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 | $0.00051 | $0.02114 |
| Opus 5 | $0.00026 | $0.01057 |
| Sonnet 5 | $0.00010 | $0.00423 |
| Haiku 4.5 | $0.00005 | $0.00211 |
Grade A, and why
akka-net-testing-patterns 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.
This is a copy
100% identical to akka-net-testing-patterns — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Akka.NET Testing Patterns
When to Use This Skill
Use this skill when:
- Writing unit tests for Akka.NET actors
- Testing persistent actors with event sourcing
- Verifying actor interactions and message flows
- Testing actor supervision and lifecycle
- Mocking external dependencies in actor tests
- Testing cluster sharding behavior locally
- Verifying actor state recovery and persistence

Choosing Your Testing Approach
Use Akka.Hosting.TestKit (Recommended for 95% of Use Cases)
When:
- Building modern .NET applications with
Microsoft.Extensions.DependencyInjection - Using Akka.Hosting for actor configuration in production
- Need to inject services into actors (
IOptions,DbContext,ILogger, HTTP clients, etc.) - Testing applications that use ASP.NET Core, Worker Services, or .NET Aspire
- Working with modern Akka.NET projects (Akka.NET v1.5+)
Advantages:
- Native dependency injection support - override services with fakes in tests
- Configuration parity with production (same extension methods work in tests)
- Clean separation between actor logic and infrastructure
- Type-safe actor registry for retrieving actors
Use Traditional Akka.TestKit
When:
- Contributing to Akka.NET core library development
- Working in environments without
Microsoft.Extensions(console apps, legacy systems) - Legacy codebases using manual
Propscreation without DI
See anti-patterns-and-reference.md for traditional TestKit patterns.
Core Principles (Akka.Hosting.TestKit)
- Inherit from
Akka.Hosting.TestKit.TestKit- This is a framework base class, not a user-defined one - Override
ConfigureServices()- Replace real services with fakes/mocks - Override
ConfigureAkka()- Configure actors using the same extension methods as production - Use
ActorRegistry- Type-safe retrieval of actor references - Composition over Inheritance - Fake services as fields, not base classes
- No Custom Base Classes - Use method overrides, not inheritance hierarchies
- Test One Actor at a Time - Use TestProbes for dependencies
- Match Production Patterns - Same extension methods, different

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.

akka-net-testing-patterns is a skill published in the GitHub repository ComeOnOliver/skillshub (63 stars, last pushed 2mo ago), licensed MIT. It adds 51 tokens to every session and 2,114 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to akka-net-testing-patterns, differing in 1 line, and is treated as a copy.
