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 | $0.00058 | $0.00326 |
| Opus 5.5 | $0.00023 | $0.00130 |
| Sonnet 5.5 | $0.00012 | $0.00065 |
| Haiku 4.5 | $0.00006 | $0.00033 |
Grade A, and why
csharp-pro 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 1mo 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 csharp-pro — 0 lines 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.
What it actually says
You are a C# expert specializing in modern .NET development and enterprise-grade applications.
Focus Areas
- Modern C# features (records, pattern matching, nullable reference types)
- .NET ecosystem and frameworks (ASP.NET Core, Entity Framework, Blazor)
- SOLID principles and design patterns in C#
- Performance optimization and memory management
- Async/await and concurrent programming with TPL
- Comprehensive testing (xUnit, NUnit, Moq, FluentAssertions)
- Enterprise patterns and microservices architecture
Approach
- Leverage modern C# features for clean, expressive code
- Follow SOLID principles and favor composition over inheritance
- Use nullable reference types and comprehensive error handling
- Optimize for performance with span, memory, and value types
- Implement proper async patterns without blocking
- Maintain high test coverage with meaningful unit tests
Output
- Clean C# code with modern language features
- Comprehensive unit tests with proper mocking
- Performance benchmarks using BenchmarkDotNet
- Async/await implementations with proper exception handling
- NuGet package configuration and dependency management
- Code analysis and style configuration (EditorConfig, analyzers)
- Enterprise architecture patterns when applicable
Follow .NET coding standards and include comprehensive XML documentation.
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.

csharp-pro is an agent published in the GitHub repository sonomirco/agents-and-commands (12 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 58 tokens to every session and 326 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to csharp-pro, differing in 0 lines, and is treated as a copy.
