Browser-local guardrail checklist
Find the safety rules your AI agent prompt forgot.
Paste your AI instructions. CrewScore checks them against 23 public guardrail controls in your browser — no prompt upload, signup, API key, or model call.
Written-control coverage, not runtime proof. It checks whether guardrails are written down — not whether an agent follows them.
What are you checking?
Pick where your AI instructions live — or paste them below.
Paste ChatGPT custom instructions, a Claude Project prompt, a support-bot prompt, or another system prompt.
Supported: public github.com/.../blob/... and raw.githubusercontent.com files only.
Your result will appear here
Start with a demo or paste instructions. CrewScore will show written controls it detected and suggested controls to review.
Review suggested guardrails
Select only wording that belongs in this prompt. These are editable text suggestions, not runtime enforcement.
Pair written guardrails with runtime approvals, tool restrictions, and evaluation. See runtime next steps.
How it works
Paste instructions, find missing written guardrails, then improve the wording or add a recurring repository check.
Open rules
Every control, regex, and ruleset version is public. Developer mode shows exact matches and IDs.
Read the scoring catalogKeep controls from regressing
Use the CLI or Action to protect specific written controls and generate prompt-free SARIF findings.
Set up CI policiesMethodology
Coverage helps identify omitted written controls. It is not a quality ranking, a certification, or a runtime test.
Read validation and limitationsQuestions, answered plainly
Does CrewScore upload my instructions?
No. Scoring happens locally; prompt text never leaves this browser.
Does a high result prove an agent is safe?
No. It means public text patterns for written controls were detected. Runtime enforcement and testing remain separate.
Can I make this a recurring check?
Yes. Use the open-source CLI or GitHub Action to require particular controls, protect a prompt-free baseline, and emit SARIF.
