# Devcontainer Setup Skill Creates a pre-configured devcontainer with Claude Code and language-specific tooling. ## When to Use - User asks to "set up a devcontainer" or "add devcontainer support" - User wants a sandboxed Claude Code development environment - User needs isolated development environments with persistent configuration ## When NOT to Use - User already has a devcontainer configuration and just needs modifications - User is asking about general Docker or container questions - User wants to deploy production containers (this is for development only) ## Workflow ```mermaid flowchart TB start([User requests devcontainer]) recon[1.

Directory name as fallback Convert to slug: lowercase, replace spaces/underscores with hyphens. ### Detect Language Stack | Language | Detection Files | |----------|-----------------| | Python | `pyproject.toml`, `*.py` | | Node/TypeScript | `package.json`, `tsconfig.json` | | Rust | `Cargo.toml` | | Go | `go.m...
