# `Puck.Baml`
[🔗](https://github.com/bradleygolden/puck/blob/v0.2.25/lib/puck/baml.ex#L2)

Built-in BAML functions shipped with Puck.

This module compiles BAML files from Puck's priv directory, providing
built-in functions that work without users needing to write `.baml` files.

Users configure their LLM provider via `client_registry` at runtime,
overriding the placeholder `PuckClient` defined in the BAML source.

## Available Functions

- `PuckSummarize` - Summarizes conversation text (called via `Puck.Baml.PuckSummarize`)

## Example

    registry = %{
      primary: "claude",
      clients: [%{
        name: "claude",
        provider: "anthropic",
        options: %{model: "claude-sonnet-4-5", api_key: System.get_env("ANTHROPIC_API_KEY")}
      }]
    }

    {:ok, summary} = Puck.Baml.PuckSummarize.call(
      %{text: "User: Hello\nAssistant: Hi there!", instructions: "Summarize this."},
      %{client_registry: registry}
    )
