[FEATURE]:Specify sub-agent variant (thinking lvl) from script for token economy

[Solido]

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

When writing script for divide and conquer feature, sub-tasks may not require the same effort than the main agent.

I would like to launch sub-agents from the same provider but with lower or higher thinking level.

Claude prompt can launch Haiku explicitly as an example.

The request is to configure them from the prompt ONLY.

Thanks!

Your request about specifying thinking level from script for sub-agents appears to be covered or related to issue #7138 (variant per agent config). If you're looking to configure this in your agent definitions in AGENTS.md or opencode.jsonc, that feature may already be available.

Feel free to ignore if your use case requires something different than these existing issues.

Heads up — PR #12567 implements this. It reads the parent session's variant and forwards it to the child session in task.ts, so subagents now inherit the thinking level automatically. The inheritance only activates when the subagent doesn't have its own variant configured, preserving explicit per-agent control.

@mugnimaestra +1 for you PR. This is really a core feature when swarming. To my surprise while central in Claude philosophy it's not much present in OpenCode community. Last demo from Claude rely on this same core when lauching judge, workers, coordinators.

Thanks!!
