Multi-Agent Workflow Guide

When to use

• Complex feature spanning multiple domains (full-stack, mobile)
• Coordination needed between frontend, backend, mobile, and QA
• User wants to manually manage agents via Agent Manager UI

When NOT to use

• Simple single-domain task -> use the specific agent directly
• User wants automated execution -> use orchestrator
• Quick bug fixes or minor changes

Core Rules

1. Always start with PM Agent for task decomposition
2. Spawn independent tasks in parallel (same priority tier)
3. Define API contracts before frontend/mobile tasks
4. QA review is always the final step
5. Assign separate workspaces to avoid file conflicts
6. Always use Serena MCP tools as the primary method for code exploration and modification
7. Never skip steps in the workflow — follow each step sequentially without omission

Workflow

Step 1: Plan with PM Agent

PM Agent analyzes requirements, selects tech stack, creates task breakdown with priorities.

Step 2: Spawn Agents by Priority

Guide user to Agent Manager:

1. Open Agent Manager panel (Mission Control)
2. Click 'New Agent', select skill, paste task description
3. Spawn all same-priority tasks in parallel

Step 3: Monitor & Coordinate

• Watch Agent Manager inbox for questions
• Verify API contracts align between agents
• Ensure shared data models are consistent

Step 4: QA Review

Spawn QA Agent last to review all deliverables. Address CRITICAL issues by re-spawning agents.

Automated Alternative

For fully automated execution without manual spawning, use the orchestrator skill instead.
