The Agent Skills Directory

[DATA_EXFILTRATION]: The skill accesses and reads sensitive application configuration and cache files located in the ~/.claude/ directory, including settings.json and plugin metadata. While this is aligned with the skill's stated purpose, it exposes user settings and plugin internals to the agent context.
[COMMAND_EXECUTION]: The skill performs bulk file system operations using find, chmod, sed, and rm to modify plugin scripts and cache metadata. It specifically targets executable permissions and script content, including patterns that suppress script errors (2>/dev/null || true), which can reduce the auditability of the plugin system.
[REMOTE_CODE_EXECUTION]: The Phase 4 verification logic extracts command strings from hooks.json files and executes them using eval. This constitutes dynamic execution of commands defined in external configuration files, which could lead to arbitrary code execution if a plugin's cache or manifest has been compromised.
