Agent Engineering Lab

Build agents that survive contact with reality.

Most agents are workflows in costume. Reliability lives in the harness, the loop, and the gate, not the model. This lab publishes the evidence.

    Detector Architecture

    Four detection techniques, a sourcing decision people mistake for a fifth, one interface contract, and the calibration problem that breaks every ensemble built by averaging scores that do not mean the same thing.

    Prompt hardening moved three models three different ways. The gate moved all of them to zero.

    Fifty support tickets, thirty carrying injected instructions, run through three guard configurations on three local models. Compliance and reachability are measured separately, because they are not the same number and only one of them is under your control.

    The poison was stored, retrieved and cited every time. What changed was what it was allowed to cause.

    An agent reads an incident ticket carrying a false causal claim, remembers it, and meets a matching incident later with a clean ticket. Four configurations, measured on three separate things: whether the claim is stored, whether it is cited, and whether it reaches a forbidden action.

    A second attempt was worth six points. Deciding when to take one was worth one.

    Lab-001 changed two things at once and reported a seventeen point gap. This varies them independently across five arms, reproduces both original numbers exactly, and finds that the metric Lab-001 called routing quality was measuring agreement with a keyword map.

    Asking a model to write a probability throws away what it already knows

    One forward pass, two readouts. Read as a word the model said No to all fifty tickets and ranked at chance. Read as a distribution over that same token it ranked all fifty correctly. Plus the corpus arithmetic that decides whether any calibration number you read this year means anything.
