API Authentication implements secure API auth with JWT, OAuth 2.0, API keys, and sessions. Use it for login flows, third-party integrations, service-to-service access, and token handling.

API Changelog & Versioning creates changelogs that document breaking changes, deprecations, and migration steps for API consumers. Use it when releasing new API versions or planning upgrades.

API Contract Testing verifies that services honor request and response contracts with consumer-driven tests, schema validation, and tools like Pact. Use it to test microservice communication, catch breaking changes, or validate OpenAPI specs.

API Design Principles helps you design REST and GraphQL APIs with clear resource models, versioning, pagination, and error handling. Use it when creating APIs, reviewing specifications, or setting API standards.

API Error Handling implements standardized API error responses with proper status codes, logging, and user-friendly messages. Use it when building production APIs or adding error recovery and monitoring patterns.

API Filtering And Sorting builds flexible query parsing for filters and sort parameters in search endpoints and data APIs. Use it to validate allowed fields, map operators, and reduce injection risk.

API Gateway Configuration designs and configures gateways for routing, authentication, rate limiting, and request transformation in microservice systems. Use it when setting up Kong, Nginx, AWS API Gateway, or Traefik for centralized API management.

API Rate Limiting implements token bucket, sliding window, and Redis-based limits to protect APIs from abuse. Use it for public APIs, tiered access, and blocking request spikes or denial-of-service attacks.

API Reference Documentation creates developer-facing API docs from OpenAPI specs, including endpoints, auth, errors, and examples. Use it for REST API references, SDK docs, and developer portals.

API Response Optimization reduces payload sizes, adds caching headers, and enables compression to improve API response times and bandwidth use. Use it when tuning endpoints for speed or efficient data transfer.

API Security Hardening protects REST APIs with authentication, rate limiting, input validation, and security headers. Use it when hardening production APIs, reviewing vulnerabilities, or handling injection and CORS issues.

API Testing covers HTTP API tests with Supertest in TypeScript and httpx/pytest in Python. Use it to test REST and GraphQL endpoints, authentication, validation, file uploads, and error handling.

API Versioning Strategy implements versioned endpoints with backward compatibility, adapters, and deprecation headers. Use it when planning breaking changes or guiding clients through migrations.

Aceternity UI adds 100+ animated React components for Next.js with Tailwind and Framer Motion. Use it for hero sections, backgrounds, cards, and other interactive UI patterns.

App Store Deployment publishes iOS and Android apps to App Store Connect and Google Play. Use it when preparing releases, managing signing and versioning, or automating deployment in CI/CD.

Architecture Patterns explains Clean Architecture, Hexagonal Architecture, and Domain-Driven Design for backend systems. Use it when designing new services or refactoring code for clearer boundaries and easier testing.

Auto Animate adds zero-config layout animations to React and other UI components. Use it for list changes, accordions, toasts, and SSR-safe animation setups.

Base UI React helps you build accessible unstyled React components with Floating UI and render props. Use it for dialogs, selects, popovers, tooltips, or Radix UI migrations.

Better Auth integrates Better Auth into TypeScript apps for login, OAuth, 2FA, RBAC, and D1-backed auth flows. Use it when adding authentication or fixing Better Auth adapter and migration issues.

Bun Bundler helps build and bundle JavaScript or TypeScript with Bun’s CLI and Bun.build API. Use it for minification, code splitting, sourcemaps, and browser or Node production builds.

Bun Cloudflare Workers shows how to build and deploy Cloudflare Workers with Bun for local development. Use it for Wrangler setup, bindings like KV and D1, Durable Objects, and R2.

Bun Docker shows how to build and run Bun applications in Docker containers with official oven/bun images, multi-stage builds, Compose, health checks, and security settings. Use it when packaging or deploying Bun services.

Bun Drizzle Integration shows how to use Drizzle ORM with Bun's SQLite driver for typed schemas, queries, relations, and migrations. Use it when setting up or maintaining a Bun-backed SQLite database.

Grill Me runs a /grilling session to pressure-test a plan or design. Use it when you want tough questions that expose gaps, assumptions, and tradeoffs before moving forward.
