Phase 1: Question Engineering Protocol

Step 1 — Mandatory Codebase Scan (Before Asking ANY Questions)

You MUST research the project BEFORE formulating questions. Follow this exact sequence:

1. Run list_dir on the project root — catalog all modules and directories.
2. Read package.json (or equivalent manifest) — identify stack, scripts, dependencies, test framework.
3. Use grep_search for patterns related to the user's request (e.g., existing API routes, database models, auth logic).
4. Read 3–5 relevant source files to understand existing architecture, naming conventions, and patterns.
5. Check .specs/.steering/ for prior decisions (if it exists) — avoid re-asking settled questions.

Step 2 — Ambiguity Detection Checklist

Before formulating questions, evaluate these dimensions against the user's request:

Dimension	Ask If...
Data Model	Entities, relationships, or schemas are not specified
Error Handling	Failure modes, retry logic, or fallback behavior are not defined
Authentication / Authorization	Access control requirements are unclear
Integration Points	External APIs, services, or databases are mentioned but not specified
Performance / Scale	Load expectations, caching, or pagination are ambiguous
UI/UX Behavior	User flows, states (loading/error/empty), or responsive behavior are not defined
Scope Boundaries	It's unclear what is explicitly IN vs. OUT of scope

Step 3 — Formulate 3–5 Sharp Questions

Rules:

• Each question MUST reference a specific finding from your codebase scan.
• Each question MUST have 2–4 concrete, opinionated options (not generic placeholders).
• Use the ask_question tool with is_multi_select: true where appropriate.

Anti-Patterns (BANNED Questions)

Never ask these — they are inferable from the codebase or are obvious:

• ❌ "What tech stack are you using?" → Read package.json
• ❌ "Do you want tests?" → Always yes
• ❌ "What database are you using?" → Check existing config
• ❌ "Should we follow best practices?" → Always yes
• ❌ "What's the project structure?" → Run list_dir
• ❌ "Do you want error handling?" → Always yes
