This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

dsh-chat-width

> 简体中文: README.zh.md

A small DSH (DeepSeek Harness) Web GUI plugin that makes the chat content column adapt to the screen resolution — when both side panels are collapsed, the middle area no longer stays stuck at the fixed 748px.

What it does

The DSH chat content column is hard-coded to 748px (--dsh-chat-content-width: 748px), so the middle area stays narrow with large empty margins even after both side panels are collapsed. This plugin injects CSS that overrides the width to min(100%, adaptive cap):

  • Side panels open → the content column fills the center column exactly;
  • Both collapsed → the column grows with the current screen/window resolution, up to the cap;
  • Historical user message bubbles follow the same width (overrides the fixed 525px cap);
  • The stats row below the input box (the live-stats TPS merge row) follows it too (overrides the fixed 620px cap).

Install

Method 1 — recommended, one command (restart dsh web afterwards):

dsh plugin --profile web add https://github.com/AnakinCao/dsh-chat-width.git

Method 2 — no restart (manual mount): append to ~/.dsh/profiles/web/cordis.patch.yml:

- insert:
    - id: dsh-chat-width
      name: 'dsh-chat-width'

and place the repository content under ~/.dsh/profiles/web/node_modules/dsh-chat-width/ (or pnpm add), then refresh the page once.

> Pick ONE method — never mount twice.

Adaptive rule (default)

max width = min(100%, clamp(900px, 72vw, 2560px))
ViewportContent width
1366×768≈983px
1920×1080≈1382px
2560×1440≈1843px
3840×21602560px (cap)

Tracks window size changes live — no refresh needed.

Tuning

Edit the three constants at the top of lib/client.js — changes hot-apply via DSH client HMR (~0.5s), no restart / no refresh:

  • ADAPTIVE_RATIO (default 0.72) — fraction of the viewport width
  • MIN_WIDTH (default "900px") — lower bound
  • MAX_CAP (default "2560px") — upper bound (raise it for 4K+)

Or force a fixed width from the browser console (takes effect after refresh):

localStorage.setItem('dsh-chat-width.max', '1920px')  // fixed 1920px
localStorage.removeItem('dsh-chat-width.max')          // back to adaptive

A console log line prints the active viewport and width rule on page load.

Uninstall

  • Installed via method 1: dsh plugin --profile web remove dsh-chat-width, then restart dsh web;
  • Installed via method 2: remove the insert entry from the profile cordis.patch.yml and delete ~/.dsh/profiles/web/node_modules/dsh-chat-width/, then refresh the page.

Compatibility

  • Requires the DSH 0.1.0-rc.6 web profile client plugin system (dsh web, window.__ModuleLoader__ bundle format).
  • Selectors target the conversation root's stable [data-phase] attribute with doubled specificity, so the override keeps working after the conversation package updates (hashed class names change).
  • The host half (lib/index.js) is a no-op placeholder so the loader entry mounts.
