Check a task by comparing it with another Claude chat

Claude Cowork can verify work from a separate Claude conversation before you hand it off.

Done with Claude CoworkClaude· Beginner· Jul 2026

What they did
The user kept one Claude conversation open in a browser and opened the same task in Claude Desktop’s CoWork mode. They then supplied CoWork with the browser chat link and allowed it to use the browser and local tools. CoWork was instructed to consult the other Claude session about the task’s questions, outputs, and recommendations before reporting back.
How it went
They said the two agents can trade notes until the rough edges are gone, which saves a lot of manual checking. In a later comment, they estimated it removes about 90% of the back-and-forth and works for almost every task.
Tips
A simple Claude Desktop CoWork setup and a chat URL were enough. Keep the agent in review mode and require your approval before any payment, submission, or other irreversible step.

Try it yourself with Claude Cowork

I’m giving you a Claude chat URL for work I already did: [chat URL]. Review that conversation as a separate checker. Verify the facts, calculations, and logic; call out anything unclear, missing, or unsupported; and, if needed, ask the other Claude session follow-up questions before you answer. Give me a short list of problems and fixes, and do not send, submit, delete, pay, or change anything until I say so.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
