Wire up DevContainers / GitHub Codespaces — `devcontainer.json`, container images, secrets, VS Code features, port forwarding. NOT for tuning Copilot itself (use `copilot-config`).
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
# devcontainer ## When to use Use this skill when working with DevContainer configuration, GitHub Codespaces setup, or development environment standardization. Do NOT use when: - Local Docker setup without Codespaces (use `docker` skill) - Production deployment (use `aws-infrastructure` skill) ## Procedure: Modify DevContainer 1. **Gather context** — read `.devcontainer/devcontainer.json`, check `.devcontainer/` for env files and docs, check `agents/overrides/skills/devcontainer.md` for project-specific overrides. 2. **Identify change type** — classify: image change, feature addition, secret addition, extension change, or env var change. 3. **Make the change** — edit `devcontainer.json` (or related files). Follow conventions below for secrets, features, and environment variables. 4. **Build and verify** — run `devcontainer build` to confirm the container builds. Check that extensions load and ports forward correctly. 5. **Document** — if adding a new secret or dependency, update the onboarding docs in `.devcontainer/`. ## Architecture ### Custom image …

How to install
mdr add event4u-app/agent-config/devcontainer@sha256:24b3aa7517695a17The line at the top of this page pins the label git:20260603.668ed88, 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.
