Integrations & APIs

blakeox Skill

Consumer-compatibility and contract-validation specialist. Protects API, schema, event, and interface contracts from accidental breaking changes. Use for public APIs, SDK-backed endpoints, shared schemas.

bybren-llc Bundle

API route implementation patterns with RLS, Zod validation, and error handling. Use when creating API routes, implementing endpoints, or adding server-side validation.

futuregerald Bundle

Structure Go API and service codebases — package layout, interface-driven dependency direction, and the HTTP edge. Use when starting a Go service, adding a feature or endpoint, deciding which package a file or type belongs in, resolving an import cycle, reviewing Go layout in a PR, or asking "how should I structure my Go project". Also before writing Go that touches a database, HTTP client, cache, queue, or clock, so it lands behind a consumer-declared interface. Covers routing, handlers, middleware placement and order, panic recovery, decoding and validating a JSON body, rejecting oversized input, where wire DTOs live, structured logging with slog, liveness versus readiness health checks; context deadlines, cancellation, ctx-first, WithValue keys; config loading; testing — where tests belong, functional tests, fakes, synctest, race and goroutine-leak detection; and concurrency — worker pools, job queues, bounding concurrency, backpressure, graceful shutdown.

wojons Bundle

bybren-llc Bundle

Stripe payment integration patterns. Use when implementing payment flows, handling webhooks, or working with subscriptions. Routes to existing patterns and provides evidence templates for payment testing.

bybren-llc Bundle

Testing patterns for unit, integration, and end-to-end tests. Use when writing tests, setting up test fixtures, or validating RLS enforcement. Routes to existing test conventions.

citypaul Bundle

Stable consumer-facing API and interface design patterns. Use when designing REST endpoints, cross-team boundaries, or any externally consumed or versioned service contract. Covers contract-first development, error semantics (RFC 9457), REST conventions, pagination, idempotency, rate limiting, and backward compatibility. For an in-process feature or module's coherent responsibility and interface depth, use codebase-design. For TypeScript type patterns and trust-boundary validation, see typescript-strict.

citypaul Bundle

Unix-composable CLI design patterns. Use when building CLI tools, designing command trees, implementing output layers, or testing CLI behavior. Covers stream separation (stdout/stderr), format flags (--json/--plain), exit codes, TTY detection, composability, and error design. Language-agnostic principles; TypeScript implementation patterns in resources/. For API design (REST, HTTP), see api-design.

wojons Bundle

Implement distributed tracing using logs, including trace context propagation, span logging, correlation IDs, and OpenTelemetry integration for observability

citypaul Bundle

Design and evaluate deep modules: cohesive responsibility behind a small, stable caller-facing contract, with information hiding, justified seams, explicit effects, dependency strategy, and behavior-focused tests. Use when designing or changing an in-process module or package contract, consolidating shallow pass-through modules, deciding what to hide, comparing alternative interfaces, or asking whether code should be combined or split for leverage and locality. For physical layout use structure-codebase; for public compatibility use api-design; for a repository-wide scan use improve-codebase-architecture. For an already-selected whole-path requirement to support a calibrated net-mechanism-reduction claim, use reduce-system-complexity.

citypaul Bundle

Design and protect browser-facing BFF and backend HTTP entry points: an explicit public/protected access classification for every production route, a composition-prepared endpoint registrar that installs session, Origin, Fetch Metadata, CSRF, and content-type policy by construction, provider-free authorization inside the application, protected SSE and WebSocket registration, browser session coordination, and automated enforcement gates. Use when adding or reviewing HTTP endpoints, when a tenant or customer can see another's data through a route or any authorization bug is reported on an endpoint, authentication middleware, session cookies, CSRF or Origin policy, realtime streams, login/logout flows, or auditing which routes are public. For whether to adopt a BFF, granularity, aggregation, and upstream identity mediation use bff-design; for physical BFF route layout use structure-codebase; for REST semantics, pagination, and versioning use api-design; for OAuth/OIDC protocol flows use secure-oauth-oidc; for po

kmshdev Bundle

Provides Color usage, foregroundStyle with hierarchical levels, gradients, system colors, and custom ShapeStyle patterns.

kmshdev Skill

This skill should be used when the user asks to "add blur effect", "apply shadow", "adjust opacity/brightness", "use blend modes", "create visual effects", or needs SwiftUI visual effects API reference. Provides view modifiers (blur, shadow, opacity), VisualEffect protocol, blend modes, and Canvas drawing.

kmshdev Skill

Provides material types (ultraThin to ultraThick), shapes (Rectangle, Capsule, Circle), and layout containers.

kmshdev Skill

This skill should be used when the user asks to "add SF Symbols", "animate icons", "use symbol effects", "apply symbol rendering mode", "add bounce/pulse effect", or needs SwiftUI iconography API reference.

jaykim88 Skill

Choose the API protocol (REST / GraphQL / gRPC) by traffic shape and design resources, versioning, and async patterns. Use when adding a new API surface, designing a service boundary, or when clients complain about over/under-fetching. Not for the schema/error envelope details (use api-contract) or per-resource access control (use authorization).

jaykim88 Skill

Define a schema-first API contract — standardized error envelope (RFC 9457), pagination, status codes, consistent JSON shapes. Use when establishing API conventions, before multiple teams consume an API, or when error responses are inconsistent. Not for choosing the protocol or modeling resources (use api-design) or for runtime input parsing at the boundary (use data-validation).

jaykim88 Skill

Design webhooks correctly on both sides — sending (HMAC signing, retries with backoff, at-least-once) and receiving (verify signature on raw body, enqueue + 200 fast, dedupe on event id). Use when adding webhook delivery or consuming a provider's webhooks. Not for internal service-to-service events (use async-messaging) or general outbound-call retry policy (use resilience-patterns).

jaykim88 Skill

Build reliable event-driven flows with the Transactional Outbox pattern — write state and event in one transaction, relay asynchronously, achieve at-least-once delivery + consumer idempotency. Use when an action must reliably trigger downstream work, or when events are lost on crash (dual-write problem). Not for simple background work without state+event reliability (use background-jobs) or outbound HTTP webhook specifics (use webhook-design).

jaykim88 Skill

Run work off the request thread reliably — queue design, retries with exponential backoff + jitter, dead-letter queues, concurrency control, and idempotent handlers. Use when an operation is slow/external, when jobs fail silently, or when retries cause duplicates. Not for write+event transactional reliability — the dual-write problem (use async-messaging Outbox) or webhook-receiver specifics (use webhook-design).

jaykim88 Skill

Validate untrusted input once at the trust boundary and return a typed parsed value (parse, don't validate). Use when adding an endpoint, accepting external input, or when invalid data leaks past the boundary into business logic. Not for defining the API contract/schema itself (use api-contract) or downstream business-rule logic — parse only at the trust boundary.
