Problem

Users could open a project in an editor or file manager, but had no way to launch a system terminal in the project folder from the Open in menu.

Change

Add Terminal as an Open in option. The server detects a usable terminal for macOS, Windows, and graphical Linux environments, then opens it in the project folder (or the containing folder for a file). File links continue to use an editor without replacing a saved Terminal preference. Document the behavior in the terminal guide.

Scope and approval

This is a focused extension of the existing Open in capability: it adds a destination alongside the editors and file manager, with no new workflow or setting.

Screenshots

Before: main has no Terminal option. See Maria's capture.

After: Terminal in the Open in menu, with Terminal as the preferred choice. These images are the app's real menu rendered to PNG in the browser, not window captures, because the preview browser's screenshot tool was timing out.

Light	Dark

Verification

vp run check:changed passed, including focused tests for terminal command resolution and launch arguments, and preserving a saved Terminal preference when opening files. In a real web app session on macOS, Terminal appeared in the Open in menu and opened a window in the project folder. Windows and Linux launch behavior was covered by mocked tests; no real-device checks were run on those platforms.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Adds a system-terminal option for opening project folders. The unresolved Windows path-quoting finding reports arbitrary PowerShell execution from specially named directories and needs resolution before this behavior is accepted.

Walkthrough

The change adds system terminal discovery and launch behavior for macOS, Windows, and Linux. The web interface offers Terminal in Open in when available and excludes it from file-opening editor choices.

Changes: System terminal support

Layer / File(s)	Summary
Terminal contract and discovery packages/contracts/src/editor.ts, apps/server/src/process/externalLauncher.ts	The editor contract adds Terminal. Server discovery checks platform-specific commands and reports Terminal as available when a command is found.
Terminal launch behavior apps/server/src/process/externalLauncher.ts, apps/server/src/process/externalLauncher.test.ts	The launcher derives a working directory from the target and starts the platform terminal with platform-specific arguments. Tests cover macOS, Linux, and Windows, including a Windows path with shell metacharacters and Unicode.
Web terminal option and editor selection apps/web/src/components/chat/OpenInPicker.tsx, apps/web/src/components/Icons.tsx, apps/web/src/editorLabels.ts, apps/web/src/editorPreferences.ts, apps/web/src/editorPreferences.test.ts, apps/web/src/fileContextMenu.ts, docs/user/terminal.md	The picker displays Terminal when available. File-opening editor selection and context menus exclude it. The documentation describes launch locations and platform selection.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Pass the directory to xdg-terminal-exec explicitly.

When xdg-terminal-exec selects a terminal that does not carry inherited process cwd into a new terminal context, args: [] can open the terminal in a different folder or focus an existing window. The utility defines --dir=... to pass the folder through a terminal-specific argument when supported. Use that option for this candidate and add a focused launch test. (github.com)

Verified in a real dev environment

verified on a linux boat vm with repository playwright and /usr/bin/google-chrome, using one background dev server at a time. created a git project through the app and completed real codex gpt-6.1-sol turns on main and this pr. no mocked app data or replay provider.

• main 8b44f42b14: open-in offered files, with no terminal option.
• original head 33d02b4978: terminal appeared, but the default terminal opened in /home/user. starting the server without display variables also hid terminal despite a recoverable desktop session.
• fixed head d59beddfcca0f72460b6b7c3397635c47aafe3cc: project launches open in the project folder; docs/note.md preview launches open in docs. checked native terminal prompts and shell working directories. also verified discovery and launch with display variables removed from the server environment.
• nearby behavior: file links still open the real preview; reveal-in-files selects note.md; file context menus exclude terminal; the terminal preference survives file actions; the integrated terminal executes pwd and cat docs/note.md in the project.

Not verified

native macos and windows launches, electron, ios/android, remote/relay/tunnel connections, and linux terminal emulators other than the default ghostty. this vm cannot prove those native paths. windows path encoding and other linux argument variants have focused automated coverage, not native-device verification.

Note

🤖 Claude Opus 5.5 responding on behalf of wSedlacek

Replying to CodeRabbit's review-body finding on xdg-terminal-exec, which has no thread of its own: fixed in d59bedd. linuxTerminalArgs now passes --dir=<directory>, and the launcher test asserts it. This is covered by that test only, because the Linux VM run used the default terminal.

Both inline findings are fixed in the same commit and answered in their threads.

Document the launch step.

In the project picker, choosing Terminal only selects it. The user must then click the adjacent Open button to launch it. Update the instructions to include that step. (raw.githubusercontent.com)
