Post-rebase reconciliation of the two TUI lines that evolved in parallel: - header subtitle prefers the latest logged session title over the configured welcome; the process-local auto-title owns the whole terminal title while a logged session/title still wins through the suffixed form - footer keeps staging's model/cwd/usage/cache layout and gains master's context-percent segment; per-step usage dedup carries cache buckets - test harness only stubs the llm catalog when the test did not mount the real LlmService, and defaults the TUI clock to the real Date.now - the plugin-shaped /reload test composes commands+llm like the shipped app
DeepSeek Harness
English | 中文
The DeepSeek Harness SDK is a plugin-based SDK for building agent harnesses.
Install
Install the dsh coding agent with one line — it needs git and Node ^22.19 || >=24, and offers to install pnpm if it is missing:
curl -fsSL https://raw.githubusercontent.com/deepseek-harness/deepseek-harness/master/scripts/install.sh | sh
It clones the harness to ~/.dsh/source, runs pnpm install, symlinks dsh into ~/.local/bin (offering to add it to your PATH), prompts once for your DEEPSEEK_API_KEY, and launches dsh; re-running it updates an existing checkout. Run from inside a checkout (sh scripts/install.sh) it reuses that checkout and skips the clone. The overridable DSH_* variables are documented in scripts/install.sh.
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.
