DSH Claude Style Reasoning Slider

An animated reasoning-effort slider and model picker for DeepSeek Harness (DSH).
It replaces the native model selector's conversation.input.model slot with a
compatible selector whose reasoning pane is a Claude-style animated slider.

Features

• Drop-in model selector — replaces only the conversation.input.model slot;
  the rest of the chat input stays untouched.
• Canonical effort slider — always shows Off | Low | Medium | High | Extra | Max
  positions, regardless of how the provider names its levels.
• Tolerant name matching — aliases such as off, none, disabled,
  ultracode → max, med → medium, extreme → extra, and similar
  display names are mapped to canonical slider positions.
• Unsupported levels stay visible — a level the current model does not
  support is dimmed but remains clickable. Clicking it keeps the thumb on the
  chosen slot and applies the nearest supported level below it, with a toast
  explaining the downgrade.
• Model switching preserves effort — when you switch models, the current
  effort is kept when possible, or automatically downgraded to the nearest
  supported level below it (with a toast).
• Default and adapter-specific strengths — Default is offered as a pill
  below the slider and submits without reasoningEffort (the provider's own
  default applies). Other provider strengths that do not map to a canonical
  slider position are also shown as selectable pills.
• Models without reasoning metadata stay manageable — when DSH does not
  expose reasoning/efforts for the selected model (for example some
  OpenRouter or hand-declared custom entries), the Effort menu still appears:
  it shows a short “no effort levels” notice plus the safe Default pill,
  instead of hiding every thinking-strength control.
• Liang Calibrator (滑动变祖器) — optional, off by default. Binds the six
  canonical levels to stage names: Off → 小难梁, Low → 牢梁,
  Medium → 梁子, High → 梁圣, Extra → 梁神, Max → 梁祖. When enabled,
  a 31-frame portrait (frame-00…frame-30) appears above the slider and
  follows the thumb continuously while dragging, then snaps to the segment's
  first frame on release. Labels and the trigger show Max 梁祖-style suffixes.
  The setting persists in localStorage.
• Big Fat Fish thumb — optional, off by default. Replaces the slider thumb
  with an 8-frame running chibi fish sprite. The idle animation loops at
  720ms, speeds up to 420ms while dragging, and freezes under
  prefers-reduced-motion. Toggle it in DSH Settings → General → Big Fat Fish
  slider; changes apply immediately and persist in localStorage.
• High / Extra ripple field — High and Extra now show a sparse blue /
  purple dot-matrix field with random flicker and radial water ripples around
  the thumb, as a lighter prelude to the Max pixel field.
• Max / Ultracode treatment — the model's max/ultracode level turns the
  slider into an animated purple pixel field, and the Max label becomes a
  flowing multi-color gradient text.
• Localized and theme-aware — ships with English and Simplified Chinese
  dictionaries and follows DSH light/dark design tokens.
• Accessible — keyboard-operable slider (arrows, Home/End, PageUp/PageDown),
  ARIA labels, focus management, and prefers-reduced-motion support.

Install

Install the bundle from the Git repository:

dsh plugin --profile web add github:MEMZ-JZY/DSH-Claude-Style-Reasoning-Slider
dsh --profile web

Or use a local checkout:

dsh plugin --profile web add ./dsh-client-ui-effort-slider

Restart the web profile after installing or removing the bundle.

