launch

microsoft/vscode/.agents/skills/launch/SKILL.md

Launch Code OSS (VS Code from sources) into an isolated throwaway profile with unique debug ports so you can drive it with @playwright/cli AND attach a Node debugger via dap-cli in the same session. Use when working on VS Code itself and you want to interact with the running workbench, automate chat or UI flows, test UI features, take screenshots, set breakpoints in the renderer / extension host / main process, or combine UI driving with debugging.

vscode / references

microsoft/vscode/extensions/copilot/assets/prompts/skills/agent-customization/references/agents.md

Custom personas with specific tools, instructions, and behaviors. Use for orchestrated workflows with role-based tool restrictions. Use reasoning-effort to set the reasoning level for the custom agent's model: The selected model must support the configured level. If omitted, the runtime resolves the effort from the model configuration and, when applicable, the parent agent. Sources: built-in aliases, specific tools, MCP servers (<server>/*), extension tools. Special: [] = no tools, omit = defaults. Body reference: #tool:<name> To discover available tools, check your…

agent-customization

microsoft/vscode/extensions/copilot/assets/prompts/skills/agent-customization/SKILL.md

**WORKFLOW SKILL** — Create, update, review, fix, or debug VS Code agent customization files (.instructions.md, .prompt.md, .agent.md, SKILL.md, copilot-instructions.md, AGENTS.md). USE FOR: saving coding preferences; troubleshooting why instructions/skills/agents are ignored or not invoked; configuring applyTo patterns; defining tool restrictions; creating custom agent modes or specialized workflows; packaging domain knowledge; fixing YAML frontmatter syntax. DO NOT USE FOR: general coding questions (use default agent); runtime debugging or error diagnosis; MCP server configuration (use MCP docs directly); VS Code extension development. INVOKES: file system tools (read/write customization files), ask-questions tool (interview user for requirements), subagents for codebase exploration. FOR SINGLE OPERATIONS: For quick YAML frontmatter fixes or creating a single file from a known pattern, edit the file directly — no skill needed.
