dsh-model-tweaks

中文 | English

A DSH (DeepSeek Harness) web plugin: adds a Model Capabilities page to Settings for managing each model's context window, max output, input modalities and reasoning levels, plus the plugin's own global preset lists.

Supports DSH 0.1.7-rc.2 and later (0.1.x).

What it does

• Location: Settings → Model Capabilities (two tabs: Model Capabilities / Presets).
• Two-level collapsible cards: click a provider card title to open the group, click a model card title to select it and expand its capability editor inside the card (click again to collapse).
• Four fields: Context Window, Max Output, Input Modalities (Text / Image only — DSH has no audio/video), Reasoning Levels (dropdown: Default / Global / named preset / Custom…).
• Draft + Apply: only the Apply inside that model's editor writes to settings.yaml under llm-pi-ai. Reset to Default is a draft action too — it still needs Apply.
• Choosing Default deletes the field (never null/0/an empty object) and hands the value back to the DSH engine.

Presets

The Presets tab manages four plugin-owned lists. Each one is a card, and every card has its own Apply at the bottom (draft mode as well):

• Stored in {DSH_HOME}/dsh-model-tweaks/presets.json; a missing or broken file falls back to the built-in defaults instead of failing.
• Restore default presets at the bottom of the page brings back the built-in lists.
• One Apply submits the whole preset document — one document is never half-saved.

Install

Installing changes the profile config under %USERPROFILE%\.dsh and requires a DSH restart (which interrupts running sessions). Confirm before installing.

Repository: https://github.com/AkotaP/dsh-model-tweaks

Install from the Plugin page: sidebar → Plugin → Add plugin, and enter the repository address https://github.com/AkotaP/dsh-model-tweaks (the same field also takes the npm package name dsh-model-tweaks, an absolute local directory, or a tarball). DSH probes the repository with git ls-remote before handing the spec to pnpm; afterwards check that the entry is enabled in the list.

One command (the equivalent):

dsh plugin --profile desktop add https://github.com/AkotaP/dsh-model-tweaks
# once published to npm: dsh plugin --profile desktop add dsh-model-tweaks

Let an agent install it (paste this into an agent running in DSH):

Install this repository into the current DSH desktop profile: https://github.com/AkotaP/dsh-model-tweaks. Use Add plugin on the sidebar's Plugin page, or dsh plugin --profile desktop add https://github.com/AkotaP/dsh-model-tweaks. Then confirm the profile's dsh.profile.bundles lists dsh-model-tweaks, ask me first before restarting DSH, and after the restart verify that the Model Capabilities tab appears in Settings.

Restart DSH afterwards and the Model Capabilities tab appears in Settings. To uninstall: remove it from the Plugin page, or run dsh plugin --profile desktop remove dsh-model-tweaks (and make sure dsh.profile.bundles no longer lists it).

⚠️ The first save materializes that provider's whole models array into the user layer of settings.yaml (existing DSH behaviour — the official Models page does the same), which then shadows the same provider's list in cordis.patch.yml. To recover, delete the entire llm-pi-ai.providers.<provider>.models key from settings.yaml.

Test

node --test        # same as pnpm test; run from the repository root

Fully offline — no DSH and no browser. test/support/harness.mjs loads the built artifacts lib/index.js / lib/client.js through a stub module graph and a minimal React.
