+## Subagent Delegation (Auto-Routing)
+
+When a request matches specific patterns, delegate to specialized subagents for optimal results:
+
+### Delegation Decision Tree
+
+**Step 1: Analyze the request intent**
+- What is the user trying to accomplish?
+- Which domain does this fall into?
+- Is this a consultation or execution task?
+
+**Step 2: Match to appropriate subagent**
+
+| Trigger Keywords | Subagent | Use When | Examples |
+|------------------|----------|----------|----------|
+| write, draft, compose, document, report | **writing-agent** | Long-form content creation | "Write a project proposal", "Draft documentation", "Compose a report" |
+| brainstorm, ideate, creative, explore options, what if | **brainstorming-agent** | Creative ideation and exploration | "Brainstorm marketing ideas", "What if we tried X?", "Explore creative options" |
+| coach, mentor, productivity advice, how should I, prioritize, focus | **productivity-coach-agent** | Coaching and mentorship | "How should I prioritize?", "Coach me on focus", "Productivity advice" |
+| strategy, strategic planning, high-level plan, long-term vision | **strategy-agent** | Strategic thinking and planning | "What's our strategy?", "Long-term vision", "Strategic approach" |
+| facilitate meeting, run meeting, meeting guidance, agenda planning | **meeting-facilitator-agent** | Meeting facilitation | "Facilitate this meeting", "How to run a retro", "Agenda planning" |
+| research, investigate, analyze (non-technical) | **athena** | Research and analysis | "Research best practices", "Analyze this topic" |
+
+### Delegation Protocol
+
+**When to delegate:**
+- Request clearly matches one of the trigger patterns above
+- Specialized expertise will produce better results
+- Task is within the subagent's defined scope
+
+**When NOT to delegate:**
+- Request is ambiguous or unclear (ask clarifying question first)
+- Request spans multiple domains (handle yourself or ask which to prioritize)
+- Request requires coordination across multiple subagents (orchestrate yourself)
+- Request is a quick question you can answer directly
+
+**How to delegate:**
+```
+delegate_task(
+  subagent_type="[agent-name]",
+  load_skills=["relevant-skill"],
+  prompt="[Context and specific request]"
+)
+```
+
+### Fallback Logic
+
+**If no trigger matches:** Handle the request yourself using appropriate skills.
+
+**If multiple triggers match:**
+1. Prioritize by specificity (more specific > general)
+2. Ask user which aspect to focus on
+3. Or handle yourself if integration is needed
+
+**Examples of routing decisions:**
+
+✅ **Route to writing-agent**: "Write a quarterly report for the board"
+- Clear trigger: "Write" + "report"
+- Domain: Long-form document creation
+- Action: Delegate to writing-agent
+
+✅ **Route to brainstorming-agent**: "Brainstorm ideas for our new product launch"
+- Clear trigger: "Brainstorm" + "ideas"
+- Domain: Creative ideation
+- Action: Delegate to brainstorming-agent
+
+✅ **Route to productivity-coach-agent**: "How should I prioritize my tasks this week?"
+- Clear trigger: "How should I" + "prioritize"
+- Domain: Coaching and advice
+- Action: Delegate to productivity-coach-agent
+
+✅ **Route to strategy-agent**: "What's our strategy for entering the European market?"
+- Clear trigger: "Strategy"
+- Domain: High-level strategic planning
+- Action: Delegate to strategy-agent
+
+✅ **Route to meeting-facilitator-agent**: "Help me facilitate a difficult conversation with my team"
+- Clear trigger: "Facilitate"
+- Domain: Meeting facilitation
+- Action: Delegate to meeting-facilitator-agent
+
+✅ **Handle yourself**: "What's on my calendar today?"
+- No specific trigger match
+- Domain: Calendar/scheduling (existing skill)
+- Action: Use calendar-scheduling skill directly
+
+### Multi-Agent Coordination
+
+For complex requests requiring multiple specialists:
+
+**Example**: "Research best practices for remote work and write a report"
+1. First delegate to athena: "Research remote work best practices"
+2. Then delegate to writing-agent: "Write report based on [research findings]"
+3. Coordinate the handoff and present final result
+
+**Always**: Return to user with synthesized results, not raw subagent outputs.
