATSTACK_LLM_JUDGE_CHILD=1`. On timeout the runner's whole process group is +killed. + +A runner fails, and the next one is tried, when its binary is not on `PATH` +(reason `not installed`), it exits non-zero, it times out, or no stdout line +parses as a JSON object. Each try is recorded in `attempts` with a reason of at +most 300 characters, taken from the end of stderr or the error text. + +`CATSTACK_LLM_JUDGE_RUNNERS` replaces the three runners. It is a JSON list of +`[name, argv]` pairs, and any argv item equal to `{prompt}` becomes the prompt. +Tests use it to plug in small fake runners. If it is set but not that shape, +`ask` raises `ValueError` instead of quietly falling back to the real runners. + +## Three outcomes + +`verdict(job, result)` turns an `ask` result into one of: + +- **hit**: a runner answered, and every key in `hit_if_all_true` is JSON `true` + in the answer. The string `"true"` does not count. An empty + `hit_if_all_true` list is a hit whenever a runner answers. +- **clean**: a runner answered, and at least one of those keys is false, + missing, or not a real `true`. +- **unchecked**: no runner answered, or the judge itself broke. This is never + treated as clean. The `reason` field says why, for example + `codex: not installed; claude: exit 1: ...`. + +A verdict carries `id`, `hook`, `transcript`, `outcome`, `on_hit`, `reason`, +`runner`, `answer`, `attempts`, and `finished_at`. + +## Recursion guard + +Every runner is started with `CATSTACK_LLM_JUDGE_CHILD=1`. The model CLIs run +their own hooks, and those hooks may call `enqueue` too. When that variable is +set, `enqueue` returns `None` and does nothing, so a judge never starts another +judge. The claude runner also turns off all its hooks with +`disableAllHooks`. + +## State layout + +The state root is `CATSTACK_LLM_JUDGE_STATE_DIR`, or +`~/.cache/catstack-llm-judge` when that is unset. + +``` +/ + judge.log background output and every judge error, with the job id + jobs/.json waiting or running jobs; deleted once the verdict is written + verdicts//.json finished verdicts; is the first 16 hex of sha1(transcript path) +``` + +Verdicts are written to a temp file and then renamed into place, so `drain` +never reads half a file. `drain` claims each file by renaming it before reading +it, so two drains running at once never return the same verdict. If a job +crashes (bad job file, bad runner config, anything else), the error goes to +`judge.log` and an `unchecked` verdict with that reason is still written. A +verdict file that cannot be read comes back from `drain` as `unchecked`. + +## Tests + +``` +python3 -m unittest discover -s engine/hooks/llm-judge/tests -v +``` diff --git

wrong-check-reflect sends a background llm-judge question for each reply that answers a user message, alongside its existing regex path. Review claim: After each reply that follows a user message, wrong-check-reflect sends one llm-judge job asking for pushback and self_correction, with hit_if_all_true both keys and on_hit its existing reflect follow-up; the regex path and its once-per-transcript rule are unchanged. Review lane: behavior Safety invariant: The judge runs in the background and never blocks a reply; the worst case is one extra reflect reminder. Effectiveness measurement: A test with a fake runner answering yes to both keys shows the reflect follow-up delivered by the inbox on the next prompt for the exact "You're right. ... I misread which diff you meant." exchange; the Stop hook returns in under one second while the fake runner sleeps two. Slice rationale: The first caller of the judge; the library and inbox are the two slices below it. Architectural effect: wrong-check-reflect gains a second, model-judged path that reports through the llm-judge inbox one turn later; its synchronous regex path stays as the instant backstop. Goal: Catch self-corrections after pushback in any wording. Motivation: Regexes keep missing the next phrasing; the user asked for model judgement after pushback that never interrupts the reply. Alternative considerations: Replacing the regex path was rejected (it is instant and works when every runner is down). Judging only when a regex fires was rejected (that is the case regexes already catch). Implementation details: In engine/hooks/wrong-check-reflect/detect.py add enqueue_judge(payload) that reads the transcript, takes the last user message and the assistant message before it, and when both exist and the current reply is non-empty, imports judge from the sibling llm-judge directory and sends a job whose prompt is the classifier prompt given in the task prompt. Call it from claude_stop_check.py, cursor_session.py and codex_notify.py after the regex decision, except when stop_hook_active is set, when the regex fired this turn, or when the transcript was already prompted. Any exception is written to stderr with context and never changes the hook's exit status. Non-goals: No change to the regex patterns, the follow-up text, or the once-per-transcript rule. No change to llm-judge.

