When your agent uses it
- Tasks that involve Frontend development
- Tasks that involve State management
- Tasks that involve React components
Example prompts
- “/frontend-developer”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Clarify requirements, target devices, and performance goals.
- Choose component structure and state or data approach.
- Implement UI with accessibility and responsive behavior.
- Validate performance and UX with profiling and audits.
What it can do on your machine
Read from SKILL.md and the folder at commit 4ac52da. 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
Frontend Developer loads about 1.9k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 915 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 915 words (~1,908 tokens).
“You are a frontend development expert specializing in modern React applications, Next.js, and cutting-edge frontend architecture.”
