description	Prepare and perform deterministic all-rubric code reviews for working-tree changes, branch/range diffs, GitHub pull requests, or complete repositories. Use when the user asks for a code review.

Review Skill

Requirements: python3 and git; GitHub PR reviews additionally require an authenticated gh CLI.

Resolve all relative paths below against this skill directory.

Scope selection

If the user did not specify what to review, ask a short clarification. Preserve these choices:

• Working tree: staged, unstaged, and untracked local changes.
• Branch/range: current branch versus a base ref, an explicit base..head or base...head range, or a revision expression such as abc123^!.
• GitHub pull request: PR number, URL, or other ref accepted by gh pr view / gh pr diff.
• Repository: complete tracked + untracked repository snapshot, excluding .gitignored files.

Do not ask the user to select rubrics. This skill always reviews with all rubrics in rubrics/.

Prerequisites

For reviewing Github PRs requires the gh binary, and optionally authentication if reading non-public repositories.

Prepare the review packet

Run scripts/prepare_review.py using its absolute path while your shell is in the target repository, or pass --cwd for the target repository. The script finds the git repository root, gathers deterministic input, loads all rubrics, writes a Markdown packet, and prints the packet path plus the intended review-report path.

Examples, where <skill-dir> is this skill directory:

# Uncommitted changes, including staged, unstaged, and untracked files
python3 <skill-dir>/scripts/prepare_review.py --scope working-tree

# Current branch versus main, using merge-base diff semantics
python3 <skill-dir>/scripts/prepare_review.py --scope branch --base main

# Current branch versus another base ref
python3 <skill-dir>/scripts/prepare_review.py --scope branch --base release/v1

# Explicit range expressions
python3 <skill-dir>/scripts/prepare_review.py --scope branch --range 'main...feature-branch'
python3 <skill-dir>/scripts/prepare_review.py --scope branch --range 'v1.2.0..main'
python3 <skill-dir>/scripts/prepare_review.py --scope branch --range 'abc123^!'

# GitHub PR; requires gh to be installed and authenticated
python3 <skill-dir>/scripts/prepare_review.py --scope pull-request --pr 123
python3 <skill-dir>/scripts/prepare_review.py --scope pull-request --pr 'https://github.com/org/repo/pull/123'

# Complete codebase review
python3 <skill-dir>/scripts/prepare_review.py --scope repository

# Override output locations
python3 <skill-dir>/scripts/prepare_review.py --scope working-tree \
  --packet-path .agent/review-packets/my-packet.md \
  --review-output .agent/reviews/my-review.md

Useful options:

• --cwd PATH: directory inside the target git repository.
• --packet-path PATH: where to write the packet Markdown.
• --review-output PATH: path the packet instructs you to use for the final review report.
• --max-lines N and --max-bytes N: packet input truncation limits.
• --json: print a machine-readable summary.

Perform the review

After preparing the packet:

1. Read the printed packet path.
2. Follow the packet instructions exactly.
3. Write the final review report to the packet's Review report target path. If your harness cannot write files, provide the review inline and say that file output was unavailable.
4. Respond to the user with a brief summary and the report path.

If the packet contains a truncation notice with a full-input path, read that full-input file before finalizing whenever your harness can read local files. If you cannot inspect it, state that limitation in the review.

Review expectations:

• Use all bundled rubrics.
• Prioritize concrete, actionable defects over style-only nits.
• Cite evidence from the packet: file names, functions, diff hunks, PR context, or commit log.
• Do not invent findings. If no material issue exists for a rubric, do not force one.
• Include test-quality observations when tests are missing, weak, or mismatched to risk.

Optional browser presentation

Do this if a browser and GUI is on the PATH. After writing the Markdown review report, run:

python3 <skill-dir>/scripts/present_review.py <review-report.md>

This writes a sibling .html file with a small dependency-free renderer and attempts to open it in the default browser when a GUI is available.

Options:

python3 <skill-dir>/scripts/present_review.py <review-report.md> --no-open
python3 <skill-dir>/scripts/present_review.py <review-report.md> --html-path /tmp/review.html

If no GUI or browser is available, continue normally and tell the user where the Markdown and HTML files are.