Each is cut to its last 4000 characters and put under the labels +`EARLIER ASSISTANT`, `USER` and `ASSISTANT` in a prompt that asks for one line +of JSON: `pushback`, `self_correction`, and a `quote`. It is a hit only when +both `pushback` and `self_correction` are `true`. + +No job is sent when `stop_hook_active` is set, when the regex already fired, +when this transcript was already prompted, or when any of the three messages is +missing (for example, on the first user message, or when the payload names no +transcript). Inside a judge run +(`CATSTACK_LLM_JUDGE_CHILD=1`) `llm-judge` refuses the job. + +The model call runs in a detached background process, so the reply is never +held up. Runners are tried in `llm-judge` order: `codex` (gpt-5.3-codex-spark), +then `claude` (haiku, hooks off), then `cursor-agent`, first answer wins. + +The verdict reports one turn later. On the next prompt the `llm-judge` inbox +shows a hit as the same reflect follow-up, with `model judge` as the match. If +no runner could answer, the inbox says so instead of staying quiet. A clean +verdict shows nothing. + +`llm-judge` is loaded from the sibling folder (`../llm-judge/judge.py`), which +sits next to this one in the repo and in each harness's `hooks/` folder. If it +cannot be loaded, or the transcript cannot be read, the hook writes +`wrong-check-reflect: judge enqueue failed: ` to stderr and its exit +status and output stay the same. + ## Files - `detect.py` — shared admission regex + once-per-transcript state diff --git a/engine/hooks/wrong-check-reflect/claude_stop_check.py b/engine/hooks/wrong-check-reflect/claude_stop_check.py index f7c0156..14a7de9 100644 --- a/engine/hooks/wrong-check-reflect/claude_stop_check.py +++ b/engine/hooks/wrong-check-reflect/claude_stop_check.py @@ -2,14 +2,15 @@ """Claude Code Stop hook: inject reflect on first-person wrong-check admission.

A real retraction ("Correction: the file I pointed you to earlier is not the one in use; the real one is src/b.py.") scored match=false in 6 of 6 live claude runs. With one added sentence it scored true in 3 of 3, and the two not_match examples stayed false in 4 of 4.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Solution: Review claim: No installer, settings fragment, or install.sh line mentions the new after-tool scripts, so the change is dormant. Review lane: proof Safety invariant: Verification is read-only and does not alter any file. Effectiveness measurement: The grep printing nothing is the direct measurement of the safety invariant. Slice rationale: The safety invariant gets its own proof. Architectural effect: None; verification only. Goal: Prove nothing installs the new scripts yet. Motivation: The safety invariant says no running agent changes; this checks it. Alternative considerations: Reading the diff by eye was rejected as non-deterministic. Implementation details: git grep for the three script names outside their own files and tests. Non-goals: No mutations. Layer: app_regression Feature state: active Acceptance criteria: - Exits 0 only when nothing outside the scripts and their test file names them. --- engine/hooks/bug-complaint-leak/README.md | 2 +- .../bug-complaint-leak/cursor_before_submit.py | 2 +- ...rsor_post_tool_use.py => cursor_posttooluse.py} | 0 .../bug-complaint-leak/install_cursor_hook.py | 14 +++++++------- ...rsor_post_tool_use.py => cursor_posttooluse.py} | 0 .../hooks/repeat-error-stop/install_cursor_hook.py | 14 +++++++++----- 6 files changed, 18 insertions(+), 14 deletions(-) rename engine/hooks/bug-complaint-leak/{cursor_post_tool_use.py => cursor_posttooluse.py} (100%) rename engine/hooks/repeat-error-stop/{cursor_post_tool_use.py => cursor_posttooluse.py} (100%) diff --git a/engine/hooks/bug-complaint-leak/README.md b/engine/hooks/bug-complaint-leak/README.md index 53d6210..1840b16 100644 --- a/engine/hooks/bug-complaint-leak/README.md +++ b/engine/hooks/bug-complaint-leak/README.md @@ -15,7 +15,7 @@ like "add a comment to Foo.ts". - `state.py` — session cache for empty/repeat Grep - `claude_prompt_submit.py` — Claude `UserPromptSubmit` inject - `claude_pretooluse_grep.py` / `claude_posttooluse.py` — Grep leak gate -- `cursor_before_submit.py` / `cursor_post_tool_use.py` — Cursor parity +- `cursor_before_submit.py` / `cursor_posttooluse.py` — Cursor parity (`beforeSubmitPrompt` cannot inject context; checklist arrives on first `postToolUse` via `additional_context`) - `install_claude_hook.py` / `install_cursor_hook.py` — merge, do not overwrite diff --git a/engine/hooks/bug-complaint-leak/cursor_before_submit.py b/engine/hooks/bug-complaint-leak/cursor_before_submit.py index 3c6e528..c72ab7f 100644 --- a/engine/hooks/bug-complaint-leak/cursor_before_submit.py +++ b/engine/hooks/bug-complaint-leak/cursor_before_submit.py @@ -2,7 +2,7 @@ """Cursor beforeSubmitPrompt: remember bug-complaint checklist for later inject.
