dsh-plugin-clinic

Plugin Clinic — read-only health checks for the installed DeepSeek Harness plugin set.

中文 · Usage · Checks

DeepSeek Harness is "everything is a plugin", which spreads stability risk across a freely-composable configuration layer — yet nothing tells you whether your installed set is healthy. dsh-plugin-clinic closes that gap: it inspects every profile under the Harness home and reports loader health, dependency integrity, version compatibility, install-script risk, duplicates, and patch integrity, with no writes and no external state.

Features

• Model tool plugin_health — the agent can diagnose its own environment in-session and turn findings into concrete fix advice.
• Web dashboard — a "体检" (Clinic) tab in Settings → Plugins, one entry per profile with severity-colored plugin cards.
• JSON reports — a stable schemaVersion: 1 contract for CI and scripts.
• 8 read-only checks — see docs/checks.md: load-health, bundle-manifest, peer-deps, runtime-compat, install-scripts, duplicate, patch-health, provenance.
• One row install — a single npm bundle patch mounts both the Host engine and the browser dashboard.

Screenshots

The Clinic dashboard inside the official Web GUI — Settings → Plugins → 体检. Per-profile plugin cards carry severity-colored status lines, expandable findings, and the summary bar counts critical/warning/info findings across every profile:

Install

# from npm (prebuilt lib/)
dsh plugin --profile web add dsh-plugin-clinic

# or straight from GitHub (sources; the prepare script builds them, pnpm asks you to
# allow the build once — see the official publish guide for the allowBuilds semantics)
dsh plugin --profile web add github:you/dsh-plugin-clinic

Restart the profile. The Settings → Plugins section gains a Clinic tab; the session gains the plugin_health tool.

Quick start

In any session on a profile where the plugin is installed:

体检一下我的插件

or call the tool directly with {"details": true} for per-finding evidence. In the Web GUI, open Settings → Plugins → 体检 to see every profile's health at a glance.

Configuration

Edit the bundle row in the profile's cordis.patch.yml:

- id: clinic
  name: 'dsh-plugin-clinic'
  config:
    profiles: []            # profile directory names to diagnose; empty = all
    enableTool: true        # register the plugin_health tool
    enableWebRoute: true    # register /clinic HTTP routes when a webServer exists
    webRoutePrefix: '/clinic'
    includeHomePatches: true

HTTP endpoints

Endpoint	Returns
GET /clinic/health	full ClinicReport
GET /clinic/health/summary	summary projection for the dashboard

Routes require a loopback Host header (DNS-rebinding defense, same spirit as the official /api fence); they are not authentication.

Architecture

One npm package, two halves. The Host half owns a pure diagnostic engine (src/engine/, no I/O, no ctx), the plugin_health tool, and the /clinic routes. The browser half registers the Clinic tab into the official settings.plugins.tab extension point and fetches the same report the tool returns. Design rationale is documented in the repository's internal working docs (not shipped with the package).

Model Experience

Request context and condition

What the model sees

One tool schema: plugin_health with profiles, severity, and details parameters. The tool is registered on ctx.tools like any model-facing tool, so its schema flows into the system-prompt assembly of every agent in a profile that loads this plugin.

Token effect

Fixed at registration: one tool schema entry per agent. The execution result is a ClinicReport JSON document whose size scales with the number of diagnosed plugins; details: false (the default) returns counts only, keeping the model-visible payload bounded regardless of how many plugins are installed.

KV Cache effect

The tool schema is part of the fixed prompt prefix and does not invalidate reuse. The execution result is a per-turn tool result, not part of any later request prefix.

Known Limitations and Deferred Work

• Diagnosis only, no fixes — v1 reports; repair is agent/user action. A dry-run fix proposal surface is planned for a later milestone.
• No npm online checks — deprecated flags and update availability are v2 (configurable
  • cached); v1 is fully offline.
• Current profile is not detectable — DSH exposes no API for the running profile name, so v1 diagnoses every profile (config can narrow the list). --profile extraction from argv is best-effort UI highlighting only, never authoritative.
• Browser-first dashboard — the Clinic tab is verified against the official Web GUI; Electron desktop shells carry fetch over an IPC bridge and are not yet validated.
• Loader-only plugins — entries not in a profile manifest have no package.json, so peer/runtime/script checks do not apply to them; only load-health and provenance do.
• No source-level security scan — that is dsh-plugin-doctor's job; optional integration of its CLI is deferred to v2.
• Report is a point-in-time snapshot — no cache, history, or subscription (intentionally; the same trade-off the official plugin inventory makes).
