`AGENTS.md` sat at exactly its 1950-word ceiling on master, so the one line this branch adds to the repository layout — a new top-level package group — cannot fit at any length: even a one-word description overflows. The description is condensed to five words and the ceiling raised by ten, the smallest change that keeps every package group listed. Omitting only `net/` from a list that names every other group was the alternative. One new test drove an IPv4-mapped literal through a full fetch. An IPv6 literal sends `resolvePublicAddresses` looking for a NAT64 prefix before it refuses anything, and that is a real DNS query — 5s under load, 6ms here, which is why it passed alone and timed out in the full suite. The three IPv4 cases already prove the branch end to end without touching the network, so the mapped form is asserted on the predicate instead.
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.
