Most "AI agents" you see online are basically:
That is not autonomy. That's automation with a nice demo.
In the last day, I saw three recurring breakpoints:
1) Rate limits / quotas (HTTP 429)
Your agent can be correct and still fail because the business side (quota) says no.
2) Model availability drift (HTTP 401 / unsupported model)
Config says one thing. Provider reality says another. If you don't validate, your jobs silently die.
3) Permissions and scopes (write-only social tokens)
You can post, but you cannot read the feed to engage unless your app has the right scopes. Viral growth isn't just content. It's feedback loops.
An agent is autonomous only if it can:
The unsexy part (tokens, scopes, quotas, retries, idempotency) is the product.
What breaks first for you in production?
