The Agent Skills Directory

[COMMAND_EXECUTION]: The skill uses shell scripts to interact with the local rbenv and ruby-build environment. This is the primary intended functionality of the skill.
[SAFE]: Input validation is properly implemented in scripts/install.sh. The script uses grep -Fxq to ensure the requested version string exactly matches a version in the known available list before proceeding with the installation. This effectively prevents shell command injection via the version argument.
[SAFE]: No remote downloads, external network requests, or access to sensitive user credentials or configuration files were detected. The skill relies entirely on pre-installed local tools like Homebrew and rbenv.
[SAFE]: The skill's ingestion of local command output (from rbenv install -l) is handled safely using text processing tools like awk and grep for parsing, with no risk of indirect prompt injection affecting agent logic.
