Redesign README.md files with modern GitHub styling — badges, icons, tables, ASCII diagrams, and anchor navigation. Use when asked to restyle, modernize, or redesign a README with shields.io badges, section icons, or visual improvements.

Create or update lightweight phased development plan markdown documents for implementation work. Use when the user asks for a 개발 계획 문서, 구현 계획, dev plan, phased implementation plan, implement_*.md, checkbox-based task plan, or asks to formalize scope before coding.

Plan and coordinate parallel development workstreams across a codebase. Use when the user asks to parallelize implementation, split work into multiple PRs/agents, define file ownership boundaries, coordinate sub-agents, reduce merge conflicts, manage dependencies, or create a merge/integration plan for concurrent changes.

Engineering-manager style implementation plan review. Use when asked to review architecture, lock in an execution plan, assess data flow, edge cases, test coverage, performance, rollout risk, or perform an engineering review before coding.
