中文

Click the Effort row (second row of the official model menu) instead of the built-in level list: an Effort slider panel pops up — OFF/MAX scale ticks, Low/Medium/High/Ultracode status shown live, and after the panel closes the effort value stays color-coded on the menu row and on the model-seat trigger button.

🆕 v0.3.0 — Ported to DSH 0.1.5: client Context now comes from @deepseek-ai/cordis, per-session state is read/written via ctx.modelDirectories, and the settings section is installed via settings.installSection(); the adapter-metadata wrapper was dropped (see Universal effort provisioning). DSH ≤ 0.1.1 is no longer supported.

🔧 v0.2.5 — Fixed universal provisioning failing silently on explicit models arrays (dsh-settings path ops cannot traverse array nodes — the array is now replaced as a whole).

🔧 v0.2.4 — Fixed universal provisioning never landing when the pi-ai settings section registers late (now retries until the section is ready).

🆕 v0.2.3 — The model-seat trigger button also color-codes its effort name, persistent after the menu closes.

🔧 v0.2.2 — Fixed menu-row coloring breaking on whole-menu remounts (full-scan throttled repaint; color inferred from the effort text).

🆕 v0.2.1 — The effort value on the model menu's Effort row keeps its level color after the panel closes.

✨ v0.2.0 — Any custom third-party model/provider gets working thinking-effort control (hot-applied).

🎛️ v0.1.0 — Initial release: intercepts the official Effort menu and shows a Claude Code–style Effort slider panel.

Features

FeatureDescription
🎚️ Stepless draggingContinuous 0–100 dragging that writes reasoningEffort in real time (16 ms throttle, no request pile-up while dragging)
🎯 Snap on releaseSnaps to the nearest level on release / blur / keyboard end, with one confirmation write
🔥 WebGL fire trailThree-pass shaders (ignite → blur → composite); the fire front follows the thumb with spring damping
🏁 OFF/MAX ticksFirst/last levels always show OFF / MAX; middle levels show the API-returned name
🎨 Level statusEffort name shown in the panel header, colored/glowing per level; menu row and model-seat trigger keep the same color after closing (v0.2.3)
🌐 Universal effortThird-party models without reasoning metadata automatically get the universal 5-level scale; pi-ai models get wire-level dictionaries patched in, hot-applied (v0.2.0)

Only reasoningEffort is written — model selection is untouched. Models with no multi-level reasoning show 「当前模型不提供多档推理等级」 (no multi-level reasoning available).

Universal effort provisioning (v0.2.0, simplified in v0.3.0)

Any custom third-party model/provider gets thinking-effort control that actually works on the wire:

  • Wire-level provisioning (host, pi-ai): for llm-pi-ai models missing reasoningEfforts, the dictionary and compat wire dialect are patched in (hot-applied, no restart); pi-ai translates the level into real wire fields (reasoning_effort / thinking / OpenRouter reasoning.effort, etc.) and advertises the same declaration as the model's reasoning catalog metadata — which is what makes the official Effort row appear for a hand-declared model at all;
  • Client fallback scale: if the directory returns no reasoning metadata, the panel still opens with the universal 5-level scale;
  • Existing user declarations (reasoningEfforts: false or a custom dictionary) are always respected and never overwritten.

Why there is no adapter wrapper any more. Up to v0.2.5 the host half also wrapped each adapter's resolveModel to inject universalReasoning into models that declared no reasoning metadata. DSH 0.1.5 made llm.adapters a private field with no public accessor, so that path is impossible — and unnecessary: reasoningEfforts is the one declaration that feeds both the request wire and the model catalog. Model-level compat is only written when the route declares api: openai-completions, because pi-ai refuses a switch the model's protocol cannot read.

Supported wire dialects for custom endpoints (set effort-slider.defaultDialect or routes.<route>):

DialectWire effect

Install / Uninstall

# Install from GitHub (the committed lib/ artifacts need no local build)
dsh plugin --profile web add github:2768651338/dsh-effort-slider#main

# Or build locally and install from a checkout
pnpm install && pnpm build
dsh plugin --profile web add file:./dsh-effort-slider

After installing, restart DeepSeek Harness and press Ctrl+F5 once in the web page. The lib/ artifacts are committed, so GitHub installs need no local build.

