What problem does it solve?
Propagate wheelhouse template changes and registry-pin chains across all fleet repositories. This skill packages the canonical fleet-repo list, the FLEET_SYNC=1 sentinel pattern, the worktree-per-repo loop, push-direct plus PR-fallback, and worktree-cleanup that survives mid-loop crashes. It is used when a wheelhouse template SHA needs to land in every fleet repo or when a registry pin chain must propagate, or when batching multiple SHAs into a single cascade wave.
Core Features & Use Cases
- Cascade template and registry-pin changes across the fleet set with deterministic, auditable execution.
- Two operational modes: template cascade (propagates wheelhouse/template SHA to all fleet repos) and registry-pin cascade (propagates registry pins through the fleet and registry).
- Safe, idempotent handling with per-repo worktrees, direct-push or PR fallback, and post-cascade lockfile reconciliation.
Quick Start
Run the canonical cascade with node .claude/skills/fleet/cascading-fleet/lib/cascade-template.mts <template-sha> to propagate the change to all fleet repos.
