7. DSH Deep Whale

The Maid Atelier whale character skin restyles DSH Web with a themed character presentation. Deep Whale leaves the agent loop and coding tools unchanged.

FAQs

Are DeepSeek Harness plugins the same as Agent Skills?

No. Agent Skills contain instructions and optional helper scripts that guide an agent through a task. DSH plugins run inside the Harness plugin system and can add skills, tools, interface components, runtime services, memory, filesystems, models, and session behavior.

Does a high Star count make a community plugin safe?

No. Stars show public interest, while the package still runs with your user permissions. Inspect its source and installation scripts before granting access to important files, environment variables, subprocesses, or network credentials.

Why does this article use a 100-Star minimum?

The 100-Star minimum keeps this article short enough to scan. The public Awesome repository tracks the larger list of community plugins with 50 or more Stars every week.

How do I update or remove a DSH plugin?

Use the same profile that owns the installed package:

dsh plugin --profile web update package-name
dsh plugin --profile web remove package-name
