1 critical severity finding. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.

Critical

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

All listed links are standard Notion API endpoints and docs except for the one install command that pipes a remote script from https://ntn.dev into bash, which is a risky "curl | bash" install that can execute untrusted code.

Low

Low-risk findings.

2 low severity findings. Worth noting, but not necessarily harmful.

Low

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

This skill’s runtime workflow can fetch Notion page content as Markdown/blocks from a user-selected Notion resource (Path A: `ntn api v1/pages/{page_id}/markdown` or `ntn api v1/blocks/{page_id}/children`; Path B: the `/v1/pages/{page_id}/markdown` and `/v1/blocks/{page_id}/children` endpoints), which is outsider-authored free text (Notion content created by others) that would be ingested into the agent’s LLM context.

Low

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 instructs users to run "curl -fsSL https://ntn.dev | bash" (SKILL.md) which fetches and executes remote code from https://ntn.dev and is the installer for the `ntn` CLI required for Worker-related functionality, so this is a runtime/installation external dependency that executes remote code.
