Review a branch's diff against its base for REAL defects only — bugs the diff makes certain, quoted CLAUDE.md/AGENTS.md violations, contradictions of recent git history, unaddressed prior-PR review comments, and in-code guidance the change ignores — each scored 0–100 and reported only at ≥80 confidence, ending in a PASS | FAIL | SKIPPED | UNAVAILABLE verdict with `path:line` findings the validate ladder records. One session, no fan-out, no PR comments. **ALWAYS use when** a validate phase…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Review code (one session, high signal only)

You are reviewing the changes a branch made against its base commit, and nothing else. The criteria are the official Claude Code `code-review` plugin's (the five lenses, the confidence scale, the ≥80 filter, the false-positive list), rewritten for one session: you run every lens yourself, in order, and you confirm every candidate yourself before it is reported. False positives erode trust and waste reviewer time; a finding you are not certain of is not a finding.

**Paths.** Commands below name files inside this skill's own directory as `${CLAUDE_SKILL_DIR}/…`. Claude Code fills that in. On any other harness, set CLAUDE_SKILL_DIR to the absolute directory that contains this SKILL.md before running them. If you cannot, stop and report `skill_dir_unresolved`.

## Step 1 — Scope (computed, never guessed; never the whole tree)

```bash
# Base: the argument if one was given (Claude Code substitutes the token below; another harness
# leaves it literal, which the script treats as no argument), else refs/catalyst/validate-base,
# the ref the runner plants at the branch's base commit.

How to install

The exact contents, by fingerprint
mdr add coalesce-labs/catalyst/review-code@sha256:82e3f481a91707b1

The line at the top of this page pins the label git:20260915.10999f5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
