open

The skill implements a legitimate integration (open files in Emacs) but relies on evaluating Elisp in the user's Emacs process and loading a local helper file — both are high-impact sinks. The main risks are local code execution (if the helper is tampered with or the eval payload is manipulated), unrestricted read access to arbitrary absolute paths (possible exposure of sensitive data), and lack of per-action confirmation. No explicit remote exfiltration is present in the provided code alone, but arbitrary Elisp could perform network I/O if the helper or payload is malicious. Recommend integrity checks for agent-skill-open.el, path restrictions and prompts, careful quoting of eval payloads, and limiting file-open scope to minimize supply-chain and data-exposure risk.
