## What it does

The skill guides agent behavior across Roblox development tools, including Rojo, Wally, pesde, Selene, StyLua, and Lune. It defines how to manage packages, generate sourcemaps for `luau-lsp`, and pin tools using Rokit instead of the archived Aftman. It also covers CI setup, where logic, file, HTTP, and engine suites must be separated.

Source of truth comes first. An agent must distinguish between Roblox Studio and the local disk before touching any file. The `rojo syncback` command only pulls saved-place edits rather than running a live two-way sync, so running a dry run first is mandatory. For script writes via plugins or MCP, the toolchain requires `ScriptEditorService:UpdateSourceAsync` with `ChangeHistoryService` recordings to prevent clobbering open editor tabs.

In CI pipelines, StyLua and Selene run strictly in check mode to prevent silent file rewrites. CI gates depend on parsed test counts and output rather than plain exit codes.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-tooling -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-tooling -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-tooling -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install TabooHarmony/roblox-brain roblox-tooling
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-tooling -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/TabooHarmony/roblox-brain --path skills/tools/roblox-tooling
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add TabooHarmony/roblox-brain --skill roblox-tooling -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/TabooHarmony/roblox-brain/tree/HEAD/skills/tools/roblox-tooling/SKILL.md

## When to use it
- configure Rojo build rules and sourcemap generation for luau-lsp
- manage project dependencies and manifests using Wally or pesde
- enforce Selene linting and StyLua formatting in CI check mode
- update scripts safely inside Studio using ScriptEditorService
- pin project toolchain versions with Rokit

## Example prompts
- Help me set up Rojo and pesde for a new Roblox project using Rokit for tool management.
- Fix our CI workflow so StyLua and Selene run in check mode without rewriting files.
- Show me how to run rojo syncback safely with a dry run before pulling Studio changes.

# roblox tooling

## When to Load

Load for filesystem workflows, tool/package pins, linting, sourcemaps, and CI.

## Quick Reference

- Rojo when files own the truth; Wally for manifests+lockfile (explicit realm). Pin tools via the project's manager; new projects lead with Rokit (Aftman archived, reads `aftman.toml`).
- Selene + StyLua check-mode in CI (no silent rewrites); Lune for standalone Luau; Rojo sourcemap for editor tooling.
- CI gates on parsed results and counts, not exit codes; split logic/file/HTTP/engine suites (full.md).
