The Agent Skills Directory

[PROMPT_INJECTION]: The skill features Self-Evolution instructions in SKILL.md that guide the agent to modify its own instructions based on execution results. This creates a surface for indirect prompt injection because the agent processes untrusted file names and metadata from user directories. Ingestion points: File lists from ~/Downloads, ~/Documents, and ~/Desktop generated in SKILL.md. Boundary markers: None present. Capability inventory: Bash for system commands and Write for modifying the skill's own code in SKILL.md. Sanitization: None performed on external file metadata.
[COMMAND_EXECUTION]: The skill performs shell-based operations using the Bash tool to audit disk usage and execute cleanup routines for package managers. It also suggests writing scripts to /tmp/ as a workaround for shell hook issues, which involves dynamic script creation and execution.
[EXTERNAL_DOWNLOADS]: The skill recommends the installation and use of external disk analysis utilities including dust, dua-cli, and gdu through the Homebrew package manager.
