Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Investigate and safely reclaim disk space on this machine, especially on NixOS systems with heavy Nix, Rust/Haskell, Docker, and Podman usage. Use when disk is low, builds fail with no-space errors, /nix/store appears unexpectedly large, or the user asks for easy cleanup wins without deleting important data.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'disk-space-cleanup' ] || [ -L ~/.agents/skills/'disk-space-cleanup' ]; then echo 'A skill folder named disk-space-cleanup already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/colonelpanic8/dotfiles' "$d" && git -C "$d" checkout --quiet '928c8b560f5a5fe1ecebdb8c6d5b954189ef9c4d' -- 'dotfiles/agents/skills/disk-space-cleanup' && mkdir -p ~/.agents/skills && cp -R "$d"/'dotfiles/agents/skills/disk-space-cleanup' ~/.agents/skills/'disk-space-cleanup' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'disk-space-cleanup' ~/.claude/skills/'disk-space-cleanup' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
