CI Crash Dump Analysis

Dotnet repositories run tests on a distributed test infrastructure called Helix. When a test process crashes, Helix captures a dump file and publishes it as an artifact. This skill covers finding those artifacts, downloading them, and analyzing the dump.

When to Use

• A CI test crashed (not just failed with assertion errors)
• User wants to debug a dump from a PR or build

When Not to Use

• Test failed but didn't crash (normal assertion failure) — use ci-analysis
• User already has a dump file locally
• Build failures (no test execution occurred)
