You'll notice
Forked inline subagents now start with an empty tool-call replay log instead of inheriting the parent's
What
When launching a forked (inline) subagent, Claude Code previously built its tool-call replay log either by reusing an existing one from tool state or reconstructing it from resume messages. It now always starts the forked subagent with an empty log.
Why
This means a forked subagent no longer carries over its parent's history of prior tool calls into its own replay log, giving it a clean slate rather than inherited context from the parent session.
