Guides REST and GraphQL API creation with endpoint planning, versioning, auth, rate limits, error handling, pagination, and OpenAPI docs to keep designs consistent when building or reviewing services.

Performs security-focused differential review of PRs, commits, and diffs, adapting depth to repo size, tracing git history, estimating blast radius, checking coverage, and producing detailed markdown reports to stop regressions.

Automate Discord workflows through Rube MCP’s Composio toolkits, covering messages, DMs, roles, webhooks, and reactions while respecting permissions and rate limits for reliable bot/user operations.

A specialized guide for building robust and scalable Discord bots from scratch. Covers modern best practices, including the use of slash commands, handling gateway intents, managing rate limits, and implementing sharding. Supports foundational patterns for both Discord.js (JavaScript/TypeScript) and Pycord (Python), ensuring your bot is production-ready and highly stable.

This comprehensive guide details how to configure robust CI/CD pipelines for Documenso integrations using GitHub Actions. It covers best practices for automated unit testing with mocks, comprehensive integration testing against a staging environment, and secure deployment workflows, ensuring code quality and reliability from commit to production.

A comprehensive quick-reference guide to diagnosing and resolving common Documenso API errors. Covers status codes (400, 401, 413, etc.), authentication issues, payload validation, rate limits, and best practices for successful document lifecycle management and API integration.

This skill provides patterns for building highly resilient applications that interact with external APIs. It covers crucial concepts like Exponential Backoff with Jitter, request queuing for bulk operations, and the Circuit Breaker pattern. Use this when your application needs to handle rate limit errors (429), transient network failures, or temporary service outages, ensuring reliable throughput and graceful degradation.

Automate ElevenLabs TTS workflows via Composio MCP by generating speech, exploring voices/models, checking subscription limits, streaming audio, and retrieving historical files.

A comprehensive guide for building robust, event-driven APIs using Webhooks, Server-Sent Events (SSE), and message brokers (e.g., Kafka, RabbitMQ). This skill covers advanced patterns like the transactional outbox pattern, implementing event schemas, managing webhooks with retry logic, and establishing real-time streaming endpoints for asynchronous microservices communication. Ideal for architecting complex, scalable, and resilient systems.

A comprehensive guide to diagnosing and resolving common errors encountered when using the Evernote API. It covers three main exception types—User, System, and Not Found—and provides practical solutions, including ENML validation, rate limit retry mechanisms, and safe resource retrieval patterns, ensuring robust application integration.

This skill helps manage and optimize resource usage and API costs within Evernote integrations. It provides utilities for monitoring monthly upload quotas, compressing images, resizing large files, and performing storage cleanup to prevent exceeding account limits and ensuring efficient data handling.

A comprehensive toolkit designed to debug and troubleshoot Evernote API integrations. It provides deep logging of requests, responses, and timings. Features include an instrumented client wrapper for zero-config tracing, ENML content validation with auto-fix capabilities, and token inspection utilities to diagnose connectivity issues and quota limits.
