## Full description
laserbrain is a runtime goal-alignment harness for AI agents. It gives an agent a fixed reference for its intended goal, evaluates subsequent steps against that reference, and looks for signs that execution is drifting, stalling, looping, or spiralling. The aim is to detect unproductive motion early enough to intervene—not merely observe it afterward—so agent workflows use fewer tokens, take shorter paths, and remain more controllable.

What it is

A drift detector for AI agents. It watches a running agent and tells you when it has stopped working on what you asked for — while the run is still happening, not after you read the transcript.

Free and open source on one machine. A hosted service when you have several.

What it does

Agents don't fail loudly. They keep going — competently, expensively — on something adjacent to the request, reporting progress the whole way. Nothing errors. The logs look like success.

Asking the agent doesn't help, because the faculty that would notice the drift is the one that drifted. Self-assessment is the single measurement a system can't make about itself.

laserbrain is the outside observer. Every step it returns one of nine verdicts — grounded, drifting, spiralling, oscillating, wrong-problem and others — plus how far the agent has moved from where it started. It also catches the failure a threshold can't: an agent bouncing between two goals scores fine at every individual step, because the problem is the sequence, not any one reading.

How it works

One idea, and everything follows from it:

The agent states its goal on step one. That statement is frozen where the agent can't reach it. Every later step is scored against it.

The freezing is the product. A reference the measured thing can revise isn't a reference — it drifts along with whatever it's measuring and every reading comes back healthy.

It's a grammar, not a model. No second LLM judging the first, no network call in your loop, no training, no tuning. Verdicts computed locally in single-digit milliseconds.

pip install laserbrain

Or one line in an MCP client config, and any MCP-speaking agent picks up the whole toolkit.

Why use it

Agents checked within a minute of stating their goal drifted 0% of the time in our corpus. Left unchecked past thirty minutes: 67.9% — about two runs in three.

A drifting agent isn't idle. It's working, and you're paying for every token of it.

Free tier is the whole instrument, not a trial — the complete detector, offline, MIT, on one machine, forever. ~20,000 downloads so far.

Paid tiers don't add a better detector. They add a place several machines can meet: laptop, server and CI on one account, drift you can be paged for, history you can read. $20 solo · $40 group · $400 pro · enterprise on contract with an isolated store.

Group and up also unlock laserbrain analytics — upload arbitrary CSV or JSON and the same grammar reads it as a corpus: which vocabulary is rising, which is fading, how far the language has moved from where the data began, and whether it's still moving or has settled.

For anyone running agents unattended — coding agents, research loops, long pipelines. If your agent can burn an hour before a human reads a word, this tells you when that hour went somewhere else.
