+description: Orchestrate multiple agents for complex tasks
+agent: planner
+subtask: true
+---
+
+# Orchestrate Command
+
+Orchestrate multiple specialized agents for this complex task: $ARGUMENTS
+
+## Your Task
+
+1. **Analyze task complexity** and break into subtasks
+2. **Identify optimal agents** for each subtask
+3. **Create execution plan** with dependencies
+4. **Coordinate execution** - parallel where possible
+5. **Synthesize results** into unified output
+
+## Available Agents
+
+| Agent | Specialty | Use For |
+|-------|-----------|---------|
+| planner | Implementation planning | Complex feature design |
+| architect | System design | Architectural decisions |
+| code-reviewer | Code quality | Review changes |
+| security-reviewer | Security analysis | Vulnerability detection |
+| tdd-guide | Test-driven dev | Feature implementation |
+| build-error-resolver | Build fixes | TypeScript/build errors |
+| e2e-runner | E2E testing | User flow testing |
+| doc-updater | Documentation | Updating docs |
+| refactor-cleaner | Code cleanup | Dead code removal |
+| go-reviewer | Go code | Go-specific review |
+| go-build-resolver | Go builds | Go build errors |
+| database-reviewer | Database | Query optimization |
+
+## Orchestration Patterns
+
+### Sequential Execution
+```
+planner → tdd-guide → code-reviewer → security-reviewer
+```
+Use when: Later tasks depend on earlier results
+
+### Parallel Execution
+```
+┌→ security-reviewer
+planner →├→ code-reviewer
+└→ architect
+```
+Use when: Tasks are independent
+
+### Fan-Out/Fan-In
+```
+         ┌→ agent-1 ─┐
+planner →├→ agent-2 ─┼→ synthesizer
+         └→ agent-3 ─┘
+```
+Use when: Multiple perspectives needed
+
+## Execution Plan Format
+
+### Phase 1: [Name]
+- Agent: [agent-name]
+- Task: [specific task]
+- Depends on: [none or previous phase]
+
+### Phase 2: [Name] (parallel)
+- Agent A: [agent-name]
+  - Task: [specific task]
+- Agent B: [agent-name]
+  - Task: [specific task]
+- Depends on: Phase 1
+
+### Phase 3: Synthesis
+- Combine results from Phase 2
+- Generate unified output
+
+## Coordination Rules
+
+1. **Plan before execute** - Create full execution plan first
+2. **Minimize handoffs** - Reduce context switching
+3. **Parallelize when possible** - Independent tasks in parallel
+4. **Clear boundaries** - Each agent has specific scope
+5. **Single source of truth** - One agent owns each artifact
+
+---
+
+**NOTE**: Complex tasks benefit from multi-agent orchestration. Simple tasks should use single agents directly.
