- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Tasks that involve React components
- Tasks that involve Performance optimization
What it does
Component Development is an agent skill from programming-in-th/programming.in.th. Use when creating or modifying React components. Ensures proper Server/Client component patterns, performance optimization, and accessibility.
Its SKILL.md is about 200 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 Frontend & Design, covering React components and Performance optimization. The repository describes itself as: Site component of programming.in.th. The licence is AGPL-3.0.
When your agent uses it
- Modifying React components
- Tasks that involve React components
- Tasks that involve Performance optimization
Example prompts
- “/component-development”
Requirements
- Pre-approved tools (allowed-tools): Read, Edit, Write, Glob, Grep
What it can do on your machine
Read from SKILL.md and the folder at commit 79ad808. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadEditWriteGlobGrep
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
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
Component Development loads about 198 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 44 words of instructions outside code blocks.
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
The full file from programming-in-th/programming.in.th at commit 79ad808, republished under its AGPL-3.0 licence (© programming-in-th). 44 words, ~198 tokens.

See React patterns for full reference.
Quick rules:
- Default to Server Components (no directive)
- Use
'use client'only for:onClick,useState,useEffect, browser APIs - Push client boundary to smallest component
- Tailwind only, use
dark:variants
Example:
// Server Component (default)
export function TaskCard({ task }: { task: Task }) {
return <div className="p-4 dark:bg-gray-800">{task.title}</div>
}Checklist: Minimal client components, dark: variants, accessible inputs.
