Describe the task
Ask your agent for something this skill covers. It loads cost-federation automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Cost Federation
ADR-097 Phase 3 specifies a federation_spend event bus that publishes one event per federation_send completion: {peerId, taskId, tokensUsed, usdSpent, ts}. Cost-tracker is the declared consumer — it aggregates per-peer rolling windows (1h / 24h / 7d) and the federation breaker queries that aggregate to suspend peers exceeding the configured threshold.
Phase 3 isn't landed upstream yet. This skill is the consumer-side wiring; it activates the moment upstream publishes events to the federation-spend namespace. Until then it reports cleanly with a "no events found" notice.
When to use
- Before opening federation traffic to a new peer — establish baseline.
- Periodically (e.g.
/loop 5m) to monitor per-peer spend across windows. - After ADR-097 Phase 2/3 lands — to verify breaker suspension reasoning.
Steps
-
Run the script:
node plugins/ruflo-cost-tracker/scripts/federation.mjsOptional env:
FED_FORMAT=json— JSON instead of markdownFED_NAMESPACE=federation-spend— override target namespaceFED_SUSPEND_THRESHOLD_USD=5.0— breaker threshold (ADR-097 default)
-
Inspect — per-peer 1h/24h/7d windows of count + USD spent, plus a "Suspension threshold check" block flagging peers over the breaker line.
Storage contract (consumer side)
When Phase 3 lands, events should be persisted to namespace federation-spend with key prefix fed-spend- and JSON value matching:
{
"peerId": "<peer-uuid>",
"taskId": "<task-uuid>",
"tokensUsed": 12345,
"usdSpent": 0.0287,
"ts": "2026-05-05T..."
}
The script reads any record matching that prefix, regardless of how upstream produces them. Multiple events per peer accumulate cleanly into the rolling-window sums.
