What problem does it solve? Monorepos managed with Turborepo often suffer from misconfigured build pipelines, broken cache behavior, circular package dependencies, and unsafe publishing workflows that silently ship stale or broken code. This Skill audits the full monorepo setup and produces a structured findings report. ## Core Features & Use Cases - Pipeline and task graph audit: Validates turbo.json dependsOn, inputs, outputs, env, and globalDependencies definitions, and inspects the build graph via turbo run build --dry=json for ordering and circular dependency issues. - Cache correctness analysis: Detects false cache hits from overly narrow inputs, cache misses from generated files, missing environment variables in cache keys, and remote cache misconfiguration. - Shared package and versioning review: Checks exports maps, composite: true tsconfig settings, peer dependency placement, and Changesets publish safety. - Use Case: A team's CI builds take 15 minutes and occasionally deploy staging configuration to production. Run this Skill to find that NEXT_PUBLIC_API_URL is missing from turbo.json env and that remote caching is not enabled, then get a severity-ranked remediation table. ## Quick Start Review this Turborepo monorepo's turbo.json pipeline, cache configuration, and workspace package structure, then report any build correctness or caching issues.
