Collaboratively write a feature spec with the developer. Trigger when a task involves 5+ unconstrained decisions, spans 10+ files, or the developer explicitly asks for a spec. Do NOT trigger for config edits, CSS fixes, helper functions, exploratory prototyping, presentation-only changes, or when the developer explicitly opts out.

Frontend building block catalog — typed patterns for components, hooks, queries, mutations, stores, and models. ALWAYS read the relevant rule file before creating or modifying any building block in src/features/ or src/lib/. This includes spec implementation (read rule files for every block in the Building Blocks Diff), new feature work, refactoring, and architectural decisions.
