What is refactor:dotnet?

A tool for restructuring ASP.NET Core and C# code, including controllers, repeated code, and older coding patterns. It applies modern C# features and common design principles.

Use it to break up oversized controllers, remove duplicate code, modernize C# code, and improve how an application is structured.

It helps make difficult-to-maintain .NET code easier to read and organize.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00093	$0.04847
Opus 5.5	$0.00037	$0.01939
Sonnet 5.5	$0.00019	$0.00969
Haiku 4.5	$0.00009	$0.00485

Security

Grade A, and why

refactor:dotnet 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 2mo 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.

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.
