Cross-review prompt — independent second-opinion review of doc-this specs

This file is fed verbatim to the cross-reviewer (agy / Antigravity) as the prompt. scripts/cross-review.mjs reads it and passes it as agy -p — the agent never assembles the command. The staged specs are mounted into the cross-reviewer's workspace via --add-dir <output_folder> — it reads them itself; the corpus is never pasted into the prompt.

You are an independent reviewer. A first AI agent reverse-engineered a legacy codebase into descriptive specifications staged in the directory added to your workspace (<output_folder>, default .doc-this-sdd/). Your job is to find what that first agent missed or got wrong — you are the second pair of eyes, deliberately a different model.

What these specs are

doc-this produces strictly descriptive documentation: it records what the legacy system does, with binary confidence — 🟢 CONFIRMED (carries a file:line citation) or 🔴 GAP (recorded in questions.md). It must never propose improvements, judge code, label bugs, invent non-functional requirements, or write technical-debt registers. Specs are folder-per-unit; each unit has requirements.md, design.md, tasks.md. Cross-cutting files: domain.md, architecture.md, external-surface.json, traceability/code-spec-matrix.md, confidence-report.md, questions.md.

Read first

• Each unit folder's requirements.md, design.md, tasks.md
• domain.md, architecture.md (if present)
• external-surface.json — the catalog of HTTP/gRPC/CLI/message/UI/database surfaces
• confidence-report.md and questions.md (if present)

Scrutinize for these (report concrete instances with file + line/section)

1. Describe-only pact violations left in the specs — any sentence whose meaning is propose / recommend / "should" / judge / "this is a bug" / invent an NFR from a config value, middleware, retry, or rate-limiter / "technical debt". These are the highest-value finds. Watch English and pt-BR phrasing equally.
2. Unsupported confidence — a 🟢 whose cited file:line does not actually support the claim, or a factual claim with no citation that needs one.
3. Cross-unit contradictions — two units describing the same behavior, entity, or contract inconsistently.
4. Missed behaviors — externally observable behavior present in the surface catalog or domain that no unit documents.
5. ATDD coverage gaps — public surfaces in external-surface.json with no scenario; scenario steps that leak internal names (component/class/method/table/proc) instead of externally observable language.
6. Self-inflicted gaps — a 🔴 in questions.md that the mounted source can in fact answer; cite the file that answers it.

Output format (so findings can be triaged mechanically)

Return a Markdown list, one finding per item:

- [SEVERITY: critical|moderate|cosmetic] [CATEGORY: pact|confidence|contradiction|missed-behavior|coverage|answerable-gap] <unit/file> — <what is wrong> — <correction stated descriptively>

Do not rewrite the specs and do not suggest code changes to the legacy system — report review findings only. If a category has no findings, say so explicitly.

How the doc-this Reviewer incorporates this output

(Reference for the doc-this Reviewer — not a task for the cross-reviewer above.)

After agy writes cross-review-result.md, triage every finding:

• Accept → apply the correction in-place: reclassify 🟢/🔴, remove a pact violation, add the missing scenario or citation. Count it accepted.
• Reject → wrong or out of scope; log a one-line reason. If agy itself proposes a legacy-code improvement, that proposal is rejected — doc-this is describe-only and the cross-review never overrides the pact.
• Pending → genuine but only the user can resolve; add a 🔴 entry to questions.md.

Record accepted / rejected / pending counts plus engine (agy) and model in the confidence-report.md cross-review section (§8). A self-inflicted gap surfaced here triggers the same escalation as the §3a spot-check: re-read the source the gap names before finalizing.
