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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 |

How to install
mdr add hoangsonww/claude-code-agent-monitor/cost-alert@sha256:d4b015e991b4be9bThe line at the top of this page pins the label git:20260804.9eab0d7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
