Tianyi Cui 548bbe7ae8 docs(tui): record dedicated terminal front-door decision
Record the July 17 package split as an implemented bilingual feature RFC. The decision explains why TUI and stdio have separate terminal contracts, why concrete front-door selection belongs to composition, and how the TUI preserves existing session, tool-presentation, and lifecycle ownership.

Link the deterministic dark, light, and animated demos from the RFC so the assets have an in-repository owner. Cross-link the feature and testing decisions from the package README, then regenerate the RFC index and bilingual consistency record.

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
pnpm run demo:echo     # keyless mock-model REPL
pnpm run demo:repl     # readline coding agent (needs DEEPSEEK_API_KEY)
pnpm run demo:tui      # full-screen TUI coding agent (needs DEEPSEEK_API_KEY)
pnpm run demo:cordis   # self-referential agent demo (needs DEEPSEEK_API_KEY)
pnpm run demo:acp      # ACP server agent demo (needs DEEPSEEK_API_KEY)

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.
