What problem does it solve? Adding Mercur blocks to the basic starter involves error-prone steps: inaccurate block docs, destructive CLI overwrites of middlewares.ts, missing migrations, and misplaced UI routes. This Skill provides a disciplined workflow to evaluate, install, and verify blocks without breaking the project. ## Core Features & Use Cases - Block Discovery and Evaluation: Search and view blocks via the Mercur CLI before installing, mapping impact to the api, admin, and vendor aliases. - Safe Installation Workflow: Decline CLI middleware overwrites, merge middleware manually with correct export names and import paths, and apply config, env vars, and migrations from block docs. - Post-Install Verification: Check file placement, medusa-config registration, db:generate/db:migrate needs, UI route locations, and startup errors with bun run dev. - Use Case: When adding a reviews block, use this Skill to view it first, install it, manually merge its middleware into src/api/middlewares.ts, generate migrations for its custom module, and verify the API starts cleanly. ## Quick Start Use the mercur-blocks skill to search for, install, and verify the reviews block in my Mercur basic starter.
