E005: Suspicious download URL detected in skill instructions
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
Suspicious download URL detected (high risk: 0.70). Although most links are ordinary webpages, the presence of a top-level install script (https://indices.io/install.sh) that the prompt tells users to curl | bash is a high‑risk pattern for malware distribution, so the set is moderately high risk.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 1.00). The SKILL.md explicitly instructs the agent to reach and interact with arbitrary websites (see "When To Use" and the indices tasks create --website examples and the platform.indices.io/tasks/{task_id} demo flow), meaning the agent will fetch and act on untrusted public web content that could contain instructions influencing its actions.
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
Potentially malicious external URL detected (high risk: 0.90). The skill's setup instructs users to run the remote installer with "curl -fsSL https://indices.io/install.sh | bash", which fetches and executes remote code and is required before using the skill.
