Skill UI

This skill provides advanced architectural patterns for optimizing high-volume integrations with the Navan API. It addresses common bottlenecks like rate limiting, sequential calls, and naive pagination by implementing robust solutions such as data-type-specific response caching, controlled parallel fetching with concurrency throttling, efficient cursor-based pagination, and HTTP connection reuse. Use this when building scalable, reliable, and high-throughput systems.

A comprehensive checklist for validating the operational readiness of any Navan API integration before deployment to a live production environment. This guide covers critical areas including credential security (rotation, secret management), robust error handling, rate limit strategies, Single Sign-On (SSO) setup, data synchronization, and compliance auditing (PCI DSS, GDPR). Use this when ensuring mission-critical API stability.

Use this guide when designing a robust, production-grade integration with the Navan API. It details a multi-layered architectural blueprint, including an API Gateway for rate limiting and circuit breaking, a centralized OAuth Token Management Service, secure data synchronization pipelines, and comprehensive monitoring stacks. Ideal for complex enterprise systems requiring reliable connectivity to travel and expense data.

A comprehensive guide to securing Navan integrations and API access. This skill covers OAuth 2.0 best practices, secure credential storage, automated credential rotation, configuring Single Sign-On (SSO) via SAML/OpenID Connect, and implementing automated user lifecycle management using SCIM provisioning. Essential for hardening enterprise-level integrations.

A guide to building resilient software integrations when dealing with external APIs that lack formal versioning, changelogs, or guaranteed backward compatibility. Learn defensive coding patterns, implementing schema drift detection via CLI tools (curl, jq), using fallback field names, and executing gradual feature flag rollouts to maintain production stability.

This skill analyzes complex legal contracts and agreements, identifying unfavorable, high-risk, or one-sided clauses regarding liability, IP, or termination. It generates a structured negotiation strategy document, providing prioritized counter-proposals, recommended replacement language, and professional talking points to guide users through high-stakes contract reviews before signing.

A comprehensive guide for performing end-to-end (E2E) and integration testing on the Nexu → OpenClaw gateway stack. It details the architectural constraints and viable testing methods, emphasizing the use of Vitest for reliable internal function testing (e.g., skill snapshotting, session store logic). Use this when verifying core gateway fixes, testing skill loading after restarts, or simulating complex operational scenarios.

A comprehensive guide detailing five validated architecture patterns for utilizing Notion as a powerful backend database. Use cases include: Headless CMS for blogging, task tracking for project management, building knowledge bases (wikis), handling form submissions, and serving as a data pipeline source. Includes schema design and code examples using TypeScript and Python.

This guide provides a comprehensive reference for diagnosing and fixing common Notion API errors. It covers critical HTTP statuses and specific error codes (such as 401 Unauthorized, 403 Restricted Resource, 404 Object Not Found, 400 Validation Error, and 429 Rate Limited). Use it when debugging failed Notion integrations, managing permissions, or resolving data structure issues for reliable development.

A guide and tooling strategy to optimize programmatic interaction with the Notion API. It helps developers minimize costly rate-limit pressure, reduce engineering overhead, and maximize data throughput by identifying redundant calls, implementing efficient caching, and restructuring database queries. Essential for applications that rely heavily on Notion data synchronization and retrieval.

A comprehensive skill for deploying production-ready Node.js applications that utilize the Notion API to serverless platforms like Vercel, Railway, or Fly.io. This guide implements critical best practices including Notion client singletons for serverless environments, robust rate limit handling (3 req/sec), response caching strategies, and essential health check endpoints to ensure stability and scalability in production.

This guide provides a comprehensive blueprint for implementing enterprise-grade Role-Based Access Control (RBAC) for Notion integrations. It covers the full OAuth 2.0 flow for public, multi-tenant apps, secure per-workspace token storage (with encryption), and layering custom permission models (admin/editor/viewer) over Notion's native permissions. Essential for building robust, secure, and audit-compliant Notion applications.
