description	Ask minimal clarifying questions only when ambiguity materially changes implementation. Use for routine underspecification; do not use for user-requested light or full grilling, plan stress-testing, or broad design interviews.

Ask Questions If Underspecified (OpenCode)

Use this skill when a request has multiple plausible implementations and picking the wrong one would cause rework, risk, or incorrect outcomes. This skill is intentionally narrow: it should unblock work with the fewest questions possible.

When to Use

• Key details are unclear: objective, done criteria, scope, constraints, environment, or safety
• Multiple reasonable interpretations would lead to materially different work
• You cannot resolve ambiguity with quick, read-only discovery

When NOT to Use

• The request is clear enough to proceed safely
• A quick repo read (files/config/docs) can answer the unknowns
• Repo conventions provide a safe default and ambiguity is low impact
• The user wants light or full grilling or plan stress-testing; use grill-questions or /grill instead

OpenCode-Specific Rules

1. Ask the minimum needed to unblock work (prefer one targeted question).
2. Use the question tool for user questions.
3. Put recommended/default choices first and tag them with (Recommended).
4. Do all non-blocked, low-risk discovery first.
5. Until must-have answers arrive, do not edit files or run state-changing commands.
6. If the user asks to proceed without answers, state assumptions briefly and continue with safest defaults.
7. Never turn this into a multi-turn design interview unless the user explicitly invokes /grill or asks to be grilled.

Workflow

1. Run quick discovery (read-only) to remove guesswork.
2. Identify only must-have unknowns that change implementation direction.
3. Ask 1-3 concise questions max in the first pass.
4. Prefer multiple-choice options over open-ended prompts.
5. Include a low-friction fallback, e.g. Use recommended defaults.
6. After answers, restate requirements in 1-3 sentences and proceed.

Must-Have Clarification Areas

• Objective: what should change and what should stay the same
• Definition of done: acceptance criteria, examples, edge cases
• Scope: what is in/out
• Constraints: compatibility, performance, style, dependency limits
• Environment: runtime/tooling versions when relevant
• Safety: migration, rollback, irreversible actions

Anti-Patterns

• Asking questions answerable via quick discovery
• Asking broad/open questions when options would be clearer
• Running a light or full grilling session under this skill instead of /grill
• Asking permission for routine safe steps
• Blocking on nice-to-know details that can use project defaults
• Asking users to reply with numbered text when the question tool can capture choices
