Say what reader_for and an empty sources mean
`reader_for` documented None as covering any database it could not place, but a
name outside the set raises `KeyError` like `clients_for` does: provenance
naming a database this client does not cover is wrong rather than absent. None
means one thing, a federated client given no name.

`sources=[]` means two things. On a search it selects nothing to search; on the
constructor it raises, since a client over no database can do nothing. Both are
written down now.

A capability reads through a lent client, so what a citation records is that
client's database and not the scope the capability was built with. Chat lends
one, and had no test saying so.

haiku.rag-slim

Opinionated agentic RAG powered by LanceDB, Pydantic AI, and Docling - Core package with minimal dependencies.

haiku.rag-slim is the core package for users who want to install only the dependencies they need. Document processing (docling), and reranker support are all optional extras.

For most users, we recommend installing haiku.rag instead, which includes all features out of the box.

Installation

Python 3.12 or newer required

Minimal Installation

uv pip install haiku.rag-slim

Core functionality with OpenAI/Ollama support, MCP server, and Logfire observability. Document processing (docling) is optional.

With Document Processing

uv pip install haiku.rag-slim[docling]

Adds support for 40+ file formats including PDF, DOCX, HTML, and more.

Available Extras

docling, tui, voyageai, cohere, zeroentropy, cross-encoder, jina, s3, ingester, and one per model provider: anthropic, google, groq, mistral, bedrock, vertexai. Ollama and any OpenAI-compatible endpoint need no extra.
