dsh-session-folder: right-click a Session row for its menu, right-click a file name to open / reveal / copy path

[cannebergeee]

A small, build-free DSH bundle I use daily: dsh-session-folder — right-click shortcuts between the Harness UI and local paths.

What it does

Session row → open the project folder. Right-click any Session row (or use the row's … as before) and the Session's own menu opens; it now carries Open in File Explorer, placed after Archive session. Right-click just activates the row's existing menu trigger, so the menu never drifts from the shipped actions (pin / rename / fork / archive / copy ID are all still there).

File name → context menu. Right-click a file name in the conversation (an assistant file chip or a Markdown file link):

Row	Behavior
Open	Open the file with the OS default application
File Explorer	Reveal the file in the file manager
VS Code	Open the file in VS Code — shown only when the desktop registers VS Code for that file type
Copy absolute path	Copy the absolute path
Copy relative path	Copy the path relative to the project folder

Why it stays thin

• Session folder = SessionSummary.cwd read at click time — no Session retained, no history loaded.
• Open / reveal / VS Code all go through the host's session.openWorkspacePath Remote, which verifies the path through the composed filesystem before handing it to the desktop.
• The VS Code row comes from session.workspacePathApplications (the desktop's registered handlers for that file), so it never offers an application the host cannot launch.
• The file path rides the chat primitive's title attribute (producedFileMentions returns { title: path }; file links do the same).
• Styling uses only the host's own menu/toast tokens (--dsw-menu-surface-fill, --dsw-menu-backdrop-filter, --dsw-elevation-prominent, --dsw-alias-toast-bg, --dsw-shadow-lv3 …), so light and dark both follow the app.

Install

dsh plugin --profile <profile> add github:cannebergeee/dsh-session-folder
# then add "@dsh-external/dsh-session-folder" to that profile's dsh.profile.bundles and restart

No build step — the runnable client.js / index.js are committed. A packed .tgz is attached to the v1.3.1 release if you prefer not to depend on git.

• Repo: https://github.com/cannebergeee/dsh-session-folder (BSD-3-Clause, topic dsh-plugin)
• Requires the DSH 0.2.1-rc line and a deployment that can hand paths to a local desktop (DSH Desktop or a locally run Web build).

Known limits are documented in the README: the Session menu opens at the … anchor rather than the cursor, and the file path source is a chat-primitive implementation detail (the Session menu row is unaffected if it ever changes).

Feedback very welcome — happy to adjust the UX or split it into separate plugins if either half would be more useful on its own.
