Sttrevens/dsh-linked-folders

@steven-wu/dsh-linked-folders

Out-of-tree dsh plugin that gives a session multi-folder workspace access — like Codex's linked folders.

• A global linked-folders list (durable, cross-session) — your "global workspace".
• Per-session temporary links the model adds/removes on the fly with link_folder / unlink_folder.

Both lists are injected into the system prompt, so the model knows which extra roots it may cd into and work across.

Install

The package declares a dsh.bundle manifest, so dsh plugin add installs it and adds it to the profile's bundle layers automatically:

dsh plugin --profile web add @steven-wu/dsh-linked-folders
# restart the web profile, then refresh the page

Use

• Composer → the 📁 button on the left of the input bar. Click it to open the panel: manage the global list (add by absolute path or Browse…, remove with ×) and see this session's temporary links.
• Model: say "link folder /path/to/foo" — the agent calls link_folder; "unlink /path/to/foo" calls unlink_folder. Session links appear in the prompt as (this session).

Workspace-picker entry (optional Tier-2 patch)

The official workspace-picker menu is inline (not a slot), so the plugin can't add to it. scripts/patch-workspace-picker.py patches the compiled dsh-client-ui-workspace bundle to add a "Link folder…" entry next to "Add workspace"; selecting it dispatches dsh:link-folder-requested, which this plugin listens for (opens the native picker and links the chosen path).

python3 scripts/patch-workspace-picker.py
# then restart dsh web

Re-run after a dsh update (idempotent; the original bundle is backed up to *.pre-linkfolder.bak).

Configuration

State lives in ~/.dsh/linked-folders.json:

{
  "global": ["/Users/you/projects/app", "/Users/you/projects/lib"],
  "sessions": { "session-abc…": ["/tmp/scratch"] }
}

Override the path with the DSH_LINKED_FOLDERS env var or the bundle row's config.path. Linked folders are canonicalized to real paths and must be existing directories.

Sandbox note

The plugin only advertises folders to the model and provides the management UI; it does not change the file sandbox. Under danger-full-access the model can read/write anywhere; under workspace-write it can read linked folders but writes are still confined to the session workspace root.

Model experience

• System prompt: a ## Linked folders section listing global + session roots.
• Tools: link_folder(path) / unlink_folder(path).
• Web Remote: the client bundle explicitly mounts the linkedFolders Remote contribution before the sidebar consumes it (required by dsh rc.6+).
• Prompt token cost: proportional to the number of linked folders (one short line each), zero when none are linked.
