This skill upgrades NixOS to a new release version (e.g., 25.05 → 25.11). Triggers: "upgrade nixos", "upgrade to new release", "update nixos version", "move to nixos 25.11", "nixos release upgrade", "upgrade system version". Researches breaking changes, updates flake inputs, guides through upgrade. Not for flake.lock updates within same release (use upgrade-flake for that).

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/'upgrade-nixos' ] || [ -L ~/.agents/skills/'upgrade-nixos' ]; then echo 'A skill folder named upgrade-nixos already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/richardgill/nix' "$d" && git -C "$d" checkout --quiet '74d2bde87aa222987928b9a2f4ac9a540ffd5e42' -- '.claude/skills/upgrade-nixos' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/upgrade-nixos' ~/.agents/skills/'upgrade-nixos' && 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/'upgrade-nixos' ~/.claude/skills/'upgrade-nixos' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
