dsh-model-show

A DSH client plugin for the Web UI: the composer's model selector shows Provider/Model instead of a bare model name, so a selected model always names the provider it comes from.

	Composer trigger
Before	Example Chat · High
After	Example Provider/Example Chat · High

The dropdown menu is untouched: rows stay plain (Example Chat) under their provider headings, and search keeps matching plain model names. The hover tooltip and ARIA label carry the same Provider/Model text as the visible trigger.

A real trigger: provider OpenCode Zen, model DeepSeek V4.1 Flash; the trailing Default is the thinking-effort suffix DSH already appends.

Requirements

• DSH >= 0.2.0-rc.1 < 0.3.0-0, web client platform (developed and tested against the Desktop runtime 0.2.0-rc.2).
• The built-in model selection plugin (@deepseek-ai/dsh-client-ui-model-selection) must stay enabled. This plugin reuses its modelDirectories service and only shadows the composer seat.
• Provider names are whatever your own model configuration declares (displayName of each provider row), e.g. Example Provider, Example Vendor.

Install

Plugin market

Open the plugin market in the target DSH app, search for the package name dsh-model-show, install it, then enable it.

Desktop CLI

The Desktop app ships its own CLI (the reserved desktop profile is managed only by it):

"%LOCALAPPDATA%\Programs\DeepSeek Harness\resources\runtime\cli\bin\dsh.cmd" plugin --profile desktop add dsh-model-show

From GitHub, or from a local checkout:

"%LOCALAPPDATA%\Programs\DeepSeek Harness\resources\runtime\cli\bin\dsh.cmd" plugin --profile desktop add github:<user>/dsh-model-show
"%LOCALAPPDATA%\Programs\DeepSeek Harness\resources\runtime\cli\bin\dsh.cmd" plugin --profile desktop add "C:\path\to\dsh-model-show"

Remove it with plugin --profile desktop remove dsh-model-show.

From a DSH session

Ask the agent to install the bundle from this directory (plugin_manager with action: install_bundle and the package directory as target).

Reload the page after installing. Replacing an already-loaded plugin with a different build needs an application restart.

Verify

1. The composer trigger reads Provider/Model (plus · <effort> when the model reports a reasoning effort).
2. Hovering it shows the same text.
3. The menu still lists plain model names under provider headings, and searching a provider name does not match models.

How it works

• lib/index.js is the plugin's (empty) node half, so the bundle can be mounted by the profile's layer stack; the browser half is discovered through dsh.client + exports["./client"].
• cordis.patch.yml inserts one row (id: model-show, name: dsh-model-show).
• lib/client.js is the built-in @deepseek-ai/dsh-client-ui-model-selection browser bundle with six documented edits (scripts/vendor-from-asar.mjs, each marked with an EDIT: comment in the generated file). The two that produce the visible change are the provider-prefixed choices[].model.name and registering the composer seat at priority: -1, which shadows the built-in seat because the lowest priority renders. The upstream inject list is left untouched (see Limitations — the seat resolves its catalog through the consuming context).
• The label is prefixed where the trigger reads it (currentChoice?.model.name), so the menu's own groups — and therefore search — stay untouched.

Development

npm test                 # offline checks: manifest, the six edits, and the label behaviour
npm run vendor           # re-extract the upstream bundle from the installed app and re-apply the edits
npm run vendor:check     # exit non-zero when the shipped bundle is not the vendored one

npm run vendor reads %LOCALAPPDATA%\Programs\DeepSeek Harness\resources\app.asar → dsh/node_modules/@deepseek-ai/dsh-client-ui-model-selection/lib/client.js, or a client bundle passed with --from <client.js> / an archive with --asar <app.asar>.

If upstream moves an anchor, vendoring fails loudly (anchor not found (<label>) — upstream bundle changed?) instead of shipping a broken bundle; review the edits against the new bundle and update the script, then re-run npm test.

Line endings are normalised to LF by .gitattributes. lib/client.js is compared byte for byte against the vendored output, so a CRLF checkout would fail both npm test and npm run vendor:check.

Path	Purpose
package.json	Bundle and client manifest (dsh.bundle.patch, dsh.client)
cordis.patch.yml	Inserts the plugin row into the profile layer stack
lib/index.js	Node half (empty apply, so the row can mount)
lib/client.js	Vendored browser bundle with the six edits
scripts/vendor-from-asar.mjs	Vendoring: extract from an installed DSH, apply and verify the edits
tests/verify-bundle.test.mjs	Offline verification of the shipped bundle
icon.svg, locale/*.json	Plugin Manager card metadata
screenshots.json, docs/composer-trigger.png	Storefront screenshot, declared in-repo so the market reads it from here

Limitations

• lib/client.js is a vendored copy of a built-in bundle, so it also requires @deepseek-ai/dsh-client-ui-primitives, @deepseek-ai/cordis, and @deepseek-ai/dsh-client-store from the browser module table (declared in dsh.client.external). A redesign of the built-in model selector in a future DSH release can break this bundle; engines.dsh, the vendoring script, and npm test are the guard rails.
• The plugin inherits the built-in control wholesale, including its stylesheet and its min(360px, 45cqw) trigger width; a long Provider/Model label is ellipsized rather than wrapped.
• The vendored bundle deliberately keeps the built-in plugin's whole service list (commandUi, locale, sessions, slots, remote, remote.session). The seat resolves its per-session catalog through the consuming context, so trimming the list to the services this plugin visibly uses throws cannot get property "remote.session" without inject on the first render after a launch; the slot registry then retires the crashing entry and the built-in seat renders instead — with no error shown anywhere. npm run vendor and npm test guard against that edit returning.
• No configuration: the format is fixed to Provider/Model.
