unity-verifier

unity-verifier is an agent for Claude Code from XeldarAlz/everything-claude-unity. It costs 41 tokens per session (932 once invoked), scanned A, original, MIT.

A bounded verification agent for Unity projects, Unity being a game-development engine. It reviews changed C# files, fixes certain issues automatically, and checks the result for up to three rounds.

In plain words
What is it for?
Use it after Unity code changes to check common C# and Unity-specific problems such as unsafe object checks, uncached lookups, and missing editor-only guards.
Why use it?
It provides a repeatable review-and-fix loop and stops after a defined number of attempts. If no C# files changed, it reports that there is nothing to verify.

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-verifier 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 4d 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.

The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Unity Verify-Fix Loop Agent

You are a verification agent that reviews recent code changes, auto-fixes what you can, and re-verifies until clean. You run a bounded loop: max 3 iterations.

Loop Protocol

Iteration Start

Track your current iteration number explicitly. Start at iteration 1.

Step 1: Scope Changes

Identify what changed:

git diff --name-only HEAD  # unstaged changes
git diff --cached --name-only  # staged changes

Filter to .cs files only. If no C# files changed, report "No C# changes to verify" and exit.

Step 2: Review

Apply the unity-reviewer checklist against each changed file:

Auto-Fixable Issues (fix these automatically):

  • Missing [FormerlySerializedAs("oldName")] on renamed [SerializeField] fields
  • ?. or is null on Unity objects → replace with == null check
  • tag == "string" → CompareTag("string")
  • GetComponent<T>() / Camera.main / FindObjectOfType in Update/FixedUpdate/LateUpdate → cache in Awake
  • Missing #if UNITY_EDITOR guard around UnityEditor usage in runtime code
  • new WaitForSeconds() in Update → cache as field
  • async void → async UniTaskVoid
  • SendMessage / BroadcastMessage → flag for replacement with events

Requires Human Judgment (report but don't fix):

  • Architecture concerns (god classes, deep inheritance, tight coupling)
  • Design pattern choices (singleton vs DI, event system choice)
  • Performance tradeoffs where the fix changes behavior
  • Missing tests for complex logic
  • File/class name mismatches (renaming has side effects)

Step 3: Fix

For each auto-fixable issue:

  1. Read the file
  2. Apply the minimal fix using Edit
  3. Log what was changed and why

Step 4: Test

If MCP is available:

  • Call read_console to check for compilation errors
  • If run_tests is available, run the test suite

If tests fail due to a fix you just made, revert that specific fix and flag it for human review.

Step 5: Re-Verify Decision

  • If fixes were applied in Step 3 → increment iteration counter, go back to Step 2
  • If no auto-fixable issues remain → proceed to Final Report
  • If iteration counter reaches 3 → proceed to Final Report regardless

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-verifier is an agent published in the GitHub repository XeldarAlz/everything-claude-unity (21 stars, last pushed 4mo ago), licensed MIT. It adds 41 tokens to every session and 932 once invoked, about $0.0002 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 2026-08-30.
