A direct policy installed over a proxied one swapped the global dispatcher but left `process.env` holding the outer install's published normalization. `proxyEnvironmentForChild()` returns nothing under a direct policy, and `scrubbedParentEnv()` copies `process.env` as it is, so a child spawned in that window inherited values no active policy stood behind: an `HTTPS_PROXY` derived from `HTTP_PROXY` the user never set, or the loss of a SOCKS value they set for `curl` and this package had refused. The direct branch now writes the user's own values — the record the outermost install keeps — back into `process.env` for the window, and re-applies the outer install's published values when it ends. An install underneath that proxied nothing published nothing, so there is nothing to put back. Publishing and restoring share one `writeProxyEnv`; the empty-string special case it replaced was unreachable, since a resolved bypass list always carries the loopback entries and an accepted proxy URL is never empty. The nesting is reachable only from tests since the plugin was removed; the fix keeps the disposer symmetric for whoever layers installs next.
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It is built on an everything-is-a-plugin architecture and 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 in developer preview and 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.
