A routing guide for broad C# and .NET work. It first identifies the application type and tools, then directs the task to a more specific .NET skill such as web APIs, cloud services, databases, or desktop apps.

It helps identify target frameworks, project SDKs, hosting models, test tools, and the narrowest matching .NET development skill.

It prevents broad .NET tasks from being handled at the wrong level and helps choose the relevant framework or platform before code is changed.

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	$0.00044	$0.00991
Opus 5.5	$0.00018	$0.00396
Sonnet 5.5	$0.00009	$0.00198
Haiku 4.5	$0.00004	$0.00099

Security

Grade A, and why

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 19d 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.

.NET Router Skill

Trigger On

the user asks for general .NET help without naming a narrower framework or tool
implementing, debugging, reviewing, or refactoring C# or .NET code in a repo with multiple app models or frameworks
deciding which .NET skill should own a task before editing code
tasks that combine platform work with testing, quality, architecture, setup, or migration decisions

Workflow

Detect the real stack first:
- target frameworks and SDK version
- LangVersion
- project SDKs and workload hints
- hosting model and app entry points
- test framework and runner
- analyzers, formatters, coverage, and CI quality gates
Route to the narrowest platform skill as soon as the stack is known:
- Web: aspnet-core, minimal-apis, web-api, blazor, signalr, grpc
- Cloud and hosting: aspire, azure-functions, worker-services
- Desktop and client: maui, wpf, winforms, winui
- Data and distributed: entity-framework-core, entity-framework6, orleans
- AI and agentic: semantic-kernel, microsoft-extensions-ai, microsoft-agent-framework, mlnet, mixed-reality
- Legacy: legacy-aspnet, wcf, workflow-foundation
Route cross-cutting work to the companion skill instead of keeping it inside generic .NET advice:
- project bootstrap or repo shape: project-setup, architecture
- frontend asset analysis in mixed .NET plus Node repos: eslint, stylelint, htmlhint, webhint, biome, sonarjs, metalint, chous
- code review: code-review
- language features: modern-csharp
- testing: tunit, xunit, mstest
- format, analyzers, coverage, and CI: format, code-analysis, quality-ci, coverlet, reportgenerator
- maintainability and architecture rules: complexity, netarchtest, archunitnet
If more than one specialized skill applies, prefer the one closest to the user-visible behavior first, then pull in the quality or tooling skill second.
Do not stop at this skill once a narrower match exists. This skill should classify and hand off, not become a generic dumping ground.
After code changes, validate with the repository's actual build, test, and quality workflow instead of generic .NET commands.

Changes

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.

dotnet is a skill published in the GitHub repository managedcode/Orleans.RateLimiting (30 stars, last pushed 11d ago), licensed MIT. It adds 44 tokens to every session and 991 once invoked, about $0.0002 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 2026-10-02.
