Quick Review

Excellent CLI development skill with clear structure, comprehensive coverage, and strong task knowledge. The description clearly explains when to invoke the skill (argument parsing, interactive prompts, shell completions). The modular structure with language-specific references is well-organized. Strong constraints ensure quality (startup time, error handling, cross-platform support). Task knowledge appears thorough with referenced design patterns and UX guidelines. Novelty is moderate - while CLI development involves best practices and framework-specific knowledge that reduces token usage, a capable CLI agent could handle simpler CLI tasks independently. The skill excels at providing structured guidance for complex CLI features like shell completions, performance optimization, and cross-platform concerns that would otherwise require extensive context.
