# ask-questions-if-underspecified

The skill makes the agent ask 1–5 clarifying questions before it starts work, so you don't get the wrong thing built. Invoked manually.

## What it does

This skill kicks in when a request is vague. The agent checks six things: the objective, what counts as done, scope, constraints, environment, and how reversible the change is. If several readings of the task are plausible, it treats the request as underspecified.

Then comes a short round of questions. They're numbered, answers are lettered, so you can reply with something compact like `1b 2a 3c`. The recommended option is marked as the default, and there's a fast path: reply `defaults` to accept them all. Until answers arrive, the agent won't edit files or run commands. Only a low-risk look around is allowed, such as reading repo structure or config files.

Ask it to proceed anyway and the skill wants your assumptions written out as a numbered list first, with confirmation before any work. It also rules out two habits: asking things a quick config or docs read would answer, and asking open-ended questions where a multiple-choice would settle it faster. Nothing here fires on its own, so in day-to-day use the skill stays quiet until you call it.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill ask-questions-if-underspecified -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ask-questions-if-underspecified/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ask-questions-if-underspecified/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill ask-questions-if-underspecified -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ask-questions-if-underspecified/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill ask-questions-if-underspecified -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ask-questions-if-underspecified/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MoizIbnYousaf/ai-agent-skills ask-questions-if-underspecified
```

2. **Manually: put the files in place**
- File: `.github/skills/ask-questions-if-underspecified/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill ask-questions-if-underspecified -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MoizIbnYousaf/ai-agent-skills --path skills/ask-questions-if-underspecified
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ask-questions-if-underspecified/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MoizIbnYousaf/ai-agent-skills --skill ask-questions-if-underspecified -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/MoizIbnYousaf/ai-agent-skills/tree/HEAD/skills/ask-questions-if-underspecified/SKILL.md

## When to use it
- pin down acceptance criteria before the agent writes code
- split one vague request into distinct interpretations
- set scope: which files are in and which stay untouched
- surface runtime and build environment targets
- talk through data migration risk and rollback

## Example prompts
- Use the ask-questions-if-underspecified skill on my request to add caching to the API, then wait for my answers
- ask-questions-if-underspecified: what do you need to know before refactoring the payments module?
- Run ask-questions-if-underspecified on my schema migration task and hold off until I reply

# Ask Questions If Underspecified

## Goal

Ask the minimum set of clarifying questions needed to avoid wrong work; do not start implementing until the must-have questions are answered (or the user explicitly approves proceeding with stated assumptions).

## Workflow

### 1) Decide whether the request is underspecified

Treat a request as underspecified if after exploring how to perform the work, some or all of the following are not clear:
- Define the objective (what should change vs stay the same)
- Define "done" (acceptance criteria, examples, edge cases)
- Define scope (which files/components/users are in/out)
- Define constraints (compatibility, performance, style, deps, time)
- Identify environment (language/runtime versions, OS, build/test runner)
- Clarify safety/reversibility (data migration, rollout/rollback, risk)

If multiple plausible interpretations exist, assume it is underspecified.

### 2) Ask must-have questions first (keep it small)

Ask 1-5 questions in the first pass. Prefer questions that eliminate whole branches of work.

Make questions easy to answer:
- Optimize for scannability (short, numbered questions; avoid paragraphs)
- Offer multiple-choice options when possible
- Suggest reasonable defaults when appropriate (mark them clearly as the default/recommended choice; bold the recommended choice in the list, or if you present options in a code block, put a bold "Recommended" line immediately above the block and also tag defaults inside the block)
- Include a fast-path response (e.g., reply `defaults` to accept all recommended/default choices)
- Include a low-friction "not sure" option when helpful (e.g., "Not sure - use default")
- Separate "Need to know" from "Nice to know" if that reduces friction
- Structure options so the user can respond with compact decisions (e.g., `1b 2a 3c`); restate the chosen options in plain language to confirm

### 3) Pause before acting

Until must-have answers arrive:
- Do not run commands, edit files, or produce a detailed plan that depends on unknowns
