Does Data analyst work with Claude Duet?

Not verified. Data analyst is a plugin from Anthropic’s Claude ecosystem. We have not verified this exact package inside Duet.

The announcement says Duet carries over account skills and connected apps and can use marketplace plugins, but it does not individually validate this repository package.

The repository documents Cowork and Claude Code use. Do not assume its CLI commands or local file workflows run unchanged in Duet.

Limitations to know about

The README describes a better experience with a data warehouse connection and a manual path (paste results or upload CSV and Excel files) without one. The manual path is the safer first test.
It is primarily designed for Cowork and also works in Claude Code. The README does not describe Duet.

Also: Start with read-only access. Check units, missing data and query cost; connector availability depends on your setup.

When it is not the right fit

The answer needs production database access and nobody can review the SQL it writes.
The dataset has no documented units, dates or definitions.

A small task to start with

This is our suggested evaluation prompt, not a tested result or an installation command.

Profile this CSV, identify missing values and explain which comparisons are valid before drawing a chart.

Use non-sensitive sample data first. Compare the answer with the original inputs and record what needed correction before expanding the workflow.

Before you rely on it

Begin with an uploaded CSV and no live database connection.
State units, time zones and reporting periods in the first message.
Run the validation command or ask for a methodology check before sharing any chart.

Where to get started

Read the upstream plugin source, dependencies and license.
In Claude, check Customize for the relevant skill or plugin. Follow the current official installation guide rather than guessing a Duet command.
Verify availability in your own environment and run a small, reversible task.
