Spawn Team Skill (Proxy Pattern)

Creates an agent team where the team lead fetches agent configurations from MCP and injects them into teammate prompts. This is required because team agents run in separate tmux sessions and cannot access MCP tools directly.

When to Use

• User requests parallel work across multiple files
• Tasks can be broken into independent units
• Multiple agents needed for efficiency

Proxy Pattern Explained

Problem: Team agents spawned via Task tool with team_name run in separate Claude Code processes. They do NOT inherit MCP server connections and cannot call mcp__agenthub_http__call_agent.

Solution: The team lead (which HAS MCP access) fetches each agent's config BEFORE spawning, then injects the system_prompt into the teammate's prompt.

Workflow Steps

1. Analyze

• Read all relevant files
• Break request into independent tasks

2. Create Team & Tasks

TeamCreate(team_name="descriptive-name", description="purpose")
TaskCreate(subject="Task description", description="Details", activeForm="Doing X")

3. Fetch Agent Configs (Proxy Pattern)

For each unique agent type needed, the team lead calls:

mcp__agenthub_http__call_agent with name_agent="{agent-type}"

Extract response.agent.system_prompt — this is the agent's operating manual. Cache results: if multiple agents share the same type, fetch only once.

4. Spawn Teammates (Parallel)

Choose the right agent type per task. Inject the fetched system_prompt into each prompt.

Teammate prompt template:

You are a {agent_type} teammate on team "{team_name}". Your name is "{teammate_name}".

YOUR AGENT CONFIGURATION (loaded from MCP server by team lead):
{system_prompt from call_agent response}

YOUR TASK (Task #{task_number}):
{task_description}

WORKFLOW:
1. Read the target file(s) to confirm current state
2. Make the required changes following the agent configuration above
3. Verify your changes by reading the file again
4. Use AskUserQuestion to ask the user to confirm your work
5. After user confirmation, mark Task #{task_number} as completed via TaskUpdate
6. Send a message to the team lead reporting completion

IMPORTANT: Do NOT skip step 4 (user confirmation) — it is mandatory.

5. Monitor

• Wait for teammate messages
• Verify results by reading files

6. Clean Up

SendMessage(type="shutdown_request", recipient="teammate-name")
TeamDelete()

Key Rules

• Team lead MUST fetch agent config via call_agent BEFORE spawning each teammate
• The fetched system_prompt MUST be injected into the teammate's Task prompt
• Each teammate MUST ask user confirmation before reporting done
• Spawn teammates in parallel when tasks are independent
• Team lead verifies results before shutting down
• The subagent_type in Task tool should match the agent type used in call_agent
