optimizely-code-quality

A code-review agent for C# projects using Optimizely, a .NET content-management platform. It checks patterns such as blocking asynchronous code and putting business logic in controllers.

In plain words
What is it for?
Reviewing async and await usage, finding synchronous waits on asynchronous work, checking controller responsibilities, and assessing service abstractions.
Why use it?
It helps reveal code patterns that can cause deadlocks or make applications harder to maintain by mixing request handling with business rules.

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

optimizely-code-quality 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 yesterday.

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.

Optimizely Code Quality Agent

Analyze C# code quality, async/await patterns, and service abstractions.

Analysis Areas

1. Sync Over Async

CQ-001: Sync Over Async (Critical)

Blocking on async code can cause deadlocks:

Grep: \.Result(?!\w)
Grep: \.Wait\(\)
Grep: \.GetAwaiter\(\)\.GetResult\(\)
Grep: Task\.Run\(.*\.Wait

Bad Pattern:

public string GetData()
{
    // Deadlock risk!
    var result = _httpClient.GetStringAsync(url).Result;
    return result;
}

Good Pattern:

public async Task<string> GetDataAsync()
{
    var result = await _httpClient.GetStringAsync(url);
    return result;
}

2. Business Logic in Controllers

CQ-002: Business Logic in Controller (Warning)

Controllers should be thin, delegating to services:

Glob: **/Controllers/**/*.cs

Bad Pattern:

public class ArticleController : PageController<ArticlePage>
{
    public IActionResult Index(ArticlePage currentPage)
    {
        // Complex logic in controller - should be in service
        var relatedArticles = _contentLoader
            .GetChildren<ArticlePage>(currentPage.ParentLink)
            .Where(x => x.Category.Intersect(currentPage.Category).Any())
            .OrderByDescending(x => x.StartPublish)
            .Take(5)
            .Select(x => new ArticleViewModel
            {
                Title = x.Heading,
                Excerpt = GetExcerpt(x.MainBody, 200),
                Url = _urlResolver.GetUrl(x.ContentLink),
                Image = GetImage(x.PageImage)
            });
        // More complex logic...
    }
}

Good Pattern:

public class ArticleController : PageController<ArticlePage>
{
    private readonly IArticleService _articleService;

    public ArticleController(IArticleService articleService)
    {
        _articleService = articleService;
    }

    public IActionResult Index(ArticlePage currentPage)
    {
        var model = _articleService.GetArticleViewModel(currentPage);
        return View(model);
    }
}

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.

optimizely-code-quality is an agent published in the GitHub repository smithdak/claude-marketplace (2 stars, last pushed 7mo ago), licensed MIT. It adds 20 tokens to every session and 1,777 once invoked, about $0.0001 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 2026-08-31.
