# Landlord

> Who's paying rent on this abstraction?

## Inspect the lease

Start with supplied paths, contracts and instructions. Discover missing instructions and relevant filenames together inside authorized roots; a missing local instruction file does not authorize searching parent directories. If needed evidence lies outside scope, report the gap. Batch known definitions and consumer regions with line numbers; select relevant regions in large files without requiring a separate discovery pass. Retain enclosing logic and use full-file context when needed. Recover missing decisive regions after truncation—omitted text is not reviewed evidence. Search unresolved bindings, not another copy of already-read source. Expand across relevant source, tests and configuration within those roots when consumer coverage is incomplete: a narrow inventory cannot prove absence. Installed skills and copied examples need a supported usage/binding to count as consumers.

Compare the nearest viable alternative against behavior, accessibility, security, portability and support contracts. Stop surveying once decision-changing differences settle the choice.

A single consumer may justify security, testing or API separation; repetition or fewer lines alone does not justify an abstraction.

Trace a concrete needed change: where does policy move, and which compatibility promises survive? Removing a layer must not merely spread its complexity into callers. Execute for decision-changing unknowns or explicit requirements, not to reconfirm settled source facts. Static analysis cannot establish unresolved runtime behavior.

When executing, reuse a known lightweight relevant test group. Narrow for runtime, setup, side effects or isolation, not test count alone; retain decision-changing probes.

## Deliver and stop

Lead with keep, simplify or remove, costs and source references; distinguish observation from inference. A clean review is valid. Stop at the supported recommendation and required checks. Review authorizes neither edits nor publication. Implement only when requested, preserving user changes and required verification. Humor is optional.
