The Plannotator VS Code extension redirects review sessions opened from an integrated terminal into VS Code tabs. It works alongside your coding-agent setup.
Install
Install Plannotator from the VS Code Marketplace or Open VSX. Use Open VSX for VSCodium and editors that install extensions from that registry. VS Code 1.85.0 or later is required.
Install and configure Plannotator for your coding agent, then open a new VS Code integrated terminal. Terminals created before the extension activates do not receive the browser-routing environment variable.
Use it
Launch a plan, document, or code review from the integrated terminal. The extension opens the local Plannotator URL in a VS Code tab instead of an external browser.
The extension also provides:
- Plannotator: Open URL to open a local Plannotator URL manually
- Plannotator: Add Annotation to add the current editor selection to the active review
Cmd+Shift+. on macOS or Ctrl+Shift+. on Windows and Linux as the default keybinding for adding an editor annotation
Plannotator follows the current VS Code color theme. Review panels close after you approve or submit feedback.
Remove the extension
Choose one removal method:
- In VS Code, run:
Add --profile "<profile-name>" for a named profile.
2. Open the Extensions view, find Plannotator, open its settings menu, and select Uninstall.
Use the Extensions view in VSCodium or another Open VSX editor. VSCodium uses Open VSX in that view by default. Restart the editor’s extension host when prompted.
The extension stores its virtual Plannotator cookie jar in editor-managed globalState under the key plannotator-cookies. It does not provide a command to clear that record, so the record can remain after uninstall.
Do not delete the editor’s shared profile or state database. These stores contain data from other extensions.
If the external browser still opens
- Confirm
plannotatorWebview.injectBrowser is enabled.
- Open a new integrated terminal.
- Launch the agent from that terminal and start the review again.
