Both ds-review-bot criticals verified and fixed: - ClientActivityFeed release closures resolved the entries map at release time, not the entry they were minted for. A late release of a superseded observation decremented (and could tear down) the successor's stream, and the post-dispose model clear could land after a re-observation inside the dispose round-trip re-anchored the view — blanking the panel until the popover reopened (React StrictMode's double effect hits the same window). Releasers now capture their entry, reconcile the map only when it still holds that entry, and skip the view clear whenever a successor owns the key. Both regressions fail on the previous code. - The background observation tap mapped the process outcome as soon as the pump settled — including its failure path, where the process is usually still running: processOutcome requires a settled handle, so an early mapping froze 'exit code: 0' onto a live task and first-wins end discarded the real terminal state. The tap now awaits proc.done before mapping (the promise never rejects) and swallows mapping failures per the module's contract, in bash and its pwsh mirror. Also applied from the same review: the Remote tier's cross-session visibility is now stated in the controller README, ActivityRead.next documents its chunk-boundary nature that client concatenation relies on, mergeRows records the one-activity-per-job assumption, and the 08-24 Agent Note now reflects the shipped unified task list.
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.
Community and support
- Feel free to submit feedback or bug reports through GitHub Discussions.
- Add the
dsh-plugintopic to your plugin repository for discoverability. - Join DeepSeek Harness Discord community.
