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.

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 | $0.00103 | $0.00933 |
| Opus 5 | $0.00051 | $0.00466 |
| Sonnet 5 | $0.00021 | $0.00187 |
| Haiku 4.5 | $0.00010 | $0.00093 |
Grade A, and why
roblox-to-prd 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 11d 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Roblox → PRD
Turn what is already decided into a concise, buildable game design brief (PRD). Do NOT interview the user from scratch — synthesize the concept, conversation, and place state you already have. If the concept has not been pressure-tested yet, run roblox-game-ideas (grilling mode) first.
The tracker location and label vocabulary should have been provided to you in CLAUDE.md / docs/agents/. If not, run setup-roblox-skills.
Why this exists
The single biggest failure mode in AI-built Roblox games is trying to build the whole game in one pass, which leaves everything half-working. A PRD is the contract that a later step (roblox-to-issues) slices into small, independently playtestable pieces. Keep it tight: enough to slice, not a novel.
Process
-
Read the current state. Connect through
roblox-studio-workflowif a place exists. ReadROADMAP.mdif present. Use the game's own vocabulary consistently (currency names, entity names, zone names). -
Sketch the systems, not the whole game. List the major server-authoritative systems and client controllers this concept needs (core loop, economy, save/load, progression, social, UI surfaces). Flag which hold valuable state (currency, inventory, purchases, rewards, progression) — those must be server-authoritative. Confirm the system list matches the user's expectation before writing.
-
Handle UI up front. If the concept has meaningful UI, note whether a Roblox UI design artifact exists yet (see
roblox-game-ux). If not, record an explicit design step rather than treating UI as ready to build. -
Write the PRD using the template, then publish it to the tracker with the
needs-triagelabel/status so it enters the normal flow.
Player Promise
What the player gets, in their words. One or two sentences.
Core Loop
The single repeating loop, start to reward to next goal. Name the first fun action and how fast it happens (target: 10–30 seconds).
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-to-prd is a skill published in the GitHub repository AshExplained/roblox-skills (6 stars, last pushed 2mo ago), licensed MIT. It adds 103 tokens to every session and 933 once invoked, about $0.0005 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 2026-08-31.
