Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.03359 |
| Opus 5.5 | $0.00018 | $0.01344 |
| Sonnet 5.5 | $0.00009 | $0.00672 |
| Haiku 4.5 | $0.00005 | $0.00336 |
Grade A, and why
roblox-datastores scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 231 lines — stays where its author put it; the contents beside it link to each section on GitHub.
roblox-datastores
Keep persistence on the server. For concurrent writes, use a pure UpdateAsync transform; after a write error, reconcile the backend state before retrying or compensating.

For temporary queues, lobbies, and caches, use MemoryStoreService. Read types-of-datastores.md when choosing a store.
Cross-reference:
- roblox-networking/SKILL.md for server-authoritative validation before any write.
- roblox-core/SKILL.md for service acquisition patterns, pcall discipline, and Luau serialization rules.

Choose a store
-
Is the data temporary/ephemeral, high-churn, or only needed while servers are active (queues, lobbies, rate counters, short caches)?
→ Use MemoryStoreService (queues, sorted maps, etc.). DataStores are overkill and more expensive/slower. See references and official comparison. -
Do you need sorted numeric queries for leaderboards or rankings?
→ Use OrderedDataStore (via GetOrderedDataStore). Values must be integers. No versioning/metadata. Special GetSortedAsync + DataStorePages iteration. Limits differ (see references/limits...).

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

roblox-datastores is a skill published in the GitHub repository nonlooped/roblox-suite (25 stars, last pushed 9d ago), licensed MIT. It adds 46 tokens to every session and 3,359 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
