Real accounts for your coding agent. Gone when it's done.

Follow one run

An agent working on Brightline, an invoicing app, has to fix the Pay now link in the overdue reminder email. Here is everything Condition does for it.

What you write

1. 01

   Your app describes a scenario

   Four functions in your own code: build the state, prove it through your app, give out logins, remove it again. Condition never touches your database.

   scenarios: {
     "past-due-invoice": {
       actors: [
         { name: "owner", login: true },
         { name: "customer", inbox: true },
       ],
       prepare, verify, login, cleanup,
     },
   }

2. 02

   Your agent asks for it

   Over MCP the agent gets a ready run, working logins for each person in it, and a real inbox that receives your app's email.

   const run = await condition({
     scenario: "past-due-invoice",
   })
   
   const mail = await inbox({
     runId: run.id,
     actor: "customer",
     waitSeconds: 60,
   })

3. 03

   Condition cleans up

   Reset removes exactly what the run made. Forgotten runs expire on their lease, and a cleanup that fails stays visible until it succeeds.

   await reset({ runId: run.id })
   // released: every row and inbox is gone
