What
When an MCP (Model Context Protocol) server reconnects, Claude Code now re-fetches that server's list of tools and merges them back into the available tools, tracked through a new pending-refresh set. The code also adds timing markers around the tool setup step to measure how long it takes.
Why
This keeps the available tool list accurate after a reconnect, so tools from a server that dropped and came back are properly refreshed instead of possibly going stale.
