## What it is
DuckDuckGo's Instant Answer infrastructure (DuckDuckHack), a Perl-based platform for building instant answer plugins that display rich results on DuckDuckGo search. The project entered maintenance mode in 2015 and the repository is now archived and unmaintained.

## Use cases
- build instant answer plugins for duckduckgo search
- understand how duckduckgo instant answers worked
- fork the duckduckhack platform for a custom search engine
- study perl-based search result extension architecture
- contribute spice or goodie instant answers historically

## When to choose
- you need to study or fork the historical DuckDuckHack instant answer platform
- you maintain a legacy Perl instant answer integration

## When to avoid
- you want to build instant answers for DuckDuckGo today - the platform is archived and unsupported
- you need a maintained search extension framework
- you want to report DuckDuckGo bugs or suggest features - use the site's Feedback button instead
