+## Agents
+
+Two agentic flows are provided by haiku.rag:
+
+- Simple QA Agent — a focused question answering agent
+- Research Multi‑Agent — a multi‑step, analyzable research workflow
+
+
+### Simple QA Agent
+
+The simple QA agent answers a single question using the knowledge base. It retrieves relevant chunks, optionally expands context around them, and asks the model to answer strictly based on that context.
+
+Key points:
+
+- Uses a single `search_documents` tool to fetch relevant chunks
+- Can be run with or without inline citations in the prompt
+- Returns a plain string answer
+
+Python usage:
+
+```python
+from haiku.rag.client import HaikuRAG
+from haiku.rag.qa.agent import QuestionAnswerAgent
+
+client = HaikuRAG(path_to_db)
+
+# Choose a provider and model (see Configuration for env defaults)
+agent = QuestionAnswerAgent(
+    client=client,
+    provider="openai",  # or "ollama", "vllm", etc.
+    model="gpt-4o-mini",
+    use_citations=False,  # set True to bias prompt towards citing sources
+)
+
+answer = await agent.answer("What is climate change?")
+print(answer)
+```
+
+### Research Multi‑Agent
+
+The research workflow coordinates specialized agents to plan, search, analyze, and synthesize a comprehensive answer. It is designed for deeper questions that benefit from iterative investigation and structured reporting.
+
+Components:
+
+- Orchestrator: Plans, coordinates, and loops until confidence is sufficient
+- Search Specialist: Performs targeted RAG searches and answers sub‑questions
+- Analysis & Evaluation: Extracts insights, identifies gaps, proposes new questions
+- Synthesis: Produces a final structured research report
+
+Primary models:
+
+- `ResearchPlan` — produced by the orchestrator when planning
+  - `main_question: str`
+  - `sub_questions: list[str]` (standalone, self‑contained queries)
+- `SearchAnswer` — produced by the search specialist for each sub‑question
+  - `query: str` — the executed sub‑question
+  - `answer: str` — the agent’s answer grounded in retrieved context
+  - `context: list[str]` — minimal verbatim snippets used for the answer
+  - `sources: list[str]` — document URIs aligned with `context`
+- `EvaluationResult` — insights, new standalone questions, sufficiency & confidence
+- `ResearchReport` — the final synthesized report
+
+
+Python usage:
+
+```python
+from haiku.rag.client import HaikuRAG
+from haiku.rag.research import ResearchOrchestrator
+
+client = HaikuRAG(path_to_db)
+orchestrator = ResearchOrchestrator(provider="openai", model="gpt-4o-mini")
+
+report = await orchestrator.conduct_research(
+    question="What are the main drivers and recent trends of global temperature anomalies since 1990?",
+    client=client,
+    max_iterations=2,
+    confidence_threshold=0.8,
+    verbose=False,
+)
+
+print(report.title)
+print(report.executive_summary)
+```

 The QA agent will search your documents for relevant information and use the configured LLM to generate a comprehensive answer. With `cite=True`, responses include citations showing which documents were used as sources.
 
 The QA provider and model can be configured via environment variables (see [Configuration](configuration.md)).
