About

Warn when editing production code without an approved specification

Plan Gate 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/quality-gates/plan-gate 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 productivity automation and guardrail workflows
