Open Source Workflow Framework - Numel Playground

[dibenedetto]

I would like to present Numel Playground, a graph-oriented framework to build and execute workflows on local models.

The framework is backend-agnostic (currently Agno is supported) and provides, above all: agent chat, loops, script transformation, user interaction, various media access like text, image, audio, video, 3D models, webcam, microphone, screen sharing, and more.

In the meantime, i'd like to share a starting project for memory sharing: A2M-Protocol.

From my point of view, this gets more interesting if the interoperability boundary stays very narrow. A graph workflow framework can coexist well with Agno if agent execution, event streaming, and state handoff are explicit and portable instead of being tightly coupled to one backend''s internal assumptions.

The practical question is whether a workflow built against Agno today would still have predictable behavior if another runtime is plugged in later.

Graph-oriented workflows make sense as an execution model. One layer that usually stays flat even in graph-based systems is the prompt layer — the instructions going into each node are still prose, which means the structure you built into the graph doesn't extend to what the agent is actually told to do.

Typed prompt blocks (role, objective, constraints, examples, output format as separate fields) would let each node in your workflow carry a structured instruction spec rather than a flat string. The graph architecture and the instruction architecture would then match.

I've been building flompt for exactly this, a visual prompt builder that decomposes prompts into 12 semantic blocks and compiles to Claude-optimized XML. Open-source: github.com/Nyrok/flompt

Curious whether Numel Playground has plans for structured prompt nodes or whether instructions are currently freeform strings per node.
