next-cache-components-adoption

next-cache-components-adoption is a skill for Claude Code, Codex from vercel/next.js. It costs 95 tokens per session (7,457 once invoked), scanned A, original, MIT.

A workflow for enabling Cache Components, a Next.js feature that controls which parts of an app can be cached, in an App Router project.

In plain words
What is it for?
Use it to enable Cache Components, apply the related code changes, and bring the app to a passing build.
Why use it?
It helps developers work through the route errors and validation problems that appear when the feature is turned on.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

next-cache-components-adoption scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

next-cache-components-adoption

Enable Cache Components on an app and walk it to a passing build. This skill sequences the work; per-error recipes live in the dev overlay fix cards and the build's terminal output. The migrating to Cache Components guide is the canonical reference for the concepts and per-API recipes this skill applies — consult it whenever the skill steps reference a pattern ("use cache", cacheLife, <Suspense> placement, etc.) and you want the full explanation.

requires

  • App Router project. Cache Components is an App Router feature; cacheComponents: true does nothing for pages/ routes. If the project has a pages/ or src/pages/ tree but no app/ or src/app/ tree, stop and tell the user — Pages → App migration is its own project, not part of this skill. A hybrid app (both pages/ and app/) is fine: the flag affects the app/ routes; pages/ routes are unaffected and don't need opt-outs.

  • A resolved app directory. Locate next.config.{js,ts,mjs,cjs} first: that's the project root, and an agent invoked from a subdirectory would otherwise test for app/ against the wrong cwd and find nothing. Look for app/ and src/app/ under it, and treat every command and glob in this skill as relative to whichever one exists. If both exist, Next.js builds app/ and never looks at src/app/, so its routes are shadowed and unbuilt — tell the user that and ask which tree to migrate instead of picking one.

  • A runnable app. The whole loop verifies against next dev and a browser, so the app has to boot. If it reads a database or required env at import (e.g. an env.ts that throws on a missing DATABASE_URL), confirm it actually starts — with the real environment, or local data you stand up — before step 1. Adoption can't be verified against an app that won't run.

  • Next.js 16.3 or later. That release is where the pieces this skill relies on land: top-level cacheComponents, export const instant, the dev-overlay instant-navigation validation warnings, and the cache-components-instant-false codemod. If next --version reports below 16.3, upgrade first:

    • npx @next/codemod@latest upgrade latest to apply the version-to-version codemods.
    • Read the relevant version upgrade guide (e.g. Version 16) for what the codemod doesn't cover.

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
