A closed sidebar previously resolved to a zero-width grid track, clipping the only toggle and the settings entry with no visible recovery; the closed preference persisted across reloads, locking the sidebar shut. - columns.ts maps the closed preference (width 0) to a fixed 60px SIDEBAR_COLLAPSED rail through every step of the concession solve; closed details still resolve to zero width. - AppFrame derives data-sidebar-collapsed and the sidebar slot's collapsed owner prop from the persisted preference instead of the resolved track width, and drops the resize handle while collapsed. - SidebarRoot reads the owner collapsed prop; the expanded-only body is a separate component that unmounts while collapsed (dropping its sessions subscription), leaving the expand toggle and Settings in the rail. - The keyless web smoke gains the ui-sidebar bundle (six real bundles) and pins the 60px rail collapse/expand round through the assembled client.
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.
