This Skill identifies code, features, abstractions, dependencies, and operational burdens that do not justify their continuing maintenance cost, while protecting required behavior, compatibility, and system obligations.
Use the audit-necessity skill to review the specified path and identify safe cuts, worthwhile simplifications, unresolved questions, and justified keeps with evidence and a completion ledger.

Technical debt reduction requires evidence-based necessity analysis that reconstructs runtime paths, capability ownership, and lifecycle obligations to classify code as confirmed cuts, worthwhile improvements, or justified keeps. This ensures continuing maintenance cost does not exceed delivered value.
Necessity analysis is an architecture audit technique that evaluates whether operational mechanisms, abstractions, and data lifecycles justify their continuing cost. It traces consumers, variants, and compatibility requirements to determine safe deletion candidates without losing required system outcomes.
Reducing maintenance cost involves applying necessity analysis to internal abstractions by evaluating usage evidence and total removal cost. Findings are classified into confirmed cuts, unresolved questions, or justified keeps, producing a completion ledger for safe deletion or replacement.
Legacy code should be kept when necessity analysis confirms it fulfills domain obligations, security requirements, or compatibility constraints that outweigh its maintenance cost. Evidence-based evaluation classifies these as justified keeps to preserve required system outcomes and reliability.
Auditing a service folder identifies obsolete feature flags, duplicate mechanisms, and stale support assets by reconstructing intended outcomes and tracing dependencies. Safe reduction planning generates migration paths, rollback plans, and verification needs for each confirmed cut.
