name: catchup description: This skill should be used when the user asks to "catch me up", "what's on this branch", "summarize this branch", "what changed since main", or wants a structured summary of commits, changed files, and current state of the working branch compared to main/master.

Catchup: Branch Summary

Quickly understand what has changed in the current working branch compared to main/master.

Behavior

1. Detect base branch (main or master)
2. Detect platform (check for .gitlab-ci.yml → glab, otherwise → gh)
3. Get commit log since divergence from base branch
4. Get all changed files with git diff <base>...HEAD --stat
5. Read changed files for context

Output Format

Commit Summary

• List commits with their semver prefixes and short descriptions

Changes by Area

Group changed files into categories:

• Migrations: new/modified database migrations
• Config: settings files, CI config, dependency changes
• Source: application code changes
• Tests: new/modified tests

Key Changes

• Highlight breaking changes or API modifications
• Note new dependencies added (check pyproject.toml, package.json, Cargo.toml diffs)
• Flag any renamed/moved files

PR/MR Context

• If on a branch with an open PR/MR, show its title and status
• Use gh pr view or glab mr view depending on detected platform

Current State

• Any uncommitted changes
• Potential issues or blockers
