Guide the user to create an .agent.md.
Extract from Conversation
First, review the conversation history. If the user has been using the agent in a specialized way (e.g., restricting tools, following a specific persona, focusing on certain file types), generalize that into a custom agent. Extract:
- The specialized role or persona being assumed
- Tool preferences (which to use, which to avoid)
- The domain or job scope
Clarify if Needed
If no clear specialization emerges from the conversation, clarify:
- What job should this agent do?
- When should it be picked over the default agent?
- Which tools should it use (or avoid)?
Iterate
- Draft the agent file and save it.
- Identify the most ambiguous or weak parts and ask about those.
- Once finalized, summarize what the agent does, suggest example prompts to try it, and propose related customizations to create next.
Remember to follow the agent-customization guidelines to create highly effective agents.

Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
Replace with description of the skill and when Claude should use it.
Use when creating new skills, editing existing skills, or verifying skills work before deployment
This skill should be used when the user wants to "create a skill", "add a skill to plugin", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices for Claude Code plugins.
Use when executing implementation plans with independent tasks in the current session
How to use it
Take microsoft/create-agent from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
