/reconcile — Multi-Session Drift Check

When running multiple Claude Code sessions in parallel (especially with worktrees), files can drift out of sync. This skill scans for inconsistencies and proposes fixes.

Invocation: deliberately model-invocable — the scan is read-only and auto-triggering when drift smells is the point. Anything that changes files is proposed, never applied.

When to Use

• After merging worktree branches back to the default branch
• When something "feels off" after parallel work
• After a crash where multiple sessions were open
• As a periodic sanity check during heavy parallel workflows
