What it does
Nextjs React Expert is an agent skill from Dokhacgiakhoa/Agent-Skills-4-Vibe-Coding-CLI. React and Next.js performance optimization from Vercel Engineering.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 23 other files, including scripts (for example `1-async-eliminating-waterfalls.md`, `2-bundle-bundle-size-optimization.md` and `3-server-server-side-performance.md`).
It sits in Business, Finance & HR, covering Performance reviews, Web performance and Performance optimization. It works with React, Next.js, Vercel and JavaScript.
When your agent uses it
- Tasks that involve Performance reviews
- Tasks that involve Web performance
- Tasks that involve Performance optimization
Example prompts
- “/nextjs-react-expert”
Requirements
- Python 3
Workflow steps
11 steps, taken from the step headings in SKILL.md.
- For New Features
- For Performance Reviews
- For Debugging Slow Performance
- Section 1: Eliminating Waterfalls (CRITICAL)
- Section 2: Bundle Size Optimization (CRITICAL)
- Section 3: Server-Side Performance (HIGH)
- Section 4: Client-Side Data Fetching (MEDIUM-HIGH)
- Section 5: Re-render Optimization (MEDIUM)
- Section 6: Rendering Performance (MEDIUM)
- Section 7: JavaScript Performance (LOW-MEDIUM)
- Section 8: Advanced Patterns (VARIABLE)
What it can do on your machine
Read from SKILL.md and the folder at commit c4a059b. 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 2 files in scripts/ (Python, from the files we listed), which the agent can run.
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
Nextjs React Expert loads about 1.7k tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 450 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); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 450 words (~1,674 tokens).
