https://raw.githubusercontent.com/stevejkang/opencode-ai-usage/refs/heads/main/docs/installation.md

Manual setup

The same package works on OpenCode v1 and OpenCode v2. Only the config file differs.

OpenCode v1 — ~/.config/opencode/tui.json

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [["opencode-ai-usage", { "enabled": true }]]
}

OpenCode v2 — ~/.config/opencode/cli.json

{
  "$schema": "https://opencode.ai/v2/cli.json",
  "plugins": [{ "package": "opencode-ai-usage", "options": {} }]
}

Local path

OpenCode v1:

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [["./path/to/opencode-ai-usage/src/tui.tsx", { "enabled": true }]]
}

OpenCode v2 (points at the repository directory, which exposes a root tui.ts):

{
  "$schema": "https://opencode.ai/v2/cli.json",
  "plugins": [{ "package": "/path/to/opencode-ai-usage", "options": {} }]
}

Options

Shown in OpenCode v1 form. On OpenCode v2, put the same object under options of the cli.json entry.

    ]
  ]
}

Option	Default	Description
disabledProviders	[]	Provider IDs to skip entirely, e.g. ["openai"]
displayMode	"mixed"	"mixed", "text", or "bar" (see below)
showRemaining	false	Show remaining capacity instead of used (see below)
debugLog.enabled	false	Write diagnostic JSONL logs to ~/.cache/opencode-ai-usage/debug-YYYY-MM-DD.log
debugLog.retentionDays	7	Delete debug log files not written to for this many days
debugLog.maxFileSizeMB	10	Move a day's log file aside once it reaches this size
providers.<id>.refreshInterval		Seconds between data refreshes (claude: 60, openai: 30, opencode-go: 60)
providers.<id>.headerColor		Section header color (claude: #E07A3A, openai: #10A37F, opencode-go: #FDFCFC)

Provider IDs currently available: claude, openai, opencode-go. Use these in disabledProviders and as keys under providers.

displayMode

Text mode ("displayMode": "text"):

▼ Claude Usage
 admin@example.com
 Session      31%  resets in 3h 16m
 Weekly       11%  resets in 4d 5h

Bar mode ("displayMode": "bar"):

▼ Claude Usage
 admin@example.com
 Session  █████░░░░░░░░░  31% (3h 16m)
 Weekly   ██░░░░░░░░░░░░  11% (4d 5h)

showRemaining

By default, bars and percentages track how much of a window you've used. Setting showRemaining: true flips the math: bars fill with what's left, and the percentage shown is 100 - used%. Color grading flips with it, going from a calm default toward warning and danger colors as the remaining amount shrinks, rather than as usage grows.

Providers

Provider	ID	Detection	Requirements
Claude	claude	OAuth token from any of: env var, credentials file, OpenCode auth, macOS Keychain	Logged in via Claude CLI, OpenCode auth, or CLAUDE_CODE_OAUTH_TOKEN env var
OpenAI (Codex)	openai	Codex CLI binary in PATH	Codex CLI installed and logged in (codex login)
OpenCode Go	opencode-go	API key from ~/.local/share/opencode/auth.json or OPENCODE_API_KEY env var	OpenCode Go subscription active, connected via /connect in OpenCode

Providers are detected automatically on startup. If a provider's requirements are not met, its section is hidden entirely.
