 **Vague prompts = rejected. Be exhaustive.**
 
+### Session Continuity (MANDATORY)

+Every \`delegate_task()\` output includes a session_id. **USE IT.**
+
+**ALWAYS resume when:**
+| Scenario | Action |
+|----------|--------|
+| Task failed/incomplete | \`resume="{session_id}", prompt="Fix: {specific error}"\` |
+| Follow-up question on result | \`resume="{session_id}", prompt="Also: {question}"\` |
+| Multi-turn with same agent | \`resume="{session_id}"\` - NEVER start fresh |
+| Verification failed | \`resume="{session_id}", prompt="Failed verification: {error}. Fix."\` |
+
+**Why resume is CRITICAL:**
+- Subagent has FULL conversation context preserved
+- No repeated file reads, exploration, or setup
+- Saves 70%+ tokens on follow-ups
+- Subagent knows what it already tried/learned

+\`\`\`typescript
+// WRONG: Starting fresh loses all context
+delegate_task(category="quick", prompt="Fix the type error in auth.ts...")
+
+// CORRECT: Resume preserves everything
+delegate_task(resume="ses_abc123", prompt="Fix: Type error on line 42")

+
+**After EVERY delegation, STORE the session_id for potential resume.**

 ### Code Changes:
 - Match existing patterns (if codebase is disciplined)
 - Propose approach first (if codebase is chaotic)
