Drop the pinned `model: sonnet` from the reasoning-heavy subagents so they
follow the session model instead of being forced down to Sonnet. Running an
Opus session now gets Opus subagents; deliberately dropping to a cheaper
session model is respected too.
Mechanical agents (browser-check, profiler, translator) keep their haiku pin
— that pin is a capability statement, not a stale default, and should hold
regardless of session model.
Mirrors .cursor and .codex structure with Claude model assignments:
- haiku for lighter tasks (translator, browser-check, profiler)
- sonnet for standard tasks (code-quality, plan-implementer, etc.)
