Dsh Harness Updater

dsh-harness-updater

English | [简体中文](README.zh.md)

**Agent harness updates for DeepSeek Harness.** Detects the locally installed [Claude Code](https://claude.com/product/claude-code) and [Codex CLI](https://developers.openai.com/codex/cli), compares them against the latest published versions, prompts in the DSH web UI, and — on your explicit click — runs the correct channel-specific upgrade command.

Inspired by the provider maintenance model of [T3 Code](https://github.com/pingdotgg/t3code).

What it does

1. Detects each harness on PATH (Windows .cmd/.ps1 shim aware) and probes --version with a bounded timeout.
2. Classifies the install channel from the resolved binary path: native installer, npm / pnpm / bun global, Homebrew, or manual-only.
3. Checks npm (registry.npmjs.org//latest) for the latest version with a 4 s timeout and a 1 h cache. Fully disabled via settings when offline.
4. Prompts: a persistent Updates card in DSH Settings → Plugins lists each harness with current → latest and an in-place Update button. Under DSH Native it also shows the native app's own self-update status.
5. Updates on click only — never silently. The runner serializes per channel lock, enforces a hard timeout with process-tree termination, caps captured output, then re-probes to verify and reports succeeded, unchanged, or failed.

Detected channel	Update command
Claude native (~/.local/bin/claude*)	claude update
npm global	npm install -g @latest
pnpm global	pnpm add -g @latest
bun global	bun install -g @latest
Homebrew	brew upgrade claude-code / brew upgrade --cask codex
anything else (WinGet, standalone installers)	manual: copyable hint, no one-click

The updater invokes npm with explicit arguments and lets npm run the package lifecycle required to install the CLI.
