Use when the user says Arcgentic, asks to use Arcgentic, or wants an idea taken through a complete plan → development → self-audit → external audit workflow in Codex.
Use when running Arcgentic V2 in Codex and the current thread must orchestrate fixed Planner, Developer, Test, and Auditor role threads.
Use when running Arcgentic V2 in Claude Code and fixed Planner, Developer, and Auditor role sessions must be coordinated through a broker.
Main-session orchestrator for arcgentic rounds. Use when in single-session mode, when a project-level session mode must drive dispatch order, or when manually advancing the state machine. Dispatches role sub-agents, verifies structured outputs, and owns PASS-only close-round execution.
Use when a project has not yet stored session mode, when a user asks for complete arcgentic workflow execution, or when role identity handoff prompts are needed.
Detect recurring P2/P3 audit patterns across recent rounds and promote them into lesson cards. Use after round boundaries or when repeated findings appear.
Use when a planned round handoff exists and needs to be implemented end-to-end via the 4-commit chain (entry-admin → BA design → dev body with inline CR + SE → state refresh + self-audit). Dispatches ba-designer / developer / cr-reviewer / se-contract sequentially.
External-audit role for arcgentic rounds. Loaded when arcgentic state.yaml is in awaiting_audit or audit_in_progress, OR when the user explicitly requests an external audit of a finished round, OR when reviewing a handoff doc + commit chain against the round's declared scope. Produces a PASS / NEEDS_FIX / AUDIT_INCOMPLETE verdict document with mechanically-verifiable fact table, structured findings (P0-P3), and applies the lesson codification protocol. The output verdict file IS the handoff — do not paste verdict text into chat.
