dotnet-inspect: correctness and safety

Use this skill to judge whether code is sound and safe to call: what it can throw, how it handles errors, and where it steps outside safe, managed execution. This is single-version analysis; for how these signals change between versions, use the compatibility skill.

dnx dotnet-inspect -y -- <command>

What can it throw? (exception surface)

There is no dedicated "Exceptions" section; exception behavior comes from method-body analysis. Exception Regions shows the exact catch/filter/finally layout; graph fields and hidden facts summarize behavior:

dnx dotnet-inspect -y -- member Type Method:1 -S "Exception Regions"
dnx dotnet-inspect -y -- member Type Method:1 -S "Call Graph" --fields "Throws,ThrowSites,ExceptionTypes,ConstructedExceptions,Catch,Finally"
dnx dotnet-inspect -y -- member Type Method:1 -S "Call Graph" --fields "Throws,Catch,Finally"
dnx dotnet-inspect -y -- member Type Method:1 -S Facts --tsv

Throws/ThrowSites count throw sites; ExceptionTypes/ConstructedExceptions name the exception types; Catch/Finally show handling. Exception Regions retains IL ranges and caught types. -S Facts (member, single method) lists the hidden facts in the body and supports --tsv.

Is it memory-safe? (unsafe operations)

dnx dotnet-inspect -y -- member Type Method:1 --library MyLib.dll -S "Unsafe Operations,IL"

-S "Unsafe Operations" shows the unsafe operations in a single method body, with IL evidence. For the library-wide safety surface (unsafe members, P/Invoke methods) and provenance/supply-chain signals, see the signals skill.

For one crash or profiler coordinate, use library --il-offset 0x06000001+0x5 for the default source-location, member, instruction, exception, callsite, and return-address context. Safety evidence is opt-in: --il-offset 0x06000001+0x5 -S "Context: Safety".

To confirm whether one definite unsafe operation appeared at an adjacent version boundary, first correlate caller-selected package cells:

dnx dotnet-inspect -y -- timeline --package MyLib@1.0.0..2.0.0 \
  -t MyType -m Method \
  --finding analysis.unsafety --at first --at last

Repeat --at for sparse probes or use --at all for an explicitly bounded dense traversal. A gap-spanning Added row locates a candidate boundary; it does not claim the exact introduction version. Confirm the adjacent pair:

dnx dotnet-inspect -y -- diff --package MyLib@1.4.0..1.5.0 \
  -t MyType -m Method \
  --finding analysis.unsafety

PairFinding.Added is the introduction proof. Present and Removed distinguish persistence from disappearance; the command compares only the two supplied endpoints.
