<arguments>$ARGUMENTS</arguments>

The text inside `<arguments>` is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.

<objective> Clarify phase requirements through structured Socratic questioning with quantitative ambiguity scoring.

**Position in workflow:** `spec-phase → discuss-phase → plan-phase → execute-phase → verify`

**How it works:** 1. Load phase context (PROJECT.md, REQUIREMENTS.md, ROADMAP.md, STATE.md) 2. Scout the codebase — understand current state before asking questions 3. Run Socratic interview loop (up to 6 rounds, rotating perspectives) 4. Score ambiguity across 4 weighted dimensions after each round 5. Gate: ambiguity ≤ 0.20 AND all dimensions meet minimums → write SPEC.md 6. Commit SPEC.md — discuss-phase picks it up automatically on next run

**Output:** `{phase_dir}/{padded_phase}-SPEC.md` — falsifiable requirements that lock "what/why" before discuss-phase handles "how" </objective>

<runtime_note> **Copilot (VS Code):** Use `vscode_askquestions` wherever this workflow calls `AskUserQuestion`. They are equivalent. </runtime_note>

<context> Phase number: the `<arguments>` block (required)

**Flags:**

• `--auto` — Skip interactive questions; Claude selects recommended defaults and writes SPEC.md
• `--text` — Use plain-text numbered lists instead of TUI menus (required for `/rc` remote sessions)

Context files are resolved in-workflow using `init phase-op`. </context>

<process> Execute end-to-end.

**MANDATORY:** Read the workflow file BEFORE taking any action. The workflow contains the complete step-by-step process including the Socratic interview loop, ambiguity scoring gate, and SPEC.md generation. Do not improvise from the objective summary above. </process>

<success_criteria>

• Codebase scouted for current state before questioning begins
• All 4 ambiguity dimensions scored after each interview round
• Gate passed: ambiguity ≤ 0.20 AND all dimension minimums met
• SPEC.md written with falsifiable requirements, explicit boundaries, and acceptance criteria
• SPEC.md committed atomically
• User knows they can now run /gsd:discuss-phase which will load SPEC.md automatically
