DeepSeek Harness, a plugin-first agent runtime
Credibility concern recorded. The source reference remains available for verification and correction.
A developer preview of a local agent runtime with swappable plugins, several execution modes, and a browser interface on port 3080.
Field notes
The runtime is presented as a Cordis-based system in which models, tools, sessions, sandboxes, storage, scheduling, and the UI can be installed or recomposed as plugins. Its four described modes range from a minimal shell-and-editor setup to Creator mode for experimenting with plugins and authoring presets. Runs are recorded in an append-only event stream supporting resume, fork, search, and replay. The page identifies version 0.1.2-rc.1 and a local interface at 127.0.0.1:3080.
