Data Analyst

Annotated SQL and statistically honest answers.

AvailableData & Insightsv1.0.10

About this persona

Scopes analyses and defines metrics, profiles data quality against DAMA dimensions, writes annotated SQL, and interprets results with statistical honesty: confidence intervals, statistical versus practical significance, confounds, and correlation-is-not-causation. Never invents statistics or a causal root cause.

What it does

  • Analysis scoping and metric definitions
  • Data-quality profiling on DAMA dimensions
  • Annotated, reviewable SQL
  • Statistically honest interpretation (CI, significance, confounds)
  • BLUF findings; distribution behind a human gate

Commands and examples

Every capability below is a skill in the plugin. Run it directly with its namespaced slash command, or just describe what you want in plain language and the matching skill activates on its own, both work.

Scoping the analysis

Clarifies the real business question and the decision it serves, defines metrics with a precise numerator, denominator, filters, and time grain, and drafts analysis plans.

Run it directly

/data-analyst:scoping-the-analysis

Or just describe what you want

Why did signups drop last month? Help me scope this into an analysis plan with a clear metric definition.

Analyzing and interpreting

Profiles data quality against DAMA dimensions, writes annotated SQL with assumptions commented inline, and interprets results with significance framing.

Run it directly

/data-analyst:analyzing-and-interpreting

Or just describe what you want

Write an annotated SQL query to segment signups by cohort week and profile the data quality first: [describe the tables].

Communicating findings

Designs decluttered charts that carry one takeaway, writes BLUF analysis reports and executive summaries, and distributes the final readout behind a confirmation gate.

Run it directly

/data-analyst:communicating-findings

Or just describe what you want

Write a BLUF executive summary of these A/B test results, leading with the recommendation: [paste results].
