Software Development Skills

Implement the MongoDB persistence layer for a hexagonal architecture TypeScript project. Use this skill whenever the user needs to create or modify a MongoDB repository implementation, MongoDB document type, or entity mapper for MongoDB. Trigger when the user says things like "create a MongoDB repo for Foo", "add a mapper for Bar", "I need to persist Baz to MongoDB", "write the document type for Foo", "create the MongoDB repository and mapper", "wire up Foo to MongoDB", or whenever the project uses MongoDB and the storage layer for an entity is missing or incomplete. Also trigger when the user modifies an entity and the MongoDB persistence files need to stay in sync, or when they reference MongoDB-specific repo/mapper/document files by name. For the generic repository interface and mapper pattern (DB-agnostic), use the persistence skill instead.

Use when writing or reviewing Observable code from the @efesto-cloud/observable package.

Create, update, or maintain TypeScript type unions, template literal types, runtime enums, and dict mappings in a monorepo core package. Use this skill whenever the user needs to express a finite set of string values (states, phases, categories, MIME types, formatted strings) or needs the runtime enum version, human-readable labels, or value-mapping dicts for those types. Trigger on: "add a type for X", "create an enum for Y", "add a dict/description for Z", "add a state/phase type", "I need a list of X values at runtime", "map X to labels", "add a template literal type", or when creating/editing an entity that needs a constrained string field.
