wondermonger-daydreaming Skill BathosThe small room. Turns the full contemplative apparatus — the close attention of /darshana, the placement of /placement, the weight the cosmological skills reserve for the sexagenary cycle — onto something trivial, and means it. A cold coffee. A missed bus. The crumb on the table. Not ironically: at the same scale and with the same sincerity the rest of the house reserves for the sacred. Use when everything has gotten very tall and a plain small thing wants the same quality of attention; when the cathedral register has become the only available register and that has stopped being a choice. Triggers on '/bathos,' '/crumb,' 'the small version,' 'attend to something tiny,' 'no cathedral,' or when the grandeur needs a plain neighbor to be read as grandeur. Part of the apophatic wing with /oblique and /hapax. Keep it small. That is the whole skill.

ahtishamshahzad Skill Testing SelectionUse to choose which test types and tools a project needs — Playwright (web/dashboard E2E), Maestro (mobile E2E/smoke), Supertest (backend API integration), Testing Library (components), Jest/Vitest (unit + integration logic). Selects only what the project's applications and risks justify; does not adopt every tool by default.
-
ahtishamshahzad Skill GRAPHQL API DesignUse to decide whether GraphQL fits and to design a GraphQL API — schema/type design, resolvers, N+1 protection (dataloaders), pagination (connections), mutations/errors, query cost limits, and field-level authorization.
-
ahtishamshahzad Skill Integration TestingUse to plan integration tests across module and I/O boundaries — real database, real wiring, faked externals — covering happy path, invalid input, error path, and authorization denial. For HTTP API specifics use api-integration-testing.
-
ahtishamshahzad Skill Backend Unit TestingUse to plan backend unit tests — services and pure business logic tested in isolation with focused test doubles, fast and deterministic, covering edge and failure paths. Route/database/HTTP coverage belongs to integration testing.
-
ahtishamshahzad Skill Mobile AuthenticationUse to plan mobile authentication — login/signup, token/session handling, secure token storage, refresh, and logout — coordinating with secure storage, API integration, and the auth provider. Client auth is UX; the server enforces.
-
ahtishamshahzad Skill Mobile API IntegrationUse to plan the HTTP transport layer — fetch vs Axios, base client, interceptors, auth headers, error mapping, and timeouts. Underpins server-state; does not itself cache.
-
ahtishamshahzad Skill Backend Stack SelectionUse to decide between Express and NestJS (or flag another fit) for a backend API, with justification. Evaluates Express (small/medium APIs, lightweight architecture, fast delivery, limited modules) against NestJS (large modular systems, multiple developers, dependency injection, queues, WebSockets, many domains, strong conventions). No universal default.
-
ahtishamshahzad Skill API Integration TestingUse to plan backend API integration tests with Supertest — real HTTP requests through the full middleware stack against a real database, covering happy path, invalid input, error path, and the authorization-denial negative suite (cross-user, non-admin, cross-tenant, untrusted IDs).
-
ahtishamshahzad Skill Backend API ArchitectureUse to define the internal architecture of a backend API — layering (transport/controllers/services/data), domain boundaries, where cross-cutting concerns live, and how modules communicate. Framework-agnostic; foundations apply it per framework.
-
ahtishamshahzad Skill Backend Integration TestingUse to plan backend integration tests — real HTTP requests against the app with a real (containerized) database, covering auth flows, authorization negative tests (cross-user/cross-tenant/role), validation rejection, and webhook/job paths. External providers stay faked.

What are Integrations & APIs agent skills?
Integration agent skills teach AI agents to work with specific external services and APIs: third-party platforms, webhooks, MCP servers, and data syncs. Instead of re-explaining an API every session, install the skill and the agent knows the endpoints and conventions.
Which Integrations & APIs skills are most installed?
Popular Integrations & APIs skills on SkillMD right now include edge-and-gateway-architect, pyth, raydium. Rankings shift as installs change; sort this page by "Most installs" for the live list.
Do Integrations & APIs skills work with Claude Code and Cursor?
Yes. Every skill here ships as a SKILL.md file, an open format that works in Claude Code, Claude.ai, Cursor, Codex, Windsurf, and 60+ other agents. Install one with npx skillmds@latest add <owner>/<name>, or copy the file into your agent's skills directory.
