Plan A Feature

Category: Product  ·  Sub-category: prd-spec  ·  Last updated:
Builds a feature specification from scratch through a relentless, evidence-based interview that walks the design tree decision-by-decision, resolving dependencies as it goes. Use when the user wants to plan, design, scope, specify, or flesh out a new feature, capability, or system behavior before implementation — including requests like "help me plan X", "spec out this feature", "design the Y flow", or "let's figure out what it should do". Explores the codebase, project documentation, coding standards, and ADRs to resolve questions before asking the user, and always offers a recommended answer when questions must be surfaced. Produces a feature-specification.md focused on system behaviors, coordinations, processes, and user interactions — not implementation detail. Does not refine or stress-test an existing plan — use iterative-plan-review. Does not investigate bugs or failures — use investigate. Does not analyze existing architecture — use architectural-analysis. Does not document already-built features — use project-documentation. Does not record architectural decisions — use architectural-decision-record.
