dotnet-diag

Overview

Use this skill for .NET diagnostics, performance investigations, runtime debugging, memory analysis, tracing, and incident response workflows from dotnet/skills.

Workflow

1. Capture the symptom, runtime version, hosting model, traffic pattern, and recent changes.
2. Prefer concrete evidence: logs, traces, dumps, metrics, profiler output, and reproducible commands.
3. Separate observation, hypothesis, experiment, and conclusion.
4. Recommend the smallest corrective change and the validation signal that proves it.

Guardrails

• Do not claim root cause without evidence.
• Avoid introducing diagnostics that leak secrets or user data.
• Treat production incident commands as high impact and call out safety considerations.

Expected Output

Return an evidence-led diagnosis, remediation path, and verification plan for the .NET issue.
