omarchy-opencode-go-usage

Omarchy bar widget for OpenCode Go. Works with any agent (OpenCode, pi, hermes, omp, etc.) that uses your Go API key.

It shows:

• Go limit windows — rolling 5h ($12), weekly ($30) and monthly ($60) from GET /zen/go/v1/usage, with progress bars, reset countdowns and behind-pace highlighting.
• Model catalog — live list from GET /zen/go/v1/models, current $/M from models.dev (includes promos), sorted by cost, quota, or name.
• Picks — computed daily from live pricing: stretch quota (most ~req/5h) and best value (top quota after excluding the stretch winner). Muse Spark excluded (trains on prompts).

The bar is an icon pill. Hover for limit %. Click for the full panel.

Inspired by local.opencode-go.

Install

omarchy plugin add https://github.com/ardfard/omarchy-opencode-usage.git --enable

Put your Go key in ~/.local/share/opencode/auth.json under opencode-go (OpenCode TUI: /connect → OpenCode Go). Other agents use the same key against https://opencode.ai/zen/go/v1.

Remove

omarchy plugin remove local.opencode-go-usage

Dependencies

• curl — Go limits, catalog, and models.dev pricing fetch
• jq — JSON assembly

Limits need an opencode-go key. Catalog and pricing fetches are public.

How prices update

On each refresh (default hourly), collector.sh:

1. Fetches model IDs from https://opencode.ai/zen/go/v1/models
2. Fetches current input/output $/1M from https://models.dev/api.json under opencode-go (this tracks promos, e.g. GLM-5.3-Flash at $0.075/$0.25)

There is no pricing field on the Go API itself. models.dev is maintained by the OpenCode team and updates when rates change.

Stretch quota / best value picks recompute at most once per day from current pricing: estimate ~req/5h as $12 rolling budget ÷ cost per typical agent turn (830 input + 71.5K cached + 295 output tokens). Stretch = highest quota among eligible models; best value = next highest (Muse Spark excluded). Limits and catalog prices still refresh hourly.

Settings (Omarchy Settings → Widgets)

• refreshIntervalSec 60–3600 (default 3600, hourly)
• maxModels 3–30 (default 12) — catalog rows before folding into "other"
• sortBy cost / quota / name (default cost)
