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.
The AI-powered session search feature (which used a subagent with Grep/Read tools to find matching sessions) has been removed. The /resume UI now loads past sessions by listing them directly rather than running an agentic search.
Evidence
"Agentic search found", "Agentic search response:", "agenticSessionSearch: query loop failed" — all removed (search for "C4o" — absent in new version)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
