dsh-opencode-go-usage

OpenCode Go plan usage monitor for DeepSeek Harness: a floating dock in the
web GUI showing the 5h-rolling / weekly / monthly quota windows with live
reset countdowns.

Data comes from the official quota API
(GET https://opencode.ai/zen/go/v1/usage, Bearer API key; no workspace id,
no cookie).

Install

# From npm (the Web GUI runs on the `web` profile):
dsh plugin --profile web add @xueayi/dsh-opencode-go-usage
# Or from a local checkout:
dsh plugin --profile web add /path/to/dsh-opencode-go-usage
# Upgrade to the latest version:
dsh plugin --profile web update @xueayi/dsh-opencode-go-usage

Restart the profile afterwards (dsh web for the browser UI).

Configure

Recommended: pick the official-channel OpenCode Go provider in
Web Settings → Models and enter the API key there; nothing else is needed.

The API key is resolved per refresh through ctx.credentials under the
apiKeyEnv reference (default OPENCODE_GO_API_KEY) — it can also be stored
manually in ~/.dsh/.credentials.yaml or an environment variable:

- insert:
    - id: opencode-go-usage
      name: '@xueayi/dsh-opencode-go-usage'
      config:
        apiKeyEnv: OPENCODE_GO_API_KEY
        refreshMs: 60000

Usage dock

A glassy floating dock at the bottom-right corner (the web shell owns no
bottom-right slot; mounted through a body portal):

• Badge (collapsed): three mini double rings show all three quota
  windows at a glance — the outer ring is the remaining quota share
  (a full ring when nothing is used yet, shrinking as quota is spent; the
  arc is threshold-colored by spent share: green <60% / orange ≥60% /
  red ≥85%, so a nearly-empty ring reads red), the inner ring is the
  window's remaining time until its next reset (brand blue, shrinking
  live with the window period); beside them an exact 5h-rolling countdown
  (↻3h25m) and a live health dot.
• Panel (click to expand): one row per window (5h Rolling / Weekly /
  Monthly) with a double usage ring (remaining quota outer + remaining
  time inner), the used/remaining percent (preceded by a tone-colored dot:
  green/amber/red for the spent share, a blue dot before the reset
  countdown restating the inner ring color), and a live reset countdown;
  the footer holds the update timestamp, a "Console ↗" link to the
  OpenCode Go console, and a manual refresh button.
• Unconfigured/error states render inline with configuration guidance; a
  failed fetch never blanks the dock.

Display stability

Data and health are decoupled: when a refresh fails (timeout, API error), the
dock keeps showing the last successful sample — the status dot turns
yellow and a quiet "refresh failed, showing previous data" note appears in
the panel footer. The display is never blanked; error / unconfigured states
appear only before the first successful fetch.

The status dot and the manual refresh action reuse the shared
dsh-client-ui-primitives (StateDot / Button) so the dock's affordances
stay visually consistent with the rest of DSH. The dock also honors
prefers-reduced-motion (a reduced-motion environment skips the pop and ring
tweens and closes the panel without the exit animation), and the floating
badge / panel are offset by the viewport's safe-area insets so they never sit
under a notch or home indicator.

Model Experience

Request surface and condition

The plugin exposes no model-facing surface: the model never sees quota
values, no prompt text or tool schema is added.

Token effect

None — no model request, no injected tokens.

KV Cache effect

None — no request tokens added or replaced.

Known Limitations and Deferred Work

• Poll latency — the collapsed badge polls every 60s, the open panel
  every 10s; quota changes appear within at most one poll cycle.
• Data freshness — after repeated failed refreshes the dock keeps showing
  the last successful sample, which grows stale until a refresh succeeds.
• Single account — one API key per profile; multi-account dashboards are
  out of scope.
