Efficient Frontier · flosrn bundle Orchestrate any high-cost frontier model (Fable, Opus) on codebase-heavy or token-heavy work - delegate research, coding, and testing to cheaper subagents, write self-contained handoffs, pick and escalate delegate models, and vet delegated output before relying on it. Hard routing gates, binding whether or not this skill is loaded: never Haiku; anything user-facing (UI, copy, API design) goes to opus-5, fable-5, or gpt-5.6-sol, never grok-4.5 or a cheaper tier; when axes conflict on something that ships, intelligence > taste > cost; opus-5 is the session default. Load this skill for the model table and escalation policy before routing anything else.
