Opus 4.1 retires August 5. Do you know what your client agents run next?

Paste one agent's config. Get a sealed report in your inbox: measured token inflation on your actual prompts, parameters that now return 400s, and every provider retirement date ahead of you.

Built for agencies running client agents on the raw API, Vapi, Retell, or n8n — where provider changes land on you. Fully on Make or GoHighLevel? The platform absorbs most of this event class; the free check will tell you that, too.

Your operation Which stack are your client agents on? How many client agents do you operate? Work email — we'll send the sealed report there

One report email — no newsletter, no sequence. We store what you submit and the derived measurements to produce the report; deleted after 90 days unless you become a customer. No resale, no training use. Every number in the report comes from sealed runs — method & published dataset. You will not find the sentence "your agent still works" in our reports, because no static check can honestly promise that.
