Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/ruvnet/ruflo --skill cost-export- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads cost-export automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Cost Export
Pulls every session-* and budget-config-* record from cost-tracking and emits in formats consumable by external observability systems. Without this, cost data lives only inside the AgentDB namespace; with it, the same data lights up dashboards.
When to use
- After any cost-track run, to refresh metrics for Grafana / Datadog / Prometheus.
- Cron-friendly via
/loop 5mto keep external dashboards near-real-time. - One-shot to a webhook for ad-hoc reporting (Slack, custom endpoint).
Steps
-
Pick a format — textfile collector for Prometheus / Grafana, or webhook POST for everything else:
# Prometheus node_exporter textfile collector node plugins/ruflo-cost-tracker/scripts/export.mjs --prometheus /var/lib/node_exporter/textfile_collector/cost_tracker.prom # Webhook (POSTs JSON; add auth via env) EXPORT_WEBHOOK_HEADER='Authorization: Bearer $TOKEN' \ node plugins/ruflo-cost-tracker/scripts/export.mjs --webhook https://hooks.example.com/cost-tracker # Stdout JSON (default if no flag) node plugins/ruflo-cost-tracker/scripts/export.mjs -
Inspect what's emitted — Prometheus output includes:
cost_tracker_total_usd <gauge> cost_tracker_tier_total_usd{tier="opus|sonnet|haiku"} <gauge> cost_tracker_session_total_usd{session="<8-char>"} <gauge> cost_tracker_session_messages{session="<8-char>"} <counter> cost_tracker_budget_usd <gauge> (if budget configured) cost_tracker_budget_utilization <gauge> (spent / budget) -
Webhook payload shape — the JSON the webhook receives matches the stdout JSON:
{ exportedAt, sessions: [...], budget, totalUsd, byTier }. Headers may be added viaEXPORT_WEBHOOK_HEADER='K1: V1, K2: V2'(comma-separated).
Env overrides
| Env | Default | Purpose |
|---|---|---|
EXPORT_NAMESPACE | cost-tracking | Override target namespace |
EXPORT_WEBHOOK_HEADER | unset | Comma-separated K: V pairs for webhook auth |
EXPORT_QUIET=1 | unset | Suppress non-error confirmation output |
