Prompt structure checklist

Client

A fast, offline checklist for common prompt sections. Use it with the token estimate and paste redact when polishing drafts.

Pattern-based scaffolding

Large prompts often mix a role, a clear task, an output shape, constraints, and sometimes examples. This page highlights which of those cues appear in your text so you can iterate before you spend tokens in a live session.

Prompt draft

?

This scans for common sections (role, task, format, guardrails, examples). It does not call any language model—only pattern matches. A sparse checklist does not mean your prompt is bad.

Structure checklist

5/5 cues detected

  • Role or personaWho the model should act as (e.g. “You are…”, “Act as…”, “Role:”, 你是…).
  • Task or objectiveWhat to accomplish (task, objective, instructions, 目标, 任务).
  • Output shapeExpected format (JSON, Markdown, bullets, “output format”, 输出格式).
  • Constraints or guardrailsBoundaries (don’t, must not, never, constraints, 不要, 禁止).
  • Examples or samplesFew-shot or illustration (example, e.g., 示例).

Common use cases

  • Sanity-check a draft before pasting into a chat or agent—especially when reliability beats creativity.
  • Onboard teammates with a shared mental model of what “complete” prompt scaffolding often includes.
  • Pair with token estimate and paste redact when preparing long or sensitive context blocks.

Common mistakes to avoid

  • Treating misses as failures

    Short or highly domain-specific prompts can work with few checklist hits. Use this as a nudge, not a grade.

  • Expecting semantic rewriting

    This tool never calls a generative model. It only searches for common section cues in plain text.

FAQ

Does my prompt leave the browser?

No. All checks run locally with JavaScript string patterns.

Will this catch missing safety rules?

Only if you express them with typical words (constraints, don’t, must not). It is not a security or policy auditor.
