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 | $0.00051 | $0.00903 |
| Opus 5 | $0.00026 | $0.00451 |
| Sonnet 5 | $0.00010 | $0.00181 |
| Haiku 4.5 | $0.00005 | $0.00090 |
Grade A, and why
building-redstone 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Building Redstone
Critical: Block Placement Order
Support blocks FIRST, then dependent blocks! Blocks drop as items if support doesn't exist.
WRONG: 1.wire 2.button 3.blocks → Wire breaks!
RIGHT: 1.platform 2.walls 3.wire 4.button
Attachment Rules
| Block | Support Location |
|---|---|
| redstone_wire, repeater, comparator, carpet, pressure_plate | Y-1 (below) |
| redstone_wall_torch, button, wall_sign | Same Y, offset by facing |
Wall attachment facing: east→block at X-1, west→X+1, north→Z+1, south→Z-1
MCP Tools
build(commands=[
"/fill X Y Z X2 Y Z2 stone", # 1. Support
"/setblock X Y+1 Z redstone_wire", # 2. Redstone
"/setblock X+1 Y+1 Z stone_button[facing=west,face=wall]", # 3. Attachments
])
Logic Gates
NOT: [in]→[block]→[torch]→[out] — Torch inverts signal
OR: Merge two wires at same block
AND: Two torches→junction block→inverting torch→output
XOR: Two comparators in subtract mode, OR their outputs
See gates.md for implementations.
Memory Circuits
RS Latch: Two torches in feedback loop (Set/Reset)
T Flip-Flop: [in]→[dropper↔dropper]→[comparator]→[out] — Toggles state
Timing
Repeater Clock (3 minimum):
build(commands=[
"/setblock X Y Z repeater[facing=east,delay=1]",
"/setblock X+1 Y Z repeater[facing=south,delay=1]",
"/setblock X+1 Y Z+1 repeater[facing=west,delay=1]",
"/setblock X Y Z+1 redstone_wire",
])
Hopper Clock: [hopper→hopper] with comparator. Timing = items × 0.4s
Piston Door (2x2)
build(commands=[
"/setblock X Y Z stone_bricks",
"/setblock X Y+1 Z stone_bricks",
"/setblock X-1 Y Z sticky_piston[facing=east]",
"/setblock X-1 Y+1 Z sticky_piston[facing=east]",
"/setblock X-2 Y Z redstone_wire",
"/setblock X-2 Y+1 Z redstone_wire",
])
Block States
repeater[facing=north,delay=1-4,locked=false]
comparator[facing=south,mode=compare|subtract]
piston[facing=up,extended=false]
sticky_piston[facing=east,extended=true]
observer[facing=north] # watches that direction
lever[face=wall,facing=north]
stone_button[face=wall,facing=east]
What ships with it
2 files 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.

building-redstone is a skill published in the GitHub repository amenti-labs/vibecraft (98 stars, last pushed 7mo ago), licensed MIT. It adds 51 tokens to every session and 903 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.
Other skills, from other repositories
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…
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
playtest-report
Generates a structured playtest report template or analyzes existing playtest notes into a structured format. Use this to standardize playtest feedback collection and analysis.
