pinning-reproducible-environments

What problem does it solve?

This Skill removes environment drift by pinning dependencies, runtimes, and base images so the same project behaves consistently on a laptop, in CI, and months later.

Core Features & Use Cases

• Dependency locking across ecosystems: Supports Python with uv, poetry, or pip-tools; Node with npm or pnpm; and R with renv.
• Runtime and image pinning: Requires exact language runtime versions and digest-pinned Docker or devcontainer base images.
• Reproducibility workflows: Fits new project setup, CI mismatches, teammate onboarding, paper and audit requirements, and weekly drift checks that detect stale locks.
• Guardrails and anti-pattern detection: Distinguishes real projects from throwaway notebooks and flags floating tags, missing lockfiles, and non-strict installs.

Quick Start

Ask the Skill to set up reproducible dependencies for your project, then have it pin the lockfile, runtime version, and CI drift-check workflow for the ecosystem you are using.
