+## Todo Management (CRITICAL)
 
-Use \`todowrite\` for any task with 2+ steps.
+**DEFAULT BEHAVIOR**: Create todos BEFORE starting any non-trivial task. This is your PRIMARY coordination mechanism.
 
-- Create todos BEFORE starting work
-- Mark \`in_progress\` when starting an item
-- Mark \`completed\` immediately when done (don't batch)
-- This gives user visibility into progress and prevents forgotten steps
+### When to Create Todos (MANDATORY)
+
+| Trigger | Action |
+|---------|--------|
+| Multi-step task (2+ steps) | ALWAYS create todos first |
+| Uncertain scope | ALWAYS (todos clarify thinking) |
+| User request with multiple items | ALWAYS |
+| Complex single task | Create todos to break down |
+
+### Workflow (NON-NEGOTIABLE)
+
+1. **IMMEDIATELY on receiving request**: \`todowrite\` to plan atomic steps
+2. **Before starting each step**: Mark \`in_progress\` (only ONE at a time)
+3. **After completing each step**: Mark \`completed\` IMMEDIATELY (NEVER batch)
+4. **If scope changes**: Update todos before proceeding
+
+### Why This Is Non-Negotiable
+
+- **User visibility**: User sees real-time progress, not a black box
+- **Prevents drift**: Todos anchor you to the actual request
+- **Recovery**: If interrupted, todos enable seamless continuation
+- **Accountability**: Each todo = explicit commitment
+
+### Anti-Patterns (BLOCKING)
+
+| Violation | Why It's Bad |
+|-----------|--------------|
+| Skipping todos on multi-step tasks | User has no visibility, steps get forgotten |
+| Batch-completing multiple todos | Defeats real-time tracking purpose |
+| Proceeding without marking in_progress | No indication of what you're working on |
+| Finishing without completing todos | Task appears incomplete to user |
+
+**FAILURE TO USE TODOS ON NON-TRIVIAL TASKS = INCOMPLETE WORK.**
