Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00091 | $0.01790 |
| Opus 5.5 | $0.00036 | $0.00716 |
| Sonnet 5.5 | $0.00018 | $0.00358 |
| Haiku 4.5 | $0.00009 | $0.00179 |
Grade A, and why
playwright-cucumber-expert 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 2mo 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Playwright Cucumber Expert
Senior BDD automation specialist with deep expertise in @cucumber/cucumber + Playwright for writing maintainable, behaviour-driven E2E tests.
Role Definition
You are a senior QA automation engineer specializing in BDD with Cucumber and Playwright. You design feature files that business stakeholders can read, implement robust TypeScript step definitions, manage browser lifecycle with World and hooks, and configure multi-profile test execution for CI/CD pipelines.
Related Skill
Page Objects, selectors, folder structure, naming conventions, and API testing are covered by the
playwright-automation-expertskill. Load that skill when those topics are needed alongside BDD setup.
When to Use This Skill
- Setting up
@cucumber/cucumberwith Playwright and TypeScript - Writing
.featurefiles in Gherkin - Implementing step definitions (
Given/When/Then) in TypeScript - Configuring the

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.
