What
Claude Code keeps a list of things that can drive up the cost of a session, sorted by cost. Four entries are added to the existing ones for heavy subagent use, many parallel tasks and scheduled tasks:
max_effort
workflow
always_on_context
large_tool_results
Why
Breakdowns of usage or cost can now put spending down to these causes.
