The Agent Skills Directory

[COMMAND_EXECUTION]: The skill uses sudo -n to perform high-privilege system operations, including nix-collect-garbage, docker system prune, and podman system prune. It also executes ncdu as root to profile the entire filesystem.
[PROMPT_INJECTION]: The skill implements a self-modification mechanism in the "Learning Loop" section, instructing the agent to update its own instruction files (SKILL.md and references/ignore-paths.md) based on discovered system data.
Ingestion points: File system paths, mountpoints, and command patterns discovered during runtime via findmnt, du, and ncdu.
Boundary markers: Absent. Discovered strings are incorporated directly into markdown instruction files without delimiting markers or warnings.
Capability inventory: High-privilege command execution via sudo and the ability to download and execute external tools via nix run.
Sanitization: Absent. No validation or escaping is performed on discovered file paths before they are written to the skill files.
[EXTERNAL_DOWNLOADS]: The skill fetches and executes utility packages (such as cargo-sweep and ncdu) from the official Nixpkgs registry using the nix run command.
