The packaged dsh launcher must expose installation modules to profile-local plugins without writing symlinks into pkg's virtual filesystem. The first review fix selected ESM exports correctly in ordinary Node, but real carrier execution exposed package metadata and VFS behavior that a synthetic tree did not cover: executable and declaration packages have no import entry, legacy main fields rely on Node probing, and pkg's Windows VFS prevents filesystem package-scope resolution from seeing exports such as zod/mini and @google/genai/web. Resolve explicit exports directly from each installed manifest with the maintained resolve.exports package under Node import conditions. Publish only package-local candidate files that exist, reject escaping or malformed targets, preserve the package installation URL without realpath, and keep Node's legacy resolver only for exports-less packages. This avoids pkg filesystem package lookup entirely while retaining fail-loud behavior for broken runtime entries. Add regression coverage for import-only, nested, symlinked, zod-style, and genai-style condition maps; unavailable and types-only entries; invalid and escaping targets; executable/declaration packages; extensionless main; and legacy index fallback. profile.ts remains at 100% statements, branches, functions, and lines. Update the bilingual package and Agent Note contracts, replace the runtime dependency and generated notice, and regenerate the lockfile through pnpm.
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It uses an architecture where everything is a plugin, and is powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.
Documentation: https://deepseek-harness.github.io/deepseek-harness/
Developer preview
DeepSeek Harness is currently in developer preview and is iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
Review the safety notice before running the project.
Run
Run from npm
Install Node.js, then run:
npx @deepseek-ai/dsh web
The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch. An SSH launch only prints the host URL because the SSH client or editor owns the local forwarded address. Pass --no-open to run the server without opening a browser. See Web UI guide.
Run from source
To run from a repository checkout:
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
