ZZJQ678/dsh-model-picker

A collapsible, provider-grouped model picker for DSH.

Scope: tested only on DSH Desktop (whose profile is named web). The web build of DSH has not been tested and is not guaranteed to work.

Origin: this plugin — code, tests and docs — was written entirely by DSH's deepseek-4.1-flash model.

It replaces the native model picker at the bottom-right of the chat input with a list grouped by provider: collapsible per group, searchable, and carrying each model's own reasoning-effort options as declared in settings.

Features

• Grouped by provider, with the model count on each group header
• Collapsible: only the group holding the current model starts expanded
• Merges mirror providers: (modlens vision) style vision-bridge mirrors are folded back into their upstream provider, so no provider is listed twice
• Two vision badges, both inherited from settings:
  • "Vision" — the model declares image input in settings
  • "Vision bridge" — the model declares no vision, but a bridge covers it
  • Mutually exclusive; neither is shown when settings declare nothing
• Search over provider name/ID and model name/ID, auto-expanding matches
• Per-model reasoning effort, inherited from settings; switching models carries that model's default effort
• Failures are visible: when the provider catalog cannot be loaded, the reason is shown with a retry button

Install

dsh plugin --profile web add "github:ZZJQ678/dsh-model-picker"

Then restart DSH Desktop (or use "Restart Harness" in the app). The patch layer hot-reloads, but the bundle list is fixed at startup — adding a bundle only enters the front-end boot graph after a restart; pressing F5 is not enough.

The desktop profile is named web (not desktop); its directory is %APPDATA%\dsh-desktop\harness\profiles\web.

Uninstall

dsh plugin --profile web remove dsh-model-picker

The native model picker returns automatically.

Design notes

• View only, never data: the catalog, selection and reasoning effort all reuse the official ctx.modelDirectories service, so this plugin shares one session-level catalog with the native picker and modifies no provider plugin.
• Never disabled while loading: only the locked state disables the trigger, matching the native picker.
• Throws instead of rendering a dead shell: registered at priority: -1 over the native entry, so a failure abdicates the slot and the native picker takes over.
• Official component library (@deepseek-ai/dsh-client-ui-primitives) and DSH CSS variables, so it follows light/dark themes.

See README.md (Chinese) for the full engineering notes, including the real-browser pitfalls that shaped this implementation.
