Prompt checker

Check a prompt for a missing role, output format, length or example, and for broken tags and variables. Runs in your browser; nothing is uploaded.

4 suggestions.

  • Suggestion: It does not say who the answer is for or what role the model should take.Add a line such as "You are a patient tutor" or "Write for busy managers".
  • Suggestion: It does not describe the shape of the answer.Say what you want back: a table, three bullets, JSON with given keys, or headings.
  • Suggestion: It sets no length or limit.Add a limit such as "under 150 words" or "at most five bullets".
  • Suggestion: It gives no example of a good answer or input.One short example of the output you want often helps more than more instructions.

What the checker looks for

  • A role or audience, such as "You are a patient tutor" or "for busy managers".
  • An output format, such as a table, bullets, headings or JSON.
  • A length or limit, such as "under 150 words" or "at most five bullets".
  • An example of the answer or input you have in mind.
  • Broken syntax: invalid {{variable}} names, half-written placeholders, variables that differ only in capitalization, and unclosed or stray tags.
  • Structure in long prompts, such as labelled sections or tags.

Example

"Summarize this article about {{topic}}." gets four suggestions. A stronger version: "You are an editor for a busy product team. Summarize this article about {{topic}} in at most five bullets, decisions first. For example: 'Decision: ship the beta in May.'"

Questions

Does every prompt need all of these parts?

No. The checks look for parts that usually improve an answer: who it is for, what shape it should take, how long it should be and an example. A quick question does not need them all, so suggestions are not errors.

What is the difference between a problem and a suggestion?

Problems break the prompt: an invalid {{variable}} name, a half-written placeholder such as {{topic without its closing braces, two variables that differ only in capitalization, or a tag that is opened but not closed, or closed but never opened. Suggestions point to parts that are missing.

How does the checker decide?

With simple word patterns, in your browser. It looks for phrases such as "you are", "bullets", "under 100 words" or "for example". It does not understand meaning, so read each finding before changing your prompt.

Is my prompt sent anywhere?

No. The checks run in your browser. Only "Save to my library" sends the prompt, and only after you sign in.
