Questions
What are planning skills?
Skills for specs, architecture, and brainstorming before you build. Each one is a folder with a SKILL.md file that Codex reads when a task matches.
How do I install a planning skill?
Copy the skill folder into .agents/skills/ and start a new Codex session. Each skill page shows the exact command.
Can I trust these skills?
We run a basic automated check for risky patterns. It is not a full audit. Read a skill before you install it.
