opencheese-session-stats

OpenCode CLI plugin that displays last-request token usage and cost plus cumulative session totals from OpenCheese API responses.

Features

• Last Request: input tokens, output tokens, and cost for the most recent API call
• Session Totals: cumulative tokens, cost, and request count across all requests
• Automatically updates after each API call via response headers

Display

Last: 1,234+567 = 1,801 tokens | $0.0012
Total: 45,231 tokens | $0.0123 | 15 requests

For streaming responses, only session totals are shown (per-request usage arrives via SSE events).

Installation

npm install -g opencheese-session-stats

Then add to your ~/.config/opencode/opencode.json:

{
  "plugin": ["npm:opencheese-session-stats@latest"]
}

Restart OpenCode CLI.

How It Works

The plugin reads response headers set by OpenCheese:

| Header | Source | |---|---| | x-request-input-tokens | Last request input tokens | | x-request-output-tokens | Last request output tokens | | x-request-total-tokens | Last request total tokens | | x-request-cost | Last request cost (USD) | | x-session-total-tokens | Cumulative session tokens | | x-session-total-cost | Cumulative session cost (USD) | | x-session-request-count | Requests in session |

Requirements

• OpenCheese API gateway (sends x-request-* and x-session-* headers)
