# Agent frameworks converge on one tool-call format

The competing schemas are settling. If you build integrations, this is the week to standardise.

_By Flexitech Digest · 5 Sep 2026_

## What to know

- The competing tool-call schemas have converged.
- One adapter now covers the major runtimes.
- If you maintain integrations, this is the week to standardise.

For two years every framework shipped its own tool-call shape. The schemas have now converged closely enough that a single adapter covers the major runtimes.
