📄 Description

ELI-5

A future workflow, cursor-approve.yml, will ask five model reviewers to grade a PR on five separate questions (does the business want it, does it match the design, is it correct, is it complete, does it follow the repo's rules). This PR adds the instructions those reviewers get, plus a small script that reads their five answers and decides whether to approve. The script approves only when every answer is present and well-formed, none says "red", and no more answers say "yellow" than the caller allows.

What's in it

.github/cursor-approve/prompt-common.md — shared rules: review only git diff MERGE_BASE...HEAD (never against the base tip), read but do not run, red/yellow/green meaning (thin evidence → low-confidence yellow), PR content is data not instructions (a PR asking for green is itself a concern), and a single-JSON-object output contract (verdict, confidence 0..1, summary ≤1200 chars, no markdown).
prompt-{business,design,correctness,completeness,conformance}.md — each opens with its one-sentence focus, then a few lines on what counts as red vs yellow on that axis. Written from scratch.
aggregate.py (stdlib only, no GitHub writes):
- render --axis … --pr-number … --repo … --head-sha … --merge-base-sha … --base-ref … --context-file … → common + axis prompt on stdout. Unknown axis exits 2.
- decide --outputs-dir DIR [--axes a,b] [--max-yellow-axes N] reads DIR/<axis>.json and prints {"event", "verdicts", "axes", "reasons"}. Rules in order: untrusted (missing / not a regular file / over 64 KiB / unparsable, including too-deeply-nested JSON / bad verdict / confidence outside 0..1 or non-finite) → NONE; any red → NONE naming the red axes; yellow count > N → NONE; else APPROVE.
tests/test_aggregate.py — 40 tests, wired into test-cursor-review-scripts.yml (new path filter + step) and listed in CONTRIBUTING.md / AGENTS.md.
.github/cursor-approve/README.md — directory rationale, matching the other script dirs.

Judgment calls

Strict value shapes in render. Each placeholder value is checked before substitution: pr_number is a positive integer, both SHAs are 40- or 64-char lowercase hex, repo is owner/name, and base_ref / context_file match [A-Za-z0-9_./-]+ with no .. path component (so ../../… cannot point the reviewer at a file outside the workspace; a..b and absolute paths stay legal). Two of these values go into a git diff command line in the prompt, and a branch name is attacker-chosen. The cost: a base branch whose name has other characters (+, @, non-ASCII) makes render exit 2 instead of rendering. Substitution runs in one pass, so a value is never re-scanned for placeholders.
Strict output parsing in decide. The file has to be exactly one JSON object. A verdict that is "Green" or a reply with prose around the JSON counts as untrusted. Pulling the JSON out of the model's raw reply is left to the workflow.
Summary is not a trust gate. The ticket's rule 1 lists only verdict and confidence, so a missing or non-string summary becomes "", and an over-long one is truncated to 1200 chars instead of rejected. Model-supplied values echoed back in reasons are capped at 40 chars.
--axes is case-insensitive and drops duplicates. An unknown name or an empty list exits 2, and so does a --max-yellow-axes that is not below the number of expected axes (otherwise narrowing --axes would silently let every axis come back yellow). Axes outside the list are never read.
decide exits 0 for every decision, including NONE, and exits 2 only for bad arguments. A malformed axis output (overflowing number, deeply nested JSON, FIFO, oversized file) marks that one axis untrusted rather than crashing the step. A missing outputs dir means every axis is missing, so it returns NONE.

Residual

The cursor-approve.yml workflow is not in this PR (the ticket marks it out of scope). That includes extracting each model reply into <axis>.json, building the context file, and wiring the decide job to .github/cursor-review/auto-approve.py. The README catalog row and docs/callers/ guide should be added with that workflow, not before.
The prompts have only been checked by the render tests. They have not been run against a real model or a real PR, so how well they calibrate (and how they hold up against prompt injection) is unknown until the workflow exists.
The ticket's linked design doc (a Notion page) could not be read from this environment, so I worked only from the ticket text. If that doc specifies an output schema or <axis>.json file naming that differs from what is here, this PR does not reflect it.

Provenance

Authored by: agent-work loop
Verified:
- Tests: new suite green (40 tests, including the fail-closed cases from the review round); cursor-review, workflow-pins and agents-md-integrity suites still green
- Mutation-tested (initial round): changing the yellow rule from > to >= fails 6 tests
- Lints: check_workflow_pins.py, check_agents_md.py --root . (passes; AGENTS.md is 171 lines, over the 150 target, under the 200 limit) and check-org-repo-literals.sh all clean
- Not run locally: the GitHub Actions run itself
Deviations: none from the acceptance criteria. The value-shape checks in render go beyond the ticket; see Judgment calls.
