It takes natural language utterances, recognizes which intent they represent, and executes the appropriate action. It provides: + +- **IntentRecognizer trait** — abstraction for matching utterances to intents +- **RegexIntentRecognizer** — P1 built-in; uses regex patterns (HA classic style) +- **IntentHandler trait** — abstraction for handling recognized intents +- **5 built-in handlers** — `HassTurnOn`, `HassTurnOff`, `HassLightSet`, `HassNevermind`, `HassCancelAll` (mirrors HA's classic intents) +- **RufloRunner trait** — abstraction for delegating complex actions to Ruflo agents +- **NoopRunner** — P1 stub; real `tokio::process` subprocess integration in P2 +- **AssistPipeline** — wires utterance → recognizer → handler → response + +Each component is trait-based so recognizers can be swapped (regex in P1, semantic embeddings in P2) without changing the pipeline. + +## Features + +- **Regex pattern recognition** — utterance matching via compiled regex (P1) +- **5 built-in intents** — Turn On, Turn Off, Set Brightness, Nevermind, Cancel All +- **Intent entities + slots** — recognized patterns capture entity names and parameters (e.g., "turn on light.kitchen" → entity: light.kitchen) +- **Intent responses** — structured response with optional text, card (tile data), and conversation context +- **Ruflo agent bridge** — submit complex intents to Ruflo agents for multi-step workflows (P2 subprocess) +- **Trait-based recognizers** — pluggable: `RegexIntentRecognizer` (P1), `SemanticIntentRecognizer` (P2, ruvector embeddings) +- **Trait-based handlers** — extensible: built-in HA-mirroring handlers + custom handlers +- **No external STT/TTS** — this module handles NLU only;
