webiny-api-cms-content-models Creating Headless CMS content models via code using the ModelFactory pattern. Use this skill when the developer wants to create, modify, or understand content model definitions, define fields and validators, set up reference fields between models, configure field layouts (including nested layouts inside object or dynamicZone fields), pick the correct Admin UI renderer for a field type (textInput/textInputs, lexicalEditor/lexicalEditors, file/files, objectAccordionSingle/objectAccordionMultiple, etc.), or work with the ModelFactory builder API. Also covers field types (text, longText, number, boolean, datetime, asset, file, ref, object, richText, dynamicZone), list (array) fields via .list() and the singular-vs-plural renderer rule, the mandatory datetime subtype (dateOnly/timeOnly/withTimezone/withoutTimezone), validation (required, unique, email, pattern, minLength, maxLength, gte, predefinedValues), single-entry (singleton) models via .singleEntry(), model/field tags via .tags(), and field rules via .rules(
Adding custom HTTP routes to the API with <Api.Route> and HttpRouteHandler. Use this skill when the developer wants to expose a custom HTTP endpoint (GET, POST, PUT, etc.) on the API alongside the GraphQL handler, implement a route handler with full DI support, or register a custom HTTP route in webiny.config.tsx.
The hub skill for all API/backend architecture in Webiny. Covers architecture overview, Services vs UseCases, feature naming and organization, feature structure templates, DI decision tree, anti-patterns, createFeature, createAbstraction, container registration, domain errors, entity patterns, naming conventions, scoping rules, and code conventions. Use this skill for ANY backend API work — it references sub-skills for deep implementation details.
