A DSH (DeepSeek Harness) plugin that watches your OpenCode GO plan quota — the $10/month subscription that gives you usage limits on open-source models (rolling 5-hour, weekly, and monthly windows).

Features

• Sidebar widget — a live widget pinned at the bottom of the DSH web sidebar (sidebar.footer.action slot) showing three usage bars: rolling (5h), weekly, and monthly, each with a relative countdown to its window reset. When the sidebar is collapsed it shrinks to a compact percentage badge.
• /opencode-go chat command — prints the same numbers as text inside any conversation.
• Same-origin proxy — the host registers GET /opencode-go/usage, forwards to the official GO gateway with your API key. The key never reaches the browser and no CORS is involved.

How it works

The plugin is a dual-half DSH package:

half	file	role
host (Node)	lib/index.js	registers the /opencode-go/usage web route (ctx.webServer) and the /opencode-go command (ctx.commands); resolves the key through DSH credentials; caches the upstream call (30 s)
browser	lib/client.js	a hand-authored window.__ModuleLoader__.load({ id, factory }) bundle that registers into the sidebar.footer.action list slot and polls the same-origin route every 60 s

package.json declares "dsh": { "client": { "platform": "web" } }, so DSH's client-modules node half scans it into the browser boot graph (window.__DSH_BOOT__) and serves the bundle at /plugins/dsh-opencode-go-usage/client.js.

How the sidebar widget loads under the official install

dsh plugin add installs the package into the profile, which satisfies the host half (routes, command, settings). DSH's client-modules scanner can only resolve browser bundles from its own installation directory, so a profile-installed third-party package would normally lose its browser half — this plugin avoids that by self-hosting its bundle: the host registers the /dsh-opencode-go-usage/client.js route and injects its boot-graph row through the official webServer.tapIndex API. The sidebar widget therefore works from any installation location.

Requirements

• DSH installed and the web profile booted at least once (~/.dsh/profiles/web exists)
• Node.js ≥ 18 (for fetch)
• An OpenCode GO subscription and its API key

Install (official DSH flow)

Requirements: DSH installed with the web profile booted once, Node.js ≥ 18, an OpenCode GO subscription.

# 1. install the package into your web profile (pnpm; enable via corepack if needed)
dsh plugin --profile web add dsh-opencode-go-usage

# 2. store your GO API key as a DSH credential
#    (create the key at https://opencode.ai/auth)
#    → add to ~/.dsh/.credentials.yaml:
#      OPENCODE_GO_API_KEY: sk-...

# 3. restart `dsh web` and hard-refresh the browser page

That's it for the quota widget and /opencode-go command. The CLI reconciles the package's dsh.bundle.patch into the profile's bundle stack automatically — no manual cordis.patch.yml editing, no symlinks.

Usage

• Widget: read it. Collapsed sidebar → percentage badge; expanded → three progress bars with reset countdowns.
• Command: /opencode-go in any conversation prints the three windows as text.

Config reference

key	default	description
key	default	description
---	---	---
apiKeyEnv	OPENCODE_GO_API_KEY	credential reference / env var name for the API key
baseUrl	https://opencode.ai/zen/go	gateway base URL
cacheMs	30000	host-side upstream cache TTL

The usage API

GET https://opencode.ai/zen/go/v1/usage with Authorization: Bearer <key>:

{
  "usage": {
    "rolling": { "status": "ok", "percent": 0,  "resetsAt": "2026-08-14T07:51:13Z" },
    "weekly":  { "status": "ok", "percent": 1,  "resetsAt": "2026-08-17T00:00:00Z" },
    "monthly": { "status": "ok", "percent": 22, "resetsAt": "2026-08-21T13:05:13Z" }
  }
}

Developing / modifying the widget

The browser half is a hand-authored factory bundle (window.__ModuleLoader__.load), because out-of-tree client plugins have no public build pipeline yet. It may only require() modules from the shell module table (react, react/jsx-runtime, and the registered client packages). Edit lib/client.js directly, then restart dsh web and refresh the page — the bundle revision hash changes and the shell loads the new file.

Host changes (lib/index.js) need only a dsh web restart.

Troubleshooting

• Widget missing after restart → hard-refresh the page (Cmd/Ctrl+Shift+R); the boot graph is injected per page load.
• /opencode-go/usage returns 502 with "no API key" → configure the key in ~/.dsh/.credentials.yaml.
• Gateway 401/403 → the key is invalid or the subscription lapsed; check the credential.
• Widget shows an error string → hover the collapsed badge or read the error line in the expanded widget.
