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.
Composer trigger reading OpenCode Zen/DeepSeek V4.1 Flash, Default
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
- The composer trigger reads
Provider/Model (plus · <effort> when the model reports a
reasoning effort).
- Hovering it shows the same text.
- 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.
