handlebar-core 0.1.0

Core primitives for Handlebar agentic AI governance

Handlebar Core

Core primitives for running Handlebar governance for AI agents built in Python. This codebase should typically be used in conjunction with a framework-specific Handlebar SDK, such as [google-adk][handlebar-google].

Note: This package in early development and the interface is subject to change.

Features

Short-term roadmap:

• Rule engine for allow/block tools, based on:
  • user category
  • rule category
• Tool ordering + execution time checks
• custom checks for rules (numeric tracking; boolean evaluation)
• Audit telemetry + consumers
• Agent lockdown + human-in-the-loop actions

Roadmap

Handlebar is in early development. We have a lot of functionality planned, but need your feedback on what you need to help you build better agents.

• Please feel free to open an issue if you have any feedback or suggestions
• or join our Discord to talk to us directly

Getting started

The core package should be used alongside a framework-specific Handlebar SDK, such as google-adk. Refer to that package's README for more information.

handlebar-core exposes core primitives for building rules and a governance runtime. In particular, it defines "rules" to enforcing tool-use behaviour based on information like a tool's category, the user on who's behalf the agent is acting, and tool use parameters.

N.b. Our developer docs are incoming.

We welcome contributions from the community: bug reports, feedback, feature requests
