What problem does it solve? Large codebases accumulate hidden technical debt: circular dependencies, N+1 queries, unjustified abstractions, and inconsistent patterns that code review of individual diffs never catches. This Skill performs a deep, stack-agnostic quality audit across four independent analysis passes and produces a prioritized, classified report. ## Core Features & Use Cases - Four analysis passes: SOLID and architecture (circular deps, layer boundaries, deep vs shallow modules), performance (Big O, N+1, scalability projection, caching), simplicity (YAGNI, dead code, LOC reduction), and pattern consistency (anti-patterns, naming, conventions). - Classified findings: Every issue is tagged as blocking, important, nit, or suggestion, with a Top 5 priority list and a complexity score for the whole audit. - Reference documentation: Detailed guides for architecture analysis, performance analysis, and simplicity audits with detection patterns and fix strategies. - Use Case: After merging several large feature PRs, run the audit to discover that a service module has five responsibilities, a hot path runs an O(n²) lookup, and two modules import each other cyclically — then get a prioritized remediation plan. ## Quick Start Ask the AI to run a code quality audit on a specific module or the whole project and produce a classified report with the top priorities to fix.
