dsh-cordis

Integrating the DeepSeek Harness coding engine into a Cordis-based host typically means standing up a separate runtime, scattering assembly details across application code, or coupling engine logic into the host through global singletons. dsh-cordis collapses that complexity into a single Cordis plugin: it mounts the full DSH composition—native agents, durable sessions, model adapters, tools, goals, plan mode, approvals, and packaged agent presets—directly into the host's existing Loader tree, without constructing a second root or introducing another event bus or lifecycle framework.

Consumers simply inject the service contracts they need (sessions, agents, tools, approvals, etc.) rather than importing concrete provider implementations. The engine acts as a capability seam: a host can observe, replace, or withdraw the DSH provider while downstream consumers remain untouched. Removing the Loader row immediately retracts the live services, moves the host into PENDING, and lets another provider take over—leaving no residual references or duplicate registrations.

The package deliberately keeps its public boundary small while carrying substantial depth behind it: it absorbs DSH composition, dependency resolution, and lifecycle mechanics, exposing callers to a compact, service-oriented surface rather than a bag of setup details. Configuration is composition—swapping a Loader row changes the deployment choice without threading provider switches through application code. It suits teams and independent developers who already build on Cordis, want to reuse DSH coding capabilities through the standard plugin channel, and require reversible replacement, contained failure, and clean separation from the rest of their host architecture.
