External Package Sources

Packages missing from stable Nixpkgs are supplied by dedicated flake inputs and overlays.

Source	Role	Platforms and cache
llm-agents (github:numtide/llm-agents.nix)	Prebuilt AI-agent packages selected by llmAgentsPackages: apm, ccstatusline, claude-code, claude-desktop, grok-bot, orca, and paperclip.	Ships Linux and Apple Silicon builds; Intel macOS has no package set. Cached on cache.numtide.com.
nur-packages (github:NoSugarCoffee/nur-packages)	Project-maintained repacks and packages absent from or Linux-only in Nixpkgs, exposed under pkgs.nosugarcoffee.	Prebuilt for supported systems and cached on nosugarcoffee.cachix.org; Intel macOS falls back to the overlay against Nixpkgs 26.05.
nixpkgs-unstable	Newer selected packages, including macshot, code-cursor, codex, and chatgpt, overlaid into the otherwise stable package set.	Evaluated for each supported system with unfree packages enabled.

The external inputs intentionally do not follow the repository’s Nixpkgs pin: their own package revisions must match their caches. nix flake update refreshes the lock file; no package derivations belong in this repository.
