Searchable model selector for DeepSeek Harness. Replaces the default model dropdown in the composer with a searchable version — no more scrolling through hundreds of models!

Features

  • 🔍 Search models — Type to filter by name, ID, or provider
  • 📦 Grouped by provider — Models organized by provider (OpenAI, Anthropic, DeepSeek, etc.)
  • ✅ Current selection — Highlights the active model with a check icon
  • ⚡ Fast — Loads models via the existing session API
  • 🎨 Theme-aware — Uses DeepSeek Harness design tokens (--dsw-*), adapts to light/dark mode
  • ♿ Accessible — Full keyboard navigation, ARIA attributes, focus management
  • 🕘 Recent models — Quickly jump back to your last-used models

Install

npm install @ardli-firman/dsh-model-search --registry=https://npm.pkg.github.com

Then link to your DSH profile:

dsh plugin --profile web add link:./node_modules/@ardli-firman/dsh-model-search

From GitHub repo

dsh plugin --profile web add github:ardli-firman/dsh-model-search-plugin

Note: pnpm ≥10 requires build permission for git dependencies. After the first add fails, add this to your profile's pnpm-workspace.yaml:

allowBuilds:
  @ardli-firman/dsh-model-search: true

Then re-run the add command.

From local checkout

git clone https://github.com/ardli-firman/dsh-model-search-plugin.git
dsh plugin --profile web add ./dsh-model-search-plugin

Then restart DeepSeek Harness:

dsh --profile web

Uninstall

dsh plugin --profile web remove @ardli-firman/dsh-model-search

How it works

The plugin replaces the conversation.input.model slot with a searchable dropdown component. It:

  1. Fetches available models from the session's model directory API
  2. Groups them by provider
  3. Provides a search input to filter models in real-time
  4. Submits selection via session.selectModel RPC

Design

The selector follows the DeepSeek Harness design system:

  • Trigger: ToggleButton chip (28px, rounded 24px) matching the official ui-model-selection
  • Menu card: 12px rounded, --dsw-specific-menu surface, --dsw-shadow-lv3 shadow
  • Option rows: 38px height, 10px radius, hover/focus surface, trailing check icon
  • Tokens: All colors use --dsw-* design tokens (auto light/dark)

Test coverage

The test suite covers:

  • Rendering: trigger button, current model name, disabled/hidden states
  • Dropdown: open/close, outside click, Escape key, load on open
  • Model list: grouped display, model IDs, check icons, loading/empty/error states
  • Search: filter by name/ID/provider, case-insensitive, no-results message
  • Selection: click to select, close on success, stay open on rejection, locked state
  • Keyboard: ArrowDown/Up navigation, Enter/Space to select, focus wrapping
  • ARIA: aria-haspopup, aria-expanded, role="menu", role="menuitemradio", aria-checked
  • Styles: --dsw-* token usage, no old --bg-*/--text-* tokens
  • Registration: slot injection, directory store lifecycle, subscriber notifications

Release

Releases are automated via GitHub Actions. To publish a new version:

# Bump version in package.json
npm version patch   # or minor / major

# Push with tags
git push && git push --tags

The CI workflow will automatically publish to GitHub Packages.
