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 | $0.00025 | $0.00339 |
| Opus 5.5 | $0.00010 | $0.00136 |
| Sonnet 5.5 | $0.00005 | $0.00068 |
| Haiku 4.5 | $0.00003 | $0.00034 |
Grade A, and why
ai-behavior-patterns 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 10d 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
Ai Behavior Patterns
Purpose
Design maintainable AI behavior structures for decision-making, navigation, combat, and systemic interaction.
Use When
- NPC behavior needs structure
- AI tuning is opaque
- behavior authoring is hard to debug
Inputs
- enemy or NPC roles
- world rules
- combat or systemic constraints
- performance targets
Process
- define behavior goals and state or decision model
- separate sensing, decision, and action execution
- create tuning hooks and readable debug outputs
- handle fail states, navigation issues, and fallback behavior
- profile high-density scenarios early
Outputs
- AI behavior model
- tuning hooks
- debugging checklist
- performance risk notes
Quality Bar
- makes ownership, state flow, and failure behavior explicit
- improves maintainability without over-abstracting
- supports testing, debugging, and safe iteration
Common Failure Modes
- coupling systems through hidden globals or timing assumptions
- writing logic that is hard to test or debug
- optimizing the wrong layer before measuring

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.

ai-behavior-patterns is a skill published in the GitHub repository MRCalderon3D/everything-game-dev-code (96 stars, last pushed 11d ago), licensed MIT. It adds 25 tokens to every session and 339 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-10.

asset-audit
Audits game assets for compliance with naming conventions, file size budgets, format standards, and pipeline requirements. Identifies orphaned assets, missing references, and standard violations.
hotfix
Emergency fix workflow that bypasses normal sprint processes with a full audit trail. Creates hotfix branch, tracks approvals, and ensures the fix is backported correctly.
cgs-bug-report
Use for bug report tasks that capture a reproducible bug with environment, steps, expected/actual behavior, severity, evidence, and owner; produce verification evidence, changed or proposed files, and handoff boundaries.
cgs-bug-triage
Use for bug triage tasks that classify bugs by severity, priority, reproduction confidence, owner role, risk, and release impact; produce verification evidence, changed or proposed files, and handoff boundaries.
cgs-bugfix
Use for bugfix tasks that fix a bounded bug with reproduction evidence, minimal change, regression coverage, and handoff notes; produce verification evidence, changed or proposed files, and handoff boundaries.
cgs-dev-story
Use for dev story tasks that turn a design or bug into an implementation-ready story with owner, files, acceptance tests, and dependencies; produce verification evidence, changed or proposed files, and handoff boundaries.
