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

Inputs
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|

--apply |
switch | No | False | Unsafe: Attempt to fast-forward/merge |
Outputs
- Console Report: Matrix of repo status.
- Markdown Report:
REPO_SYNC_REPORT.md.
Preconditions
- All targets must be valid git repositories.
