review-pr

A command that reviews a specific GitHub pull request using several specialized code reviewers. A pull request is a proposed set of changes awaiting review before it is merged.

In plain words
What is it for?
Use it with a pull-request number to inspect changed files, collect the branch and commit information, run the review agents, and prepare findings with the context needed for inline GitHub comments.
Why use it?
It gathers the pull request’s details and diff, then checks the changes for security, coding patterns, quality, and project standards in one workflow.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,912 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

review-pr scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Review Pull Request

Review code changes in a specific pull request using a comprehensive multi-agent code review process with specialized reviewers for security, patterns, quality, and standards.

Usage

/review-pr <PR_NUMBER>

Examples:

  • /review-pr 123 - Review pull request #123
  • /review-pr 45 - Review pull request #45

Instructions

You are coordinating a comprehensive code review for pull request #$ARGUMENTS.

Step 1: Gather PR Information

First, collect information about the pull request:

  1. Get PR details, changed files, and the HEAD commit SHA:

    gh pr view $ARGUMENTS --json number,title,body,baseRefName,headRefName,headRefOid,url,files
    gh pr diff $ARGUMENTS
    
  2. Extract key information:

    • List of changed files
    • PR URL for linking in review comments
    • HEAD commit SHA (headRefOid) - required for posting inline comments
  3. IMPORTANT: Save the diff output - you will need it to:

    • Include relevant diff context snippets in each finding
    • Determine the exact diff line numbers for inline comments (line numbers as they appear in the diff, not file line numbers)
    • Determine the side (RIGHT for additions +, LEFT for deletions -)
  4. Create the .codereviews/ directory if it doesn't exist.

Step 2: Launch Parallel Code Reviews

Launch FOUR sub-agents in parallel using the Task tool. Each agent MUST receive:

  • The PR number: $ARGUMENTS
  • The list of changed files (so they stay scoped to PR files only)
  • The PR URL for generating clickable links

CRITICAL: You MUST launch all four agents in a SINGLE message with FOUR parallel Task tool calls:

  1. security-compliance-reviewer (subagent_type: security-compliance-reviewer)
    • Prompt: "Review PR #$ARGUMENTS for security compliance. Files changed: [list files]. PR URL: [url]. Focus on authentication, secrets, token handling, logging security, and input validation. Output your review in the structured markdown format."

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

review-pr is a command published in the GitHub repository microsoft/Agent365-Samples (106 stars, last pushed 29d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,912 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
