time-series-decomposer

Quick Review

The skill has a clear structure but severely lacks substance. The description is too generic and doesn't explain what time series decomposition actually does (separating trend, seasonality, residuals). There's no task knowledge provided - no steps for decomposition methods (additive/multiplicative), no code for STL/classical decomposition, no guidance on choosing parameters or interpreting results. While time series decomposition is a valuable specialized task that could benefit from automated guidance, this implementation is essentially a template with placeholder text. To be useful, it needs actual decomposition algorithms, parameter selection logic, visualization code, and concrete examples of analyzing decomposed components.
