Integrate You.com web tools with Vercel AI SDK

**Judgement:** High-quality, domain-specific integration workflow for connecting You.com web tools to Vercel AI SDK projects. Strongly suited for JavaScript/TypeScript developers already using generateText or streamText who want to add web search, agentic browsing, or content extraction. **Strengths:** - Very concrete step-by-step workflow: package installation, env var choice, file selection (existing vs new), and tool selection. - Multiple fully worked examples for generateText and streamText, including Next.js App Router, Express, and a React client. - Correct Anthropic streaming pattern with `stopWhen` and `StepResult`, which addresses a common source of runtime issues. - Clear patterns for standard (`YDC_API_KEY`) and custom environment variables, including how to pass keys into each tool. - Troubleshooting section and implementation checklist that help reduce integration errors. **Key Risks / Limitations:** - Tightly coupled to specific packages and APIs (`@youdotcom-oss/ai-sdk-plugin`, You.com platform, Anthropic models); any upstream breaking changes will require maintenance of this skill. - Examples are Anthropic-centric; developers using other providers may need to adapt patterns without explicit guidance. - Web tools inherently introduce added latency, cost, and dependence on third-party APIs, which the skill does not explicitly help optimize (e.g., caching, rate limiting). - Security and privacy considerations (e.g., what content is sent to You.com, key management beyond env vars) are only lightly touched. **Recommended Scenarios:** - You’re building or extending a Vercel AI SDK-based chat or assistant and want to plug in You.com for live web search or document extraction. - You want clear code templates for integrating tools into `generateText` or `streamText` in Next.js/Express with minimal trial-and-error. - You’re troubleshooting typical integration issues (missing package, env var misconfiguration, Anthropic streaming quirks) and need structured guidance. **Less Ideal For:** - Non-JS/TS stacks or non–Vercel AI SDK environments. - Teams needing deep guidance on performance optimization, security hardening, or generic tool-design patterns beyond the You.com ecosystem.
