What

When Claude Code invokes a tool provided by an MCP (Model Context Protocol) server, the request now includes accountMemory data and a new offCriticalPath flag. The flag is set to true when the call happens under an agent context or a background agent, rather than the main foreground conversation.

Why

Marking calls as off the critical path lets the system distinguish tool calls that don't block the user's immediate interaction, which can inform how those calls are prioritized or handled.
