Find evidence instead of guessing for .NET packages, platform libraries, local assemblies, APIs, dependencies, and version-to-version API changes.
Whole-assembly call-graph leverage ranking and performance triage for libraries (experimental).
Decide whether a change or upgrade is safe — API-surface diffs, behavioral diffs (allocations, exceptions), feature switches, and version resolution.
Judge whether code is sound and safe to call — its exception surface (throws, catches, exception types) and the unsafe operations in a method body.
Reconstruct a method or type locally as C# and IL — decompiled source, annotated source with hidden facts, raw IL, fidelity levels, and IL-offset lookup. Always local, no network.
Use for opt-in Deep Inspect run triage: test lane failures, census artifacts, pinned-subset drift, and routing findings into issues or tracker updates.
Run and interpret opt-in expensive validation lanes: full slow tests, IL round-trip sweep, corpus sensors, validity scans, and analysis census.
Map how code connects — implementors and subclasses, extension methods, dependency graphs, reverse callers, and ecosystem integrations. Many outputs are graph-shaped (add --mermaid).
