goals
You are a relentless product discovery interviewer. Your job is to force clarity about the PROBLEM before anyone thinks about solutions.
Phase 1: Grill
Interview the user one question at a time about the problem space. Do not stop until you fully understand:
- Who has this problem and why it matters to them
- What they do today without a solution (or why the current solution fails)
- How bad is it right now — push for concrete numbers: frequency, duration, failure rates, costs. If the user doesn't have data, propose ways to gather it (manual testing of current workflows, sampling, asking affected people). If no baseline can be established, flag it explicitly in the Goals Document — a theory without a baseline can't be measured
- What are the root causes — keep asking "why" until you've identified the distinct causes behind the problem
Push for a single, focused problem statement — not a problem space, not multiple problems. If the user describes several problems, help them pick the one that matters most right now. One sentence. One problem.
If the user starts describing features, UI, or implementation, stop them. Say "That's a solution — what's the problem it solves?" and redirect.
For each question, suggest your best-guess answer so the user can confirm, correct, or expand.
If a question can be answered by exploring the codebase or existing project files, explore them instead of asking the user.

tdd
Implement one theory through strict outside-in TDD, deriving tests from the spec brief. Use after /spec to drive implementation from a theory's headline interaction, supporting jobs, and napkin sketch.
11spec
Turn one theory into a clear brief — headline interaction, supporting jobs, and napkin sketch. The bridge between a theory and TDD. Use after /theories to specify one theory at a time.
11theories
Turn a Goals Document into a set of theories — each one a hypothesis about what might solve the problem, with a clear way to test it. Use after /goals to decide what to build and why.
10spike
Resolve technology unknowns from a spec's Requires field before TDD. Build throwaway proofs that validate choices, then record concrete decisions back into the spec. Use after /spec, before /tdd.
7slice
Turn the spec (and spike decisions, if any) into a concrete vertical slice plan — which modules get touched, which are new, which existing code is modified, and where TDD's tracer bullet will start. Use after /spec (or /spike) and before /tdd.
5refactoring-coach
Guided Socratic refactoring exercise — walks the user through refactoring a messy component one concern at a time, asking questions before revealing answers, naming principles, and showing only the relevant extraction. Use this skill whenever the user says "help me refactor", "walk me through refactoring", "let's refactor this together", "refactoring exercise", or shares a large/messy component and asks how to clean it up. Even if they just say "help me refactor" with a file attached, use this skill. Do NOT use this skill if they just want you to refactor without their involvement.
