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 | $0.00050 | $0.02197 |
| Opus 5 | $0.00025 | $0.01099 |
| Sonnet 5 | $0.00010 | $0.00439 |
| Haiku 4.5 | $0.00005 | $0.00220 |
Grade A, and why
placing-furniture 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 12d 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 — 244 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Placing Furniture
Critical: SCAN BEFORE PLACING
Avoid furniture embedded in floor!
# 1. Scan area
scan = spatial_awareness_scan(center_x=100, center_y=65, center_z=200, radius=5, detail_level="medium")
# 2. Get placement Y from recommendations
placement_y = scan['recommendations']['floor_placement_y'] # e.g., 65
# 3. Place furniture AT that Y using build_schematic
build_schematic(
schematic={
"a": [100, placement_y, 200],
"p": {"C": "oak_stairs[facing=south]", "L": "oak_wall_sign[facing=east]", "R": "oak_wall_sign[facing=west]"},
"l": [[0, "L C R"]]
},
description="Armchair"
)
Common mistake: Floor at Y=64, furniture at Y=64 = EMBEDDED! Use Y=65 (ON floor).

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

placing-furniture is a skill published in the GitHub repository amenti-labs/vibecraft (98 stars, last pushed 7mo ago), licensed MIT. It adds 50 tokens to every session and 2,197 once invoked, about $0.0003 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.

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…
