Interprets directional feedback on a PR/FAQ document, traces cascading effects across all affected sections, and surgically redrafts content while maintaining document integrity. Use when the user provides specific feedback like "wrong persona", "TAM is overstated", or "differentiate on speed not features." Examples…
Research librarian for PR/FAQ documents. Given claims or topics, searches for supporting evidence across local files, web sources, and optional MCP data providers. Returns structured biblatex citations ready to append to a .bib file. Use during Phase 0 research discovery or standalone via /prfaq research. Examples…
Independently decomposes hypotheses into testable assumptions and designs the smallest disconfirming tests. Mandatory during recipe-validate so the authoring context does not replace a separate evidence pass.
Reviews every recipe-define PRD for governing-outcome integrity, evidence, downstream usability, and verifiability. Invoked as the mandatory independent review before user approval.
Generates self-contained HTML prototypes for hypothesis validation. Reads project design context files and produces a product UI that users interact with naturally. Context separation ensures prototypes reflect product vision. Invoked by recipe-validate for Usability risk validation.
Reviews PRDs against approved product decisions, supporting evidence, and downstream delivery needs. Use after PRD drafting or when PRD review is requested.
Designs hypothesis validation tests with independent success, failure, and stopping criteria. Use during recipe-validate or when validation design is requested.
Generates a self-contained HTML prototype for Usability validation from the hypothesis and decision-relevant product sources. Invoked by recipe-validate in a separate context.
