kata-discuss-phase

<objective> Extract implementation decisions that downstream agents need — researcher and planner will use CONTEXT.md to know what to investigate and what choices are locked.

1. Analyze the phase to identify gray areas (UI, UX, behavior, etc.)
2. Present gray areas — user selects which to discuss
3. Deep-dive each selected area until satisfied
4. Create CONTEXT.md with decisions that guide research and planning

<context> Phase number: $ARGUMENTS (required) <process> 1. Validate phase number (error if missing or not in roadmap) 2. Check if CONTEXT.md exists (offer update/view/skip if yes) 3. **Analyze phase** — Identify domain and generate phase-specific gray areas 4. **Present gray areas** — Multi-select: which to discuss? (NO skip option) 5. **Deep-dive each area** — 4 questions per area, then offer more/next 6. **Write CONTEXT.md** — Sections match areas discussed 7. Offer next steps (research or plan)

• Phase boundary from ROADMAP.md is FIXED
• Discussion clarifies HOW to implement, not WHETHER to add more
• If user suggests new capabilities: "That's its own phase. I'll note it for later."
• Capture deferred ideas — don't lose them, don't act on them

• Something users SEE → layout, density, interactions, states
• Something users CALL → responses, errors, auth, versioning
• Something users RUN → output format, flags, modes, error handling
• Something users READ → structure, tone, depth, flow
• Something being ORGANIZED → criteria, grouping, naming, exceptions

• Ask 4 questions per area before checking
• "More questions about [area], or move to next?"
• If more → ask 4 more, check again
• After all areas → "Ready to create context?"

• Technical implementation
• Architecture choices
• Performance concerns
• Scope expansion </process>

• Gray areas identified through intelligent analysis
• User chose which areas to discuss
• Each selected area explored until satisfied
• Scope creep redirected to deferred ideas
• CONTEXT.md captures decisions, not vague vision
• User knows next steps </success_criteria>
