Quick Review

Excellent skill with comprehensive documentation. The description clearly explains when to invoke this skill (analytics, metrics, traffic analysis, etc.). Task knowledge is strong with detailed setup instructions, authentication guidance, analysis workflow, and troubleshooting steps. The structure is well-organized with logical sections and references to EXAMPLES.md and REFERENCE.md for additional details. Novelty is moderate-to-good: while a CLI agent could theoretically fetch GA data, this skill packages authentication, multi-metric analysis, trend identification, and actionable recommendations in a way that would require many tokens and complex orchestration otherwise. Minor deduction on structure for potentially including too much detail in SKILL.md when some could be in referenced files, but overall this is well-balanced. The skill meaningfully reduces complexity for a common but technical task (GA API integration and interpretation).
