Claude Code (VSCode extension) cant read virtual/on-memory Sailpoint Extension

Type: Bug

Feature request: Claude Code (VSCode extension) can't read virtual/in-memory
documents opened by other extensions — only real files on disk.

Example: the SailPoint ISC extension opens documents from a virtual filesystem
(e.g. "\v2025\sources\<hash>\[PRD] ..."). These have no file on disk, so the
Read tool can't access them, even though the file is open and active in the editor.

GitHub Copilot can read these because it uses the VSCode document API
(activeTextEditor.document.getText()).

Request: let Claude Code read the content of the active editor document via the
VSCode API, not just files on the filesystem.

VS Code version: Code 1.128.0 (fc3def6774c76082adf699d366f31a557ce5573f, 2026-07-07T15:14:24-07:00)
