analyzing-time-series

Comprehensive diagnostic analysis of time series data. Use when users provide CSV time series data and want to understand its characteristics before forecasting - stationarity, seasonality, trend, forecastability, and transform recommendations.

Quality

Content

93%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

An efficient, actionable skill body with copy-paste-ready commands, a clear workflow, and exemplary progressive disclosure into a real reference file. The only gap is the absence of an explicit validation checkpoint in the workflow, though the workflow is non-destructive.

DimensionReasoningScore

Conciseness

The body is lean and well-organized — input format, three workflow steps with commands, options table, output tree, and a one-line dependency list — with no padding and no explanation of concepts Claude already knows, matching the score-5 anchor 'every token earns its place'.

5 / 5

Actionability

Provides copy-paste-ready executable commands (`python scripts/diagnose.py data.csv --output-dir results/`), concrete option flags with defaults, and a full output-file tree, covering the common cases fully and matching the score-5 anchor.

5 / 5

Workflow Clarity

A clear three-step sequence with an explicit coordination checkpoint ('Run after diagnose.py to ensure ACF/PACF plots are synchronized with stationarity results'), but it lacks an explicit validate/verify-then-proceed feedback loop; not a 5 because no validation step is present, though the destructive/batch cap does not apply since the workflow is read-only analysis.

4 / 5

Progressive Disclosure

Body is an overview that clearly signals a single one-level-deep reference (`See references/interpretation.md for guidance on:`) to a real file, with bulk interpretation material split out and scripts located in `scripts/`, matching the score-5 anchor for well-signaled one-level references.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-structured description that explicitly states both capability and trigger conditions in third person. It enumerates concrete diagnostic dimensions and uses natural user language, with only minor room for additional synonyms.

DimensionReasoningScore

Specificity

Names the domain ('Comprehensive diagnostic analysis of time series data') and enumerates several concrete diagnostic dimensions — 'stationarity, seasonality, trend, forecastability, and transform recommendations' — which is several specific capabilities with only minor gaps, matching the score-4 anchor; not a 5 because the actions are characteristics assessed rather than a comprehensive list of distinct concrete operations.

4 / 5

Completeness

Clearly answers both 'what' (diagnostic analysis of stationarity/seasonality/trend/forecastability/transform recommendations) and 'when' with an explicit 'Use when users provide CSV time series data and want to understand its characteristics before forecasting' clause, matching the score-5 anchor exactly.

5 / 5

Trigger Term Quality

Natural user-facing terms appear — 'CSV time series data', 'understand its characteristics before forecasting', 'stationarity, seasonality, trend' — giving good keyword coverage; a 5 would require synonyms/file extensions (e.g., 'TS', 'ARIMA', '.csv', 'seasonal') which are not all present.

4 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (pre-forecast time-series diagnostics) with distinct, specific triggers; minimal realistic conflict risk with other skills, matching the score-5 anchor.
