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.
For Remote Control sessions with CLAUDE_CODE_WEBSEARCH_USE_CCR_PROXY=1 set, web searches are now routed through the Anthropic API's session WebSearch proxy (/worker/web-search) instead of directly to the search provider. Error messages from the proxy are surfaced clearly with type-specific descriptions.
Evidence
New L8a() function — search for "ccr websearch-proxy transport error" and "/worker/web-search"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
