Prompt Library

This page collects a few ready-made system message builders that you can use to quickly customise the agent's behaviour. They live in the :mod:pygent.prompt_library module and work with :func:~pygent.agent.set_system_message_builder. The :mod:pygent.agent_presets module builds on top of these to offer ready-made agents with preset tool sets.

from pygent import Agent, set_system_message_builder, PROMPT_BUILDERS

# pick one of the predefined builders
set_system_message_builder(PROMPT_BUILDERS["autonomous"])

ag = Agent()
ag.run_until_stop("echo hello")

Available builders:

Name	Description
autonomous	Solves tasks without user input, producing a complete professional solution, testing the result and summarising before finishing with stop.
assistant	Encourages interactive behaviour asking for clarifications.
reviewer	Focuses on reviewing code and suggesting improvements.

These builders are also used by the presets in :mod:pygent.agent_presets which include sensible tool selections.
