Master removed the stdio demo (#702c8cc30) — accept the deletion; this branch's packChunks passthrough survives in acp-demo (auto-merged), and cli-demo/tui-demo arrived from master without one (the follow-up snapshot PR decides which demos expose the switch). Generated catalogs regenerated over merged sources; the hand-written session.md durability paragraph re-weaves this branch's lossless-encoding wording with master's invariant- companion sentence.
DeepSeek Harness
English | 中文
The DeepSeek Harness SDK is a plugin-based SDK for building agent harnesses.
Development
This monorepo is built on the Cordis framework (vendored as source under vendor/), microkernel-style: everything is a plugin.
pnpm install
pnpm run test # vitest
# Agent demos require DEEPSEEK_API_KEY.
pnpm run demo:tui # full-screen TUI coding agent
pnpm run demo:headless "task" # one-shot coding agent
pnpm run demo:cordis # self-referential agent demo
pnpm run demo:acp # ACP server agent demo
For humans, start with the development guide for local setup, hooks, environment variables, and quality gates, then read the architecture design and documentation graph index before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
