nix-fast-build SKILL.md skillA
nix-fast-build from ncaq/konoka is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ncaq/konoka/nix-fast-build@git:20260406.544214aPins git:20260406.544214a in mdr.lock. Pin the fingerprint instead.

nix-fast-build command reference. Parallel Nix evaluation and build tool using nix-eval-jobs. Use when running or configuring nix-fast-build.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# nix-fast-build [Mic92/nix-fast-build](https://github.com/Mic92/nix-fast-build)は [nix-eval-jobs](https://github.com/nix-community/nix-eval-jobs)と [nix-output-monitor](https://github.com/maralorn/nix-output-monitor)を組み合わせて、 Nix式の評価を並列実行するツールです。 checksがビルドされるため、 適切にflake.nixで設定されていればリント・ビルド・テストが全て実行されます。 `nix flake check`と比べて評価が並列化されるため高速です。 FlakeはGitで追跡されているファイルのみを対象とするため、 新規ファイルがある場合は事前に`git ls-files --others --exclude-standard -z | git add --intent-to-add --pathspec-from-file=- --pathspec-file-nul`を実行してください。 未追跡ファイルがなく空の入力でもエラーにはなりません。 ## 典型的な使い方 ### 手元のターミナルで実行する場合 ```bash nix-fast-build --option eval-cache false --no-link --skip-cached ``` nomによるリッチな出力が表示されます。 ### Claude CodeやCIなど非対話環境で実行する場合 ```bash nix-fast-build --option eval-cache false --no-link --skip-cached --no-nom ``` nomはターミナル制御シーケンスに依存するため、 非対話環境では`--no-nom`を追加してください。 ## IFDを使うプロジェクトでの注意 nix-fast-buildは`--systems`でビルド対象を絞っても、 評価は全アーキテクチャに対して行います。 IFD(Import From Derivation)は評価フェーズでderivationのビルドを要求するため、 ローカルでビルドできないアーキテクチャのIFDが走ってエラーになることがあります。 `nix flake check`はNix 2.16以降デフォルトで他システムの評価をスキップするためこの問題が出にくいですが、 nix-eval-jobsにはその仕組みがありません。 ### 回避策: Flake URLでシステムを限定する 評価対象を現在のシステムに限定することで回避できます。 ```bash …

How to install
mdr add ncaq/konoka/nix-fast-build@sha256:471e18575b04942dThe line at the top of this page pins the label git:20260406.544214a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
