Vercel AI SDK skills Claude skills

The AI SDK repo's skills: one public ai-sdk skill for building with the SDK plus about a dozen maintainer-only skills for the monorepo.

vercel/ai 15 skills Planning, TDD & debugging Backend & databases

Our verdict Recommended with caveats

The ai-sdk skill is sound and from the SDK's maintainers, but most of the repo's skills are internal tooling you should not install for ordinary use.

Install

Skills CLI — pick the agent with -a claude-code or -a codex, add -g for all projects:

npx skills add vercel/ai

Or copy the skill folders you want into ~/.claude/skills/ (Claude Code) or ~/.agents/skills/ (Codex). Other agents. The skills CLI sends anonymous telemetry; DISABLE_TELEMETRY=1 turns it off.

What Vercel AI SDK skills does

The vercel/ai repository holds the AI SDK for TypeScript, and its skills/ folder contains 13 skills. The one meant for users is the ai-sdk skill (use-ai-sdk, about 6 KB). It tells the agent not to write AI SDK code from memory, because APIs and model IDs change, and to read the documentation and source that the ai package ships inside node_modules/ai/docs and node_modules/ai/src, with provider and framework packages bundling their own docs. It covers starting with the AI Gateway (an API key in AI_GATEWAY_API_KEY or OIDC on Vercel), fetching the live model list with curl before choosing a model ID, using ToolLoopAgent rather than hand-rolled tool loops, local-only DevTools, comparing the installed version with npm view ai version, and running the type checker after changes. A migrate-ai-sdk-v6-to-v7 skill is also present. Most of the rest, such as add-provider-package, update-provider-models, adr-skill and edit-package-readme, are for contributors working in the repo itself, and 11 of the 13 are flagged internal in their frontmatter. The README in the dossier is only a pointer to packages/ai/README.md.

Good for

TypeScript developers building chat, agent or structured-output features with the AI SDK
Keeping an agent from using outdated AI SDK APIs
Contributors maintaining the AI SDK monorepo

Not for

Non-TypeScript projects
Users who only want the public skill and not the maintainer skills (install ai-sdk alone)

What's inside depth 2/5

The public skill is a 6 KB SKILL.md with no references; the repo's other 12 skills are mostly short, with a few scripts in adr-skill and list-npm-package-content and two eval files in the repo.

Security review

Review before installing

The repo's skills directory holds maintainer workflows for the Vercel AI SDK plus a user-facing use-ai-sdk skill. Executables are three small local Node scripts for ADR files and a shell script that builds and lists an npm tarball; the only network use is fetching public docs, the AI Gateway model list and a version string. Most of the repository was not available for review.

Worth knowing

Makes network requestsTells the agent to curl the public AI Gateway model list (https://ai-gateway.vercel.sh/v1/models) and to read https://ai-sdk.dev docs; update-harness-dependencies/SKILL.md:75 curls https://releases.fx.sh/latest.txt for a version number.skills/use-ai-sdk/SKILL.md:47
Needs an API key for its own serviceAdvises setting AI_GATEWAY_API_KEY (or Vercel OIDC) in the app's environment; keys are used for the Vercel AI Gateway and provider SDKs, not collected by the skill.skills/use-ai-sdk/SKILL.md:36
Installs packages or toolsMaintainer skills run pnpm update --latest / pnpm install for AI SDK harness packages, and migrate-ai-sdk-v6-to-v7 tells the agent to upgrade ai and @ai-sdk/* packages in the user's project.skills/update-harness-dependencies/SKILL.md:60
Relies on a CLI or package we could not reviewRelies on pnpm, tar, and (in other skills) rg and jq; the AI SDK npm packages that use-ai-sdk points to are not part of the reviewed files.skills/list-npm-package-content/scripts/list-package-files.sh:5
Contains compiled binariesTwo example skill archives (examples/ai-e2e-next/data and examples/ai-functions/data island-rescue-skill.zip) are binary and were not read; they are SDK example fixtures, not installable skills.examples/ai-functions/data/island-rescue-skill.zip

What we checked

The repository (9606 files) on Oct 29, 2026. Not a full review: 9465 of 9606 files were not downloaded (large repository; we reviewed the skill folders); it contains compiled binaries or archives we cannot read; it relies on code outside the repository: Two island-rescue-skill.zip example archives; Most of the repository (about 9,400 readable source, config and example files are not in the local copy), including .claude/settings.json and .agents/skills referenced in the inventory; npm packages ai, @ai-sdk/* and the pnpm/rg/jq tools that the skills invoke.

NVIDIA SkillSpector static scan: 6 pattern hits (Excessive Agency 4, Privilege Escalation 1, MCP Rug Pull 1). The six hits are documentation: '.npmrc' in a list of files npm always excludes, 'without asking' in an ADR philosophy sentence, and an 'npx skills add vercel/ai' install line in the README template.

A review, not a certification. Skills change after we check them — read the files before installing.

License

GitHub reports NOASSERTION and no LICENSE file is in our copy of the skills; check the repository before reuse.

Can it run unattended?

Not really. A guidance skill for interactive coding; it has no loop or verification structure beyond running the type checker.

FAQ

What are the Vercel AI SDK skills?

Skills stored in the vercel/ai repo. The main one, ai-sdk, helps an agent build with the AI SDK by pointing it at version-matched docs bundled in node_modules instead of its memory. The others mostly support people who work on the SDK itself.

How do I install the ai-sdk skill?

Use the skills CLI (npx skills add vercel/ai) and choose the ai-sdk skill, or copy the skills/use-ai-sdk folder into your agent's skills directory. The project needs the ai package installed for the docs to be available locally.

Why does the skill tell the agent not to trust its memory?

The SDK's APIs and model IDs change often, so the skill requires checking the docs and source for the installed version, and fetching the current model list, before writing code.

Vercel AI SDK skill vs the cloudflare/skills agents-sdk skill?

They target different frameworks. This one is for the TypeScript AI SDK (generateText, streamText, useChat); Cloudflare's agents-sdk skill is for building agents on the Cloudflare Agents SDK and Workers.
