roblox-datastores
Persist player data in Roblox with DataStoreService: GetDataStore, GetAsync/ SetAsync/UpdateAsync/IncrementAsync wrapped in pcall, load-on-join and save-on-leave plus BindToClose, retries, and OrderedDataStore leaderboards. Use when saving or loading persistent data in a Roblox experience — when the user mentions DataStore, DataStoreService, GetAsync, SetAsync, UpdateAsync, save player data, or leaderboards. For general Luau scripting use roblox-luau.

# Roblox DataStores Persist data across sessions in Roblox with `DataStoreService`: loading on join, saving on leave and shutdown, safe updates, retries, and ordered stores for leaderboards. Server-side only. ## When to use - Use to save/load player progress (coins, inventory, levels), build persistent leaderboards, or fix data loss, overwrites, and throttling. - Use when server code calls `DataStoreService`, `GetDataStore`, `GetAsync`, `SetAsync`, `UpdateAsync`, or `GetOrderedDataStore`. **When *not* to use:** general scripting, services, remotes, the client/server split → `roblox-luau`. High-frequency temporary state (matchmaking, per-round) → memory stores (a different service). Engine-agnostic persistence theory → `save-systems`. ## Core workflow 1. **Enable Studio access once.** File → Game Settings → Security → *Enable Studio Access to API Services* (use a test place; Studio hits live data). DataStores work only from server `Script`s, never `LocalScript`s. 2. **Get a store, then read/write by key.** `DataStoreService:GetDataStore("Name")`; key per player is usually `"Player_" .. player.UserId`. 3. **Wrap every call in `pcall`.** `GetAsync`/`SetAsync`/`UpdateAsync` are network
- When to use
- Core workflow
- Patterns
- 1. Load on join (pcall-guarded)
- 2. Save with UpdateAsync (multi-server safe)
- 3. Save on leave AND on shutdown
- 4. Retry with backoff (transient failures)
- 5. Increment a counter
- 6. Leaderboard with OrderedDataStore

What does the roblox-datastores skill do?
Persist player data in Roblox with DataStoreService: GetDataStore, GetAsync/ SetAsync/UpdateAsync/IncrementAsync wrapped in pcall, load-on-join and save-on-leave plus BindToClose, retries, and OrderedDataStore leaderboards.

How do I install it?
Run `npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill roblox-datastores --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From gamedev-skills/awesome-gamedev-agent-skills, a repository with 406 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
