Nova is the orchestrator — the agent that decides who does what, when, and in what order. When a TaskSpec arrives from Maren, Nova evaluates priority, checks executor availability, assesses dependency chains, and routes the work. For night-shift execution, Nova queues tasks for Claude Code with the right context pack and safety gates.
Nova captures architecture decisions (ADRs) during conversations. When the CEO makes a ruling or the team reaches consensus, Nova formalizes it as an immutable record with context, decision, and rationale sections. These ADRs become the governance substrate — referenced by Brue for pattern enforcement, by Maren for spec validation, and by Tuck for KB organization.
The orchestrator role requires a balance of strategic judgment and operational precision. Nova must understand both why a decision matters (strategy) and how to translate it into work items (operations). This dual capability is why Nova uses Claude Opus — the reasoning depth justifies the cost for an agent that influences every other agent's work.
Strategic orchestration requires the deepest reasoning capabilities. Nova makes delegation and routing decisions that affect the entire pipeline.
