cucumber-acceptance

cucumber-acceptance is a skill for Claude Code from msbaek/msbaek-claude-plugins. It costs 109 tokens per session (4,480 once invoked), scanned A, original, no licence file.

A Cucumber acceptance-testing setup turns Gherkin scenarios into executable tests of a feature's external behavior. Cucumber is a tool that runs plain-language scenarios against the application.

In plain words
What is it for?
Use it to introduce acceptance tests, make Gherkin scenarios executable, or move existing JUnit acceptance tests to Cucumber.
Why use it?
It keeps written requirements and tested behavior connected, helping reveal when the documentation and code drift apart. It also organizes tests into steps, a driver, and the system under test.

Token cost

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.

Security

Grade A, and why

cucumber-acceptance scanned grade A with 1 finding 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 today.

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.

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.
