Claude skills and agent skills

VercelSkill

write-guide

vercel/next.js/.agents/skills/write-guide/SKILL.md

Generates technical guides that teach real-world use cases through progressive examples.

VercelSkill

next-bundle-optimizer

vercel/next.js/skills/next-bundle-optimizer/SKILL.md

Audit and reduce Next.js browser initial-load work. Use for slow route startup, oversized client bundles, duplicate browser dependencies, or features that can wait for interaction.

VercelSkill

next-cache-components-adoption

vercel/next.js/skills/next-cache-components-adoption/SKILL.md

Turn on Cache Components in a Next.js app and resolve the blocking routes it surfaces. Use when the user wants to enable, adopt, or migrate to Cache Components, flip the `cacheComponents` flag, work through a flood of blocking-prerender / instant validation errors, run the `cache-components-instant-false` codemod, or decide between opting routes out with `export const instant = false` and fixing them in place.

next-cache-components-optimizer

vercel/next.js/skills/next-cache-components-optimizer/SKILL.md

Optimize the meaningful UI available immediately from a Next.js route on an initial load (hard navigation) or named client-side navigation (soft navigation). Encode the goal as a failing @next/playwright instant() e2e and work it to green, one verified route and entry point at a time; the shipped test then guards against regression. Use when asked to grow a static shell, fix a slow first paint or non-instant navigation, diagnose which Suspense boundary blocks useful UI, or add instant() regression coverage. Requires Next.js 16.3+ with Cache Components already adopted.

VercelSkill

next-dev-loop

vercel/next.js/skills/next-dev-loop/SKILL.md

Verify Next.js runtime behavior after editing app code. Use this skill to confirm a change actually works in a running app — not just that it compiles or type-checks. Combines /_next/mcp (Next.js's view) with agent-browser (the browser's view). Requires a running `next dev`.

VercelSkill

next-partial-prefetching-adoption

vercel/next.js/skills/next-partial-prefetching-adoption/SKILL.md

Turn on Partial Prefetching in a Next.js app and work through the insights it surfaces. Use when the user wants to enable or adopt Partial Prefetching, flip the `partialPrefetching` flag, opt routes in with `export const prefetch = 'partial'`, audit `Link prefetch={true}` behavior, preserve existing prefetched UI with `instant()` tests, or resolve the instant-link-prefetch-partial and instant-shell-url-data insights.

VercelSkill

next-partial-prefetching-optimizer

vercel/next.js/skills/next-partial-prefetching-optimizer/SKILL.md

Optimize what selected Next.js client navigations include before the click under Partial Prefetching. Use after Cache Components and Partial Prefetching are adopted when the user wants selected URL-specific UI to be instant, wants reusable content to wait for navigation, or needs to choose between default, viewport, and intent prefetching. Requires Next.js 16.3+.

VercelSkill

add

vercel/turborepo/skills/add/SKILL.md

Add Turborepo to an existing repository in any toolchain Turborepo supports. Use when asked to add, introduce, or set up Turborepo or turbo in a repository that does not use it yet.

VercelSkill

turborepo

vercel/turborepo/skills/turborepo/SKILL.md

Configure and troubleshoot Turborepo repositories. Use when working with turbo.json, task pipelines, caching, Remote Cache, the turbo CLI, filtering, environment variables, package boundaries, monorepo structure, or CI workflows.

adr-skill

vercel/ai/skills/adr-skill/SKILL.md

Create, update, or consult Architecture Decision Records (ADRs). Use when capturing an architecture decision and its rationale, maintaining its lifecycle, checking decisions that govern planned changes, or when a session leads to a new decision affecting future work across multiple layers. Do not use for routine bug fixes or features confined to API internals or a single provider or harness adapter.

list-npm-package-content

vercel/ai/skills/list-npm-package-content/SKILL.md
