[DOCS] VS Code docs are outdated for session list spark icon, plan markdown comments, and `/mcp` management dialog

Documentation Type

Incorrect/outdated documentation

Documentation Location

Section/Topic

VS Code workflow and MCP management guidance for new extension UI capabilities in v2.1.70.

Current Documentation

The page currently describes multi-conversation flow as:

Use Open in New Tab or Open in New Window from the Command Palette to start additional conversations.

It also currently states MCP setup/auth is terminal-first:

Configure them via CLI, then use them in both extension and CLI.

Some servers require authentication: run claude in the terminal, then type /mcp to authenticate.

What's Wrong or Missing?

A. Session list Spark icon behavior is missing

v2.1.70 adds an Activity Bar spark icon that lists all Claude Code sessions and opens sessions as full editors.

B. Plan markdown document view with comments is missing

v2.1.70 adds full markdown plan document view with comment support, but current docs only describe general plan review/editing.

C. MCP management dialog guidance is outdated

v2.1.70 adds a native MCP management dialog in the chat panel (/mcp) for enable/disable, reconnect, and OAuth flows, but docs still direct users to terminal-first management/authentication.

Suggested Improvement

Update the VS Code page with a dedicated section for v2.1.70 extension UX:

1. Activity Bar spark icon session list and full-editor session opening behavior.
2. Plan markdown document view and how comments are added.
3. Native MCP management dialog workflow in chat panel (/mcp) including reconnect and OAuth flows, with terminal usage as optional fallback.

Impact

Medium - Makes feature difficult to understand

| https://code.claude.com/docs/en/vs-code | 13, 149-153, 305-315 | Multi-session guidance and MCP instructions do not cover new session list, plan markdown comments, or native MCP dialog workflows |
