What problem does it solve? Tracking changes across multiple repositories and branches is tedious and error-prone, especially when the same project exists in both primary and submodule locations. This Skill automates the collection of branch inventories, commit logs, contributor activity, and cross-repo sync status into a single structured audit report. ## Core Features & Use Cases - Multi-repo branch inventory: Collects branch lists, commit counts, and last-activity dates from four repo locations (primary and submodule copies of backend and frontend). - Categorized change summary: Groups commits into categories like infrastructure, models and migrations, API, seed data, frontend features, bug fixes, and security. - Cross-repo sync check: Compares HEAD commits between primary and infra copies to detect drift. - Use Case: Before a release, ask for a changelog audit since the last release date to get an executive summary, contributor breakdown, stale branch recommendations, and unmerged work flagged in Docs/CHANGELOG-AUDIT.md. ## Quick Start Run a changelog audit across all repos since 2024-01-01 and write the report to Docs/CHANGELOG-AUDIT.md.
