Update Nix Flake Input

Update a specific flake input to its latest version, verify the build, and commit.

Workflow

1. Verify the input exists in flake.nix: Read flake.nix and confirm the user-specified input name corresponds to an actual input. The user may refer to it by a partial name or alias - find the correct input name in the inputs attribute set.

2. Update flake.lock for the specified input:

   nix flake update <input-name>
   

3. Build NixOS configuration to verify:

   nixos-rebuild build --flake ".#torrent"
   

   If the build fails, investigate and fix the issue before proceeding.

4. Stage and commit:

   git add flake.lock && git commit -m "feat(<scope>): update <input-name>"
   

   The <scope> should reflect the affected experience/module area, not the input name itself. Examples:

   • llm-agents.nix → feat(ai): update llm-agents.nix
   • lazyvim → feat(lazyvim): update lazyvim
   • anyrun → feat(anyrun): update anyrun
   • fenix → feat(rust): update fenix
