What it does
Review the configured cost alert rules and the alerts currently fired on the Agent Monitor dashboard, then explain exactly what tripped and why. Uses /api/alerts (fired feed) and /api/alerts/rules (definitions). Use when checking spend alerts or asking why a cost alarm went off.
Cost Alert
Audit the spend guardrails: which rules exist, which have fired, and what tripped them.
Input
The user provides: $ARGUMENTS
This may be empty (review everything), "unacked" (only unacknowledged alerts),
or a rule name to focus on.
Data Sources
| Endpoint | Returns |
|---|---|
GET /api/alerts/rules | { rules: [{ id, name, rule_type, config, enabled, cooldown_seconds }] }, the guardrail definitions |
GET /api/alerts | { alerts: [{ id, rule_id, rule_name, rule_type, session_id, agent_id, message, details, triggered_at, acked }], total, unacked, limit, offset }, the fired-alert feed, newest first. ?unacked=true filters to unacknowledged |
What the rule types mean
rule_type | config | Fires when |
|---|---|---|
token_threshold | { total_tokens } | A session's cumulative tokens (input + output + cache_read + cache_write) cross the ceiling, the spend-relevant guardrail |
event_pattern | { event_type?, tool_name?, summary_contains?, count?, window_minutes? } | Matching events reach count within the window |
inactivity | { minutes } | An active session goes quiet for minutes |
status_duration | { status, minutes } | An agent is stuck in working/waiting for minutes |
For cost work, focus on token_threshold. Translate its token ceiling to dollars using the blended rate from /api/pricing/cost (total_cost / total_tokens) so the user sees the alarm in money terms.
Report Sections
1. Configured guardrails
Table from /api/alerts/rules: name, type, the human-readable threshold (e.g. token_threshold → 12,500,000 tokens ≈ $50.0000), enabled state, cooldown. Flag rules that are disabled or have no spend-relevant guardrail at all.
