fivem-dev — Claude Code skill for FiveM resource development

What fivem-dev does

The skill targets the usual FiveM failure mode: a native or framework call gets invented, and the resource breaks on the server. The agent is told never to guess function names or parameters. When something is unclear it pulls the docs with WebFetch, and if a function does not exist it says so and suggests an alternative.

A content map keeps the agent from loading everything at once. It reads only what the request needs: framework detection, a separate file per framework (QBox, QBCore, ESX), Lua patterns, a NUI guide for HTML/CSS/JS, client-server architecture, thread management, an fxmanifest.lua reference and an ox_lib guide. For GTA V props, vehicles and peds it points you to PlebMasters Forge. Tool access is limited to read, write, edit, glob, grep, Bash and WebFetch.

Network access matters here. Without WebFetch the agent cannot verify a native or an export, so you end up checking everything by hand. Worth knowing before you rely on it in an offline setup.
