Refinery

Unified specification refinement plugin. Single entry point for all spec operations: greenfield architecture pipelines (principles → design → stack → spec → plan), feature spec creation in existing systems, iterative convergence loops, quality reviews, drift detection, finalization, ticket decomposition, traceable updates, and lifecycle archival. Detects pipeline state from existing artifact frontmatter and routes intelligently. Use whenever you need to create, refine, validate, or evolve a technical specification.

Core reference for EARS requirement patterns, Given/When/Then acceptance criteria, RFC 2119 language, requirement ID conventions, and specification quality checklists. Background knowledge for the spec-writer agent. Preloaded by spec-writer via the skills frontmatter field; not user-invocable.
