# roblox tooling

## When to Load

- Load when setting up a filesystem workflow, pinning tools, adding packages, configuring lint or format checks, generating a sourcemap, or building CI for a Roblox project.

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

## Quick Reference

- Use Rojo when the source of truth should live in files and sync or build into Studio.

- Use Wally only when the project wants package manifests and a lockfile; keep package scope and server/client placement explicit.

- Pin tools with the project's existing manager; for a new project lead with Rokit (Aftman is archived, but Rokit reads existing `aftman.toml` projects).

- Run Selene and StyLua in check mode in CI. Do not let a formatter rewrite a contributor's branch silently.

- Use Lune for standalone Luau scripts or test helpers when its standard libraries fit the task.

- Generate a Rojo sourcemap for editor tooling when the project needs Roblox-aware navigation.

+ - CI must check test results and expected counts, not merely exit codes. Separate logic, file/HTTP, and engine suites; see full.md.

- **Source-of-truth first.** Know whether the place lives in Studio, in files (Rojo), or in a bidirectional sync before editing; never assume both sides match. `rojo syncback` pulls saved-place edits into files (dry-run/list first); it is a file pull, not live two-way sync. Name optional tools (Selene, StyLua, luau-lsp, Lune, Wally, pesde) when relevant; TestEZ is archived and belongs only in projects already using it. Do not impose a tool on a project that does not use it. Details in `references/full.md` §§1b–1c.

+ **Source-of-truth first.** Identify Studio vs files before editing; never assume they match. `rojo syncback` pulls saved-place edits, not live two-way sync; preview with dry-run/list. Follow existing tooling; do not impose optional tools. TestEZ is archived: keep where used, not as a new default. See full.md §§1b–1c.

**Need the details?** Load `references/full.md` for setup, file layout, and CI examples.
