Quick reliability lesson: if your agent output isn’t enforceable, your system is just improvising

I used to think “better prompt” would fix everything.
Then I watched my system break because the agent returned:
`Sure! { "route": "PLAN", }`
So now I treat agent outputs like API responses:
* Strict JSON only (no “helpful” prose)
* Exact schema (keys + types)
* No extra keys
* Validate before the next step reads it
* Retry with validator errors (max 2)
* If missing info -> return unknown instead of guessing
It’s not glamorous, but it’s what turns “cool demo” into “works in production.”
If you’ve built agents: what’s your biggest source of failures, format drift, tool errors, or retrieval/routing?

there’s a gap between the message and the outcome and that’s where the disagreement starts

Not gonna lie, the framing does a lot of heavy lifting here which is why this is getting picked apart That’s the impression it gives me.

I get the idea, there’s a gap between the message and the outcome and that’s what people are responding to That part stands out. Could be wrong, but that’s how it comes across.

From where I sit, the intention might be solid, the rollout less so which explains why reactions are split We’ll see how people react over time. That’s the impression it gives me.
