What problem does it solve? Reviewers, team leads, and PIs returning to a project after time away need a fast, high-level picture of what changed without reading every commit. This Skill generates an executive summary of repository activity over a chosen time window, including commit themes, churn metrics, and human signoff attestation coverage. ## Core Features & Use Cases - Preset Time Windows: Summarize activity over 1 day, 1 week (default), 2 weeks, or 1 month using validated duration grammar mapped to git --since arguments. - Executive Report: Aggregates feature commit counts, active authors, unique files touched, and cumulative insertions/deletions, grouped into feature themes. - Attestation Audit: Parses Signoff-Reviewed-Commit-SHA and Signoff-Status trailers to classify commits as verified, downgraded, or unsigned. - Interactive Drill-Down: Navigate commit lists, changed files, or delegate to the explain-diff skill for hunk-level walkthroughs. - Use Case: A PI returning from a two-week conference runs /catchmeup 2w origin/main to see what the team shipped and which commits lack human signoff. ## Quick Start Ask the agent to run /catchmeup with a duration like 1w and a target ref such as origin/main to get an executive summary of recent repository activity.
