Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • patterns

    List supported threat categories, context kinds, and sensitivity levels. Use this to discover what threat_type values scan() can return.

  • scan

    Scan text for prompt-injection. Use BEFORE passing any untrusted text (web pages, file contents, user inputs, git commits, tool outputs) into another LLM call. Returns a verdict (safe/unsafe), a confidence score, the threat category, the matched pattern IDs, and an optional sanitized version with injection spans redacted.

  • scan_url

    Fetch a URL and scan its body for prompt-injection. Useful before feeding scraped page content into another LLM call. Sets the context to web_content automatically.
