The pre-join check charged the whole unframed buffer, which legitimately holds several frames each within FRAME_PARSE_CAP_BYTES: a first frame of exactly the cap followed by a second frame crossed the counter and was misreported as a worker-exit. The pre-join rejection now fires only while the held bytes are a single unframed line (this chunk carries no newline); once a newline arrives, a FIRST-FRAME check measures the bytes up to the first newline across the held chunks (including sealed blocks) and rejects only that frame before the join — keeping the peak at one copy of its wire bytes — while later frames in the same buffer are handled by the restored per-line check. Regression cases: a 72 MiB newline-free buffer is rejected pre-join (fail-before: joining would have doubled it); two within-cap frames whose combined buffer crosses the cap both survive (fail-before: the unconditional counter check turns it red).
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.
