What it does

React Hooks is an agent skill from HoangNguyen0403/agent-skills-standard. Write React hooks with clean effect boundaries and measured memoization. Use when working with useEffect, custom hooks, refs, transitions, or hook dependency problems in React.

Its SKILL.md is about 630 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/REFERENCE.md`).

It sits in Frontend & Design, covering React components. It works with React. 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

  • Working with useEffect
  • Hook dependency problems in React

Example prompts

  • “/react-hooks”

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

    No URLs in SKILL.md.

    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

React Hooks loads about 634 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 242 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~634
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.4k

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.

Write React hooks with clean effect boundaries and measured memoization. Use when working with `useEffect`, custom hooks, refs, transitions, or hook dependency problems in React.

React Hooks Expert

Priority: P0 (CRITICAL)

Effects sync external systems. Everything else should stay in render, event handlers, or custom hooks.

Rules

  • Effects: use useEffect only for subscriptions, timers, network lifecycle, DOM APIs, or other external systems.
  • Dependency churn: objects recreated each render cause unstable dependencies; move to primitives, refs, or measured memoization.
  • Effect events: use useEffectEvent when effect logic needs current props/state without widening dependencies.
  • Refs: store mutable, non-render state in useRef.
  • Memoization: add useMemo / useCallback only for measured hotspots or memoized child contracts.
  • Concurrency: use startTransition / useDeferredValue for non-urgent updates.
  • Fetch cleanup: use AbortController when an effect owns request cancellation.

Verify

  • Hooks stay at top level.
  • Effects have cleanup when they subscribe, attach, or schedule.
  • No effect exists only to derive render state from other render state.
  • Dependency arrays reflect real external dependencies.
  • Custom hooks hide internal wiring and expose a small API.

Performance Checklist (Mandatory)

  • Rules of Hooks: Called at top level? No loops/conditions?
  • Dependencies: object/function deps exist for a reason, not by accident?
  • Cleanup: useEffect subscriptions return cleanup functions?
  • Render Count: component re-render excessively?

Anti-Patterns

  • No Missing Deps: Fix logic, don't disable linter.
  • No giant effects: Split unrelated sync concerns.
  • No Derived State: Compute during render, don't useEffect to sync state.
  • No Heavy Init: Use lazy state initialization useState(() => heavy()).
