DSH Subagent Model Picker
Choose a different model and reasoning effort for new subagents without changing the main conversation's model.
Independent main and subagent model pickers
- Separate Sub: picker beside the normal model picker.
- Per-conversation settings, with Inherited as the default.
- Existing subagents keep their model, including after continuation or restart.
- Immediate saves and a read-only picker on child conversations.

Quick start
Requires DSH Web 0.1.2-rc.1, Node 22.19+ in the 22.x line or 24+, and npm/pnpm on PATH. Run this on the machine where DSH runs, using its usual account and environment.
- Download the source using Code → Download ZIP, extract it to a permanent directory, and open a terminal there.
- In a Linux/macOS shell, run:
npm run setup &&
npm run check &&
dsh plugin --profile web add "link:$PWD"
- Once active work finishes, restart your existing DSH instance and refresh its Web page. Look for Sub: beside the main model picker.
Keep the extracted directory in place—the installation links to it. Use your actual Web profile name if it is not web.

Usage
Open Sub: and choose a provider, model and supported reasoning effort. Changes save immediately and affect new subagents only. Inherited keeps DSH's normal selection—usually the parent model, but explicit model/provider options from a spawning tool still apply. An explicit Sub: selection overrides those options.
Children with successfully saved bindings keep their captured model and effort across continuation and restart. Newly created descendants use the owning root conversation's latest explicit policy, or DSH's normal selection when it is Inherited. Children created before installation remain unmanaged.
Ordinary conversation forks have independent settings. Child conversation views are read-only. Save and validation failures are shown rather than silently switching managed children to another model.
Known limitation: If a new child's initial binding save fails, restarting DSH can leave that child unmanaged and using DSH's normal model choice instead. Fix storage and create a new child; see recovery guidance.
Compatibility
Tested on Linux with Node 22.22.3 / 24.19.0 and DSH 0.1.2-rc.1. All 61 automated tests pass, including a real archive roundtrip. Setup checks the qualified native libraries rather than installing another DSH/Cordis copy. macOS and Windows are not yet independently qualified.
This plugin controls standard in-process DSH subagents, not separate Codex or Claude CLI products. Cross-model vision support needs separate qualification. See architecture and limitations.
