Prompt Injection Scanner for fast browser-based work
Scan web text, retrieved snippets, and third-party prompts for common prompt injection and instruction override patterns.
中文：检查网页文本、检索片段和第三方 prompt 中常见的 prompt injection 与指令覆盖风险。
Example: Paste website copy, RAG context, README snippets, or a shared prompt before feeding it to an AI agent.
Where this tool fits in real work
Use cases
- Scan website copy, retrieved snippets, README text, or shared prompts before putting them into an AI agent workflow.
- Spot attempts to ignore previous instructions, reveal system prompts, request secrets, hide behavior, or trigger tool actions.
- Wrap untrusted content in a defensive prompt that separates data from instructions.
Review notes
- A clean result is not a safety guarantee; prompt injection can be subtle and context-specific.
- Treat web pages, emails, repository text, and user-generated content as untrusted data by default.
- Do not let external text grant tool permissions, change the agent role, or override user intent.

Use a stricter workflow
If the context includes production secrets, customer records, private research material, or executable scripts, redact first and use a stricter human review workflow.

Prompt Injection Scanner questions
Does this prove content is safe?
No. It identifies suspicious instruction patterns and provides a defensive wrapper prompt.
Does it call a model?
No. It uses local pattern checks in your browser.
Is this tool free?
Yes. The current Toolkits tools are free to use and do not require an account. If advertising is added later, it should be clearly labeled and kept away from primary tool controls.
