Flox Environments

skill

Floxで再現可能なクロスプラットフォーム開発環境を作成します — Nixに基づく宣言的な環境マネージャー。次の場合は必ずこのスキルを使用してください: システムレベルの依存関係（コンパイラー、データベース、openssl・libvips・BLAS・LAPACKなどのネイティブライブラリー）を持つプロジェクトを設定する場合; Python、Node.js、Rust、Go、C/C++、Java、Ruby、Elixir、PHP、その他の言語の再現可能なツールチェーンを設定する場合; macOSとLinux間で同一に動作する環境を管理する場合; チームのために正確なパッケージバージョンを固定する場合; ローカルサービス（PostgreSQL、Redis、Kafka）を開発ツールと並行して実行する場合; 単一コマンドで新しい開発者をオンボードする場合; または「自分のマシンでは動く」問題を解決する場合。AI支援やバイブコーディングに特に価値があります — Floxはエージェントがsudoなし、システム汚染なし、サンドボックス制限なしにプロジェクトスコープの環境にツールをインストールでき、結果の環境はリポジトリにコミットされるため、誰でも即座に再現できます。ユーザーがFloxに言及しない場合でも、再現可能、宣言的、クロスプラットフォームな開発環境とシステムパッケージが必要と説明した場合はこのスキルを使用してください。また、ユーザーが.flox/、manifest.toml、flox activate、またはFloxHubに言及した場合も使用してください。

Security audit

Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.

Its own instructions

Its SKILL.md shows worked examples and covers setup.

Read from the capability’s own SKILL.md. This is not a grade and does not compare to the instruction-depth verdict on an MCP server — a skill has no tools to document, so that rubric does not apply to it.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.

tashan Pro$6/mo

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.

Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
