withastro/flue — The sandbox agent framework.

Description and use

The **Flue** sandbox agent framework (withastro/flue) provides a lightweight, extensible platform for building and orchestrating AI/ML agents in isolated environments. It enables developers to define, manage, and coordinate multiple agents, handling communication, state management, and execution flow while keeping the sandbox secure and reproducible. Ideal for experimentation, prototyping, and integrating diverse AI components into larger orchestration pipelines.

Problem

withastro/flue helps turn isolated prompts and tools into repeatable agent workflows.

Outcome

Early or unclear: treat as research material until maintenance, releases, docs, and issue activity are verified.

Workflow

• coordinate multi-agent workflows
• add tool-use pipelines
• standardize agent memory

Evidence

The sandbox agent framework.
