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.

ToolSearch Disabled for Non-First-Party Hosts

Optimistic ToolSearch is now properly disabled when ANTHROPIC_BASE_URL points to a non-first-party Anthropic host, preventing unnecessary tool search requests that would fail.

Evidence

Host check (search for "[ToolSearch:optimistic] disabled: ANTHROPIC_BASE_URL=")

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