dsh-t3-model-picker
A model picker for the DeepSeek Harness composer,
ported from T3 Code's model selector.
The picker: provider rail, grouped search, favorites and jump shortcuts
Open the picker, search across every provider, star what you use, and reach the
first nine rows with Cmd/Ctrl+1…9.
Credit
The selector this plugin implements is T3 Code's ProviderModelPicker. The
provider rail, the borderless search field, the row layout with a provider
footer, the favorites model, the tiered search ranking, and the Cmd+1…9
jump chords are all theirs. T3 Code is
open source under MIT;
this port keeps the same behaviour and swaps the data underneath for DeepSeek
Harness's model directory. Please support the original project.
Features
- Provider rail. A 44px column with
Favorites first and one tile per
advertised provider. The active entry carries a primary-colored indicator.
- Search. The field takes focus when the picker opens. Matching uses tiered
scoring over the model name, its description, the provider id and the
provider name, including subsequence matching for queries of three characters
or more, with a small boost for favorites. Results are grouped under provider
headings.
- Favorites. A star on every row, stored in the browser under
dsh.t3-model-picker.favorites.v1 as [{ provider, model }]. The Favorites
rail entry lists them grouped by provider.
- Jump shortcuts.
Cmd+1…9 on macOS, Ctrl+1…9 elsewhere, select
the first nine rows of the visible list; each of those rows shows its chord in
a kbd chip. The listener is live only while the card is open.
- Unavailable models. Providers the host does not report as routable are
marked on their rows, on the rail tile's tooltip, and on the trigger.
- Reasoning effort. A footer row opens the effort levels the current model
advertises. It is hidden when the model exposes none.
Install
From this repository:
dsh plugin --profile web add github:yusufameri/dsh-t3-model-picker
Or from the release tarball, which needs no build step:
dsh plugin --profile web add https://github.com/yusufameri/dsh-t3-model-picker/releases/latest/download/dsh-t3-model-picker.tgz
Once the package is on npm, the registry form is one word shorter:
dsh plugin --profile web add dsh-t3-model-picker
Any of them reconciles the profile's bundle list, so the next boot merges the
plugin's patch and loads its client half. Removing the bundle restores the
shipped model selector with no residue.

How it works
The composer's conversation.input.model seat is a single slot. Two
occupants can coexist there at different priorities, and the lowest live
priority renders, so this plugin registers at -1 and the shipped
ModelSelect at its default 0 stops rendering.
Both read the same per-session model directory (ctx.modelDirectories), which
is also what the /model command popup uses. A model chosen here is what those
surfaces show next, and a selection made there is what this picker highlights.
| File | Role |
|---|
package.json | Bundle manifest: dsh.bundle.patch plus the dsh.client web half |
cordis.patch.yml | One insert row mounting the bundle |
index.js | Host half — empty; the feature is entirely browser-side |
client.js | Client half: the picker, its styles, favorites and shortcuts |
Differences from T3 Code
Three deliberate departures, all recorded in client.js:
- Search results are grouped under provider headings. T3 renders one flat
ranked list with the provider named on each row.
- A footer row keeps the reasoning-effort selector reachable. T3 keeps effort
in a sibling control, while in DeepSeek Harness this seat is the composer's
only effort control.
- The row of the model in use carries a check mark. This seat is single-select
and the trigger is not always in view.
Known limits
- The picker needs a session-scoped model directory. Addressed subagent
sessions expose none, so the seat stays absent there.
- Jump chords are open-only, as in T3. There is no closed-picker shortcut.
- The effort footer only ever shows models whose provider advertises reasoning
metadata.
Development
No build step: client.js is plain JavaScript in the format the client module
loader takes. Edit it and reload the page.
scripts/ holds the recording tooling used for the assets above. It drives the
running DeepSeek Harness page over the Chrome DevTools Protocol, so no browser
download is needed:
node scripts/record.mjs <run-dir> # frames + stills + timeline
node scripts/encode-gif.mjs <run-dir> <out.gif> --fps 12 --speed 1.8 --start 1.14
record.mjs expects the page to show a session whose composer carries the
picker, and it restores the browser's favorites when it finishes. The encoder
crops, resizes, and assembles the GIF with sharp; it needs no ffmpeg.
