Codex Plan Workflow Skills

Three Codex skills that enforce a plan-first workflow via explicit delegation.

• cc-plan: produce a concrete implementation plan
• cc-explore: collect evidence to support the plan
• cc-task: implement an approved plan

Workflow

Use the skills in this order:

1. $cc-plan
2. If evidence is missing, $cc-explore
3. $cc-task

Install

Codex supports repo-scoped and user-scoped skills. Choose one of the official options below.

Option A: Repo-scoped (recommended)

Copy the three skill folders from this repo (skills/cc-plan, skills/cc-explore, skills/cc-task) into your target repository’s .codex/skills/ directory:

.codex/skills/
  cc-plan/
  cc-explore/
  cc-task/

This makes the skills available to anyone who checks out the repo. Restart Codex to pick up new skills.

Option B: User-scoped

Copy the three skill folders from this repo (skills/cc-plan, skills/cc-explore, skills/cc-task) into your user skills directory:

~/.codex/skills/
  cc-plan/
  cc-explore/
  cc-task/

This makes the skills available across all repositories for your user. Restart Codex to pick up new skills.

Option C: Skill installer

Codex includes a built-in $skill-installer for installing curated skills (for example, $skill-installer linear). You can also prompt it to download skills from other repositories. If you use the installer, follow its prompts and then restart Codex after installation.

Notes

• Source prompts are stored under each skill's references/ directory (sourced from Piebald-AI/claude-code-system-prompts).
• Keep SKILL.md concise; put long prompt text or references into references/.
