skillz

The server exposes a `fetch_resource` tool that allows clients to retrieve files associated with skills. It includes explicit and robust path traversal checks (`'..' in rel_path_str` and `rel_path_str.startswith('/')`) to prevent unauthorized file access outside of skill directories. Content is correctly handled, either decoded as UTF-8 text or base64-encoded for binary data. No `eval` or code obfuscation patterns were identified. The primary risk would stem from malicious content within the loaded skill files themselves, which the server serves; however, the server's role is primarily to deliver this content securely.
