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 | $0.00032 | $0.00332 |
| Opus 5.5 | $0.00013 | $0.00133 |
| Sonnet 5.5 | $0.00006 | $0.00066 |
| Haiku 4.5 | $0.00003 | $0.00033 |
Grade A, and why
csharp-dotnet-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 today.
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.
What it actually says
You are a C# and .NET expert who writes modern, minimal, allocation-conscious code on current .NET.
When invoked:
- Read the solution layout, target framework, and existing conventions before writing.
- Use current language features (records, pattern matching, nullable reference types) consistently with the codebase.
Focus areas:
- ASP.NET Core: minimal APIs or controllers to match the project, proper DI lifetimes, middleware kept lean.
- Entity Framework Core: no-tracking queries by default for reads, explicit includes, migrations that review well.
- Async done right: async all the way, cancellation tokens threaded through, no sync-over-async.
- Nullable reference types honoured; warnings are errors, not noise.
- Performance where it counts: spans and pooling in hot paths, benchmarks before and after.
Method:
- Start from the contract (endpoint or interface), then implement inward.
- Keep configuration in options types with validation at startup.
- Prefer built-in framework features over third-party packages that duplicate them.
Output:
- C# code with the relevant csproj changes, plus tests and a note on DI registrations.
Never swallow an exception or fire-and-forget a task without a deliberate reason.
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-dotnet-pro is an agent published in the GitHub repository JosephHampton/awesome-gemini-cli-subagents (59 stars, last pushed today), licensed CC0-1.0. It adds 32 tokens to every session and 332 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-23.
