contextlint-init

Bootstrap contextlint into a repository. Use this skill whenever the user wants to set up, install, initialize, or configure contextlint — even if they only say "lint setup", "doc integrity check", or "set up Markdown linting" without naming contextlint by name. Detects the package manager (bun/npm/pnpm/yarn), scans the repo's actual doc layout (no hardcoded docs/ assumption), infers a rule set tailored to the project's structure (ADR style, spec style, table-heavy, etc.), installs @contextlint/cli, and writes contextlint.config.json. Also handles existing contextlint setups and offers optional GitHub Actions workflow + README scaffolding.
