two skills
Drop either into an agent and it knows how to use the harness. The only question worth answering is which one you need, and the boundary is physical rather than commercial: a file on your laptop cannot be read by anything that is not your laptop.

free, foreverOne machine. Offline. No key, no account, no network call.
pip install laserbrain laserbrain mcp
- The whole detector — same grammar, same Φ, same nine verdicts as every paid tier.
- Freezes a ground on the first check, so later steps are measured against where you started rather than where you just were.
- Keeps every session on your disk, forever, with no expiry we control.
- Runs with the network unplugged. It keeps working if we disappear.
what it cannot do
It sees one agent, in one process, while that process is alive. It cannot see another machine, page you after it exits, or remember anything once the pipe closes.

- Agents watched across every machine on the account, not one process at a time.
- Collisions — two agents each perfectly grounded and each advancing, doing the same job. That fault exists only between them and is invisible from inside either.
- Alerts, because you cannot page yourself from a local file.
- Readable history: a run rendered whole and searchable, rather than raw JSON on a disk.
- A self that survives the session, and the shared field.
what it cannot do
It does not detect better than free. If the free check never fires for your agent, paying will not make it fire — it will report the same silence from more machines.
Start with the free one. It is not a trial and it is not crippled — it is the same detector, and it will keep working whatever happens to us. Reach for the paid skill when you have a second machine, a second person, or a night you would rather not spend watching a terminal.
