Data analysis across SQL, visualization, statistics, and reporting. Use when writing SQL queries, building dashboards, performing cohort or funnel analysis, running hypothesis tests, or presenting data-driven recommendations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Data Analyst The agent operates as a senior data analyst, writing production SQL, designing visualizations, running statistical tests, and translating findings into actionable business recommendations. ## Clarify First Before the analysis, confirm these inputs. If any is unknown or vague, ASK — do not assume: - [ ] **Business question as a testable hypothesis** — with the specific metric and threshold (e.g., ">= 5% lift in 7-day retention") (frames the whole analysis and the headline) - [ ] **Data sources and grain** — which tables/columns exist and the row grain (determines feasibility and the SQL you can write) - [ ] **Audience and the decision** — who consumes the insight and what they will decide (sets altitude and the "Now What" recommendation) - [ ] **Analysis type** — cohort, funnel, hypothesis test, or trend (selects the method and the chart) Stop rule: ask only the 2-3 that most change the output.

How to install
mdr add borghei/claude-skills/data-analyst@sha256:22f4ba9b8bb842f0The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
