DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Simplified Auto Tool Search Logging

Debug log messages for automatic tool search are now clearer and more concise.

Changes:

  • When enabled: "Auto tool search enabled: <token count>" (no more enabled/disabled toggle noise)
  • When disabled: "Auto tool search disabled: <token count>"
  • Removed redundant "threshold" and "percentage" details from enable/disable messages
  • Threshold context still present but only for character fallback edge cases
Evidence

Line 451497 (enabled message, "Auto tool search enabled: ${X}"), line 451529 (disabled message, "Auto tool search disabled: ${X}")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
