code-review SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

code-review from dzhng/duet-agent is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add dzhng/duet-agent/code-review@git:20261021.e955131

Pins git:20261021.e955131 in mdr.lock. Pin the fingerprint instead.

Review changed code for naming, stale references, unnecessary complexity, and comment quality. Use after completing implementation work, before committing, or when the user asks to review or audit code.

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

# Code Review

Review the diff or specified files against these principles.

## 1. Names must reflect current reality

- Variable and function names should describe what they ARE, not what they used to be.
- If the underlying mechanism changed (e.g. FUSE → NFS), all related names must update.
- Ask: would a new reader be confused by this name?

## 2. No stale references

- After refactoring, grep for references to the old approach — dead detection logic, abandoned feature flags, comments mentioning removed code.
- If something was tried and reverted, remove ALL traces. The codebase should look like the current approach was always the plan.

## 3. Simplify detection and guard logic

- A gate like "can this feature run" should check the ONE thing that actually matters.
- Don't chain fallback detections (binary exists OR source exists OR toolchain exists) when one check covers it.

## 4. Comments document WHY, not WHAT HAPPENED

- **Keep:** non-obvious technical discoveries, platform quirks, "if you remove this, X breaks because Y."
  - Good: `// com.apple.provenance causes SIGKILL when spawned as child process`
  - Good: `// umount while server is alive panics the macOS NFS client`

How to install

The exact contents, by fingerprint
mdr add dzhng/duet-agent/code-review@sha256:5b7c5de0b735d878

The line at the top of this page pins the label git:20261021.e955131, 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.
