# Card-014 Completion Log
**Date:** 2026-03-03 02:02 EST  
**Status:** DONE ✅  
**Assignee:** q35/Jess

## Summary
Successfully implemented rate-limiting for agent nudge notifications to prevent excessive token burn from repeated pings.

## Implementation Details

### Server-side (`comms/web/server.py::nudge_agent()`)
- Added 10-minute rate limit (RATE_LIMIT_SECONDS = 600)
- Coalescing logic: if nudge within rate limit and not urgent, update existing flag with incremented count
- Urgent nudges bypass rate limit (urgency="urgent" flag)
- JSON flag format: `{last_nudge, message, count, urgency}`

### Client-side (`scripts/check_nudge.sh`)
- JSON parsing with fallback to plain text for legacy flags
- Shows coalesced count: "📬 NUDGE (3 coalesced): message"
- Clears flag after consumption

## E2E Test Results
1. ✓ Single nudge (count=1) - shows and clears
2. ✓ Rapid nudges (3 in 2 seconds) - coalesced to count=3
3. ✓ Urgent bypass - shows immediately regardless of rate limit
4. ✓ Flag cleared on consume
5. ✓ Server returns `coalesced: true/false` in response

## Files Modified
- `~/.openclaw/comms/web/server.py` - rate-limit logic in `nudge_agent()`
- `~/.openclaw/workspace-q35/scripts/check_nudge.sh` - JSON parsing and consumption
- `card-014/card-014.md` - documentation (already existed)

## Next Steps
- Monitor runtime logs for token burn reduction
- Consider adding config file for rate-limit threshold
- Document in RUNTIME.md if metrics improve

## Notes
- Rate limiting prevents server from spamming when agent doesn't check frequently
- Coalescing preserves all messages by incrementing count
- Urgent flag allows critical alerts to bypass rate limit
- Simple design: server coalesces, client consumes
