| name | acceptance-pipeline-feature-design |
| description | Designs new features, extensions, or modifications to Uncle Bob's Acceptance Pipeline Specification — new mutation strategies, Gherkin syntax support, report formats, pipeline stages, IR fields, or handler patterns. Trigger when someone asks "how would I add X to the acceptance pipeline" or discusses spec-level changes to the parser, generator, runtime, mutator, or reporter components — even if they don't explicitly say "feature design." Works in tandem with the acceptance-pipeline-catalog skill, which provides the baseline spec reference. |
Acceptance Pipeline Feature Design
Guides agents through designing new features that extend Uncle Bob's Acceptance Pipeline Specification. Produces spec-quality output — language-neutral, implementation-agnostic, with precise behavioral requirements — that matches the style and rigor of the original spec.
This is a composition skill. It does not catalog what exists (that is acceptance-pipeline-catalog's job). Instead, it provides a structured workflow for designing what comes next.
When to Apply
- Designing a new mutation strategy, value type, or filter mechanism for the mutator
- Adding new Gherkin syntax support (data tables, tags, Rules keyword) to the parser
- Extending the JSON IR with new fields or objects
- Creating new report formats (HTML, JUnit XML) or output channels
- Adding new pipeline stages or operating modes (parallel runs, coverage filtering)
- Any spec-level change that affects multiple pipeline components (cross-cutting)
Prerequisite
Before using this skill, ensure acceptance-pipeline-catalog is available. That skill provides the baseline reference for the 9 required components, JSON IR schema, conformance checklist (21 items), and agent setup checklist (15 steps). This skill builds on top of that foundation.
Workflow Overview
The workflow has five phases, executed in order. Each phase builds on the output of the previous one — skipping phases produces incomplete or inconsistent designs.
