At a glance

Implement Fetch API, Caching, and Revalidation strategies in Next.js.

  • Configuring cache behavior

  • Implementing revalidation in Next.js

What it does

Nextjs Data Fetching is an agent skill from HoangNguyen0403/agent-skills-standard. Implement Fetch API, Caching, and Revalidation strategies in Next.js. Use when fetching data, configuring cache behavior, or implementing revalidation in Next.js.

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `evals/evals.json` and `references/usage-examples.md`).

It sits in Backend & APIs, covering Caching. It works with Next.js. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Configuring cache behavior
  • Implementing revalidation in Next.js

Example prompts

  • “/nextjs-data-fetching”

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • nextjs.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Nextjs Data Fetching loads about 512 tokens when it runs, and up to ~778 if it reads all its reference files. Until then it costs about 46 tokens; SKILL.md has 180 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~512
With references · SKILL.md plus every file in references/, read only if the agent opens them
~778

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Data Fetching (App Router)

Priority: P0 (CRITICAL)

[!WARNING] Covers App Router fetch only. For pages/ directory: use getServerSideProps / getStaticProps. Ignore native fetch caching advice below.

Fetch data directly in Server Components using async/await.

Strategies

  • Static: Build-time. fetch(url, { cache: 'force-cache' }).
  • Dynamic: Request-time. fetch(url, { cache: 'no-store' }) or cookies().
  • Revalidated: fetch(url, { next: { revalidate: 60 } }).

Patterns

  • Direct Access: Call DB/Service layer directly. ** not fetch your own /api routes.** Example: export default async function Page() { const user = await db.user.findUnique({ where: { id }, select: { id: true, name: true } }); }
  • Colocation: Fetch exactly where data needed.
  • Parallel: Use Promise.all() to prevent waterfalls.
  • Client-Side: Use SWR/React Query for live/per-user data (no SEO).

Revalidation

  • Path: revalidatePath('/path') - Purge cache for route.
  • Tag: revalidateTag('key') - Purge by tag.

Anti-Patterns

  • No root-level awaits: Wrap slow fetches in <Suspense> to avoid blocking.
  • No useEffect for data fetching: Use SWR or React Query for client-side data.
  • No internal API calls from RSC: Fetch from DB/service layer directly.
