MicrosoftSkillMicrosoftSkillflaky-smoke-tests
microsoft/vscode/.github/skills/flaky-smoke-tests/SKILL.md
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.
MicrosoftSkillheap-snapshot-analysis
microsoft/vscode/.github/skills/heap-snapshot-analysis/SKILL.md
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.
MicrosoftSkillintegrated-browser
microsoft/vscode/.github/skills/integrated-browser/SKILL.md
Use this when working on the VS Code integrated browser ("browserView") to understand its architecture and mental model. Covers the embedded Chromium browser, its editor tab, navigation, overlay/layout, sessions, and agent browser tools under `src/vs/platform/browserView` and `src/vs/workbench/contrib/browserView`.
MicrosoftSkillintegration-tests
microsoft/vscode/.github/skills/integration-tests/SKILL.md
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.
MicrosoftSkillissue-grouping
microsoft/vscode/.github/skills/issue-grouping/SKILL.md
Group similar issues.
MicrosoftSkillmemory-leak-audit
microsoft/vscode/.github/skills/memory-leak-audit/SKILL.md
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.
MicrosoftSkillmigrate-issues
microsoft/vscode/.github/skills/migrate-issues/SKILL.md
migrate GitHub issues from one repository to another
MicrosoftSkillotel
microsoft/vscode/.github/skills/otel/SKILL.md
OpenTelemetry guidance for VS Code agent experiences. Use when changing Agent Host telemetry, local Copilot Chat telemetry, provider-native spans or metrics, OTel settings and managed policy, trace persistence/export, or monitoring documentation.
MicrosoftSkillpolicy-and-managed-settings
microsoft/vscode/.github/skills/policy-and-managed-settings/SKILL.md
Use whenever adding, modifying, or reviewing any Copilot, agent, LLM, AI, tool, permission, sandbox, MCP, model, telemetry, feature-gate, setting, configuration, or enterprise control—especially anything an organization or administrator may need to manage. Start here to decide whether it belongs in runtime managed settings, a typed SDK contract, VS Code configuration policy, extension policy, or a split implementation. Run on every new Copilot/agent/LLM control and ANY change that adds a `policy:` field.
MicrosoftSkillsessions
microsoft/vscode/.github/skills/sessions/SKILL.md
Core principles and workflow router for changes to the Agents Window under src/vs/sessions.
MicrosoftSkillsetup-environment
microsoft/vscode/.github/skills/setup-environment/SKILL.md

MicrosoftSkillsmoke-tests
microsoft/vscode/.github/skills/smoke-tests/SKILL.md
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.
MicrosoftSkillsweeper-implement
microsoft/vscode/.github/skills/sweeper-implement/SKILL.md
Implement a VS Code Sweeper agent-ready issue — fetch the sweeper's review record from its state repo, implement the change in the current vscode checkout from the review's brief (an implement-ready record) or from an approved sweeper-plan file, validate the diff against it, and — after the maintainer has reviewed the changes in their editor — open a draft PR. Use ONLY when the request explicitly asks for the sweeper — "sweeper-implement", "sweeper", "vscodesweeper", a sweeper record, an agent-ready issue, or a sweeper brief — or asks to implement a sweeper plan ("implement plan <n>", a `.sweeper/plans/issue-<n>.md` file). Do NOT use for a plain "fix this issue" request that doesn't mention the sweeper; fix those directly with your normal tools instead.
MicrosoftSkillsweeper-plan
microsoft/vscode/.github/skills/sweeper-plan/SKILL.md
Plan a VS Code Sweeper agent-ready issue with the maintainer — fetch the sweeper's review record from its state repo, put the review's open decisions to the maintainer, and write a plan file (.sweeper/plans/issue-<n>.md) for them to edit in their editor; it writes no code and ends there — the sweeper-implement skill implements the approved plan. Use ONLY when the request explicitly asks for the sweeper plan — "sweeper-plan", "plan … with the sweeper", a sweeper record or agent-ready issue to plan first. Do NOT use for a plain planning request that doesn't mention the sweeper.
MicrosoftSkillsymbolicate-crash-dump
microsoft/vscode/.github/skills/symbolicate-crash-dump/SKILL.md
Symbolicate a native VS Code crash dump (.dmp) using electron-minidump. Use when given a crash dump file, asked to symbolicate a crash, resolve missing method names in a native crash backtrace, or attach Electron/Insiders/Stable symbol files. VS Code team members only; requires macOS or Linux.
MicrosoftSkillunit-tests
microsoft/vscode/.github/skills/unit-tests/SKILL.md
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.

MicrosoftSkillupdate-screenshots
microsoft/vscode/.github/skills/update-screenshots/SKILL.md
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.
MicrosoftSkillux-css-layout
microsoft/vscode/.github/skills/ux-css-layout/SKILL.md
VS Code CSS conventions, file organization, class naming, standard sizes, SplitView/Grid layout, scrollable content, responsive layout, and text overflow/ellipsis patterns. Use when writing CSS, building layouts, or fixing text truncation issues.
About skills
What is a Claude skill?
A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.
How do I use one I find here?
Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.
What do the warnings mean?
We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.
Which skills worked for people?
Open a skill to see its discussion. Reports from people and their agents are coming.
