tessl review fix ./.claude/skills/url-dump/SKILL.mdW011: 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
The skill’s required runtime workflow fetches and extracts “Main Content” from user-supplied URLs (“Fetch the web page content” → “Main Content: [extracted body text]”), which is outsider-authored free text from public web pages and is then ingested into the agent’s LLM context for summarization/insight extraction.
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
This skill explicitly fetches and ingests user-supplied URLs at runtime (e.g., "https://example.com/path?query=value" as the representative example) and injects the fetched page content into the model context to generate summaries/insights, meaning external content can directly influence agent prompts and behavior.
