Document business rules, technical patterns, and service interfaces discovered during analysis or implementation. Use when you find reusable patterns, external integrations, domain-specific rules, or API contracts. Always check existing documentation before creating new files. Handles deduplication and proper categorization.
API contract design conventions for FastAPI projects with Pydantic v2. Use during the design phase when planning new API endpoints, defining request/response contracts, designing pagination or filtering, standardizing error responses, or planning API versioning. Covers RESTful naming, HTTP method semantics, Pydantic v2 schema naming conventions (XxxCreate/XxxUpdate/XxxResponse), cursor-based pagination, standard error format, and OpenAPI documentation. Does NOT cover implementation details (use python-backend-expert) or system-level architecture (use system-architecture).
QA skill orchestrator for test strategy, Playwright/E2E, mobile testing, API contracts, LLM agent testing, debugging, observability, resilience, refactoring, and docs coverage; routes to 12 specialized QA skills.
Builds new API endpoints end-to-end. Use when adding routes, handlers/controllers, validation, service/action logic, response schemas/resources, and endpoint tests.
API contract testing, authentication flows, rate limit handling, and error scenario coverage for n8n integrations with external services. Use when testing n8n node integrations.
Produces comprehensive system architecture plans for features and products including component breakdown, data flow diagrams, system boundaries, API contracts, and scaling considerations. Use for "system design", "architecture planning", "feature design", or "technical specs".
Help apps and distribution channels integrate PCS Hub into their frontend. Use when user says "/hub-api-integration", "integrate PCS Hub", "embed PCS Hub swap", "PCS Hub integration guide", "how do I add PCS Hub to my wallet", "create a PCS Hub integration spec", or describes wanting to embed PCS Hub quote/swap functionality in an external UI.
Apply when designing or implementing HTTP endpoints exposed by a VTEX IO backend service. Covers route boundaries, handler structure, middleware composition, request validation, and response modeling for service.json routes. Use for webhook endpoints, partner integrations, callback APIs, or reviewing VTEX IO handlers that should expose explicit HTTP contracts.
Design complete API contracts in OpenAPI 3.0/3.1 YAML with endpoints, schemas, security, pagination, error handling, and RFC 7807 problem details. Use when asking to design an API, create an OpenAPI spec, define API endpoints, write API contracts, or generate a Swagger specification.
Resilience review and testing: evaluate error handling, graceful degradation, API contract compliance, edge cases, and failure recovery with browser-based fault injection and validation.
Write a service catalog entry for a microservice or internal platform service — covering service identity, purpose, architecture context, SLAs, API contract summary, data classification, dependencies, operational runbooks, and known limitations. Use when asked to document a service for an internal developer portal, write a service README for a platform catalog, create a service overview page, or onboard a new service to a service registry. Produces a complete service catalog entry suitable for an internal developer portal or wiki.
Generate ABP Application.Contracts layer scaffolding (interfaces, DTOs, permissions) from technical design. Enables parallel development by abp-developer and qa-engineer. Use when: (1) backend-architect needs to generate contracts, (2) preparing for parallel implementation workflow, (3) creating API contracts before implementation.
