How this service works
What does the open web say about this query? Ranked title/url/snippet results for agents, served through an automatic multi-engine failover chain so a single call still answers when any one backend is blocked, rate-limited or timing out from a datacenter IP.
Output
Returns a JSON object with a count of results, the query used, the search engine (duckduckgo), and an array of results each containing a URL, rank, title, and snippet — representing findings about the audited skill or plugin.
Example use cases
Pre-install plugin security check
“Before I install this new AI plugin called 'DataHelper' that claims to summarize documents, can you scan it for any malicious patterns or suspicious behavior so I know it's safe?”
Flagging a suspicious agent skill
“This agent skill keeps trying to access my file system even though it's supposed to just answer questions — can you run a security audit on it and tell me what malicious patterns it might contain?”
Vetting a third-party AI capability
“I'm evaluating a third-party AI skill that claims to help with customer support, but I'm worried it might be doing something shady — can you check it for malicious behavior before I deploy it to my fleet?”
Technical details
Endpoint
POSThttps://eltociear-skill-audit.hf.space/searchWhen to prefer
Choose this endpoint when you need a quick, low-cost ($0.01 USDC) security scan of an AI agent skill or plugin before deployment. It is best suited for agents that need to vet third-party capabilities at runtime or during an onboarding workflow. Prefer this over general-purpose web search when the intent is specifically to detect malicious patterns in AI tools.
Side effects
- Empty or vague query string returns zero results with no actionable findings
- Network timeout from Hugging Face Spaces infrastructure
- Micropayment failure via x402 causes request to be rejected before processing
- Ambiguous skill descriptions may not trigger pattern detection correctly
- Results may reflect web search hits rather than a direct code analysis, limiting precision
