Spawning Plan

Design the optimal agent team for the task. Performant, precise, minimal. Docs: https://code.claude.com/docs/en/agent-teams.md

Task: $ARGUMENTS

Step 1: Context Gathering (Silent — no user interaction)

A) Read environment:

CLAUDE.md — workflow rules, conventions, constraints
Project manifests — package.json, pyproject.toml, Cargo.toml, go.mod, etc.
Directory structure — src/, app/, packages/, test dirs, monorepo indicators

B) Inventory existing agents:

Scan ~/.claude/agents/*.md — reuse matching agents instead of creating duplicates

C) Analyze task complexity:

Work type: research, implementation, review, debugging, refactoring
Scope: single-layer vs cross-layer
Parallelism: can work split into independent streams?
Complexity → team size: simple (2 agents), medium (3-4), complex cross-cutting (5-6, max 8)

Step 2: Ask Team Questions (AskUserQuestion Tool)

Ask 3-5 questions based on Step 1 findings. Not all apply every time — pick what matters.

Team Composition — "For this [work type] on [stack], I'm thinking [N] agents: [role list]. What would you change?" Options: Perfect / Add role / Remove role / Different approach
Coordination — "How should agents work together?" Options: Independent (no messaging) / Team (peer messaging) / Hub-spoke (lead coordinates)
Dependencies — "Work order?" Options: All parallel / Sequential (A→B→C) / Mixed
Models — "Model allocation: opus (research), sonnet (implementation), haiku (scanning). Adjust?" Options: As suggested / All opus / All sonnet / Custom
Agent Reuse (only if matching agents found in Step 1B) — "Found existing [agent-name] that handles [capability]. Reuse it?" Options: Reuse / Create fresh / Both

Step 3: Output & Approval

Present clean TEAM PLAN:

## TEAM PLAN

Task: [description]
Pattern: [independent | team | hub-spoke]
Work Order: [parallel | sequential | mixed]
Agents: [count]

### Teammates

- Teammate 1: [Name] ([Role])
  Description: [1-2 line expertise and specialization]
  Model: [opus|sonnet|haiku]
  Type: [general-purpose | feature-dev:code-X | reuse ~/.claude/agents/X.md]
  Responsible for: [specific deliverable]
  Depends on: [— | Teammate N]

- Teammate 2: [Name] ([Role])
  Description: [1-2 line expertise and specialization]
  Model: [opus|sonnet|haiku]
  Type: [general-purpose | feature-dev:code-X]
  Responsible for: [specific deliverable]
  Depends on: [— | Teammate N]

- ...

### Research (injected into agent prompts)
- [key finding or best practice 1]
- [key finding or best practice 2]

Final Approval (AskUserQuestion Tool)

"Launch this team?"
- Deploy & Save — spawn agents and save as reusable skill
- Deploy Once — spawn agents, one-time
- Adjust — change something (iterate plan)
- Cancel — abort

Deploy & Save → save team as skill at ~/.claude/skills/<team-name>/SKILL.md for future use via /<team-name> [task]. Saved skill skips planning, bakes in agent definitions, uses $ARGUMENTS for task input.

Adjust → ask what to change → regenerate plan → ask again. Loop until approved.

Deploy Once → spawn immediately, no save.

Cancel → stop.

Spawning Execution

Based on chosen pattern:

Independent: parallel Task tool calls, one per agent
Team: TeamCreate → TaskCreate per agent → Task tool with team_name → TaskUpdate for dependencies
Hub-spoke: TeamCreate with lead agent (opus) that delegates via SendMessage
