31 portable AI-powered skills that turn Claude into a hands-on analytics partner
No setup required · Works for any company or industry
A structured library of skills (reusable instruction sets) that Claude activates on demand to help with every stage of the analyst workflow: from data quality checks and deep-dive analysis, through documentation and dashboards, all the way to stakeholder communication.
Note
Traditional AI assistants require extensive upfront configuration — schemas, metric definitions, business rules — before they're useful. These skills work on-demand.
| Traditional approach | These skills |
|---|---|
| Needs prep before use | Zero setup required |
| Breaks when business rules change | Adapts naturally |
| Company-specific, hard to share | Portable across any org |
| Silent on assumptions | Teaches you what context matters |
Each skill asks targeted questions to gather exactly what it needs, then executes a complete, structured workflow.

Tip
Describe your task to Claude naturally — it will select and activate the right skill automatically. No slash commands needed.
Example:
You: "I need to understand why our activation rate dropped 12% last week"
Claude: [activates root-cause-investigation, asks for metric data and context]
You: [provides data and business context]
Claude: [runs structured investigation with hypothesis testing]
| You need to... | Start here |
|---|---|
| Explore an unfamiliar dataset | programmatic-eda → data-quality-audit |
| Write or review SQL | query-validation + schema-mapper |
| Understand a metric drop/spike | root-cause-investigation |
| Analyze experiment results | ab-test-analysis |
| Build a dashboard | dashboard-specification + visualization-builder |
| Present to leadership | executive-summary-generator + insight-synthesis |
| Document your methodology | analysis-documentation + analysis-assumptions-log |
| Start a complex analysis | analysis-planning first, always |
Each skill follows the same on-demand context pattern:
- Request minimum viable context — Claude asks only what's essential to start
- Execute the workflow — structured, step-by-step analytical process
- Surface assumptions — anything uncertain is flagged, not silently assumed
- Deliver a consistent output — templated result you can share or iterate on
Note
Skills degrade gracefully: if you can't provide everything, Claude states what it's assuming and proceeds.
Skills work out-of-the-box. To make them company-specific, add a references/ folder inside any skill with:
skill-name/
├── SKILL.md
└── references/
├── company-schema.md ← your table/column definitions
├── metric-definitions.md ← standard metric formulas
└── business-rules.md ← thresholds, edge cases, etc.
Claude will pull this context automatically when the skill runs.
