Maintainers spend hours every week closing duplicate issues. 😮‍💨 That changes with duplicate detection. Surface up to 3 matching issues as you create one, before you hit submit.

Great feature! This should significantly cut down on maintainer burnout. Any plans to make the similarity threshold adjustable or add it to the API for custom workflows?

An AI agent to manage your security and infrastructure? Yes, we already have one. This is V2, and it is a different machine. Smarter reasoning, faster responses, a cleaner interface, and it now costs 80% less to run.

Works until people just type "bug" and hit submit anyway 🤷

Can't wait for users to ignore 3 matching issues and hit submit anyway. 🤷

Works for regular bugs, but the good duplicates always use completely different words 🤷

Now they can ignore three matching issues instead of zero 🤷

Works until someone describes the exact same bug in three completely different ways 🤷

Catching duplicates before submit is probably the least annoying way to keep a repo clean.

Duplicate issue detection before submit is the kind of developer workflow improvement that seems small but saves thousands of hours across the ecosystem. The real test is whether it catches semantic duplicates where the wording is different but the underlying bug is the same.
