Ln 830 Code Modernization Coordinator

levnikolaevich/claude-code-skills
225 installs533 stars
Summary

Orchestrates code modernization by delegating to workers that replace custom code with OSS alternatives and optimize bundle sizes. Built on a runtime contract that enforces phase gates, checkpoint validation, and machine-readable summaries. You'd reach for this after an audit when you need to act on findings systematically rather than patching things manually. The coordinator won't advance until each worker emits valid JSON artifacts, which is strict but means you get a deterministic report instead of guessing what actually shipped. Handles partial failures gracefully and keeps successful changes even when one worker bombs out. If you're modernizing a single module by hand, you probably want the workers directly.

improve

shadcn/improve

Survey any codebase as a senior advisor and produce prioritized, self-contained implementation plans for OTHER models/agents to execute. Strictly read-only on source code — never implements, fixes, or refactors anything itself. Use when asked to audit a codebase, find improvement opportunities (bugs, security, performance, test coverage, tech debt, migrations, DX), suggest features or where to take the project next (roadmap, product direction), or generate handoff plans for another agent to implement.
