Codegen React

What it does

When your agent uses it

• Tasks that involve Project scaffolding

Example prompts

• “/codegen-react”

Requirements

• Node.js
• A Bash shell

Workflow steps

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

1. 1NEVER modify src/main.jsx — it is the entry point and must not be changed
2. 2ALWAYS use named exports: export function ComponentName() {}, NEVER export default
3. 3NEVER create or import index.css — it does not exist and will cause a build error
4. 4Use Tailwind CSS utility classes for all styling (loaded via CDN in index.html)
5. 5Only modify src/App.jsx and create new component files under src/
6. 6src/App.css exists for custom styles but prefer Tailwind classes

What it can do on your machine

Read from SKILL.md and the folder at commit 3c608d8. 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

  Ships 4 files in scripts/ (Shell), which the agent can run.

  Shell commands in SKILL.md call:

  • npm

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

• Network

  No URLs in SKILL.md. Its commands use npm, 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

Codegen React loads about 1.8k tokens when it runs. Until then it costs about 16 tokens; SKILL.md has 667 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~16

When it runs · the whole SKILL.md, loaded when a task matches

~1.8k

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

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); the scripts in this folder are not scanned.
