dsh-schematic

In DeepSeek Harness, an entire agent product is composed from plugins: the model adapter, the tool registry, and the agent loop all hang off Cordis context services and typed events. That wiring lives only inside the running process, and understanding who provides what, which events flow where, and how long each stage takes has meant grepping source or sprinkling logs. dsh-schematic draws that hidden wiring into an interactive topology graph and lets you edit it on the graph itself.

Open /schematic and you get three views (journey, domain mesh, table) that mirror the mounted plugin tree in real time. Every tool call and model reply is attributed to its owning plugin, the graph lights up as work flows, and a timeline records who did what and for how long. The v0.3.0 composition workbench turns the view from read-only to editable: toggle plugins, revise configs, swap a seam provider across local, sandbox, or remote scopes. All changes preview as ghost nodes plus a line-level YAML diff, pass a dry-run composition check, land in a versioned managed block, and hot-reload with one-click rollback.

Built for developers and operators who compose multi-plugin agent products on DeepSeek Harness and want to inspect the wiring without a debugger and adjust orchestration safely without taking the service down.
