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 | $0.00120 | $0.02514 |
| Opus 5 | $0.00060 | $0.01257 |
| Sonnet 5 | $0.00024 | $0.00503 |
| Haiku 4.5 | $0.00012 | $0.00251 |
Grade A, and why
roblox-studio 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 9d 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Roblox Studio — build it right, build it once, make it look REAL
Runbook for anything built or edited in Roblox Studio. The tools are the External-MCP tools ext__Roblox_Studio__<tool> (need Multi-Turn + ACPX on). Work as an OPERATOR: preflight, build in a FEW big scripts, verify, report.
STEP 0 — Preflight (ALWAYS, before any build)
external_mcp_status— isRoblox_Studioconnected? If not:external_mcp_reconnect, thenexternal_mcp_wait(a first-run stdio child takes seconds).list_roblox_studios→ if more than one,set_active_studioon the intended one.get_studio_state— a place must be open with the plugin connected.- No Studio connected: STOP and say "Open Roblox Studio with a place, make sure the MCP plugin is running, then say go." Never fake a build.
Tool map
| Want to… | Use |
|---|---|
| Run ANY Luau (terrain, parts, scripts, properties) | execute_luau — the workhorse |
Wait for an async generate_* job |
wait_job_finished |
| See errors / prints | get_console_output |
| Read the scene tree | inspect_instance, search_game_tree |
| AI-generate an organic mesh/model/material | generate_mesh, generate_procedural_model, generate_material (async → poll) |
| Marketplace asset | search_asset → insert_asset |
| Author/read scripts | multi_edit, script_read, script_search, script_grep |
| See the result | screen_capture |
Use execute_luau for deterministic geometry; reserve the generative tools for organic one-off props.
GOLDEN RULES
- Batch — the ENTIRE build in one or a few looping
execute_luauscripts, not one part per call. - Realism = Terrain VOXELS + Perlin noise (below). Never landscape out of
Parts, never symmetric concentric layers. - Wrap every script in
pcall, end withprint("TLM_OK …")(elsewarn(err)), then confirm viaget_console_output. - Correct Luau types —
Vector3.new(x,y,z)takes three NUMBERS."Unable to cast double to Vector3"means you passed a number where a Vector3 belongs: fix it, don't retry unchanged. - Undo-friendly —
ChangeHistoryService:TryBeginRecording(...)/:FinishRecording(...). - Never loop on a failing tool. Two errors → stop, read the console, fix the cause or say so honestly (the executor blocks a 3× repeat anyway).
- Verify, then report. "Done" only after the console (ideally a capture) confirms it.
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-studio is a skill published in the GitHub repository XAIHT/Tlamatini (16 stars, last pushed today), licensed MIT. It adds 120 tokens to every session and 2,514 once invoked, about $0.0006 per session on Opus 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.
