Concept Ledger（概念台账）

Use when conversations produce many ad-hoc terms, metaphors get reused with shifting meanings, or the same idea gets renamed multiple times. Triggers: term confusion, synonym loops, vague concepts entering implementation, naming chaos in brainstorming, vibe coding, or system design sessions. Agent 主动维护一份概念台账——活的术语表，追踪每个概念的清晰度。无需用户学命令。Agent 自动检测命名混乱，在自然对话节奏中适时介入，帮助概念从模糊走向可实现。
