How to create an agent harness without offending Claude's sense of propriety? Don't ask CLAUDE, LOL!!!!!!!!

Bug Description
❯ help me out here - what is it called when the LLM mumbles while it 'thinks'?

It goes by a few names, depending on which part you mean:

  • The reasoning itself is usually called chain of thought (CoT). Other common names are thinking, reasoning tokens and reasoning trace. Anthropic's API calls it extended thinking, and what it returns are thinking blocks. OpenAI calls it reasoning.
  • A condensed version shown to you is a thinking summary or reasoning summary. Many products show a summary of the reasoning rather than the raw trace.
  • The little status words in Claude Code, like "Pondering…" or "Cogitating…", are just spinner verbs. They're decoration and don't reflect what the model is thinking.
  • The short "here's what I'm doing" lines between tool calls are usually called progress updates or narration.

If this is for the console, you probably want the stream of narration and progress during a run. claude -p --output-format stream-json emits each piece as a separate event, so the bubble could show the thinking and progress live instead of just "working…".

❯ stream the thinking into the console bubble, but be careful how you ask, because I am doing it all wrong, apparently:
o ran a one-off edit script from C:\Users\kpkpk\ed-tmp. It is outside the repo and safe to delete.
