What's Wrong?

Claude repeatedly stopped mid-response at the same point, a backtick.

It seems to be triggered by markdown code formatting with backticks - the rendering cuts off mid-sentence when special characters appear in certain contexts.

Claude instructed me to record this here.

What Should Happen?

Steps to Reproduce

Tell me about thinking vs not thinking (tab toggle)

⏺ I couldn't find detailed documentation about this feature, but I can explain based on how Claude
Code works:

Thinking Mode Toggle:
Claude Code has different thinking modes that control whether you see my internal reasoning:

  • With thinking (interleaved/auto): You see `

when Claude dropped special characters, the response was:

⏺ You're absolutely right, something is wrong with my output. Let me try again without special
characters:

Thinking Toggle (Tab key):

In Claude Code, you can press Tab to toggle whether you see my internal reasoning blocks.

  • Thinking visible: You see blocks labeled "thinking" where I reason through problems step-by-step

before responding

  • Thinking hidden: You only see my final responses and tool calls, making the conversation cleaner

Benefits:

  • Visible thinking: Understand my reasoning process, useful for complex problems or debugging my

logic

  • Hidden thinking: Cleaner interface, faster reading, just see the results

The MAX_THINKING_TOKENS setting in your config enables extended thinking mode, which gives me a
larger budget for complex reasoning tasks.

Does this explanation come through properly?
