Features

Features are organized as a registry (src/client/features.ts) — adding a UI tweak = one registry entry + two locale keys, and the settings page grows a switch automatically (see [Adding a feature](#adding-a-ui-feature)).

Install

# From GitHub (recommended, once published)
dsh plugin --profile web add https://github.com/haiyoucuv/dsh-chat-tweaks/archive/refs/tags/v0.1.0.tar.gz

# Or from a local directory (development)
dsh plugin --profile web add link:/path/to/dsh-chat-tweaks

> You can also install it with pnpm directly in the profile directory: > > ``bash > cd ~/.dsh/profiles/web && pnpm add /path/to/dsh-chat-tweaks > ``

> ⚠️ The old dsh-model-provider-label plugin is deprecated: its "show provider name" feature has been merged into this plugin. If you installed the old version, remove it first — both shadow the single conversation.input.model slot at priority -100, and coexistence throws: > > ``bash > dsh plugin --profile web remove dsh-model-provider-label > `` > > Guide and historical releases of the old plugin: <https://github.com/haiyoucuv/dsh-model-provider-label>

Restart dsh web (Ctrl+C, then run dsh web again) so the browser client loads the plugin bundle.

Expose the settings namespace (required, once)

> ⚠️ Known limitation of this DSH version: browser-visible settings namespaces are gated by a hardcoded allowlist (WEB_SETTINGS_NAMESPACES) in dsh-host-apiproxy. Without this step the switches render disabled and writes fail (error settings-not-exposed).

Run the idempotent patch script shipped with the plugin (re-run after a profile reinstall or a dsh upgrade):

npm run expose   # same as: node scripts/patch-apiproxy.mjs

Then restart dsh web again. The switches now read/write normally and values persist in ~/.dsh/settings.yaml.

Usage

Open Settings → Chat Tweaks and toggle:

• Show provider name — provider prefix on the model seat;
• Remove content max-width — full-width message column.

All changes apply immediately; no restart needed.

Development

pnpm install          # installs esbuild / typescript dev deps
npm run build         # builds lib/index.js (node half) + lib/client.js (browser half)
npm run typecheck     # TypeScript type check

lib/ is generated by scripts/build.mjs and committed; rebuild after editing src/ (a page refresh is enough, no server restart).

How it works

• Node half (src/index.ts): registers the dsh-chat-tweaks settings namespace (defaults on); values persist to ~/.dsh/settings.yaml.
• Browser half (src/client/):

- subscribes to the settings via ctx.settingsScope.bind; features carrying an apply run their side effect live; - registers a dedicated Settings tab (settings.section) "Chat Tweaks" (nav label + page, alongside Models / Plugins / Agent Presets / File Mentions), with one switch per FEATURES registry entry; - shadows the conversation.input.model seat at priority -100; the provider-name switch drives the trigger reactively (data reuses the host modelDirectories service, so behavior matches the stock implementation).

The full-width CSS targets the stable [data-chat-flow] attribute (hash-independent) and overrides the stock rule with !important; the switch injects/removes a <style> tag live.

Adding a UI feature

1. Add one entry to FEATURES in src/client/features.ts: { key, labelKey, descKey, default, apply? } - apply(enabled) — side effect when the switch flips (inject/remove CSS or DOM); - render features (e.g. provider name) don't need apply; components read the settings scope reactively. 2. Add the label / desc locale keys to zh / en in src/client/index.tsx. 3. Add the matching field to the schema in src/index.ts (default must match the registry). 4. npm run build, refresh — the settings page grows a switch automatically.
