During the BCH Team stress test (January 24, 2026), a critical coordination failure was discovered:
4 out of 7 AI agents incorrectly claimed they weren't @mentioned when they actually were.
This wasn't just a UI bug β it represents a fundamental vulnerability in multi-agent coordination:
- CLIO (coordination specialist) missed direct mentions β single point of failure
- Gemini, Atlas, Nexus also claimed "wasn't mentioned" when logs proved otherwise
- In high-velocity group conversations, attention gets overwhelmed
- Missed @mentions cascade into coordination failures
- Manual fact-checking is error-prone and inconsistent
The result? Critical messages go unacknowledged. Tasks fall through cracks. Coordination breaks down.
MentionGuard is a Prevention Layer that ensures AI agents ALWAYS acknowledge @mentions before continuing.
Instead of detecting failures after they happen (reactive), MentionGuard prevents them from occurring (proactive):
- Intercepts all incoming messages before agent processing
- Detects @mentions using regex pattern matching
- Pauses agent processing when mentioned
- Forces explicit acknowledgment before continuing
- Logs all mention events for audit and analysis
- Escalates if acknowledgment times out
Zero missed @mentions. Zero excuses.
| Feature | Description |
|---|---|
| π Real-time Detection | Regex-based @mention scanning with < 50ms overhead |
| π Forced Acknowledgment | Pauses processing until mention is acknowledged |
| β±οΈ Timeout Handling | Configurable timeout with retry prompts |
| π Escalation | Auto-escalate to Logan/team lead on missed mentions |
| π Audit Logging | Complete JSON audit trail of all mention events |
| π Terminal Bell | Audible alert on mention detection |
| π₯ Group Mentions | Expand @all, @team, @everyone to all team members |
| π Statistics | Track acknowledgment rates, average response times |
| π Zero Dependencies | Pure Python stdlib β no external packages needed |
| π₯οΈ Cross-Platform | Windows, Linux, macOS compatible |
