/add-sub-agent

Use the sub-agent-writer agent to create a new agent.

Context Detection:

1. If marketplace.json exists at project root → List plugins to choose from
2. If .claude-plugin/plugin.json exists in current directory → Use current plugin's agents/ directory
3. Otherwise → Use .claude/agents/ (standalone project)

The sub-agent-writer will:

• Detect context automatically using the rules above
• Gather agent requirements and specifications
• Create properly formatted agent markdown file in the appropriate directory
• Follow sub-agent-design skill patterns for autonomous delegation
