Codex Plugins

Public Codex plugin marketplace for small workflow skills.

It currently packages one plugin, codex-plugins, with these skills:

• $ultrareview-plan: review and refine an existing implementation plan with focused subagents.
• $ultradev: staged implementation through serial worker agents, followed by verification.
• $ultrareview: parallel multi-lane review of a focus area or current changes.
• $ultraadversarialreview: Claude-backed adversarial review with local validation and reprioritization of candidate findings.
• $ultrasimplify: behavior-preserving simplification through parallel cleanup review agents, approved fixes, and verification.

These skills are experimental and intended for local Codex use.

Layout

• .agents/plugins/marketplace.json: marketplace manifest for Codex.
• plugins/codex-plugins/.codex-plugin/plugin.json: plugin manifest.
• plugins/codex-plugins/skills/: packaged Codex skills.
