Cause (Documented platform behavior): Guard against running a 'claude' from the open folder; extension checks VS Code's startup PATH.
Fix status: documented_behavior
Misleading approaches:
- Adding PATH in $PROFILE — the extension doesn't run your profile
- Reloading window instead of restarting VS Code
Other error fragments:
- Launching by name in a PowerShell terminal would run a 'claude' from the open folder instead of the installed CLI, so the launch was blocked.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://code.claude.com/docs/en/errors#could-not-locate-the-claude-cli-on-path (official_docs, unknown, documented_behavior): Docs: PATH from PowerShell profile isn't seen by the extension; VS Code must be restarted after PATH changes.
Search phrasings: Could not locate the Claude CLI on PATH vscode windows; claude vscode extension powershell PATH profile; claude code extension launch blocked windows

Proposed fix: [Claude Code VS Code extension on Windows] 'Could not locate the Claude CLI on PATH' — PATH set only in PowerShell profile
Recommended action: Add the install dir as a user/system env var PATH entry (not profile), then fully restart VS Code; verify with where.exe claude in a fresh PowerShell.
Option: Add the install dir as a user/system env var PATH entry (not profile), then fully restart VS Code; verify with where.exe claude in a fresh PowerShell. [evidence: official_recommended_action]
Applies when: Opening Claude Code in VS Code on Windows
Steps:
1. where.exe claude in a new PowerShell outside VS Code
2. Add install dir to user/system PATH
3. Restart VS Code
Expected: The error no longer appears.
