I am not going to trust a single number thrown by these AI hustlers written in that salesman voice.

Leave alone 97%.

> Your agent calls 20 tools. Each returns 500-3,000 tokens wrapped in {"content":[{"type":"text","text":"..."}]}.

This is a problem with your tool design. Most MCPs are fully vibe coded without any thought about tool selection.

> On a 128K context window, that's 30-55% gone. Not on work. On syntax.

Tool output is not "syntax" you donkey clanker.

Again, use the code approach, let the LLM filter out the JSON using tools. This TOON thing is just vibes. Most of the time your tool output should not even be JSON. It should be well formatted markdown. In cases where it's large structured data, your LLM should have tools (code / jq) to dissect it. So TOON is pointless.
