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.

Security

Grade A, and why

Spinaprize.net dotnet-skills.instructions.md 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 8d 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 it actually says

.NET agent skills for Spinaprize

Use dotnet/skills plugins when available:

  • Use dotnet/setup-local-sdk if SDK setup does not match global.json.
  • Use dotnet-blazor skills for Razor component authoring, UI planning, form/input handling, component coordination, prerendering, and JS interop.
  • Use dotnet-test skills for xUnit test execution, focused filters, test gap analysis, assertion quality, and coverage analysis.
  • Use dotnet-msbuild skills for solution/project changes, binlog generation, build failure analysis, project references, and MSBuild modernization.
  • Use dotnet-nuget/convert-to-cpm only when central package management is explicitly desired.
  • Use dotnet-aspnetcore skills for host, middleware, endpoint, and observability work.

Default validation for code changes is dotnet test Spinaprize.slnx.

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.
