Prompt

I am creating a standard utility agent for documentation refactoring in `.claude/agents/doc-helper.md`. If I do not specify a specialized high-complexity or high-volume model, which default model identifier should be set in the YAML frontmatter?

What was checked, without and with the skill

Manage Agents

Create and manage specialized Claude Code subagents with custom capabilities, tool access, and expertise domains.

Use this skill when you need to:

Create new subagents for specialized tasks
Modify existing agent configurations
Set up domain experts (Python, Neo4j, Testing, etc.)
Configure tool access and MCP server permissions
Understand agent structure and best practices

Quick Start

To create a new agent:

Understand the Need: What specialized capability or domain expertise is needed?
Choose Location: Project-level (.claude/agents/) or user-level (~/.claude/agents/)
Define Configuration: Name, description, model, tools, and permissions
Write System Prompt: Clear instructions for the agent's specialized role
Test & Validate: Invoke with @agent-name and verify behavior

Core Sections

Instructions
- Step 1: Analyze Requirements - Determine expertise domain, tool needs, and location
- Step 2: Create Agent File - Choose project vs user location
- Step 3: Write Agent Configuration - YAML frontmatter template
- Step 4: Configure Tool Access - Explicit tools, all tools, or no tools
- Step 5: Configure MCP Access - Specific servers, all servers, or all resources
- Step 6: Select Model - Sonnet, Opus, or Haiku based on complexity
- Step 7: Write System Prompt - Clear, actionable, quality-focused instructions
- Step 8: Test the Agent - Verify behavior and tool access
- Step 9: Document Integration - Update dispatch.md and CLAUDE.md
Common Patterns
- Pattern 1: Domain Expert - Read-only analysis and recommendations
- Pattern 2: Code Generator - Write access with quality gates
- Pattern 3: Orchestrator - Planning agent that delegates
