treefmt SKILL.md skillA
treefmt 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/treefmt@git:20260406.3609531Pins git:20260406.3609531 in mdr.lock. Pin the fingerprint instead.

treefmt-nix and nix fmt guide. Unified formatting and linting with treefmt. Use when configuring or running nix fmt, treefmt, or adding formatters/linters to a Nix project.
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
# treefmt-nix
## 概要
[treefmt](https://github.com/numtide/treefmt)はプロジェクト内の複数言語ファイルを一コマンドで並列フォーマットするツールです。
[treefmt-nix](https://github.com/numtide/treefmt-nix)はNixモジュールシステムでtreefmtを設定・管理するラッパーです。
`nix fmt`コマンドはflakeの`formatter`出力を呼び出します。
treefmt-nixを組み込むと`nix fmt`の実体がtreefmtになり、
設定されたすべてのプログラムが実行されます。
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。
## フォーマッタだけではなくリンターも含む
`nix fmt`や`treefmt`という名前から「フォーマッタだけ」と誤解されがちですが、
treefmt-nixの`programs`にはリンターやチェッカーが多数含まれています。
フォーマッタの例:
- `nixfmt`
- `prettier`
- `rustfmt`
- `shfmt`
リンターの例:
- `actionlint`
- `deadnix`
- `hlint`
- `shellcheck`
- `statix`
その他:
- `typos`(スペルチェック)
- `zizmor`(GitHub Actionsセキュリティ)
treefmtのフォーマッタ仕様は「ファイルパスのリストを受け取り、変更があればファイルに書き戻す」というものです。
リンターはファイルを変更しませんが、エラー時に非ゼロ終了するためtreefmtがエラーとして検出します。
## 典型的な設定例
flake-partsを使う場合の例です。
```nix
{
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
flake-parts.url = "github:hercules-ci/flake-parts";
treefmt-nix = {
url = "github:numtide/treefmt-nix";
…Read the whole file at its exact version.
How to install
mdr add ncaq/konoka/treefmt@sha256:b903d156f807c24dThe line at the top of this page pins the label git:20260406.3609531, 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.
