- workspace-context: a transiently unavailable but still-effective candidate keeps its cached trimmed digest in the directory's dedup slot, so an identical later sibling is not emitted as a duplicate set until the next successful reconciliation - app-boot: --resume rejects a following token that is itself resume syntax instead of accepting it as a session id - tui: the queued-steering badge tracks per-entry sources and a drain removes one matching entry, so loop-authored steering (no agent/queued) cannot consume a pending user message's slot
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.
