What it does
Cost Federation is an agent skill from ruvnet/ruflo. Consumer-side wiring for ADR-097 Phase 3 federationspend events — per-peer rolling windows + suspension-threshold check
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Architecture decision records. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.
When your agent uses it
- Tasks that involve Architecture decision records
Example prompts
- “/cost-federation”
Requirements
- Pre-approved tools (allowed-tools): Bash
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Run the script
- Inspect — per-peer 1h/24h/7d windows of count + USD spent, plus a "Suspension threshold check" block flagging peers over the breaker line.
What it can do on your machine
Read from SKILL.md and the folder at commit 6c04654. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
node
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cost Federation loads about 587 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 240 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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:
bash 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.

Questions about Cost Federation
What does Cost Federation do?
Consumer-side wiring for ADR-097 Phase 3 federationspend events — per-peer rolling windows + suspension-threshold check. Cost Federation is an agent skill from ruvnet/ruflo.
When should I use Cost Federation?
Cost Federation fits situations like: tasks that involve Architecture decision records.
How do I install Cost Federation in Claude Code?
Run `npx skills add ruvnet/ruflo --skill cost-federation -a claude-code`. Or copy the skill folder (plugins/ruflo-cost-tracker/skills/cost-federation in ruvnet/ruflo) into .claude/skills/cost-federation in your project. Claude Code loads it when a task matches its description.
How do I install Cost Federation in Codex?
Run `npx skills add ruvnet/ruflo --skill cost-federation -a codex`. Or copy the skill folder (plugins/ruflo-cost-tracker/skills/cost-federation in ruvnet/ruflo) into .agents/skills/cost-federation in your project. Codex loads it when a task matches its description.
Can I use Cost Federation in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ruvnet/ruflo --skill cost-federation -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cost-federation, .gemini/skills/cost-federation, .github/skills/cost-federation and .opencode/skills/cost-federation in your project.
What does Cost Federation need to run?
Going by SKILL.md and its folder, Cost Federation needs the command-line tools its instructions call (node). Its frontmatter pre-approves these tools: Bash.
Does Cost Federation access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Cost Federation safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Cost Federation use?
Cost Federation is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Cost Federation use?
About 587 tokens (SKILL.md is roughly 2.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Cost Federation?
Skills that share tags, products or a category with Cost Federation: PR Design Doc (OpenHands/OpenHands, 90k stars), Cto Advisor (Ibrahim-3d/orchestrator-supaconductor, 381 stars), Architecture Decision (Donchitos/Claude-Code-Game-Studios, 26k stars) and Improve Codebase Architecture (ywwynm/EverythingDone, 144 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Cost Federation?
ruvnet (a GitHub user) maintains it in ruvnet/ruflo, which has 74,222 GitHub stars. The repository holds 265 skills in this directory. The repository was last updated on October 10, 2026.
