A rule-based review separates instruction components and calls no remote model.
System Prompt Clarity Checker
Reviews a system prompt using fully local rules and lists gaps in scope, instruction priority, failure behavior, data boundaries, and output format. It calls no model and does not guarantee safe behavior.
What does this tool do?
Check purpose, authority, boundaries, conflicts, ambiguity, and output contract with transparent rules.
SYSTEM PROMPT CLARITY REPORT ✓ Purpose / task ✓ Role and authority ✓ Boundaries / prohibitions ✓ Output format ✓ Uncertainty behavior ✓ Instruction priority ✓ Sensitive-data boundary The score does not guarantee safe or correct model behavior. Test the actual model and adversarial inputs separately.
System Prompt Clarity Checker: method and usage
Reviews a system prompt using fully local rules and lists gaps in scope, instruction priority, failure behavior, data boundaries, and output format. It calls no model and does not guarantee safe behavior.
an instruction with an explicit goal, audience, context, constraints, and expected output format Confirm the shape first with a small example containing no personal data.
an editable prompt draft, coverage metrics, and explicit improvement actions
Practical steps
- Paste the complete system prompt.
- Run the rule-based clarity check and review findings.
- Update the prompt and test actual model behavior separately.
model testing with representative normal, missing-context, conflicting, sensitive-data, and prompt-injection cases
The tool calls no remote model and neither generates nor verifies model output.
Suitable use cases
- Pre-production prompt review
- Finding instruction conflicts
- Clarifying safety boundaries
