Use when implementing, reviewing, or debugging a Gherkin acceptance-test pipeline with mutation testing. Covers parser, JSON IR, generator, runtime, step handlers, test runner, mutator, value mutation rules, execution, result classification, reporting, project layout, conformance, and agent setup. Based on Uncle Bob's Acceptance Pipeline Specification. Trigger even when the user mentions Gherkin parsing, acceptance test generation, mutation testing for acceptance tests, or building a portable test pipeline.
Why this skill is useful
Adds detailed specifications and rules for implementing a Gherkin acceptance-test pipeline, including executable examples and mutation testing procedures.

What this skill does
Robert C. Martin Acceptance Pipeline Best Practices Language-neutral specification for a portable acceptance-test pipeline: Gherkin feature files to JSON IR to generated acceptance tests to mutation testing. Based on Robert C. Martin's Acceptance Pipeline Specification. Contains ~50 rules across 14 categories, prioritized by impact. When to Apply Reference these rules when: Building a Gherkin parser that outputs JSON IR Implementing an acceptance test generator from JSON IR Writing an acceptance runtime that expands scenarios and dispatches steps Implementing mutation testing for acceptance test example values Setting up the full pipeline (parser, generator, runner, mutator) in a new project Debugging pipeline failures (parse errors, generation issues, mutation classification) Pipeline Overview The pipeline has two modes: Normal acceptance run: Mutation run: The normal run proves the project satisfies the feature. The mutation run probes whether tests are strong enough to fail when example data changes.
