What it does

Initialize is an agent skill from reactive/data-client. Setup, install, and onboard new developers to Reactive Data Client monorepo - nvm, yarn, build, test, getting started guide

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Monorepo tooling. The repository describes itself as: Async State Management without the Management. REST, GraphQL, SSE, Websockets. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Monorepo tooling

Example prompts

  • “/initialize”

Requirements

  • Node.js

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Install prerequisites
  2. Install dependencies
  3. Build the project
  4. Run tests
  5. Project familiarization
  6. Optional: Start website locally

What it can do on your machine

Read from SKILL.md and the folder at commit 02c0932. 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:

    • yarn
    • nvm

    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):

    • dataclient.io
    • github.com
    • discord.gg

    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

Initialize loads about 588 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 220 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~588

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.

Steps

  1. Install prerequisites

    • Install Node.js >= 14 via nvm: nvm install
    • Enable Corepack for Yarn 4: corepack enable
    • Verify Yarn: yarn --version (should be 4.x)
  2. Install dependencies

    • Run yarn install from repo root
    • This installs all workspace dependencies
  3. Build the project

    • Run yarn build to build all packages
    • This runs TypeScript compilation and Babel transforms
  4. Run tests

    • Run yarn test to verify everything works
    • Tests use Jest with projects: ReactDOM, Node, ReactNative
  5. Project familiarization

    • Review monorepo structure:
      • packages/endpoint – Base endpoints and declarative schemas
      • packages/rest – REST modeling (resource(), RestEndpoint)
      • packages/core – Framework-agnostic normalized store
      • packages/react – React hooks (useSuspense, useLive, useQuery)
      • packages/vue – Vue 3 composables
      • packages/normalizr – Schema/Entity/normalization
    • Read official docs
    • Explore example apps in examples/
  6. Optional: Start website locally

    • Use workspace task "website: start" or cd website && yarn start
    • Documentation site runs on localhost

Onboarding Checklist

  • Node.js >= 14 and Yarn 4 ready
  • yarn install completed without errors
  • yarn build succeeds
  • yarn test passes
  • Reviewed packages/ structure
  • Read CONTRIBUTING.md
