Review a pull request and produce a human-voiced, copy-paste-safe review — first person, evidence first, findings as complete sentences ordered by severity (Blocker / Important / Recommended / Nice-to-have as internal triage, never as labels), each with file:line evidence and a disposition. Use when the user asks to review a PR, "code review", "review this diff", "verify the changes before merge", or asks for a second opinion on someone else's branch. Output is the review in chat — never run…

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

# Reviewing Code

Produce a PR review that reads like a competent engineer wrote it after doing the work. It applies a security lens, a comprehension audit, and structural checks, triages findings by severity internally, and delivers them as first-person prose — evidence first, disposition in every finding, copy-paste-safe for GitHub.

## Read first (always)

List `learnings/` and read every file relevant to the current PR (the touched modules, frameworks, or risk areas). Project-specific review conventions, severity adjustments, banned patterns, or scope rules live there and override the defaults in this SKILL.md. If a learning conflicts with this file, **the learning wins** — mention it to the user.

## Tradeoff — when to apply, when to lighten up

Apply the full discipline (security lens + comprehension audit + checklist + grep) for **production-bound PRs** touching shared services, payments, auth, user data, AI runtime, or anything externally observable.

How to install

The exact contents, by fingerprint
mdr add cristhianzl/claude-skills-czl/reviewing-code@sha256:f8055882257619d2

The line at the top of this page pins the label git:20260924.15ff81b, 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.
