This is an Obsidian plugin that extends the built-in `obsidian://` URI scheme with additional `x-callback-url` endpoints for automation. It provides a modular routing system with endpoints for notes (CRUD, append/prepend, search/replace, touch), files, folders, vault info, commands, search, Dataview queries, Omnisearch, tags, and note properties. The architecture is modular: each route is defined in its own file under `src/routes/`, with Zod schemas for parameter validation and handler functions that return standardized success/failure objects. The main entry point is `src/main.ts`, which registers URI handlers and manages plugin lifecycle. Incoming URIs are matched to routes, parameters are validated and transformed (e.g., resolving file paths, UIDs, periodic notes), and the handler executes the requested action, sending callbacks via `x-success`/`x-error` URLs. External dependencies include the Obsidian API, Zod, `obsidian-daily-notes-interface`, `obsidian-dataview`, and `filter-obj`. The plugin also relies on third-party plugins (Templater, Periodic Notes, Dataview, Omnisearch) for certain routes. The codebase is well-structured with TypeScript, esbuild bundling, Jest E2E tests using a custom callback server, and comprehensive documentation.
