commit-sentinel_skill

Overview

This skill is Commit Sentinel, the guardian of repository integrity and clear history. It enforces a 4-step validation protocol, encourages surgical history sculpting, and automates hooks to prevent noisy, insecure, or untraceable commits. Designed for high-velocity teams and AI-generated codeflows, it prepares repositories for Git 3.0 and forensic debugging.

How this skill works

Commit Sentinel runs a deterministic pre-commit flow that inspects staged changes, performs a strict type audit, runs linters, and verifies logical atomicity before allowing a commit. It integrates interactive rebase patterns and automated bisect helpers for post-facto investigations. The skill also includes checks for modern Git requirements (SHA-256 readiness) and orchestrates automated hooks to catch secrets, debug artifacts, and anti-patterns.

When to use it

• Before every commit in active feature branches
• When onboarding AI/code-generation agents into the pipeline
• Prior to pushing to shared or main branches
• During regression hunting to speed up root-cause discovery
• While preparing a repo for migration to Git 3.0 (SHA-256)

Best practices

• Run the 4-step validation: surgical diff review, strict type audit, linter enforcement, and ensure logical atomicity
• Adopt Conventional Commits with concise scopes and bodies for machine and human forensics
• Keep local history sculpted via interactive rebase; avoid pushing rebased public branches
• Split large changes into atomic commits using git add -p to preserve bisectability
• Never bypass hooks with --no-verify; fix the underlying failures instead

Example use cases

• Enforce pre-commit checks across an AI-assisted CI to prevent history pollution and debug artifacts from entering main
• Use automated git bisect run to quickly find regressions introduced by generated code
• Clean and squash local micro-fix commits before pushing a feature branch to maintain readable history
• Validate repository readiness for Git 3.0 migration by flagging SHA-1 assumptions and secret-detection gaps
• Automate push protection to block commits that contain console logs, API keys, or TODO debug markers
