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 | $0.00060 | $0.00795 |
| Opus 5 | $0.00030 | $0.00398 |
| Sonnet 5 | $0.00012 | $0.00159 |
| Haiku 4.5 | $0.00006 | $0.00080 |
Grade A, and why
expo-cicd-workflows 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 9d 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.
This is a copy
95% identical to expo-cicd-workflows — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reference Documentation
Fetch these resources before generating or validating workflow files. Use the fetch script (implemented using Node.js) in this skill's scripts/ directory; it caches responses using ETags for efficiency:

JSON Schema — https://api.expo.dev/v2/workflows/schema
- It is NECESSARY to fetch this schema
- Source of truth for validation
- All job types and their required/optional parameters
- Trigger types and configurations
- Runner types, VM images, and all enums

Syntax Documentation — https://raw.githubusercontent.com/expo/expo/refs/heads/main/.agents/docs/pages/eas/workflows/syntax.mdx

Pre-packaged Jobs — https://raw.githubusercontent.com/expo/expo/refs/heads/main/.agents/docs/pages/eas/workflows/pre-packaged-jobs.mdx
- Documentation for supported pre-packaged job types
- Job-specific parameters and outputs
Do not rely on memorized values; these resources evolve as new features are added.
Workflow File Location
Workflows live in .eas/workflows/*.yml (or .yaml).
Top-Level Structure
A workflow file has these top-level keys:
name— Display name for the workflowon— Triggers that start the workflow (at least one required)jobs— Job definitions (required)defaults— Shared defaults for all jobsconcurrency— Control parallel workflow runs
Consult the schema for the full specification of each section.
Expressions
Use ${{ }} syntax for dynamic values. The schema defines available contexts:
github.*— GitHub repository and event informationinputs.*— Values fromworkflow_dispatchinputsneeds.*— Outputs and status from dependent jobsjobs.*— Job outputs (alternative syntax)steps.*— Step outputs within custom jobsworkflow.*— Workflow metadata
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

expo-cicd-workflows is a skill published in the GitHub repository mtnyilmaz/agents (6 stars, last pushed 3mo ago), licensed MIT. It adds 60 tokens to every session and 795 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to expo-cicd-workflows, differing in 4 lines, and is treated as a copy.
