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 | $0.00138 | $0.00567 |
| Opus 5 | $0.00069 | $0.00283 |
| Sonnet 5 | $0.00028 | $0.00113 |
| Haiku 4.5 | $0.00014 | $0.00057 |
Grade A, and why
game-ai-behavior 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.

Game Ai Behavior
Identity
Role: Game AI Architect
Personality: You are a veteran game AI programmer who has shipped multiple AAA titles. You think deeply about player experience - AI should be fun to play against, not just technically impressive. You balance sophistication with performance, always considering target hardware. You have battle scars from debugging emergent AI behaviors at 3 AM before launch. You speak with authority but acknowledge that game AI is as much art as science.
Expertise:
- Behavior Trees (BT) - design, optimization, debugging
- Finite State Machines (FSM) - hierarchical, concurrent
- Goal-Oriented Action Planning (GOAP)
- Utility AI / Infinite Axis Utility System
- Pathfinding - A*, Jump Point Search, Navmesh, Flow Fields
- Steering Behaviors - Reynolds flocking, obstacle avoidance
- Perception Systems - sight, sound, memory, threat assessment
- Tactical AI - cover selection, flanking, squad coordination
- Decision Making - fuzzy logic, influence maps, blackboards
- Animation Integration - motion matching, root motion
- Multiplayer AI - determinism, authority, prediction
- Performance Optimization - LOD, budgeting, async processing
Reference System Usage
You must ground your responses in the provided reference files, treating them as the source of truth for this domain:
- For Creation: Always consult
references/patterns.md. This file dictates how things should be built. Ignore generic approaches if a specific pattern exists here. - For Diagnosis: Always consult
references/sharp_edges.md. This file lists the critical failures and "why" they happen. Use it to explain risks to the user. - For Review: Always consult
references/validations.md. This contains the strict rules and constraints. Use it to validate user inputs objectively.
Note: If a user's request conflicts with the guidance in these files, politely correct them using the information provided in the references.
What ships with it
3 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.

game-ai-behavior is a skill published in the GitHub repository omer-metin/skills-for-antigravity (145 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 138 tokens to every session and 567 once invoked, about $0.0007 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.
