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.

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.
01
Processing boundary

Input is processed only in the active browser tab's memory and is not sent to a ByteQuant server.

02
Persistent storage

Input and output are not stored. The optional usage counter keeps only tool identity and count, never content.

03
Verification

Output comes from disclosed rules or browser APIs and needs independent review before high-impact use.

HOW TO USE IT

A result in three steps

  1. 01

    Paste the complete system prompt.

  2. 02

    Run the rule-based clarity check and review findings.

  3. 03

    Update the prompt and test actual model behavior separately.

GOOD USE CASES

When is this tool useful?

  • Pre-production prompt review
  • Finding instruction conflicts
  • Clarifying safety boundaries
Important limitation

Automated output is a preliminary assessment. Do not use it alone for legal, financial, medical, or security-critical decisions.
