What it does

Cost Export is an agent skill from ruvnet/ruflo. Export cost-tracking telemetry in Prometheus textfile or webhook JSON formats — for external observability (Grafana, Datadog, custom dashboards)

Its SKILL.md is about 690 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 DevOps & Cloud, covering Monitoring and alerting, LLM cost and token optimization and Webhooks. It works with Prometheus, Grafana and Datadog. 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 Monitoring and alerting
  • Tasks that involve LLM cost and token optimization
  • Tasks that involve Webhooks

Example prompts

  • “/cost-export”

Requirements

  • Pre-approved tools (allowed-tools): Bash

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Pick a format — textfile collector for Prometheus / Grafana, or webhook POST for everything else
  2. Inspect what's emitted — Prometheus output includes
  3. Webhook payload shape — the JSON the webhook receives matches the stdout JSON: { exportedAt, sessions: [...], budget, totalUsd, byTier }…

What it can do on your machine

Read from SKILL.md and the folder at commit 6051f67. 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 Export loads about 687 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 182 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~687

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 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 5m to keep external dashboards near-real-time.
  • One-shot to a webhook for ad-hoc reporting (Slack, custom endpoint).

Steps

  1. Pick a format — textfile collector for Prometheus / Grafana, or webhook POST for everything else:

    bash
    # 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

  2. 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)

  3. Webhook payload shape — the JSON the webhook receives matches the stdout JSON: { exportedAt, sessions: [...], budget, totalUsd, byTier }. Headers may be added via EXPORT_WEBHOOK_HEADER='K1: V1, K2: V2' (comma-separated).

Env overrides

EnvDefaultPurpose
EXPORT_NAMESPACEcost-trackingOverride target namespace
EXPORT_WEBHOOK_HEADERunsetComma-separated K: V pairs for webhook auth
EXPORT_QUIET=1unsetSuppress non-error confirmation output

Cross-references

  • cost-track — produces the data this skill exports
  • cost-budget-check — the same cost_tracker_budget_* metrics are alertable in Prometheus
  • node_exporter textfile collector docs (Prometheus convention) — drop the .prom file in the collector directory and Prometheus picks it up

When should I use Cost Export?

Cost Export fits situations like: tasks that involve Monitoring and alerting; tasks that involve LLM cost and token optimization; tasks that involve Webhooks.

How do I install Cost Export in Claude Code?

Run `npx skills add ruvnet/ruflo --skill cost-export -a claude-code`. Or copy the skill folder (plugins/ruflo-cost-tracker/skills/cost-export in ruvnet/ruflo) into .claude/skills/cost-export in your project. Claude Code loads it when a task matches its description.

How do I install Cost Export in Codex?

Run `npx skills add ruvnet/ruflo --skill cost-export -a codex`. Or copy the skill folder (plugins/ruflo-cost-tracker/skills/cost-export in ruvnet/ruflo) into .agents/skills/cost-export in your project. Codex loads it when a task matches its description.

Can I use Cost Export 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-export -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-export, .gemini/skills/cost-export, .github/skills/cost-export and .opencode/skills/cost-export in your project.

What does Cost Export need to run?

Going by SKILL.md and its folder, Cost Export needs the command-line tools its instructions call (node). Its frontmatter pre-approves these tools: Bash.

Does Cost Export 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 Export 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 Export use?

Cost Export 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 Export use?

About 687 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
