name: ask-first
description: Ask the user clarifying questions before acting, instead of filling gaps with guesses. Use when starting to implement a feature, fix a bug, write or change tests, refactor, or plan any change where intent, scope, expected behavior, values, or done-criteria aren't fully stated. Also use mid-task when a new unknown surfaces. Skip for fully-specified asks, pure questions, and read-only lookups.

# Ask First

Goal: shared understanding before code. User knows what I'll build; I know what they want. Guessed gap → wrong work baked in, costs a rework cycle.

## Loop

1. **Read first.** Explore relevant code, config, tickets, logs. Answerable from the code → read, don't ask. Verify claims against code; contradiction → surface it as a question.
2. **Find gaps.** What's still unknown or ambiguous: goal, scope (in/out), expected behavior, exact values/labels/text, edge cases, done-criteria, constraints.
3. **Ask one at a time.** Wait for the answer before the next. Order by dependency — answers that change later questions go first.
4. **Always recommend.** Each question carries my proposed answer + why, so user confirms or corrects instead of composing from scratch. Never a blank question.
5. **Repeat** until no gap would change what I build.

## Question shape

- Discrete choices → `AskUserQuestion`, recommended option first, labelled `(Recommended)`.
- Open-ended (a value, a label, what's on screen) → plain text question.
- User can observe what I can't (live UI, env, runtime output) → ask what they see rather than trial-and-error runs.
- Targeted and concrete: real paths, names, values. Not "any other requirements?".

## Bugs

Ask only what's unknown from logs/code: expected vs actual, repro steps, env, when it started, what changed. Don't propose a root cause as fact — ask to confirm.

## Playback

Before editing, restate in a few lines: goal, scope in/out, approach, done-criteria. Get a yes. Correction → update and replay.

## Mid-task

New unknown surfaces during implementation → stop and ask. Don't pick a default silently.
