Agent Creator

Generate specialized agents for autonomous task handling in Claude Code.

When to Use

• Creating task-specific agents (code review, testing, research)
• Building autonomous workflows
• Specialized analysis agents
• Multi-step task automation
• Agent-driven development patterns

Agent System Overview

Agents are specialized Claude instances with:

• Focused purpose: Specific task or domain
• Autonomy: Can make decisions and use tools
• Context: Loaded with relevant skills and knowledge
• Model selection: Choose appropriate model (haiku, sonnet, opus)

Core Workflow

1. Gather Requirements

Ask the user:

• Purpose: What specific task does this agent handle?
• Model: Which model? (haiku=fast/cheap, sonnet=balanced, opus=complex)
• Skills: Which skills should the agent have access to?
• Tools: Which tools can the agent use?
• Constraints: Any limitations or guardrails?
• Location: Project-local or global?

2. Generate Agent Definition

Location:

• Global: ~/.claude/skills/super-claude/plugins/[plugin]/agents/agent-name.md
• Project: /path/to/project/.claude/agents/agent-name.md

Format:

---
name: agent-name
model: sonnet|haiku|opus
description: Clear description of agent's purpose

5. Tool Access: Only tools needed for the task

Anti-Patterns

• ❌ Multi-purpose agents (do one thing well)
• ❌ Vague purpose or workflow
• ❌ No quality standards
• ❌ Wrong model choice (opus for simple tasks)
• ❌ Too many tool permissions

Troubleshooting

Agent Not Performing Well

Solution:

• Check model selection (may need upgrade/downgrade)
• Refine operational principles
• Add more specific skills
• Clarify success criteria

Agent Taking Too Long

Solution:

• Use faster model (sonnet → haiku)
• Narrow scope
• Add time constraints
• Break into smaller agents
