SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Reviewing pull requests in the Microsoft MCP repository requires checking many repository-specific concerns such as security boundaries, AOT compatibility, Azure SDK usage, tool contract compatibility, and test evidence, which is easy to miss in manual reviews.

Core Features & Use Cases

  • Multi-lens review: Applies eight fixed lenses covering security, C# correctness and AOT, Azure service integration, architecture, testing, tool contracts, documentation, and product intent, plus dynamic lenses triggered by changed files.
  • Finding triage: Verifies, deduplicates, and severity-ranks candidate findings so only high-confidence, actionable comments survive.
  • Structured output: Produces line-anchored draft comments in interactive sessions or comment-only reviews in GitHub Copilot Code Review.
  • Use Case: Given a pull request number or diff, the Skill gathers PR context, reads repository guidance like AGENTS.md, builds a change map, and returns a concise set of inline review comments.

Quick Start

Review pull request 123 in this repository and return draft inline comments for any blocking or warning findings.

FAQPage Schema
How do I review a pull request with this Skill?▼

Provide a pull request number, URL, branch, or diff. The Skill gathers PR context, reads repository guidance files, builds a change map, applies review lenses, and returns triaged inline comments.

What does the MCP code review check for?▼

It checks security issues, C# correctness and AOT compatibility, Azure SDK usage, architecture and statelessness, test coverage, tool contract compatibility, documentation accuracy, and alignment with the linked issue.

Can this Skill approve or modify a pull request?▼

No. It works read-only and never approves, requests changes, resolves threads, or modifies code. In interactive sessions it returns draft comments for human approval before posting.

How are review findings filtered and prioritized?▼

Candidate findings are verified against the diff and surrounding code, deduplicated, and assigned blocking, warning, or nit severity. Only high-confidence findings worth a maintainer's time survive triage.

Does it work with GitHub Copilot Code Review?▼

Yes. In GitHub Copilot Code Review it posts qualified inline comments directly as a comment-only review. In interactive IDE and CLI sessions it returns drafts for user approval first.
