What problem does it solve? Repositories adopting the ee-standard control register need the register-check executable present before any gate, pre-commit hook, or CI job can run it, but nothing else in the plugin installs it. This Skill adds register-check as a pinned git dependency so every locus that invokes the checker has something to run. ## Core Features & Use Cases - Register-driven pinning: Composes the dependency requirement entirely from the register's tools.register-check.install address and the ecosystem's git_dependency grammar, never hardcoding a URL or tag. - Ecosystem detection from files: Determines the package ecosystem by inspecting manifests and lockfiles (pyproject.toml, uv.lock, package.json, go.mod) rather than asking the user. - Safe, confirmed installs: Shows a plan and asks for confirmation before writing, handles new installs, no-op re-runs, and upgrades distinctly, and verifies via the package manager runner plus lockfile inspection. - Use Case: While adopting the control register into a Python repository, run this Skill so the pre-commit hooks and CI job that call register-check resolve against a pinned, locked version. ## Quick Start Ask the assistant to install the register-check checker into this repository using the register-install skill, pinned to the ref named in controls.yaml.
