Error Message

▎ Suggested fixes: (1) under high effort, cheap-pinned built-ins inherit the session model unless model: is set; (2) warn when a sub-agent runs below

Root Cause

Bug Description ▎ Title: high-effort (ultracode) session tier does not propagate to workflow/sub-agent model selection ▎ Version: 2.1.156 · Severity: Medium (silent correctness degradation) ▎ ▎ Summary: A high-effort posture (ultracode = "correctness over cost") does not propagate to sub-agents spawned via Workflow/Agent. Built-in agents with a ▎ pinned model (Explore → Haiku 4.5) run cheap regardless of session tier, with no warning. The idiomatic way to satisfy ultracode silently defeats it. ▎ ▎ Resolution precedence (the defect): explicit model: > agent's pinned model > inherit session. Because Explore is pinned, it never reaches "inherit ▎ session," and session effort is never consulted. ▎ ▎ Evidence (same workflow): Explore + no model: → 642× Haiku 4.5, zero other models. Explore + model:'opus' → 258× Opus 4.8. Run A's ▎ adversarial-verification phase ran pure judgment on Haiku. ▎ ▎ Evidence (same workflow): Explore + no model: → 642× Haiku 4.5, zero other models. Explore + model:'opus' → 258× Opus 4.8. Run A's ▎ adversarial-verification phase ran pure judgment on Haiku. ▎ ▎ Suggested fixes: (1) under high effort, cheap-pinned built-ins inherit the session model unless model: is set; (2) warn when a sub-agent runs below ▎ session tier; (3) router refuses cheap models for judgment-typed (schema/verification) calls.
