What is nuget-package-publishing?

A guide to publishing NuGet packages according to common best practices. NuGet is the package manager and package registry commonly used by .NET projects.

Use it when configuring, building, checking, or packaging a .NET library for NuGet.

It reduces mistakes in licenses, documentation, package metadata, dependencies, versioning, builds, and quality checks before publishing.

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.

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	$0.00000	$0.04599
Opus 5	$0.00000	$0.02299
Sonnet 5	$0.00000	$0.00920
Haiku 4.5	$0.00000	$0.00460

Security

Grade A, and why

nuget-package-publishing 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 5d 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.