Usage

1. Click the model/effort trigger chip in the conversation input.
2. In the popup menu, choose Model to switch models, or Effort to adjust
   the reasoning level of the current model.
3. In the effort pane:
   • Drag or click the slider to pick Off, Low, Medium, High, Extra,
     or Max.
   • If a position is unsupported, the thumb stays where you clicked and the
     nearest supported level below is applied; a toast tells you what happened.
   • Click Default to remove reasoningEffort and let the provider decide.
   • Click any extra pill to apply a provider-specific strength that does not
     map to a slider position.
   • If the model has no declared reasoning levels, the pane shows a notice
     and only the Default pill. For providers that do support effort but
     are configured without reasoningEfforts (common with custom OpenRouter
     routes), add the levels in DSH's llm-pi-ai settings to get the full
     slider back.
4. When switching models, the plugin preserves the current effort level where
   supported; otherwise it downgrades to the nearest supported level below or
   falls back to Default, always with a toast.
5. To enable the Liang Calibrator, click the 滑动变祖器 switch below the
   track. The portrait and stage-name suffixes turn on immediately; the state
   is remembered across sessions.
6. To enable the Big Fat Fish thumb, open DSH Settings → General and turn
   on Big Fat Fish slider. The thumb changes immediately without a restart.

UI effects

• Trigger chip — shows the current model and effort label, six rising
  signal bars that fill with the current level, and a chevron. At Max the
  effort label flows as a purple gradient. With the Liang Calibrator enabled it
  also shows stage suffixes such as Max 梁祖.
• Two-level popup menu — a compact menu with a model list (grouped by
  provider) and an effort pane; loading/error/retry states are included.
• Glass track — inner bevel shadows and a subtle fractal-noise layer break
  up flat-color banding.
• Light field — the track responds to the pointer like a light source: an
  interior light pool and a glass-edge highlight follow the cursor, brightening
  as the pointer approaches and fading with distance. The light is suppressed
  at Max so the pixel field stays clean.
• Level labels — faint tick labels; the current level is always shown,
  hovering near a slot highlights it, and others stay barely visible.
• Liang portrait — when the Liang Calibrator is enabled, a 224px square
  portrait appears above the track. It uses 31 WebP frames (frame-00…
  frame-30) that change continuously while dragging and keep the original
  scanline + light-spot texture.
• Liang toggle indicator — the 滑动变祖器 switch below the track uses a
  dot indicator: a gray dot when off, a glowing purple dot when on.
• High / Extra dot-matrix ripple — High (blue) and Extra (purple) show a
  sparse particle field that expands from the thumb, flickers randomly, and
  animates bright/dark water ripples radiating outward.
• Max pixel field — at Max the track becomes an animated purple pixel
  field with a reveal sweep and flowing cell flicker; the Max label uses a
  flowing multi-color gradient.
• Big Fat Fish thumb — when enabled, the thumb becomes an 8-frame running
  chibi fish sprite. It loops at 720ms when idle, 420ms while dragging, and
  freezes under reduced motion. The left edge stays aligned and the right edge
  is clamped so the fish never overflows.
• Motion safety — effects use CSS transitions/animations or lightweight
  event handlers, and prefers-reduced-motion is respected.

Development

Build the client bundle from source:

npm install
npm run build

lib/client.js is generated from src/client.js plus src/ds-effort-slider.js
by scripts/build-client.mjs.

Run the standalone component demo:

# open demo/index.html in a browser

The demo page exercises panel mode, inline mode, supported-level combinations,
theme switching, the Max pixel field, the Liang Calibrator, and the Big Fat Fish
thumb.

Package contract

This is a DSH bundle, not a dynamic cordis_define snippet. The package uses:

• dsh.bundle.patch (cordis.patch.yml) for self-registration.
• dsh.client.platform: web for the browser half.
• lib/client.js as a prebuilt ModuleLoader artifact, generated from src/.
• index.js as the host half: it mounts an /effort-slider-assets/ static
  route that serves assets/liang-frames/*.webp and
  assets/chibi-runner-strip.png to the browser half.

Files

• index.js — host half; serves the Liang portrait frames and chibi sprite.
• src/ds-effort-slider.js — standalone Web Component (shadow DOM, no framework).
• src/client.js — React wrapper + forked model selector plugin logic.
• scripts/build-client.mjs — bundle generator.
• demo/index.html — standalone UI demo.
• assets/ — liang-frames/ (31 WebP frames) and chibi-runner-strip.png.
