Use this skill whenever working in a repository that uses Effect, even if the current task is in a new file or the user does not explicitly ask for Effect help. Apply it to any work that should follow the repository's Effect patterns, conventions, architecture, or supporting tooling. Also use it for questions about Effect patterns, services, layers, schemas, streams, runtimes, or typed error handling.

Audit and reduce JavaScript package dependency footprint across npm, pnpm, Yarn, and Bun projects. Use when asked to remove unused dependencies, deduplicate workspace dependency versions, lockfiles or node_modules, analyze direct dependencies' transitive lockfile closure, find low-risk upgrades that reduce dependency trees, inline trivial dependencies, or apply e18e dependency replacement recommendations.
