A subagent is a helper Claude starts to work on part of a task. The number is now fixed at 180000, and the server setting `tengu_maple_ferry` is gone.\n\nThe number is still 0 for nested calls, calls started by a hook and the other cases that were already excluded. It is also 0 in two new cases:\n\n- Prompt caching is off. Prompt caching lets the service reuse earlier parts of a conversation.\n\n- Prompt caching is set to one hour.\n\n**Why**\n\nA value that could be tuned from the server is now fixed for eligible background subagents. Where it used to fall back to 0, it now has a real value, so behaviour can differ from before.\n\n- Flag `tengu_maple_ferry`: Not enough to say (read for one account on one subscription tier against v2.1.318; this account: no value returned, anonymous baseline: no value returned, compiled default: not a boolean we can read) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Agents\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
