What it does

Add A Provider is an agent skill from strapi-community/plugin-rest-cache. Add a new cache provider package to this repository, or modify an existing one. Use when working in packages/provider-rest-cache-, implementing a storage backend, or changing the CacheProvider contract.

Its SKILL.md is about 960 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Redis. The repository describes itself as: Speed-up HTTP requests with LRU cache. The licence is MIT.

When your agent uses it

  • Working in packages/provider-rest-cache-
  • Implementing a storage backend
  • Changing the CacheProvider contract

Example prompts

  • “/add-a-provider”

What it can do on your machine

Read from SKILL.md and the folder at commit af0e7d8. 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

    Shell commands in SKILL.md call:

    • pnpm

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

  • Network

    No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.

    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

Add A Provider loads about 960 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 405 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~960

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.

description
Add a new cache provider package to this repository, or modify an existing one. Use when working in packages/provider-rest-cache-*, implementing a storage backend, or changing the CacheProvider contract.

Adding a cache provider

A provider is a small package that stores and retrieves cache entries. The contract is packages/plugin-rest-cache/server/src/types/CacheProvider.ts — read it first; its comments cite the bugs each decision prevents.

The contract

Required: get(key), set(key, value, maxAge), del(key), keys(), and a ready getter.

Optional: delMany(keys) and clear(). The base class supplies working defaults, so a provider written against the older contract keeps working. Override them when the backing store has batch operations — a purge is otherwise one round trip per key, which on Redis meant roughly 20,000 round trips and 55MB transferred for a 100k-entry cache.

Rules that are not stylistic

maxAge is milliseconds. Do not convert it. cache-manager's ttl is also milliseconds. Converting again is how a configured hour became 41.7 days.

keys() must return unqualified keys, without the store's prefix and without any adapter-internal qualification. @keyv/redis tracks keys as keyv:/api/foo; returning that form makes purge patterns match nothing while the deletes address keys that do not exist.

Keep the package CommonJS. Providers are loaded via createRequire(...)(modulePath). If a dependency is ESM-only — quick-lru v7 is — resolve it through an async static create() rather than making the package ESM. See MemoryCacheProvider.create().

Do not rename the provider class. bootstrap.ts identifies a provider by walking the constructor chain comparing constructor.name, because a provider resolves its own copy of the types bundle and a real instanceof is false. A rename breaks provider loading with a misleading "does not export a CacheProvider instance" error.

Handle interop defensively. keyv v4 exports its constructor directly, v5 exports it as .default, and @keyv/redis exposes only .default from its CJS build. Which one you get depends on what won the hoist in the host application, so accept either:

ts
const keyvModule = require('keyv');
const Keyv = keyvModule.default ?? keyvModule;

Package shape

The entry point must export:

ts
module.exports = {
  provider: 'myprovider',
  name: 'My Provider',
  async init(options, { strapi }) {
    return MyCacheProvider.create(options);
  },
};

The plugin resolves @strapi-community/provider-rest-cache-<name> from the provider name in configuration. Arbitrary npm packages are not yet supported (there is a @TODO in bootstrap.ts).

Cluster safety

If the backing store is distributed, a multi-key delete may span shards. Redis Cluster rejects it outright:

CROSSSLOT Keys in request don't hash to the same slot

The redis provider deletes key by key when store.redis.isCluster, and batches only the tracking-set update, which is a single key. Do the equivalent.

Verifying

bash
pnpm --filter @strapi-community/provider-rest-cache-<name> run build
pnpm run test:smoke     # loads the built provider and exercises it
pnpm run test:deps      # every import must be declared
pnpm run test:e2e:redis # if your provider is redis-shaped
pnpm run test:cluster   # cluster-safety check, needs the built dist

Then run the full memory suite too — the plugin's behaviour is provider-agnostic and regressions show up there.

Documenting it

A new provider needs a page under docs/guide/providers/, an entry in the sidebar (docs/.vitepress/config.js), and a row in docs/guide/providers/index.md. Follow the existing pages: every config sample carries both JavaScript and TypeScript tabs.
