name: github description: Inspects GitHub pull requests, diffs, files, and reviews via github_* tools. Use for PR details, file lists, comments, reviews, and reading repo file content at a ref.

GitHub

Purpose

Operate on GitHub pull requests and repository files: fetch PR metadata, list changed files, read diffs, post comments or reviews, and load file content at a path/ref.

When to Use

• Inspect a PR by URL or owner/repo/number.
• List PR files or diff before reviewing.
• Submit a review (APPROVE, REQUEST_CHANGES, COMMENT) or inline comment.
• Read a file from a repository at a branch or SHA.

When NOT to Use

• Opening or merging PRs in this skills repo → publish-skill / user git workflow unless github_* create tools exist and are requested.
• CI babysitting → babysit (Cursor skill) when available.
• Non-GitHub VCS.

Expected Outcome

• PR state, title, body, and file list from tool responses.
• Reviews/comments only after reading the PR/diff when the user asked for a review.
• File content matches github_get_file_content at the requested ref.

Inputs to Gather

• PR URL or owner, repo, pull_number.
• Review body and event when submitting a review.
• File path and ref for content reads.

Workflow

1. Get PR: github_get_pull_request (URL or coordinates).
2. Files/diff: github_list_pull_request_files, github_get_pull_request_diff as needed.
3. Review/comment: github_create_review or github_create_pull_request_comment after analysis.
4. File read: github_get_file_content with path and ref.
5. Summarize findings with links/SHAs from responses.

Domain rules

1. URL or owner/repo/number—use what the user provided.
2. Get PR before reviewing—read files/diff first for substantive reviews.
3. Review events: APPROVE, REQUEST_CHANGES, COMMENT per user intent.
4. File content via dedicated tool, not guessed from diff alone.

Main tools

• github_get_pull_request, github_list_pull_request_files, github_get_pull_request_diff
• github_create_pull_request_comment, github_create_review
• github_get_file_content

Examples

PR details from URL: github_get_pull_request with url; return title, state, author.

LGTM comment: github_create_pull_request_comment or review with COMMENT event and user text.

Review / Decision / Execution Criteria

• Reviews must reflect evidence from diff/files.
• Do not approve without user-aligned criteria.

Output Format

1. PR identifier and actions.
2. Summary of changes or review text posted.
3. Errors.
4. Follow-up checks if requested.

Quality Bar

• Specific line/file references when commenting.
• No invented CI status.

Safety and Boundaries

• No tokens in output.
• Confirm before REQUEST_CHANGES on behalf of the user when policy is unclear.

Escalation / Dispatch Rules

• Local git operations without API → shell/git with user approval, not fabricated API results.
