[DOCS] VS Code integration docs missing `vscode://anthropic.claude-code/open` URI handler

Documentation Type

Missing documentation (feature not documented)

Documentation Location

Section/Topic

Programmatic opening of Claude Code tabs in VS Code via URI handler.

Current Documentation

The VS Code docs describe interactive opening methods such as:

Activity Bar: click the Spark icon ... Command Palette: ... select an option like "Open in New Tab" * Status Bar: click ✱ Claude Code ...

No URI-based launch method is documented.

What's Wrong or Missing?

Release v2.1.72 added a vscode://anthropic.claude-code/open URI handler with optional prompt and session query parameters to open Claude Code tabs programmatically.

Current VS Code docs only cover manual UI entry points, so automation and extension-integration workflows cannot discover this capability.

Suggested Improvement

Add a short "Programmatic launch" section in VS Code docs with:

1. URI format: vscode://anthropic.claude-code/open
2. Supported query parameters (prompt, session) with examples
3. Behavior notes (for example, opens a new Claude Code tab)

Impact

Medium - Makes feature difficult to understand
