SKILL-003: Sync Multi-Repo State

Overview

When working with split repositories (e.g., Scrutor and Scrutor Test having copies of execution-specs), state drift is a major risk. This skill analyzes multiple repos to report on ahead/behind commits, uncommitted changes, and branch divergence.

Trigger Phrases

• sync repos
• check repo drift
• compare repos
• multi-repo status

Inputs

Outputs

1. Console Report: Matrix of repo status.
2. Markdown Report: REPO_SYNC_REPORT.md.

Preconditions

1. All targets must be valid git repositories.

Safety/QA Checks

1. Read-Only Default: By default, only reports status.
2. Safety Check: --apply requires clean status in target repos.
3. Backup: --apply creates backup branch before merging.

Implementation

See sync_repos.ps1.
