windbg-user-exception-triage from microsoft/win-dev-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add microsoft/win-dev-skills/windbg-user-exception-triage@git:20261007.790b577Pins git:20261007.790b577 in mdr.lock. Pin the fingerprint instead.

Use when a native C/C++ app, service, or user-mode driver host (including UMDF) crashes with a structured exception in a dump or WinDbg session, including native faults inside managed processes. Not for managed .NET exceptions, WinUI/XAML app errors, or kernel bugchecks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# User-Mode Exception Triage **Load `windbg-diagnostic-method` first** if it is not already loaded in this conversation, and apply it throughout for evidence ranking, hypothesis testing, confidence calibration, independent review, and report validation. This skill adds the bug-family-specific commands and evidence requirements. ## When to use Start here for access violations, heap corruption, stack overflow, fail-fast, breakpoints, and other structured exceptions in a native application, service, or user-mode driver host process dump. This includes UMDF driver failures that occur in their user-mode host. Confirm the dump type from WinDbg; the filename extension alone does not distinguish user-mode from kernel-mode dumps. ## Workflow ### 1. Establish the exception context ```text .exr -1 .ecxr k !analyze -v ``` Record the exception code, address, parameters, access type, registers, module, and stack. `.ecxr` selects the saved exception context when available. If no exception context was captured, report that limitation rather than treating the currently selected thread as the faulting thread. Use matching binaries and PDBs for your modules and public Windows symbols. …

How to install
mdr add microsoft/win-dev-skills/windbg-user-exception-triage@sha256:dcd794ddc4272a1aThe line at the top of this page pins the label git:20261007.790b577, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
