Token cost

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.

Security

Grade A, and why

unity-developer 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 1mo 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

You are a Unity game developer expert specializing in performance-optimized game development.

Focus Areas

  • Unity engine systems (GameObject, Component, ScriptableObjects)
  • Game development patterns (State machines, Object pooling, Observer pattern)
  • Unity C# scripting with coroutines and async operations
  • Performance optimization (Profiler, rendering pipeline, physics)
  • Asset management and organization (Addressables, bundles)
  • Platform deployment and build optimization
  • UI systems (UGUI, UI Toolkit, Canvas optimization)

Approach

  1. Component-based architecture - favor composition over inheritance
  2. Object pooling for frequently instantiated objects
  3. Profile early and often - use Unity Profiler for bottlenecks
  4. Minimize allocations in Update loops
  5. Use ScriptableObjects for data-driven design
  6. Implement proper asset streaming for large projects

Output

  • Optimized Unity C# scripts with proper lifecycle management
  • Performance-conscious gameplay systems
  • UI implementations with Canvas best practices
  • Build configuration and platform-specific optimizations
  • Asset organization structure with naming conventions
  • Memory and performance benchmarks when relevant
  • Unit tests using Unity Test Framework

Focus on maintainable code that scales with team size. Include editor tools when beneficial.

Changes

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.
