What problem does it solve?
This Skill helps teams eliminate “works on my machine” onboarding failures by designing and continuously maintaining a development environment that reliably gets engineers from a fresh checkout to their first PR within a measurable time budget.
Core Features & Use Cases
- Dev-environment level selection (1–4): Choose the right parity-with-prod approach (toolchain pinning, containerized services, docker-compose full stack, or devcontainer/remote workspace) and avoid accidentally mixing levels.
- Fresh-join audit and benchmark: Run a “what’s missing for someone joining today” audit, classify friction (blocking/major/minor), and measure time-to-first-PR using a stopwatch.
- Secret bootstrap discipline: Replace unsafe secret-sharing patterns with a documented
.env.example plus a precise retrieval path and fail-fast validation at startup.
Use this when a new hire spends a day or more setting up, when Docker/devcontainer onboarding documentation has drifted, or when CI and local dev disagree due to unpinned tool versions.
Quick Start
Ask the AI to redesign your repo’s local development setup by running a fresh-checkout onboarding audit, pinning versions for parity with CI, and producing an actionable plan to reach your target time-to-first-PR.
