DeepSeek Harness Just Exploded — What "Everything Is a Plugin" Really Means (Even the Loop Swaps)

Описание: One command — npx @deepseek-ai/dsh web — and a frontier lab's agent harness opens in your browser, MIT-licensed, free. Every video about it is saying the same sentence: everything is a plugin. That sentence is true. But the most interesting sentence in the launch is the one right next to it, in line one of the README — a credit almost everyone read past.

This is the source-level look at what actually shipped: the nine sockets that really swap (models, tools, skills, sessions, sandboxes, storage, LOOPS, scheduling, and the UI — yes, the reasoning loop itself is a package), the community kernel at the center and what "vendored" means, and the two features nobody is covering that happen to be the best two: an append-only flight recorder of everything the model ever saw — every prompt, every tool result, every context injection, inspectable by source, forkable, replayable — and Code mode, which ships the biggest argument in agent design this year as a button (the model writes ONE TypeScript program instead of forty JSON tool calls).

Plus the fine print at full volume: version 0.1 rc.5, a storage layer that keeps its format version at zero "with no compatibility promise" (their words), a genuinely impressive Landlock kernel-sandbox runner in the tree next to a local-execution default you should understand, the byte-budget AGENTS.md loading, the .claude folder in DeepSeek's own repo — and exactly who pays: the board is free; the vendor's newest chip arrives already seated in the socket.
