read
Reads URLs and PDFs by fetching source content, defaulting to concise summaries for plain read requests and clean Markdown when asked to convert, save, quote, cite, or feed downstream work. Use when users ask in any language to read, fetch, check, summarize, quote, cite, convert, or save a URL or PDF. Not for local text files already in the repo.

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
The r.jina.ai and defuddle.md entries are third‑party proxy endpoints that accept arbitrary target URLs (including PDFs) and can obscure, cache, or relay content—making them a privacy risk and a plausible vector to distribute or obscure malicious downloads; the remaining links (Feishu API, raw.githubusercontent.com, and the GitHub repo) are official/standard and lower risk.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
Yes—when `fetch.sh` runs with `--use-proxy`, the LLM context can include fetched outsider free text from public URLs via third-party readers (`curl https://defuddle.md/{url}` and `curl https://r.jina.ai/{url}`), which return page content used to form the assistant’s response.
