Vercel AI SDK v6 — ToolLoopAgent, useChat, streamText, tool approval, MCP

Prerequisites: a project already on ai@6 (Vercel AI SDK v6); a model provider account/API key (metered, e.g. OpenAI, Anthropic, Google) Install "Vercel AI SDK v6 — ToolLoopAgent, useChat, streamText, tool approval, MCP" for me. It gives my agent @laguagu's ai@6 guide: generateText/streamText with Output structured output (replacing deprecated generateObject/streamObject), the ToolLoopAgent class with tool approval and step control, API routes via createAgentUIStreamResponse, smooth streaming, tool definition with Zod, MCP server integration, middleware patterns, and the useChat hook. Only for codebases already on ai@6 — new projects and ai@7 code should use the ai-sdk-7/ai-sdk skill instead. License note: the skill's frontmatter states no license; the catalog manifest records MIT — manifest takes precedence. Repository: https://github.com/laguagu/claude-code-nextjs-skills/blob/main/skills/ai-sdk-6/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "ai-sdk-6". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. verify my project is actually on ai@6 with `bun add ai@6` or equivalent, save my model provider API key in the vault). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
