# `Arcana.Agent.Selector.LLM`
[🔗](https://github.com/georgeguimaraes/arcana/blob/main/lib/arcana/agent/selector/llm.ex#L1)

LLM-based collection selector.

Uses the configured LLM to analyze the question and available collections,
then selects the most relevant ones to search. This is the default selector
used by `Agent.select/2`.

Collection descriptions are included in the prompt to help the LLM make
better routing decisions.
