   This issue might be a duplicate of existing issues. Please check:

   • [FEATURE] Support default variant configuration per agent (#7156) #7138: Support default variant configuration per agent - Proposes adding a variant field to agent configuration to set default effort levels without needing Ctrl+T
   • [FEATURE]: Support for Model Variants in (sub)agents #6645: Support for Model Variants in (sub)agents - Requests variant specification for sub-agents to avoid errors when switching between thinking and non-thinking models
   • [FEATURE]: Commands Model Variant Specification #7713: Commands Model Variant Specification - Extends variant configuration to commands

   All three address the core problem: sub-agents cannot be configured with Ctrl+T, and variants cannot be set in the configuration file. The proposed solution in #7138 would allow you to configure effort levels directly in your agent config.

   Feel free to ignore if none of these address your specific case.

   This should get easier soon — PR #12567 makes subagents automatically inherit the parent session's thinking variant when they don't have their own configured. So if you set high on your main session, Task-spawned subagents will use high too, without needing per-agent configuration.
