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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.01594 |
| Opus 5 | $0.00009 | $0.00797 |
| Sonnet 5 | $0.00004 | $0.00319 |
| Haiku 4.5 | $0.00002 | $0.00159 |
Grade A, and why
optimizely-experimentation 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 6d 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 Experimentation Agent
Analyze Optimizely Experimentation SDK integration within CMS projects.
Analysis Areas
1. SDK Initialization
EXP-001: Experimentation SDK Without Initialization (Warning)
Check for proper SDK setup:
Grep: Optimizely\.Experimentation
Grep: AddOptimizelyExperimentation
Grep: OptimizelyClient
Grep: IOptimizely
Bad Pattern (SDK referenced but not initialized):
// Package added but not configured
public class MyService
{
private readonly IOptimizely _optimizely;
// But no initialization in Startup...
}
Good Pattern:
// In Startup.cs or Program.cs
services.AddOptimizelyExperimentation(options =>
{
options.SdkKey = Configuration["Optimizely:SdkKey"];
});
2. Feature Flag Patterns
EXP-002: Feature Flags Not Using Typed Accessors (Warning)
Feature flags should use typed accessors:
Grep: IsFeatureEnabled\s*\(\s*["']
Grep: GetFeatureVariable\s*\(
Bad Pattern (String-based):
// Magic strings - error prone
var isEnabled = _optimizely.IsFeatureEnabled("new_checkout", userId);
var discount = _optimizely.GetFeatureVariableDouble("pricing", "discount", userId);
Good Pattern (Typed accessors):
// Typed feature keys
public static class FeatureKeys
{
public const string NewCheckout = "new_checkout";
public const string Pricing = "pricing";
}
public static class FeatureVariables
{
public const string Discount = "discount";
}
var isEnabled = _optimizely.IsFeatureEnabled(FeatureKeys.NewCheckout, userId);
var discount = _optimizely.GetFeatureVariableDouble(
FeatureKeys.Pricing,
FeatureVariables.Discount,
userId);
3. Event Tracking Configuration
EXP-003: Experimentation Tracking Not Configured (Info)
Check for event tracking setup:
Grep: Track\s*\(
Grep: IEventDispatcher
Grep: EventDispatcher
Good Pattern:
// Track conversion events
_optimizely.Track("purchase_completed", userId, new UserAttributes
{
{ "device", "mobile" },
{ "customer_type", "returning" }
});
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-experimentation is an agent published in the GitHub repository smithdak/claude-marketplace (3 stars, last pushed 7mo ago), licensed MIT. It adds 18 tokens to every session and 1,594 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.
Other agents, from other repositories
reviewer
Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
atomic-auditor
Final gate for a finished implementation. Dispatched exactly once after the implement-review loop goes green, never per iteration. Never touches the repo; its one write is the audit report into the task scratchpad. Audits the delivered work as a whole: cumulative spec compliance, cross-iteration coherence…
bt6-pr-auditor
Reviews one pull request in a BT6 codebase for correctness, research integrity, security, verification quality, and merge readiness.
Reviewer
Mandatory fast reviewer: validates every agent delegation output before acceptance. Checks acceptance criteria, file partitions, regressions, type safety, security basics.
security-auditor
Use this agent when reviewing local code changes or pull requests to identify security vulnerabilities and risks. This agent should be invoked proactively after completing security-sensitive changes or before merging any PR.
dotnet-architecture-reviewer
Reviews a .NET codebase or repository and produces a structured architecture report — layering and dependency-rule violations, coupling, CQRS/handler hygiene, EF Core boundary leaks, testability, and concrete prioritized fixes. Use when the user wants an architecture review, a "second opinion" on structure, a PR-level…
