Adding custom GraphQL queries and mutations using GraphQLSchemaFactory. Use this skill when the developer wants to add custom GraphQL endpoints, create custom queries or mutations, add business logic to the API layer, build custom resolvers, inject backend…

The universal createImplementation DI pattern and all injectable services. Use this skill when the developer is writing any Webiny extension and needs to understand dependency injection, constructor injection, how to access Logger/BuildParams/IdentityContext,…

Turn open design questions into a paste-ready prompt for Claude Design, log them with Q-IDs and copy the prompt to the clipboard. Use for "/design-ask", "ask the designer", "questions for design".

Pull a Claude Design project into a local, git-ignored design folder and keep a catalogue of what was pulled and implemented. Use for "/design-pull", "pull the design", "sync designs", or to mark a design file as implemented after committing UI code built…

Modifying AWS infrastructure using Pulumi handlers and declarative Infra components. Use this skill when the developer wants to customize AWS infrastructure, add Pulumi handlers, configure OpenSearch, VPC, resource tags, regions, custom domains, blue-green…

Webiny project layout, webiny.config.tsx anatomy, and extension registration. Use this skill when the developer asks about folder structure, where custom code goes, how to register extensions, what webiny.config.tsx does, or how the project is organized. Also…

Building forms with the FormModel system — field types, renderers, layout, validation, conditional rules, computed fields, and dynamic zones. Use this skill when the developer needs to define form fields with the builder API, choose renderers, build layouts…

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…

Use when building CLI commands in src/cli/. Command structure, DI registration, the Prompts and UI abstractions, cancel handling, and testing through createCliTestContainer. Invoke BEFORE writing any CLI code. References project-architecture for DI patterns.

Use when creating abstractions, implementations, features, repositories, use cases, or any DI-wired service. Defines mandatory file separation — abstractions, implementations, null objects, and features MUST each be in their own file. Invoke BEFORE writing…

Shared architecture across CLI and UI layers. DI patterns (createAbstraction, createFeature, Result, BaseError), file separation, feature structure, naming, scoping. Invoke BEFORE writing any feature code in any layer.

Restructure code while preserving behavior. Use for extraction, consolidation, ownership moves, or cleanup where verification must bracket the structural edits — and for any refactor split across several agents working in the same tree.

Prove existing work meets its acceptance conditions without expanding scope. Use for validation-only tasks, completion checks, focused gate runs, and last-mile proof.

Use when building the local API/server layer that serves the UI. Handles project CRUD, seed job orchestration, and proxies to Webiny CMS GraphQL. Uses DI patterns from project-architecture. Invoke BEFORE writing any server/API code.

End-of-session handoff — updates AGENTS.md, writes a session handoff file, and generates a copy/paste prompt for the next agent. Use when user says "handoff", "wrap up", "end session", "clear context", or wants to prepare context for the next conversation.

Use when user says "review and fix", "review until clean", "run reviewer and fix", "keep reviewing until good", or wants iterative subagent review with automatic fixes applied between rounds. Works on specs, code, docs — any reviewable artifact.

Use when writing or editing a @webiny/data-transfer preset file (selected at runtime by the wizard or --preset flag). Covers createTransferPreset, pipelineBuilderFactory.create, filter/use/hook composition, first-match-wins record dispatch, unmatched-record…

Use when writing or editing a @webiny/data-transfer config file (ddb.transfer.config.ts / os.transfer.config.ts / custom.transfer.config.ts). Covers createDdbConfig / createOsConfig signatures, credential shapes (fromAwsProfile vs literal), fromEnv /…

Use when writing or editing a @webiny/data-transfer config file (config.ts). Covers createConfig signature, credential shapes (fromAwsProfile vs literal), fromEnv / numberFromEnv helpers, loadEnv, source/target collision + trimming rules, tuning knobs.

Use when writing or editing a @webiny/data-transfer preset file (the one referenced by pipeline.preset in a config). Covers createTransferPreset, pipelineBuilderFactory.create, filter/use/hook composition, first-match-wins record dispatch, unmatched-record…

Step-by-step guide for adding a new tool or service to @webiny/stdlib.

How dependency injection works in @webiny/stdlib — abstractions, implementations, features, and container wiring.

Testing conventions for @webiny/stdlib — container setup, tmpdir patterns, browser environment directives.

Guided feature development for @webiny/stdlib using the DI abstraction → implementation → feature → index pattern. Use when adding a new tool, service, or feature to any slice (common, node, browser). Enforces TDD, file conventions, barrel exports, README…

Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.

Use when writing a new Webiny upgrade script for a specific version in the webiny-upgrades-v6 project.
