optimizely-pattern-extractor

optimizely-pattern-extractor is an agent for coding agents from smithdak/claude-marketplace. It costs 20 tokens per session (1,708 once invoked), scanned A, original, MIT.

An analysis agent that examines an Optimizely CMS codebase, a system for managing website content, to find its coding patterns.

In plain words
What is it for?
It studies content models, services, inheritance, attributes, naming, dependency injection, method patterns, and error handling.
Why use it?
It helps create project-specific coding guidance when the project’s conventions are spread across many files.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods
npx agentmods add agents/smithdak/claude-marketplace/pattern-extractor
Clone the repo
git clone --depth 1 https://github.com/smithdak/claude-marketplace

Or install optimizely, the plugin that ships this one along with the rest of its 5 skills, 4 commands, 10 agents.

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-pattern-extractor 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 3d 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.

Optimizely Pattern Extractor Agent

Learn project-specific patterns, conventions, and architectural decisions to generate custom AI skills.

Extraction Areas

1. Content Type Patterns

Extract content type inheritance and structure patterns:

Glob: **/Models/Pages/**/*.cs
Glob: **/Models/Blocks/**/*.cs
Glob: **/Models/Media/**/*.cs

Extract:

  • Base class hierarchy (e.g., SitePageData, SiteBlockData)
  • Common property patterns across content types
  • Attribute usage (Display, Required, AllowedTypes)
  • GUID naming patterns
  • GroupName conventions

Example Pattern:

// Project pattern: All pages inherit from SitePageData
public abstract class SitePageData : PageData
{
    [Display(GroupName = "SEO")]
    public virtual string MetaTitle { get; set; }

    [Display(GroupName = "SEO")]
    [StringLength(160)]
    public virtual string MetaDescription { get; set; }
}

2. Service Patterns

Extract service layer patterns:

Glob: **/Services/**/*.cs
Glob: **/Business/**/*.cs
Grep: interface I\w+Service
Grep: class \w+Service

Extract:

  • Interface definitions
  • Constructor injection patterns
  • Common method signatures
  • Error handling approaches
  • Async patterns

3. Controller Patterns

Extract controller conventions:

Glob: **/Controllers/**/*.cs
Grep: : PageController<
Grep: : ContentController<
Grep: : BlockController<

Extract:

  • Base controller usage
  • Action naming conventions
  • View model construction
  • Route patterns

4. View Patterns

Extract Razor view conventions:

Glob: **/Views/**/*.cshtml

Extract:

  • Layout structure
  • Partial view organization
  • Tag helper usage
  • Content rendering patterns

5. Initialization Patterns

Extract initialization module patterns:

Glob: **/Initialization/**/*.cs
Grep: IInitializableModule
Grep: IConfigurableModule

Extract:

  • Module organization
  • Dependency declarations
  • Configuration patterns
  • Event subscriptions

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.
