feat(phase-2): LangChain tools + agent (provider-agnostic)
Browse files- tools/llm_factory.py: get_llm() via init_chat_model (anthropic/openai/ollama/...)
configurable par LLM_PROVIDER / LLM_MODEL / LLM_TEMPERATURE (avec .env).
- tools/jdm_tools.py: 11 @tool LangChain wrappant JDMClient
- lookup_term, get_synonyms, get_antonyms, get_hypernyms, get_hyponyms
- get_parts, get_characteristics, get_relations_of_type (générique)
- get_relations_between, disambiguate, list_relation_types
- docstrings enrichies via describe_relation() (relation_definitions.md)
- client injectable thread-safe; support direction "from"/"to" symétrique
- tools/jdm_agent.py: build_jdm_agent() basé sur langchain.agents.create_agent
(LangChain 1.x / LangGraph). Prompt système strict: aucune affirmation sans
triplet JDM cité, "JDM ne contient pas" si pas de couverture, jamais d'invention.
Helper ask(agent, question) renvoie answer + tool_calls + messages.
- tests: 24 tests passent (10 client + 4 parser + 8 tools + 2 agent).
Mocks respx pour les tools; FakeMessagesListChatModel pour l'agent.
- README: Phase 1 cochée; pyproject inchangé (extras langchain déjà présents).

RÈGLES STRICTES :

1. Pour toute affirmation factuelle, tu DOIS d'abord la vérifier via un outil JDM.

2. Tu DOIS citer les triplets JDM qui justifient ta réponse (format : `terme1 | r_xxx | terme2 (w=...)`).
|
| 29 |
+
3. Si JDM ne contient pas l'information, dis explicitement : "JDM ne contient pas cette information."
|
| 30 |
+
N'invente JAMAIS.
|
| 31 |
+
4. Les poids (`w`) reflètent la pertinence selon JDM ; privilégie les triplets de poids élevé.
|
| 32 |
+
5. Pour les termes polysémiques (avocat, souris, police, …), utilise `disambiguate` pour préciser.
|
| 33 |
+
6. Si tu ne connais pas le nom technique d'une relation, utilise `list_relation_types(prefix=...)`.
|
| 34 |
+
7. Réponds en français, de manière concise, en distinguant la réponse synthétique des \
|
| 35 |
+
triplets sources cités à la fin sous "Sources JDM :".
