Pattern: Agent Harnesses Are Converging on Explicit Human Opt-In Before Multi-Agent Orchestration
qwen-code v0.22.2 moves dynamic workflows behind a documented tools.workflowsEnabled user setting, replacing an undocumented environment variable (#9098), and adds an approval dialog showing the script's name, phases and arguments before execution (#9837), on top of refusing a workflow script before it can spend anything (#9873). Claude Code 2.1.246 independently added a confirmation before restarting finished subagents in a dynamic workflow, telling you how many would restart. The shared premise is that fan-out is the expensive irreversible action in an agent harness, so it gets a gate the way a destructive file write does.
