Sol Advisor Plugin Released for Codex

The coding agent orchestration plugin Sol Advisor has been distributed via the OpenAI Codex marketplace. This plugin evaluates risk levels before starting a task and requires declaring one of four paths in a machine-readable format: solo, delegate, audit, or full.

The default setting is solo, mobilizing auxiliary agents only when dangerous changes or complex judgments are required. In the auxiliary lane, models from the GPT-5.6 series are fixed for specific roles: Luna (implementation), Terra (high-difficulty judgment), and Sol (read-only review).

The main session handles design, judgment, and final verification, and the specifications passed to auxiliary agents must include goals, file ownership, interfaces, constraints, and verification criteria. By mandating route declarations before calling task tools, the core purpose is to reduce unnecessary delegation round-trips and systematize independent verification for dangerous tasks.
