Automated summary
This skill provides expert assistance for configuring and optimizing Vite: plugins, resolve aliases, a dev server with proxying, environment variables, and production chunk splitting.
Strengths
- Ships a complete, reusable vite.config.ts template with aliases, proxy and manualChunks
- Covers the three core areas: configuration, plugin authoring and build optimization
- Addresses both the development environment (HMR, port, proxy) and production output
Limitations
- The chunking example stops at a single React vendor chunk with no advanced splitting strategy
- Does not explain how to actually write plugins or the underlying Rollup APIs
- Little concrete guidance on environment variables despite listing them as a capability
Use it when you need to write or fix a Vite config, add a dev proxy, or trim production bundle size.
Avoid it for questions about competing bundlers (webpack, standalone esbuild) or for application debugging unrelated to build configuration.
Security analysis
CautionThe skill is a straightforward Vite configuration helper with no obfuscated payloads, exfiltration, credential access, or destructive commands. Its risk comes only from the declared tool set: Bash, Write, and Edit give an agent powerful local capabilities for legitimate build/config work, so it falls into the 'caution' category rather than 'safe'.
- •Declares Bash, Write, and Edit permissions, which allow arbitrary command execution and file modification when invoked by an agent
- •No explicit guardrails limiting Bash usage to build/dev commands (e.g., no instruction to avoid destructive commands or network installs)
Examples
Add a '@' alias to my src folder and proxy /api to http://localhost:8080 in my vite.config.ts.My Vite production bundle is one giant file — configure manualChunks to split React and other vendor deps.Set up a Vite config for a React app with the React plugin and a custom dev server port of 3000.name: vite description: Vite configuration, plugins, optimization, HMR, and build customization. allowed-tools: Read, Write, Edit, Bash, Glob, Grep

From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/vite-configuration-and-optimization-mmbizjl5/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/vite-configuration-and-optimization-mmbizjl5' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/vite-configuration-and-optimization-mmbizjl5/download' --output '.skill-downloads/vite-configuration-and-optimization-mmbizjl5/SKILL.md.part' && mv '.skill-downloads/vite-configuration-and-optimization-mmbizjl5/SKILL.md.part' '.skill-downloads/vite-configuration-and-optimization-mmbizjl5/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
Tools declared by the author (check availability in your agent): Read, Write, Edit, Bash, Glob, Grep
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/vite-configuration-and-optimization-mmbizjl5/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
