What problem does it solve? Cloudflare Workers projects that depend on D1 often suffer from misconfigured bindings, unclear local-vs-remote database behavior, and implicit migration or seed workflows. This Skill inventories the D1 surface of a project and turns scattered configuration into a concrete development plan before deeper implementation work begins. ## Core Features & Use Cases - D1 Surface Inventory: Runs a helper script to locate Wrangler config files, d1_databases declarations, preview_database_id usage, migration and seed files, and D1-related code usage. - Binding and Workflow Validation: Verifies binding names, Wrangler scopes, local versus remote development mode, and migration/seed discipline, flagging drift between code, docs, and config. - Development Plan Output: Produces a structured Markdown plan covering the binding model, local and preview behavior, migration status, and recommended next steps. - Use Case: Before adding a new D1-backed feature to a Workers app, run the inspection to confirm the binding is declared correctly, migrations are reproducible locally, and preview database expectations are documented. ## Quick Start Ask the AI to inspect the D1 development setup in your Cloudflare Workers project and produce a development plan covering bindings, migrations, and local versus remote behavior.
