windbg-user-ttd-reverse-debugging-triage SKILL.md skillA

windbg-user-ttd-reverse-debugging-triage from microsoft/win-dev-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add microsoft/win-dev-skills/windbg-user-ttd-reverse-debugging-triage@git:20261007.790b577

Pins git:20261007.790b577 in mdr.lock. Pin the fingerprint instead.

Use when an app, service, or user-mode driver host TTD recording is available and earlier calls, writes, or lifetimes matter. Not for kernel replay or history from a normal dump.

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

# TTD Reverse Debugging 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.

## Requirements and scope

Time Travel Debugging records a user-mode process for replay, including an
authorized application, service, or user-mode driver host process. A dump alone
contains no execution timeline. Confirm a valid recording and matching module
symbols before attempting timeline queries. It does not record kernel execution
or automatically include another process's server-side activity.

Recording can change timing, require substantial storage, and capture sensitive
memory. Obtain authorization before capture. Check the installed recorder's help
for supported target, architecture, and options. WinDbg's **Launch executable
(advanced)** / **Record with Time Travel Debugging** flow can record a named
test application without guessing a recorder command.

## Workflow

### 1. Open and index the recording

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add microsoft/win-dev-skills/windbg-user-ttd-reverse-debugging-triage@sha256:8211992ec082e251

The 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.
