opencode-tui-tps

OpenCode TUI plugin that shows tokens per second (tok/s) in the session sidebar.

Features

• Displays the average output speed of the latest assistant message
• Updates live while streaming (uses Date.now() until the message completes)
• Uses the official tokens field from AssistantMessage, no estimation
• Sits in the sidebar_content slot, below the built-in Context block

Install

Add to ~/.config/opencode/tui.json:

{
  "plugin": [
    "opencode-tui-tps"
  ]
}

Restart opencode. The sidebar will show a Speed block with the current output rate.

Development

bun install
bun run build

The plugin registers via module.tui with api.slots.register:

• Slot: sidebar_content (append mode)
• Order: 950 (renders after oh-my-opencode-slim)

Requirements

• opencode >= 1.18.15 (TUI plugin system with module.tui)
