About

Lint On Save is a codex hook that automates events in your Codex workflow — from notifications to linting and git guardrails. Hooks install with the --hook flag and run without manual invocation.

Source package path: am-will/codex-skills/hooks/aitmpl-codex/development-tools/lint-on-save on GitHub (am-will/codex-skills).

Key features

  • Automates Codex lifecycle events after install
  • Runs in the background — no prompt needed once configured
  • Install with the --hook flag via npx
  • Fits coding automation and guardrail workflows
