1 Lease Administration AI Agent, Live in Production.

Lease abstraction is done once, at speed, and everything afterwards depends on it. A reader extracts the rent, the term, the break clause and whatever else they notice into a spreadsheet, and the lease returns to storage. Two failure modes follow. The first is transcription: a notice period recorded as three months when the clause says three months prior to the fifth anniversary, and the difference surfaces when the break is missed. Nothing catches it, because the spreadsheet is now the record and nobody compares it back. The second is subtler and structural — a reader can only extract what is present. A lease of a given type that is missing a service charge cap, or a reinstatement provision, or an assignment right, produces no entry in the spreadsheet and therefore no signal. The absence is invisible.

Lease Abstraction pulls the commercial terms, critical dates and recurring obligations out of a lease, quotes the clause each came from, and flags what a lease of this type should contain but does not. The quoted clause solves the transcription problem by making the abstraction auditable against the source. The absence check solves the second problem, and it is the output that a careful human reader structurally cannot generate — noticing what is not there requires comparing against an expected set rather than reading what is written. One agent covers this process, and its output is an abstraction for review, not a record.
