Instinct brings its AI agent to group chats

Claude Code v2.1.290 adds serverToolUses to a mod's turn.step hook result, exposing the API-run tool calls (the advisor) with id, name, input, and start/end times. Plugin hooks gain agentId on tool.check so a hook can distinguish a subagent's permission check from the main session's.

Browserbase's Miguel González Fernández and Microsoft Research's Corby Rosset present research on verifiers for computer-use and web agents, where an official judge scored agent success at 74% while a better verifier put it at 38%.
