What it does

React Useeffect is an agent skill from viclafouch/meme-studio. Audit React components for unnecessary useEffect hooks. Use when reviewing code that has useEffect, useState patterns, or when asked to optimize React components. Identifies anti-patterns like derived state, chained effects, event-driven effects and suggests better alternatives (computed values, useMemo, key prop, event handlers, useSuspenseQuery).

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `alternatives.md` and `anti-patterns.md`).

It sits in Frontend & Design, covering React components and Event-driven systems. It works with React. The repository describes itself as: 📌 A complete and fast website building in Next.js for creating and sharing "internet memes".

When your agent uses it

  • Reviewing code that has useEffect
  • UseState patterns
  • Asked to optimize React components

Example prompts

  • “/react-useeffect”

What it can do on your machine

Read from SKILL.md and the folder at commit d8fa0be. 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 Useeffect loads about 375 tokens when it runs. Until then it costs about 92 tokens; SKILL.md has 126 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~375

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 126 words (~375 tokens).

“Effects are escape hatches - they should primarily synchronize with external systems. Many common use cases don't actually require Effects.”
