Use when: A prompt is broad, underspecified or producing generic output.

Install this skill

Cursor, Claude Code and Codex

  1. Create a folder named `prompt-refiner`.
  2. Save the skill content below as `SKILL.md` inside that folder.
  3. Place the folder in `.cursor/skills/` for Cursor or `.claude/skills/` for Claude Code (or the equivalent path for Codex).
  4. Describe the task normally. Your agent loads the skill when its description matches.

Use this in ChatGPT or Claude (no code)

  1. Copy or download SKILL.md from this page (or put it in a folder named prompt-refiner).
  2. Zip that folder so the archive contains prompt-refiner/SKILL.md.
  3. In ChatGPT (Business, Enterprise, Edu or Healthcare), upload the zip under workspace Skills. In Claude.ai, add a Skill from the zip where your plan supports Skills.
  4. Describe the task in plain language — the skill loads when its description matches.

# Prompt Refiner

Turn the request into a brief an agent can execute and verify.

## Method

1. State the intended outcome in one sentence.
2. Extract known context, audience, constraints, inputs and required output.
3. Identify only the unknowns that would materially change the result.
4. Resolve low-risk gaps with explicit assumptions. Ask at most three focused questions for material gaps.
5. Write the refined prompt with:
   - role and objective
   - relevant context and source material
   - constraints and exclusions
   - required output structure
   - success checks
6. Remove filler, duplicated instructions and invented facts.

## Output

Return:

- **Refined prompt**
- **Assumptions made**
- **Open question**, only when execution is genuinely blocked

Do not execute the refined prompt unless the user asks you to.
