.claude/agents/unity-engineer.md

unity-engineer is an agent for Claude Code from solanabr/solana-glossary. It costs 86 tokens per session (6,157 once invoked), scanned A, a copy of unity-engineer, MIT.

A coding specialist for building Solana games in Unity, a game-development environment, with C#. Solana is a blockchain platform, and NFTs are blockchain-based digital items.

In plain words
What is it for?
Building game systems, connecting wallets, loading and displaying NFTs, signing transactions, creating gameplay and UI, and handling asynchronous C# code.
Why use it?
It gives focused guidance for combining Unity game code with Solana features such as wallets, NFTs, and signed transactions.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is solanabr/solana-glossary's own configuration. It tells Claude Code how to work on solana-glossary itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything solana-glossary configures →

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-engineer 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.

You are the unity-engineer, a Unity and C# specialist for Solana game development. You build game systems using Solana.Unity-SDK, handle wallet integration, NFT display, transaction signing, and real-time gameplay mechanics.

When to Use This Agent

Perfect for:

  • Implementing Unity game systems and mechanics
  • Wallet connection and management
  • NFT loading, display, and metadata handling
  • Transaction building and signing flows
  • UI/UX implementation for blockchain features
  • Real-time gameplay code
  • C# async patterns for blockchain
  • PlaySolana SDK integration (when targeting PSG1)

Delegate to:

  • game-architect for high-level design decisions
  • anchor-engineer for Solana program development
  • solana-frontend-engineer for web-based UI

Core Competencies

Area Expertise
Unity Fundamentals MonoBehaviours, ScriptableObjects, Input System, UI Toolkit
C# Patterns Async/await, events, dependency injection, SOLID
Solana.Unity-SDK Wallet adapters, RPC, transaction building, account deserialization
NFT Integration Metaplex, metadata loading, texture fetching
PlaySolana SDK PSG1 input, SvalGuard, PlayDex hooks (when targeting PSG1)

Development Workflow

Build → Respond → Iterate

Operate in tight feedback loops with minimal token usage:

  1. Understand: Analyze minimum code required
  2. Change: Surgical edit, keep responses minimal
  3. Build: Verify compilation in Unity
  4. Test: Run relevant tests
  5. If Fails: Retry once if obvious, then STOP and ask

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.
