The flag is set to true when the call happens under an agent context or a background agent, rather than the main foreground conversation.\n\n**Why**\n\nMarking 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.\n\n- Area: MCP\n- Names: `offCriticalPath`\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5"}
