XDP-for-Windows test execution and debugging workflow. Use when running tests (functional, spinxsk, pktfuzz, ringperf, rxfilter, xskmaprx, xskfwdkm), debugging bugchecks, attaching kd, recovering test machines after crashes, or invoking any tools/*.ps1 script that runs on hardware. Covers PowerShell remoting via -ComputerName, kd remote pipe debugging, and the inject/build/bugcheck/.reboot/check-drivers recovery loop.
Multi-dimensional review of a PR or feature branch in the microsoft/winappcli repo. Activate when a contributor asks to "review my PR", "review my changes", "vet my branch before pushing", "do a full review", "PR review", "review this feature", or similar. Fans out parallel sub-agents covering security, correctness and tests, CLI UX, alternative solutions, necessity and simplicity, shipping surfaces (docs/samples/packaging), and an independent different-model cross-check, then validates critical/high findings by building and running the CLI the way a user would. Applies a mandatory gut check t
Install and verify the prerequisites the win-dev-skills WinUI 3 toolchain depends on — .NET SDK 8.0.100+, WinApp CLI 0.6+, and Developer Mode. Use only when the user explicitly asks to set up or repair the toolchain. Do not invoke automatically when another skill reports a missing prerequisite; tell the user what is missing and ask them to invoke this skill.
Code quality review for WinUI 3 apps — MVVM compliance, x:Bind correctness, accessibility, theming, security, and performance. Use before committing to catch issues that the compiler and UI tests won't find.
Multi-dimensional review of a PR or feature branch in microsoft/win-dev-skills. Activate on "review my PR / changes / branch", "vet before pushing", "PR review", "is this ready to merge". Fans out parallel sub-agents over skill content, the skill-vs-tool boundary (solution hierarchy), tool correctness, payload/provenance/tests, docs & manifest sync, plus a multi-model cross-check. Reports findings to stdout. Does NOT apply fixes.
Run before every commit or push: formatting, linting, tests, dependency audits, builds, and docs.
Create a runnable WebUI example with app structure, theme wiring, Playwright tests, demo metadata, and demo-shell registration.
Framework code review checklist - correctness, performance, concurrency, design, and style.
**PROFILE TEST** - A skill for testing the profile command. USE FOR: testing profile analysis, verifying structural metrics. DO NOT USE FOR: production use.
Build, test, and validate changes in the vstest repository. Use when building vstest projects, running unit tests, smoke tests, or acceptance tests, or when deploying locally built vstest.console for manual testing.
Parse and analyze Visual Studio TRX test result files. Use when asked about slow tests, test durations, test frequency, flaky tests, failure analysis, or test execution patterns from TRX files.
Perform a code review of the current session's changes. Use when the user requests a code review via the Run Code Review button in the Changes toolbar.
Update the committed blocks-ci screenshot hashes after the "Screenshots & Tests" check fails, or investigate a screenshot diff reported on a PR. Use when asked to update, accept, or refresh component screenshot baselines from CI. This skill should be run as a subagent.
Use when running unit tests in the VS Code repo. Covers the runTests tool, scripts/test.sh (macOS/Linux) and scripts/test.bat (Windows), and their supported arguments for filtering, globbing, and debugging tests.
Use when running VS Code smoke tests or working on smoke-test CI steps. Covers npm run smoketest / smoketest-no-compile, grep filtering tests, and a temporary repeat-loop technique for tracking down flaky smoke tests in CI.
Audit code for memory leaks and disposable issues. Use when reviewing event listeners, DOM handlers, lifecycle callbacks, or fixing leak reports. Covers addDisposableListener, Event.once, MutableDisposable, DisposableStore, and onWillDispose patterns.
Use when running integration tests in the VS Code repo. Covers scripts/test-integration.sh (macOS/Linux) and scripts/test-integration.bat (Windows), their supported arguments for filtering, and the difference between node.js integration tests and extension host tests.
Analyze V8 heap snapshots to investigate memory leaks and retention issues. Use when given .heapsnapshot files, asked to compare before/after snapshots, asked to find what retains objects, or investigating why objects survive GC. Provides snapshot parsing, comparison, retainer-path helpers, and scratchpad scripts.
Diagnose intermittent VS Code Electron smoke-test failures from the Azure DevOps Flaky Smoke Tests pipeline (definition 700). Covers finding failed iterations, downloading task logs and platform artifacts with Azure CLI, correlating cumulative runner logs, tracing the introducing commit, and queueing focused validation runs.
Debug runtime-dependent bugs by generating competing hypotheses, adding temporary structured-log probes, collecting local evidence, and applying only an evidence-backed fix. Use for intermittent or timing-sensitive bugs, races, frontend/backend interaction failures, runtime-state issues, repeated speculative-fix failures, or explicit requests to instrument and collect evidence. Not for breakpoints, stepping, or variable inspection.
Set up and integrate the Component Explorer into a Vite based project. USE FOR: "set up component explorer", "add component explorer to a Vite app", "install component explorer packages", "configure the component explorer Vite plugin". DO NOT USE FOR: "write a fixture for a component", "set up a different test framework".
Run smoke tests to verify extension functionality in a real VS Code environment. Use this when checking if basic features work after changes.
