Claude told me it stopped debugging since it would run out of tokens in its context window. I asked how many tokens it had left and it said actually it had plenty so could continue. Then again it stopped, and without me asking about tokens, wrote

Context Usage • Used: 112K/200K tokens (56%) • Remaining: 88K tokens • Sufficient for continued debugging, but fresh session recommended for clarity

lol. I said ok use a subagent for clarity.
