[Skill] WinDbg — crash dump & Time Travel Debugging

[Jaylyn-Barbee]

Parent: #126

Summary

A guidance skill that teaches an agent how to debug Windows crashes with WinDbg / CDB, including Time Travel Debugging (TTD) traces and post-mortem .dmp analysis — so the agent moves through the problem with less guessing.

What the skill should teach the agent

• How to load & triage a crash dump (.dmp): find the faulting thread, read the exception record, interpret !analyze -v.
• Symbol setup (_NT_SYMBOL_PATH, symbol servers) and how to spot wrong symbols.
• Time Travel Debugging: capture a trace, navigate (!tt, step back), locate first-bad-state.
• Command cheatsheet with when-to-use notes (k, ~, lm, !teb, !peb, dx).
• When to hand off to the WinUI runtime error diagnostics skill.

Deliverables

• Skill (SKILL.md + supporting guidance files) under plugins/.
• Example walkthroughs (a native crash, a managed/WinRT crash).

Open questions

• Skill only for now; a live-debugger MCP server is a separate future item.
