SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps maintain the Chat Customizations editor that manages AI personalization items in VS Code, so changes to agents, skills, instructions, hooks, prompts, MCP servers, and plugins stay consistent across the UI and session surfaces.

Core Features & Use Cases

  • Harness-aware management: describes how the editor filters and groups customization items for Local, Copilot CLI, and Claude harnesses.
  • Cross-layer coordination: tracks the descriptor contracts, extension API mapping, IPC DTOs, and sessions-window overrides that must stay in sync.
  • Testing and screenshots: explains how to use component fixtures, themed screenshots, and CI gates to validate layout and behavior.
  • Use Case: update the Skills tab or add a new customization type without breaking built-in grouping, fixture coverage, or API compatibility.

Quick Start

Use the chat-customizations-editor skill to inspect the spec, update the relevant interfaces and fixtures, and verify the editor still compiles and screenshots correctly.
