The **markdownlint‑rule‑search‑replace** package adds a custom markdownlint rule that scans markdown files for specified strings or regex patterns and either flags them or automatically replaces them (e.g., turning “... ” into “…”, “--” into “—”, or banning words like “wtf”). It’s aimed at developers, documentation teams, and CI/CD pipelines who want to enforce consistent formatting or clean up recurring markup issues directly within their markdownlint workflow.
