Most agent harnesses that have not been designed from scratch for current models are over-engineered.

Chances are whatever was needed to make earlier models perform well now either is no longer helping much or actively hurts performance (worse results, slower, uses more tokens …).

Agreed!

Example: for large Eloqua/Marketo/HubSpot emails we would previously make a planner which delegated the sections to their own call.

GPT5.6 can do the whole thing. The planner is unhelpful.

My suggestion: feature flag your complex implementations so you can rapidly contrast with and without it. (Or a formal eval suite if you have one).

If you prefer the simpler path, delete the old path.

Note: the challenge is making things compatible with these tools. Obviously generating html directly has been simple for ages.
