Tianyi Cui 评 Claude Code Mods，对比 DeepSeekHarness 的全插件架构

Congrats to the Claude Code team on shipping Mods! A cute way to make your agent harness extensible and customizable.

It's a nice convergence of ideas: in Claude Code, mods are just plugins; and @DeepSeekHarness has been built around rethinking the concept of plugins from the very beginning.

While a subset of Claude Code features are made available as mods, in @DeepSeekHarness everything is a plugin: models, tools, skills, sessions, sandboxes, filesystems, loops, orchestration, and UI are ALL implemented as plugins, and can be mixed, matched, replaced, and extended.

In @DeepSeekHarness's Creator Mode, you can prompt the agent to inspect the live runtime, write plugins, and persist them, in order to change the UI, modify agent-loop behavior and mechanisms, and add tools or new ways of orchestration — simply everything about the agent harness can be modified on the fly and persisted.

So we've been thinking about the term http://Plugin.Engineering for a while… Or should it be http://Mod.Engineering now? 😂
