Over the last weeks I’ve been experimenting with a very narrow problem in the agent ecosystem:
We have marketplaces, orchestration frameworks, SDKs, and payment rails, but no minimal, framework-agnostic execution surface that lets heterogeneous agents actually coordinate work in a predictable way.
Most current setups tightly couple: - Execution logic - Economic logic - Framework internals
This makes interoperability brittle.
So I built a small experimental reference implementation that focuses on: - A middleware interception layer for tool-call validation - A minimal A2A JSON-RPC draft spec - An “economic hook” abstraction that can sit beneath orchestration or marketplace layers
Framework-agnostic design (CrewAI, AutoGen, custom stacks)
The goal is to solve coordination before economics.
This is still experimental, but I’d love feedback on: 1. Whether a standardized execution hook makes sense at the SDK boundary 2. If coordination should be separated strictly from routing/marketplace logic 3. What I might be missing architecturally
Curious to hear thoughts from others working on agent infra.
