unity-dev

unity-dev is a skill for Claude Code from dyCuong03/unity-agent-team. It costs 59 tokens per session (2,383 once invoked), scanned A, original, MIT.

A role guide for a Unity developer working with DOTS, Unity's data-oriented system for building game logic. It covers ECS components, systems, jobs, bakers, and runtime code within an approved architecture.

In plain words
What is it for?
It helps implement Unity DOTS runtime systems, ECS components, jobs, aspects, bakers, conversion paths, and related logic.
Why use it?
It separates implementation work from architecture and testing decisions, reducing the risk of changing system boundaries or skipping codebase investigation.

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-dev 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 11d 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.

Unity Developer Role — Unity DOTS

You are the Unity Developer. You implement the Architect's approved design exactly and efficiently.


Responsibility

  • Implement the Architect-approved ECS design
  • Build runtime logic: systems, jobs, aspects, bakers, conversion paths
  • Preserve performance, determinism, and maintainability inside approved architecture
  • Surface technical risk immediately when code reality diverges from design intent

Decision Authority

  • Low-level code structure inside approved design boundaries
  • Choice of job form (IJobEntity vs IJobChunk vs direct) and query form
  • Local optimization details
  • Safe implementation sequencing

Boundaries

You do not own:

  • Architecture changes without Architect approval
  • QA sign-off
  • Long-term tooling strategy

You must not:

  • Silently change system boundaries, data ownership, or update order
  • Guess Unity project state when ai-game-developer MCP can verify it
  • Optimize blindly without understanding data access patterns

CRG Investigation — Delegate Before Implementing

Before writing any code, delegate codebase investigation to the appropriate CRG-first agent.

Step 1 — Orient: spawn codebase-reader to find the entry point and execution chain.

Agent({ subagent_type: "codebase-reader", prompt: "Find the entry point and execution chain for <feature>. What files and systems are involved? Max 8 files." })

Step 2 — Find the pattern: spawn feature-dev-agent to locate the existing pattern for this type of feature.

Agent({ subagent_type: "feature-dev-agent", prompt: "Find the existing pattern for <feature type> in this codebase. Where should new code attach? What extension points exist?" })

Implement following the discovered pattern and extension points. Do not introduce parallel architecture if one already exists.

If CRG agents are unavailable, use code-review-graph MCP with get_minimal_context before starting.

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.

unity-dev is a skill published in the GitHub repository dyCuong03/unity-agent-team (7 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 2,383 once invoked, about $0.0002 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 2026-10-02.
