The collapse read as a hard cut: only the track width animated while the panel content swapped instantly and the rail icons bore no relation to the expanded layout. Now the four control rows persist across the transition — collapse toggle, new session, new workspace, search, the same top-down order as their expanded rows — and morph their geometry (row heights, paddings, margins, capsule borders) on the deepsuite curve, so each rail icon is its expanded control converging onto the 56px axis. Wide-only content (brand, labels, input, session tree) cross-fades over 200ms, stays mounted while the collapse animates, and unmounts at the 300ms settle, still dropping the sessions subscription. The search query moves up to the root and survives the round trip; rail search focuses the surviving input after expand instead of remount-autofocus.
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.
