What problem does it solve? Coding agents waste context re-exploring repositories on every session: they open irrelevant files, miss call sites, edit the wrong module, or pick dead code paths because names are unsearchable and structure is inconsistent. This Skill audits a codebase specifically for how easily an agent can navigate it and produces concrete, cost-ranked structural fixes. ## Core Features & Use Cases - Task-driven navigation audit: Attempts a real task in the repo first, recording which files were opened unnecessarily, where guesses were needed, and which searches returned too much, turning actual failures into findings. - Cost-ranked findings: Flags unsearchable names, missing entry points, untyped boundary data, duplicate authority, oversized files, non-mirroring tests, and undiscoverable commands, each with a location, concrete cost, and fix. - Migration mode: For repo-wide restructuring such as splitting client from server or breaking up a monolith, produces a phased plan ordered by reversibility with a stated payoff, breakage risks, and a stop condition. - Use Case: An agent keeps editing the wrong of two similar route-handler directories. Run the audit to identify the duplicate-authority finding and get a recommendation to consolidate or mark the dead path. ## Quick Start Ask the agent to audit this repository for navigability and report the highest-cost structural problems with fixes.
