checkpoint

Quick Review

Excellent skill with clear, actionable instructions for creating safe git checkpoints. The description accurately reflects capabilities, and the step-by-step workflow provides comprehensive task knowledge including preflight checks, safety guardrails, selective staging, structured commit messages, and postflight verification. Structure is logical and easy to follow. Novelty is moderate-to-good: while git operations are standard, the safety-first approach with domain-specific exclusions (competition data, secrets, artifacts) and structured commit message generation with agent ID parsing adds meaningful value and reduces risk that a basic CLI agent might miss.
