Resolve configuration precedence and permission mode before changing execution behavior; app features are not automatically CLI commands. 1. Verify the requested behavior and resulting artifacts. Use [agent-project](../agent-project/SKILL.md) for shared instruction and skill discovery, and [agent-mcp](../agent-mcp/SKILL.md) for MCP registration. ## Official Skills - [OpenAI skills catalog](https://github.com/openai/skills) · [OpenAI plugins catalog](https://github.com/openai/plugins): choose a package that matches the task and check already installed native skills first. - [Skills and plugins documentation](https://learn.chatgpt.com/docs/skills-and-plugins): current discovery and customization entrypoint. - For requested installations, follow the [vendor-skill policy](../agent-project/references/vendor-skills.md) and retain the existing pac
