In v2.1.69 they “simplified” the Agent tool schema. Now there is no way for the main session to select the model the subagent should use or override tools to be allowed for it. Looks like only model and allowed_tools properties on the subagent’s frontmatter now in control. So, if you had “flexible” subagents that you spawn with different models depending on the task at hand, you may be surprised why stack traces, build output, and html dumps are analyzed so slowly (yeah, with main session’s Opus ). And where your weekly limits have suddenly all gone. And now we can only hope the Explore agent actually runs with Haiku and not with the main session model. submitted by /u/the_rigo
