## What it does

The skill loads when you create or edit a FiveM resource, an `fxmanifest.lua`, a `client*.lua` or `server*.lua`, ask how events and exports work, or bring a bug that needs server console or F8 logs.

Eight reference files sit behind it: resource structure, manifest, client/server split, events, exports, debugging, optimization and doc links. The rules are strict about a few things. The manifest needs `fx_version 'cerulean'` and `game 'gta5'`, networked events go through `RegisterNetEvent`, and money or item transactions stay on the server. `GetInvokingResource()` returns nil for any net event that crosses the network, so it is not an authentication check — validate types, ranges and server-owned state instead.

Choosing which side runs what is still your call; the skill gives the rules and a decision table. Event names are advised to follow `resource:side:action`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add germanfndez/fiveai-skills --skill fivem-basics -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/fivem-basics/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/fivem-basics/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add germanfndez/fiveai-skills --skill fivem-basics -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/fivem-basics/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add germanfndez/fiveai-skills --skill fivem-basics -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/fivem-basics/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install germanfndez/fiveai-skills fivem-basics
```

2. **Manually: put the files in place**
- File: `.github/skills/fivem-basics/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add germanfndez/fiveai-skills --skill fivem-basics -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/germanfndez/fiveai-skills --path skills/fivem-basics
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/fivem-basics/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add germanfndez/fiveai-skills --skill fivem-basics -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/germanfndez/fiveai-skills/tree/HEAD/skills/fivem-basics/SKILL.md

## When to use it
- split a resource into client, server and shared folders
- write an `fxmanifest.lua` with the right entries
- pick between `TriggerServerEvent`, `TriggerClientEvent` and a plain `TriggerEvent`
- move money and item checks to the server
- work out whether you need server logs or F8 logs

## Example prompts
- Create a FiveM shop resource: the client draws the menu, the server checks the money
- Why did `GetInvokingResource()` return nil inside a net event handler?
- Split this script into client and server and validate the handler arguments

# FiveM basics

Resource structure, fxmanifest, client/server split, events, exports and debugging for FiveM Lua.

## Activation Contract

Load this skill when the user creates or edits any FiveM resource, `fxmanifest.lua`, `client*.lua` or `server*.lua`, asks how client/server, events or exports work, or reports a bug that needs server vs F8 logs.

## Hard Rules

- Manifest: `fx_version 'cerulean'` and `game 'gta5'` (or `'rdr3'` / `'common'`); every client-served file goes in `files`.
- Register networked events with `RegisterNetEvent`; local-only events use `AddEventHandler` alone, never `RegisterNetEvent`.
- Server handlers read the sender from `source`; broadcast with `TriggerClientEvent(event, -1, ...)`.
- `GetInvokingResource()` is nil for every net event that crosses the network; it is not an authentication check. Validate types, ranges and server-owned state instead.
- Never handle money or item transactions on the client; validate and apply on the server.
- No game natives in `shared_scripts` unless guarded by environment.
- Use `PlayerPedId()` not `GetPlayerPed(-1)`; use `#(a - b)` not `GetDistanceBetweenCoords`.
- Prefer `local`; prefer variable `Wait()` over fixed `Wait(0)`.
- Resource names use underscores, no spaces or special characters.

## Decision Gates

| Need | Use |
|---|---|
| Client to server | `TriggerServerEvent(event, ...)` |
| Server to one / all clients | `TriggerClientEvent(event, playerId \| -1, ...)` |
| Same side only | `TriggerEvent` + `AddEventHandler` |
| Data back across the network | a callback (ox_lib / framework), not paired events |
| Single-resource, non-networked call | a plain function, not an event |
| Cross-resource function | `exports` / `server_export` in manifest, `exports.res:fn()` |
| Bug with clean server console | ask for F8 client logs |

## Execution Steps

1. Lay out `client/`, `server/`, `shared/` and the manifest; read rules/structure.md and rules/fxmanifest.md.
2. Decide the side for each piece of logic (natives on client, data and validation on server).
3. Wire communication from Decision Gates; name events `resource:side:action`.
4. Validate every server handler argument; add distance and state checks.
5. Point to https://docs.fivem.net/natives/ for native lookups.

## Output Contract

Return the manifest plus runnable Lua split by side, with event names, validation and `source` handling explicit.

## References

- rules/structure.md — scope, client/server separation, naming.
