What it does

Review PR is an agent skill from mikeyobrien/ralph-orchestrator. Use when asked to review a PR, run a code review loop, or invoke the ralph reviewer against a pull request number or GitHub URL

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Pull requests and Code review. It works with GitHub. The repository describes itself as: An improved implementation of the Ralph Wiggum technique for autonomous AI agent orchestration. The licence is MIT.

When your agent uses it

  • Asked to review a PR
  • Run a code review loop
  • Invoke the ralph reviewer against a pull request number

Example prompts

  • “/review-pr”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Parse the PR argument
  2. Run the reviewer loop
  3. Display the report
  4. Verify cleanup

What it can do on your machine

Read from SKILL.md and the folder at commit edc2b32. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Review PR loads about 589 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 277 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~589

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Review PR

Run the ralph.reviewer.yml orchestration loop against a pull request. The loop checks out the PR in an isolated worktree, runs tests, reviews the diff, and produces a structured report.

Usage

/review-pr <PR number or URL>

Accepts: 207, #207, or https://github.com/.../pull/207

Execution

1. Parse the PR argument

Extract the PR number from the argument. Strip # prefix or extract from URL path.

2. Run the reviewer loop
bash
ralph run -H ralph.reviewer.yml -p "Review PR #<N>"

Bash tool settings:

  • timeout: 600000 (10 minutes)
  • run_in_background: true

Use TaskOutput with block: true to wait for completion.

3. Display the report

Read and print .ralph/REVIEW-REPORT.md to the conversation.

If the report file doesn't exist (loop failed before the synthesizer hat), check for and display whatever intermediate files exist:

  1. .ralph/review-scope.md — what was scoped
  2. .ralph/review-verification.md — test results
  3. .ralph/review-findings.md — review findings
4. Verify cleanup

Check that the review worktree was removed:

bash
ls -d .worktrees/review-<N> 2>/dev/null
  • If gone: cleanup succeeded, no action needed.
  • If still present: warn the user but do NOT force-remove. Say what's there and let them decide.

Also note the presence of intermediate files (.ralph/review-scope.md, etc.) — they're useful for debugging but the user may want to clean them up later.

Error Handling

SituationAction
Ralph exits non-zeroDisplay error output. Suggest re-running with RALPH_DIAGNOSTICS=1
Report file missingDisplay intermediate files that do exist (scope, verification, findings)
PR argument missingAsk the user for the PR number
PR argument unparseableAsk the user to provide a bare number, #N, or full GitHub URL

What This Skill Does NOT Do

  • Does NOT validate the PR exists (the scoper hat handles that)
  • Does NOT modify any source code (read-only review)
  • Does NOT post comments to GitHub
  • Does NOT own worktree cleanup (verifies only)
  • Does NOT enable diagnostics by default
