levain-sdk
The Python interface that Levain agent recipes are written against: node helpers, the agentic engine, state reducers, and tool annotations.
A recipe's node functions import from levain_sdk, so this package is
what makes a cloned recipe installable and readable in your editor —
type checking, completion, and uv sync all resolve against it.
Agents execute on the Levain platform; this package defines the
contract, it does not run them.
Install
Recipe packages already declare levain-sdk, so inside a cloned
recipe:
uv sync
Or directly:
pip install levain-sdk
Extras
models— direct (non-agentic) LLM calls vialevain_sdk.models.review— helpers used by review-oriented recipes.crawler— main-content extraction for crawling recipes.
Most recipes need none of these; the error message will name the extra if a module you import requires one.
Wiki
levain_sdk.wiki reads the workspace knowledge base from node code,
with no agent loop: read_page(path), search(query, limit) and
list_pages(). All three are async, take their configuration from the
sandbox environment, and report failures as {"error": ..., "code": ...}
rather than raising. The
Knowledge Base guide
has the example and the list of codes.
Authoring recipes
Validation and code generation live in the companion tool, levain-cli. The full authoring guide is at docs.levainlabs.com.
