Claude Code sends 33k tokens before reading the prompt; OpenCode sends 7k

This was the initial anecdotal evidence, but we undertook this small study to collect empirical data:

We added logging between the agentic coding tool (Claude Code and OpenCode) and Anthropic's endpoint, and captured all requests (and the returned usage blocks).

With one caveat (toward the end of the post) we found unambiguously that Claude Code was far more inefficient in terms of its cache strategy and its harness token usage than OpenCode.

Show HN: Agent Draw: An agent draws while you talk, built on TLDraw

2026-07-06 @ 14:50:06Points: 41Comments: 15

We started wondering what it would take to put an agent in that loop, as an opponent or a rival guesser, and dug into how an agent could read and draw on a tldraw canvas. That research turned into:

Agent draw, a tool that lets an agent draw to the canvas for you while you present.

You can try it right now, or grab the source:

Here you can see the agent assisting me in my demo presentation of a third grade chemistry class:
