A single misconfigured agent—or an enthusiastic intern leaving a loop running—can turn a predictable $4K monthly AI bill into a five-figure surprise. Traditional cloud alerts don't cover IDE-embedded tools or personal API keys rolled into org billing.
Alert types worth enabling
- Monthly budget thresholds at 70%, 90%, and 100% with Slack or email routing
- Daily spike detection when spend exceeds 2× trailing seven-day average
- Per-developer caps for trial accounts or contractors
- Model-specific alerts when premium model share crosses a policy limit
Response playbook
- Identify the team/repo driving the spike within minutes—not at month close
- Pause or throttle non-production API keys if policy allows
- Coach on agent loop patterns (retry limits, max iterations)
- Document the incident for the next vendor negotiation
