The skill provides a clear overview of variance analysis capabilities with good structural organization. The description adequately explains when to use the skill. However, it lacks concrete implementation details - no formulas, scripts, or step-by-step procedures are provided for calculating variances, applying thresholds, or generating waterfall charts. The instructions are high-level directives rather than actionable guidance. While the skill references variance-formulas.md for templates, the core SKILL.md should contain enough detail for an agent to perform basic variance analysis independently. Novelty is moderate; while variance analysis requires domain knowledge, much of it could be accomplished by a capable CLI agent with sufficient prompting. The skill would benefit from including actual Excel formulas, Python/bash scripts for automation, specific threshold values, and detailed waterfall chart generation steps.
