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 | $0.00028 | $0.00774 |
| Opus 5 | $0.00014 | $0.00387 |
| Sonnet 5 | $0.00006 | $0.00155 |
| Haiku 4.5 | $0.00003 | $0.00077 |
Grade A, and why
reverse-document 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/reverse-document — Reverse Engineering Design Docs
Delegate to: systems-designer (with lead-programmer for code analysis)
Use When
- Joining a project with no design documentation
- Code has diverged from original design docs
- Need to produce docs for handoff or publishing
- Preparing for
/design-reviewon an unfinished codebase
Steps
1. Scan the Codebase
Identify major systems by:
- Top-level directories in
src/ - Module names
- Service files
- Obvious feature clusters
ls src/ServerScriptService/
ls src/ServerStorage/
ls src/ReplicatedStorage/
2. For Each System, Extract Info
Purpose (from code inspection)
- Module comments (if any)
- File names
- Public function names
- Type definitions
Data Schema
- Find DataStore keys
- Find config tables
- Find Attribute usage
- Find persistent state
grep -rn "DataStore\|Attribute\|ValueObject" src/
Remotes
- Find RemoteEvents / RemoteFunctions created
- Find FireServer / FireClient / InvokeServer / InvokeClient
- Find OnServerEvent / OnClientEvent handlers
grep -rn "RemoteEvent\|RemoteFunction\|OnServerEvent\|OnClientEvent" src/
Client-Server Split
- What files are in ServerScriptService vs. StarterPlayer?
- What's shared via ReplicatedStorage?
UI
- What ScreenGuis exist?
- What buttons/modals/HUDs?
- Sketch the structure
Formulas
- Find numeric operations in gameplay code
- Extract the math into explicit formulas
- Flag magic numbers that should be documented
3. Draft a GDD
For each system, generate a draft GDD using the template. Mark sections as:
[INFERRED FROM CODE]— extracted from implementation[NEEDS USER INPUT]— couldn't determine from code
4. Present for Review
Show each drafted GDD to the user:
- Ask them to fill in sections marked
[NEEDS USER INPUT] - Ask them to correct any
[INFERRED FROM CODE]that are wrong - Look for discrepancies (code says X, user says Y — which is authoritative?)
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.

reverse-document is a skill published in the GitHub repository CodePhobiia/claude-roblox-game-studio (9 stars, last pushed 4mo ago), licensed MIT. It adds 28 tokens to every session and 774 once invoked, about $0.0001 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 2026-09-03.
