Real Estate: Lease Abstraction with Claude Code: Sandbox Policy

A production playbook for lease abstraction in real estate operations using Claude Code: sandbox policy, run-scoped inputs, logs, typed results, and artifacts.

Audience: Real estate asset management teams

The problem

Real estate asset management teams need lease abstraction to run repeatedly against leases, amendments, rent schedules, options, and obligations. In real estate operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.

Implementation path

Run lease abstraction in an ephemeral sandbox, keep provider credentials in the broker, expose narrow tools, and store logs outside the workspace for review.

Tradeoffs and failure modes

A narrower runtime blocks ambient machine behavior, but it gives security reviewers a concrete boundary. For lease abstraction, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.

Runtime boundary

filesystem: /skill and /skill/.argo/inputs only
network: deny by default
artifacts: /skill/output/artifacts
logs: retained outside sandbox
provider: Claude Code
