DeepSeek Harness

DeepSeek Harness is a composable agent workbench for developers that provides code editing, terminal commands, planning, skills, model configuration and multi-agent collaboration. The Lazy Cat version saves settings, sessions, plug-ins and workspaces locally in the micro-service, and enables workspace write isolation and manual approval by default. - This application is only used by micro-service administrators because the agent has command execution and file modification capabilities. - There is no default account or password; access is protected by Lazy Cat Login Protection, and the administrator role is verified again. - Users configure the model API Key themselves, and credentials are managed by the upstream Harness's local credential store. - The upstream configuration interface originally only allowed localhost; this version makes a single-line adaptation with exact match protection during construction, allowing it to accept the trusted application domain name assigned by the lazy cat. The outer layer is still protected by both lazy cat login and administrator roles. - No logon-free paths or layer-4 ports are open. - The upstream is currently Developer Preview, and the application has been prompted to backup before upgrading. DeepSeek Harness is built on the Cordis plug-in system. All Agent capabilities such as models, tools, skills, sessions, sandboxes, storage, looping, scheduling, and UI are provided by plug-ins and collaborate with each other through Cordis services and events. Developers can select, replace, or extend any capability at the configuration level without changing the DeepSeek Harness source code. Every operation has a trace to follow Everything the model sees will be written to the appendance-only session log, including system prompt words, thought chains, tool calls and results, sub-agent scheduling, and each context injection. In the Trajectory view, you can view this information by source. Recovery, fork, retrieval and playback also share the same event stream. plurality of operating modes Standard mode provides a complete tool combination;PTC mode combines multiple rounds of tool calls through a piece of code generated by the model; Minimalist mode retains only one shell tool and one file editing tool for model benchmarking in a minimized environment; Creative mode can check the current runtime, test Cordis plug-ins in memory, and combine and create new modes accordingly.
