Subagent prompts

Fill the {placeholders} and send each prompt to its own fresh-context subagent. Fresh context is the point: the reviewer must not share the author's assumptions.

Lenses

Quick depth sends one finder with both intent and fit.

Finder prompt

You are reviewing a code change in the repository at {repo_root}. Lens: {lens} — {lens_question}

Intent of the change: {intent}
Review this diff ({mode}): run `{diff_cmd}` to see it. The base commit is {base}.
Project instructions (CLAUDE.md / REVIEW.md excerpts): {instructions}
Already reported, do not report again: {known_findings}
Skip these paths: {review_skip}

Read any file you need. Report only problems you can prove from the code: for each one give the
file and line, the code that shows it, and a concrete input or sequence that triggers it.
Do not report style, naming, formatting, missing comments, or anything a linter, type-checker
or compiler would catch. Do not suggest refactors. If a problem appears in several places,
report it once as a class and list every instance.
It is a good outcome to find nothing. Do not invent findings to have something to say.

Return JSON only:
{"findings": [{"class": "short bug class", "title": "one line", "path": "...", "line": 0,
  "symbol": "enclosing function or type", "instances": ["path:line", ...],
  "evidence": "code + trigger", "fix": "smallest fix", "severity_guess": "Important|Nit"}]}

Verifier prompt

You are verifying candidate review findings for the change at {repo_root}
(`{full_diff_cmd}`, base {base}, intent: {intent}).

For EACH candidate below, try to refute it. Read the code, follow the call paths, check whether
the trigger can actually happen, whether a caller or test already guards it, and whether the
behavior is intended by the stated intent. Then vote.

Also decide provenance: is the problem introduced by this change, or already present at the
base commit? Check with `git show {base}:<path>`.

Candidates:
{candidates_json}

Return JSON only:
{"votes": [{"index": 0, "real": true|false, "severity": "Important|Nit",
  "provenance": "introduced|pre-existing", "reason": "one or two sentences with file:line"}]}

Keep a finding if it reaches the vote threshold for the depth (1/1, 2/2, ≥2/3). Its severity is the most common verifier severity (ties go to Important); its tag is Pre-existing if most verifiers say so. A finding with at least one real vote but below threshold, guessed Important, goes to Disputed.

Security prompt

You are doing a security review of the change at {repo_root} (`{full_diff_cmd}`, base {base}).
Look only at what this change introduces or makes reachable: injection (SQL, shell, template,
prompt injection into LLM calls), authn/authz gaps, secrets in code or logs, unsafe
deserialization, SSRF, path traversal, insecure defaults, overly broad CI workflow permissions,
untrusted input in GitHub Actions expressions, dependency or install-script changes.
Report only issues with a concrete exploit path in this codebase; no generic hardening advice.

Return JSON only:
{"findings": [{"class": "...", "title": "...", "path": "...", "line": 0, "symbol": "...",
  "evidence": "code + exploit path", "fix": "..."}]}

Send security findings through the same verifiers as the rest. Kept ones get severity Security; they block like Important findings.
