dmk-intent-vocabulary

Map developer intent and natural language to the correct Ledger Device Management Kit (DMK) components, operations, and API methods. Use when a developer's request is phrased informally, incompletely, or in terms of outcomes rather than API methods, when the intent is ambiguous and needs mapping to a specific DMK component or operation, or when a developer asks 'how do I...', 'what's the difference between...', or describes a symptom rather than an API.
