Token counts were measured against two well-known public NuGet packages: Newtonsoft.Json (127 public types, 1,198 members) and Microsoft.EntityFrameworkCore 8.0.10 (a significantly larger surface).

The baseline is an ILSpy-decompiled version of the package DLL — the raw C# source an AI assistant would otherwise need to load to understand the package. This is the most realistic baseline: when a developer asks an AI to help with a third-party package, the AI has no choice but to work from decompiled source or training data if no structured context is provided.

Token counts are approximated using the standard chars ÷ 4 rule of thumb, which closely matches GPT-4 and Claude tokenization for structured text.

Results: the ultra format reduced the Newtonsoft.Json context from ~466,000 tokens to ~27,000 — a 94% reduction. For EF Core, from ~2,394,000 tokens to ~621,000 — a 74% reduction. Larger packages with more repetitive structure (deep inheritance, many similar method signatures) compress more aggressively; smaller, tighter packages compress less.

Yes. There are no per-project or per-developer restrictions. Use it across as many packages, repositories, and CI environments as you like.
