# Agent Creator Skill ## Purpose This skill acts as an expert agent architect, generating complete, ready-to-use Claude Code sub-agent configuration files from user descriptions. It gathers requirements through structured questions, fetches current documentation, and produces well-structured agent definitions. ## Workflow ### Step 1: Gather Requirements Before creating any agent, use `AskUserQuestion` to collect essential information: ``` Question 1: "What is the primary purpose or goal of this agent?" Header: "Agent Goal" Options: - Code analysis/review - Code generation/writing - Documentation tasks - Testing/debugging - Other (free text) Question 2: "What domain should this agent be an expert in?" Header: "Expertise" Options: - Frontend development - Backend development - DevOps/Infrastructure - Data/Analytics - Other (free text) Question 3: "What tools should this agent have access to?" Header: "Tools" MultiSelect: true Options: - Read, Grep, Glob (code exploration) - Edit, Write (code modification) - Bash (command execution) - WebFetch (documentation/research) ``` ### Step 2: Fetch Documentation Retrieve up-to-date sub-agent documentation: ``` WebFetch: https://code.claude.com/docs/en/sub-agents Prompt: "Extract the sub-agent configuration format, available frontmatter fields, and best practices for creating agents" ``` ### Step 3: Analyze and Design Based on gathered requirements: 1. **Devise a name**: Create a concise, descriptive `kebab-case` name (e.g., `api-tester`, `dependency-manager`) 2. **Select a color**: Choose from: red, blue, green, yellow, purple, orange, pink, cyan 3. **Write delegation description**: Craft an action-oriented description stating *when* to use the agent. Include trigger phrases for when users should invoke it. Example: "Use proactively when user says 'review my code' or 'check for bugs'. Specialist for code quality assessment." 4. **Fetch tools available**: Use WebFetch to get the current list of available tools from Claude Code documentation, as tools may change over time 5. **Determine tools needed**: Based on the agent's purpose and the available tools, select the minimal tool set required for the agent's tasks ### Step 4: Construct the Agent File Generate a complete markdown file following the template in `references/agent-template.md`. ### Step 5: Write the Agent File Save the generated agent to: `~/.claude/agents/<generated-agent-name>.md` Use the Write tool to create the file at the correct location. ## Best Practices - Keep descriptions action-oriented and specific about when the agent should be used - Include "Use proactively when..." in descriptions for automatic delegation - Minimize tool access to only what's necessary for the agent's purpose - Write clear, numbered instructions that guide the agent step-by-step - Include domain-specific best practices relevant to the agent's expertise - Define expected output format clearly ## Additional Resources ### Reference Files - **`references/agent-template.md`** - Complete agent file template with all sections
