Prompt Quality Checker
This tool evaluates a prompt for goal clarity, context, audience, constraints, examples, and output format. It returns both a score and a practical improvement checklist.

QUICK ANSWER
What does this tool do?
Score goals, context, constraints, and output format with transparent rules. Prompt Quality Checker limitation: Rule-based review does not prove real model behavior; retest with representative cases.
- Input
- For Prompt Quality Checker, provide an instruction with an explicit goal, audience, context, constraints, and expected output format. The requested outcome is to score goals, context, constraints, and output format with transparent rules.
- Output
- When Prompt Quality Checker finishes, it returns an editable prompt draft, coverage metrics, and explicit improvement actions, organised around the goal to score goals, context, constraints, and output format with transparent rules.
- Method
- Prompt Quality Checker uses this disclosed method to score goals, context, constraints, and output format with transparent rules: a rule-based review separates instruction components and calls no remote model.
- Verification
- Before accepting a Prompt Quality Checker result, complete model testing with representative normal, missing-context, conflicting, sensitive-data, and prompt-injection cases; the evidence should support the goal to score goals, context, constraints, and output format with transparent rules.

APPLICATION AND DECISION GUIDE
✓ REVIEWEDUse Prompt Quality Checker with the right input, acceptance check, and next step
This tool evaluates a prompt for goal clarity, context, audience, constraints, examples, and output format. It returns both a score and a practical improvement checklist. The notes below help you do more than produce a result: they show how to test whether Prompt Quality Checker fits the task and when to stop before a weak output travels further.
Prompt Quality Checker uses this disclosed method to score goals, context, constraints, and output format with transparent rules: a rule-based review separates instruction components and calls no remote model. Goal, context, output contract, and conflicting constraints are inspected separately. The tool runs no language model and applies only visible rules.
For Prompt Quality Checker, provide an instruction with an explicit goal, audience, context, constraints, and expected output format. The requested outcome is to score goals, context, constraints, and output format with transparent rules. Confirm the shape first with a small example containing no personal data.
When Prompt Quality Checker finishes, it returns an editable prompt draft, coverage metrics, and explicit improvement actions, organised around the goal to score goals, context, constraints, and output format with transparent rules. — Before accepting a Prompt Quality Checker result, complete model testing with representative normal, missing-context, conflicting, sensitive-data, and prompt-injection cases; the evidence should support the goal to score goals, context, constraints, and output format with transparent rules.
Three practical use cases
Pre-flight checks for production prompts: local analysis with Prompt Quality Checker
Action: Start with a small synthetic fixture that represents this need. Expected input: For Prompt Quality Checker, provide an instruction with an explicit goal, audience, context, constraints, and expected output format. The requested outcome is to score goals, context, constraints, and output format with transparent rules..
Acceptance signal: The fixture should reproduce “Pre-flight checks for production prompts: local analysis with Prompt Quality Checker” without real personal data.
Shared team prompt standards: validating the Prompt Quality Checker output
Action: Keep that fixture unchanged and run the on-device method: Prompt Quality Checker uses this disclosed method to score goals, context, constraints, and output format with transparent rules: a rule-based review separates instruction components and calls no remote model.
Acceptance signal: Identical input should return the same result, with no network or file action assumed beyond the disclosed method.
Improving ambiguous instructions: checking the limits of Prompt Quality Checker
Action: Retain the output record before moving it into the target workflow: When Prompt Quality Checker finishes, it returns an editable prompt draft, coverage metrics, and explicit improvement actions, organised around the goal to score goals, context, constraints, and output format with transparent rules..
Acceptance signal: Acceptance requires Before accepting a Prompt Quality Checker result, complete model testing with representative normal, missing-context, conflicting, sensitive-data, and prompt-injection cases; the evidence should support the goal to score goals, context, constraints, and output format with transparent rules.; otherwise do not move the result forward.
Do not use the result for a decision beyond this boundary: Prompt Quality Checker limitation: Rule-based review does not prove real model behavior; retest with representative cases.
Move the result to another tool or live process only after Before accepting a Prompt Quality Checker result, complete model testing with representative normal, missing-context, conflicting, sensitive-data, and prompt-injection cases; the evidence should support the goal to score goals, context, constraints, and output format with transparent rules.. Keep this limit visible in the decision record: Prompt Quality Checker limitation: Rule-based review does not prove real model behavior; retest with representative cases.
Worked decision record
Check whether a team summarisation prompt states its goal, context, output format, boundaries, audience, and verification criteria before sending it to a model.
Start with only `Summarise this report`; then add synthetic report context, a five-bullet format, executive audience, a no-invention boundary, and a date check.
The second version passes more visible checks, each missing component receives a separate reason, and rerunning the same text returns the same deterministic result.
Do not assume a high score proves model accuracy; test the prompt on the target model with representative success, boundary, and adversarial examples.
