devcontainer-setup
Creates devcontainers with Claude Code, language-specific tooling (Python/Node/Rust/Go), and persistent volumes. Use when adding devcontainer support to a project, setting up isolated development environments, or configuring sandboxed Claude Code workspaces.
npx skills add trailofbits/skills --skill devcontainer-setup --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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. Project Reconnaissance] detect[2. Detect Languages] generate[3. Generate Configuration] write[4. Write files to .devcontainer/] done([Done]) start --> recon recon --> detect detect --> generate generate --> write write --> done ``` ## Phase 1: Project Reconnaissance ### Infer Project Name Check in order (use first match): 1. `package.json` → `name` field 2. `pyproject.toml` → `project.name` 3. `Cargo.toml` → `package.name` 4. `go.mod` → module path (last segment after `/`) 5. Directory name as fallback Convert to slug: lowercase, replace spaces/

What does the devcontainer-setup skill do?
Creates devcontainers with Claude Code, language-specific tooling (Python/Node/Rust/Go), and persistent volumes. Use when adding devcontainer support to a project, setting up isolated development environments, or configuring sandboxed Claude Code workspaces.
How do I install it?
Run `npx skills add trailofbits/skills --skill devcontainer-setup --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From trailofbits/skills, a repository with 6,426 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