Coming from a version pinned to an old DSH? Remove any - id: ui-effort-slider / disabled: true row from ~/.dsh/profiles/web/cordis.patch.yml, otherwise the new build stays switched off.

ActionCommand
Upgradedsh plugin --profile web update dsh-effort-slider (or re-run add), then restart DSH
Uninstalldsh plugin --profile web remove dsh-effort-slider, then remove its row from cordis.patch.yml if any

Quick Start

  1. Install the plugin, restart DSH, press Ctrl+F5.
  2. Open the model menu above the composer → click Effort → the Effort slider panel appears.
  3. Drag to choose a level; it snaps on release. After the panel closes, the effort value keeps its color on the menu row.
  4. For custom models with no thinking effort, the panel opens with the universal 5-level scale; pi-ai models get their wire dictionaries patched on the host side (hot-applied).

A [effort-slider] intercept row: ... line in DevTools Console means interception is working.

Configuration

ItemDetails
Plugin optionseffort-slider settings section (written to ~/.dsh/settings.yaml, hot-applied)
Defaultsenabled: true, defaultDialect: effort
Environment variablesNone of its own; follows DSH's DSH_HOME resolution
Sensitive itemsNone — no keys, tokens, or credentials are read or stored

  enabled: true          # provisioning master switch
  defaultDialect: effort # global default wire dialect
  routes:
    my-gateway: deepseek # per-route override

Permissions & Data

ScopeWhat it touches
Files (read)None — no user files are read or written (settings go through DSH's settings service)
NetworkNone of its own — the panel reads and writes the Model Controller's in-browser directory; the resulting session.selectModel call rides DSH's existing connection
CredentialsNever read
User dataNot read (no access to conversation content/messages/prompts; only the current session's provider/model/reasoningEffort through the shared model directory)

How It Works

HalfFileRole
Hostlib/index.jsUniversal effort provisioning: pi-ai wire patches (buildProvisionOps, idempotent, respects user declarations) + the effort-slider settings section installed via settings.installSection; listens to llm/adapters-updated / settings/updated for hot application
Browserlib/client.jsCaptures clicks on the model menu's Effort row → shows the Effort panel; reads ctx.modelDirectories.directoryFor(sessionId) and writes through directory.select({ reasoningEffort }); a MutationObserver keeps the menu-row level color alive after the panel closes

The browser half follows the official external-plugin convention: classic script + window.__ModuleLoader__.load factory; react / react-dom/client / react/jsx-runtime are platform externals; effort.module.css is hashed and inlined by lightningcss, injected as <style data-plugin> when the factory runs.

Troubleshooting

SymptomFix
No Effort row in the model menuThe model declares no reasoning metadata and host provisioning is not in effect — confirm DSH was restarted and check effort-slider.enabled in ~/.dsh/settings.yaml
Panel says 「当前模型不支持思考强度调节」Universal fallback not active — upgrade to v0.2.0+ and restart
Plugin does not load at all (row shows disabled: true)An earlier build was switched off in ~/.dsh/profiles/web/cordis.patch.yml; delete that row and restart
Dragging has no effectCheck whether the target endpoint's wire dialect matches (see the dialect table) or set defaultDialect for that route
Conflicts with other skin pluginsIf another skin that intercepts the Effort row is installed (e.g. the aurora skin of dsh-ui-web), disable its interception to avoid double panels
Version still shows old after restartfile: installs are snapshot copies — use the github: spec or re-run add before restarting
Where are the logs?Host errors: DSH startup log; client errors: browser DevTools (F12) Console ([effort-slider] prefix)

Development

pnpm test        # host unit tests + apply integration test + real-seam integration test + jsdom smoke

test/ layers, cheapest first:

FileScope
host.spec.mjsPure logic: dialect → wire mapping, provisioning patch generation, idempotency
host-apply.spec.mjsapply() against a mocked cordis context: late pi-ai section retry, compat gating on the declared protocol
host-integration.spec.mjsReal seam: real @deepseek-ai/cordis + real @deepseek-ai/dsh-settings-file provider — installSection registration, real path-op writes landing in a settings document, and the written reasoningEfforts/compat passing pi-ai's validation rules
client.smoke.mjsjsdom: bundle factory materialization, Effort-row interception, panel render, drag/snap writes through directory.select, coloring, teardown
