Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 10 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.01447 |
| Opus 5 | $0.00020 | $0.00724 |
| Sonnet 5 | $0.00008 | $0.00289 |
| Haiku 4.5 | $0.00004 | $0.00145 |
Grade A, and why
output-dev-workflow-cost scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Workflow Run Cost
Overview
This skill helps you calculate the cost of a completed workflow execution using the Output CLI. It breaks down costs by LLM model (token usage) and external API service calls.
When to Use This Skill
- Checking how much a workflow run cost in LLM tokens
- Analyzing API service spend per workflow execution
- Comparing costs between workflow runs
- Presenting cost data during a demo or review
Step 1: Get a Workflow Run ID
The workflow cost command requires a workflow run ID — not the workflow name.
A run ID looks like: process_transcripts_2026-03-23T19:35:17.000Z_c2biRk_F9rYktF-wagBf5
If you already have a run ID, skip to Step 2.
If you don't have a run ID:
Option A — List recent runs (use skill: output-workflow-runs-list):
npx output workflow runs list <workflowName> --limit 5
Copy the run ID from the most recent completed run.
Option B — Run the workflow now and capture the ID:
If you know the input, run it synchronously and the run ID will be in the output:
npx output workflow run <workflowName> --input '{"key": "value"}'
Or asynchronously (use skill: output-workflow-start):
npx output workflow start <workflowName> --input '{"key": "value"}'
# Returns: Workflow ID: <runId>
If you don't know the input, check for a scenario file (use skill: output-dev-scenario-file) or the workflow's inputSchema in its types.ts.
Note: The workflow name (e.g.
process_transcripts) identifies the workflow type. The workflow run ID (e.g.process_transcripts_2026-03-23T19:35:17.000Z_abc123) identifies a specific execution.workflow costrequires the run ID.
Step 2: Calculate the Cost
Basic usage (text output):
npx output workflow cost <runId>
With a local trace file:
npx output workflow cost <runId> path/to/trace.json
JSON output (for programmatic use or display):
npx output workflow cost <runId> --json
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

output-dev-workflow-cost is a skill published in the GitHub repository growthxai/output (435 stars, last pushed 3d ago), licensed Apache-2.0. It adds 40 tokens to every session and 1,447 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
