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.

What it costs to keep this loaded
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 | $0.00022 | $0.00338 |
| Opus 5 | $0.00011 | $0.00169 |
| Sonnet 5 | $0.00004 | $0.00068 |
| Haiku 4.5 | $0.00002 | $0.00034 |
Grade A, and why
art-bible 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 6d 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.
What it actually says
Art Bible
Purpose
Define a visual direction that artists, UI, technical art, and marketing can execute consistently.
Use When
- the visual style is still vague
- outsourcing or parallel art production is starting
- art consistency is drifting
Inputs
- product pillars
- references
- platform targets
- camera and readability constraints
Process
- state the style pillars and what they exclude
- define shape language, color intent, lighting mood, and material logic
- show readability rules for gameplay-critical visuals
- align the style with production capacity and technical limits
- turn the bible into reviewable asset-class guidance
Outputs
- art bible
- style pillars
- do/dont reference set
- readability rules
Quality Bar
- is usable by content creators without tribal knowledge
- respects quality bars and runtime constraints together
- defines validation and ownership for content flow
Common Failure Modes
- style consistency that ignores gameplay readability
- manual pipeline steps that create drift
- content that cannot be validated before release

Notes
- Keep this skill aligned with the relevant rules layer and current project documentation.
- If engine-specific constraints materially change the workflow, hand off to the matching engine skill or engine-specific reviewer.
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.

art-bible is a skill published in the GitHub repository MRCalderon3D/everything-game-dev-code (81 stars, last pushed 20d ago), licensed MIT. It adds 22 tokens to every session and 338 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.
