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 | $0.00034 | $0.00893 |
| Opus 5 | $0.00017 | $0.00447 |
| Sonnet 5 | $0.00007 | $0.00179 |
| Haiku 4.5 | $0.00003 | $0.00089 |
Grade A, and why
project-stage-detect 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.

Steps
1. Scan Code
# Count Luau files
find src/ -name "*.lua" -o -name "*.luau" | wc -l
# Count total lines of code
find src/ -name "*.lua" -o -name "*.luau" -exec wc -l {} + | tail -1
# Look for major systems (directories or modules)
ls src/ServerScriptService src/ServerStorage src/ReplicatedStorage 2>/dev/null
2. Scan Design Docs
# Count GDDs
find design/gdd -name "*.md" | wc -l
# Check for master GDD
ls design/gdd/master-gdd.md 2>/dev/null && echo "EXISTS" || echo "MISSING"
# Check for systems index
ls design/gdd/systems-index.md 2>/dev/null && echo "EXISTS" || echo "MISSING"
3. Scan Assets
# Count assets by type
find assets/images -type f 2>/dev/null | wc -l
find assets/audio -type f 2>/dev/null | wc -l
find assets/models -type f 2>/dev/null | wc -l
4. Check Testing
find tests -name "*.spec.lua" -o -name "*.spec.luau" 2>/dev/null | wc -l
5. Check Production Artifacts
ls production/sprints/*.md 2>/dev/null | wc -l
ls production/milestones/*.md 2>/dev/null | wc -l
6. Check Git History
git log --oneline | wc -l # total commits
git log --since="1 month ago" --oneline | wc -l # recent activity
7. Classify Stage
| Stage | Signals |
|---|---|
| Pre-production | No master GDD, <5 GDDs, <1000 LOC, minimal assets |
| Production | Master GDD exists, systems being built, code growing fast, sprints active |
| Polish | All core systems implemented, bug triage focused, perf work happening |
| Live | Published, version tags exist, patch notes history, active retro cadence |
8. Identify Gaps
For each stage, identify what's missing:
Pre-production gaps
- No game concept?
- No creative pillars?
- No target audience defined?
Production gaps
- No systems-index?
- GDDs without corresponding code?
- Code without corresponding GDDs?
- No tests?
- No CI?
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.

project-stage-detect is a skill published in the GitHub repository CodePhobiia/claude-roblox-game-studio (9 stars, last pushed 4mo ago), licensed MIT. It adds 34 tokens to every session and 893 once invoked, about $0.0002 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.

gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
