Colang Standard Library (CSL)

View as Markdown

The Colang Standard Library (CSL) provides an abstraction from the underlying event and action layer and offers a semantic interface to design interaction patterns between the bot and the user. Currently, there are the following library files available under nemoguardrails/colang/v2_x/library/ (GitHub link):

Core Flows

Core user, bot, wait, and notification flows.

Timing Flows

Wait, timer, and silence detection flows.

LLM Flows

LLM continuation and utility flows.

Avatar Flows

Gesture, posture, and avatar-related flows.

Guardrail Flows

Standard guardrail flow definitions.

Attention Flows

User attention tracking and checks.

To use the flows defined in these libraries you have two options:

  • [Recommended] Import the standard library files using the import statement: e.g. import llm
  • Copy the corresponding *.co file directly inside your Colang script directory.

Note that the import <library> statement will import all available flows of the corresponding library.
