qwen-code Now Requires an Explicit Opt-In Before the Model Starts a Multi-Agent Workflow
PR #9806, merged 2026-08-24, adds a rule to the Workflow tool description telling the model not to fan out unless the user actually asked for orchestration, and enumerates the five acceptable forms of asking (the `workflow` keyword, the user's own words, a skill or slash command that says to, naming a saved workflow, or resuming a run). Instead of silently declining, the model is told to name what it would fan out over and roughly how many agents that is, then let the user decide. Two implementation details worth stealing: the agent count is interpolated from `DEFAULT_MAX_AGENTS_PER_RUN` rather than pasted as prose, and the rule sits above the "what a workflow is for" guidance so it frames it instead of reading as a footnote.
