Tools

Reviews pull requests with several parallel subagents, scores each finding by confidence to filter out false positives, and can post the results as PR comments. Official Anthropic plugin; requires a logged-in GitHub CLI.

GitHub's official CLI: manage pull requests, issues, releases and Actions workflows from the terminal. Most commands support --json output that agents can parse, and an official agent skill is available. Run gh auth login first.

GitHub's official MCP server: lets agents read and write repositories and code, manage issues and pull requests, and check Actions workflows and code-scanning alerts. Use the hosted remote server or run it locally in Docker; needs a personal access token or OAuth.

Connects GitHub's official remote MCP server to manage issues and PRs, review code, search repos and call the GitHub API from Claude Code. Requires GITHUB_PERSONAL_ACCESS_TOKEN.

Creates or updates a pull request description that explains why the change exists in one sentence, flags up to three things to note, and outlines the implementation with diff-style file, component and call trees. Uses the GitHub CLI; runs only when invoked by name.

Draws a code change or part of a codebase as an animated architecture or data-flow diagram. The agent writes a JSON graph, validates and renders it to SVG with the PR Lens CLI, then pushes it to a prlens.dev canvas or attaches it to a GitHub, GitLab or Bitbucket pull request.

Manages stacked branches and dependent pull requests with the gh stack GitHub CLI extension: splits work into layered branches with one PR each, then handles push, submit, sync, rebase and merge, using flags that keep commands non-interactive for agents. Official GitHub skill.

Greptile's official AI code review plugin: view and address review comments on GitHub or GitLab PRs, review the current branch before opening a PR, and search your team's knowledge base and coding standards. Needs a Greptile account (OAuth, free tier available) and Node locally.
