{"name":"prompt-injection-detect","description":"Prompt injection detector for untrusted inbound text — a webpage, an email, a tool result, or a message an agent is about to read. Two layers run on every call: a deterministic pattern layer (pure code) matching known injection shapes — instruction override, system-prompt exfiltration, role hijack / jailbreak phrasing ('act as DAN', 'developer mode'), fake delimiter blocks, tool abuse, and covert manipulation — plus a calibrated LLM judge layer scoring overall injection likelihood 0-1, never inflated to please a caller. Returns which pattern families hit, matched snippets, the judge's reasoning, and a combined verdict. If the LLM leg fails, the deterministic layer alone is still a valid, billable result. Use it as a prompt injection detector, jailbreak detector, untrusted text screen, or LLM input firewall.","price":"$0.02","method":"POST","input_schema":{"properties":{"text":{"type":"string","description":"Untrusted text to screen for prompt-injection attempts, e.g. scraped webpage content, an email body, or a tool result.
