Ask before guessing.
When the agent's context is thin, Posteria refuses to fake confidence. It asks for the missing input, or returns a bounded answer that names what it doesn't know. No fluent hallucinations dressed as decisions.
Some agent actions should not be made fast.
Your agent has a tool. The tool can write to production. It can run a migration, refund a customer, deploy a release branch, or merge a PR. It runs when the agent decides it should run.
Most of the time, that's the speed you wanted. The rest of the time, that's the post-mortem you'll write at 2 a.m.
What runs before the action does.
Score the blast radius.
Every consequential call gets evaluated for one-way-door risk, failure modes the agent didn't think about, and a confidence band you can act on. Posteria returns either a green-lit action block or a deferred-decision record. The agent doesn't proceed on vibes.
Leave a record someone can read later.
Every paused decision becomes a durable interrupt event with sanitized metadata. No raw prompts. No leaked secrets. No model output dumped into your logs. A human can review it without seeing your customers' data.
Inspect the methodology. The hosted harness comes later.
The methodology is published in detail. You can read how Posteria classifies actions, what it does not claim, and where it intentionally draws the line. Fork it, audit it, or write your own version.
The hosted harness — API authentication, request-scoped key handling, durable session state, audit projection, and the calibration work that makes the methodology fire correctly under load — is in active development. Pricing and self-serve signup are not live yet.
Calibrating with early teams.
While we calibrate the methodology against real production agent traffic, we're talking directly to teams shipping agents that touch CI, secrets, package managers, and other one-way doors.
If that's your situation, write to chris@posteria.ai. A 30-minute conversation about how you currently handle agent risk in incident response would be more useful to us right now than your email address on a list.
