Finance & accounting plugin: Claude Duet status

Does Finance & accounting work with Claude Duet?

Not verified. Finance & accounting 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.

Source caveat

This plugin assists with finance and accounting workflows but does not provide financial, tax, or audit advice.

Limitations to know about

The README states that all outputs should be reviewed by qualified financial professionals before use in financial reporting, regulatory filings or audit documentation.
It is primarily designed for Cowork and also works in Claude Code. Do not read that as a statement about Duet.

Also: Not financial, tax or audit advice. Qualified professionals should review outputs before reporting or filing.

When it is not the right fit

You need filings or audit sign-off, which the README says qualified professionals must review.
Your ledger access cannot be limited to read-only.

A small task to start with

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

Compare these two balance exports. List reconciling items with source rows and leave unexplained differences open.

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

Use exports you can afford to share rather than live ledger access for a first test.
Have the person responsible for the books review every journal entry it prepares.
Record which outputs were machine-prepared so reviewers know where to look harder.

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.
