dsh-tool-highlight

A DeepSeek Harness (DSH) web plugin that adds layered syntax highlighting to bash / pwsh command output and read code output in the web GUI, using a VS Code Dark+ palette (keywords / strings / numbers / functions / comments each get their own color). It colors only what it recognizes; tables and logs stay plain.

Pure frontend rendering — it never adds or rewrites any session content and never calls the model: zero token overhead.

What you get

• read on code files → language detected from the extension (.py .js .ts .json .ps1 .sh ...), PyCharm-style token coloring
• bash / pwsh output → content heuristic: JSON gets key/string/number coloring; code-looking output gets syntax coloring; tables / logs stay plain (forced coloring on a receipt looks like a mess)
• Exit-code chip (green = success / red = non-zero exit or signal)
• Collapsible cards (toggleable): read / bash / pwsh cards collapse to a one-line header (path + status chip) by default — click the header to expand/collapse; running and failed cards auto-expand so live output and errors are never hidden. Turn the default-collapse off in Settings → Plugin settings → 工具卡片折叠 to restore the previous always-expanded rendering.

Configuration

UI: Settings → Plugin settings → 工具卡片折叠 (applies immediately, persisted to the user settings document). You can also write it directly in the profile's cordis.yml / settings.yaml:

tool-highlight:
  collapseByDefault: true

Install

# npm (recommended)
dsh plugin --profile web add dsh-tool-highlight

# GitHub source
dsh plugin --profile web add github:vollegrewar/dsh-tool-highlight

# local link (development)
dsh plugin --profile web add link:/path/to/dsh-tool-highlight

Restart dsh web and hard-refresh (Ctrl+Shift+R).

Installing from the GitHub source may ask for pnpm allowBuilds approval — add dsh-tool-highlight to the profile's pnpm-workspace.yaml allow list. The plugin has no build scripts, so the npm install never triggers this.

Coexist with dsh-better-tool-ui

This plugin only takes over the read / bash / pwsh tool cards (priority -2); dsh-better-tool-ui keeps handling write/edit diffs, status rails and everything else — they don't conflict. It also works standalone.

How it works

• Mounts on the official keyed slot tool.call.toolview, one renderer per tool name
• Language detection: read by file extension; command output by content heuristics (parseable JSON → JSON; ≥2 code-looking lines → Code; otherwise plain)
• A self-contained lightweight regex tokenizer (zero runtime dependencies), VS Code Dark+ palette, follows DSH theme tokens
