+---
+
+# Note Skill
+
+Save important context to `.omx/notepad.md` that survives conversation compaction.
+
+## Usage
+
+| Command | Action |
+|---------|--------|
+| `/note <content>` | Add to Working Memory with timestamp |
+| `/note --priority <content>` | Add to Priority Context (always loaded) |
+| `/note --manual <content>` | Add to MANUAL section (never pruned) |
+| `/note --show` | Display current notepad contents |
+| `/note --prune` | Remove entries older than 7 days |
+| `/note --clear` | Clear Working Memory (keep Priority + MANUAL) |
+
+## Sections
+
+### Priority Context (500 char limit)
+- **Always** injected on session start
+- Use for critical facts: "Project uses pnpm", "API in src/api/client.ts"
+- Keep it SHORT - this eats into your context budget
+
+### Working Memory
+- Timestamped session notes
+- Auto-pruned after 7 days
+- Good for: debugging breadcrumbs, temporary findings
+
+### MANUAL
+- Never auto-pruned
+- User-controlled permanent notes
+- Good for: team contacts, deployment info
+
+## Examples
+
+```
+/note Found auth bug in UserContext - missing useEffect dependency
+/note --priority Project uses TypeScript strict mode, all files in src/
+/note --manual Contact: api-team@company.com for backend questions
+/note --show
+/note --prune
+```
+
+## Behavior
+
+1. Creates `.omx/notepad.md` if it doesn't exist
+2. Parses the argument to determine section
+3. Appends content with timestamp (for Working Memory)
+4. Warns if Priority Context exceeds 500 chars
+5. Confirms what was saved
+
+## Integration
+
+Notepad content is automatically loaded on session start:
+- Priority Context: ALWAYS loaded
+- Working Memory: Loaded if recent entries exist
+
+This helps survive conversation compaction without losing critical context.
