About

Create comprehensive, phased implementation plans with atomic tasks

Planner is a codex skill — a focused instruction set the agent loads when you need specialized design help. Skills are lighter than full plugins and install with the --skill flag.

Source package path: am-will/codex-skills/skills/planner on GitHub (am-will/codex-skills).

Key features

  • Specialized agent instructions for design tasks
  • Lighter than a full plugin — focused playbook the agent loads on demand
  • Install with the --skill flag via npx
  • Ideal when you want Planner expertise without a full integration

How to install

  1. 01

> Invoke the Planner skill to review this code change
