Python packages for driving DeepSeek Harness as a subprocess. The client SDK communicates with the bundled runtime over newline-delimited JSON-RPC on stdio.

Packages

DirectoryDist / moduleRole
sdkdeepseek-harness-sdk / deepseek_harnessHigh-level turns API and lower-level JSON-RPC client
sdk-runtimedeepseek-harness-runtime-bin / deepseek_harness_runtimeBundled dsh CLI executable and native sidecars

Behavior

The SDK starts the matching bundled dsh --profile sdk runtime unless the caller selects another dsh executable or profile. The runnable minimal example selects the shipped standalone sdk-minimal profile; the same runtime also packages dsh web and its frontend assets for separate CLI use. Every launch requires an explicitly selected Harness home; Python never silently reads ~/.dsh. The SDK reference and runtime carrier reference own runtime selection, profiles, patches, and external plugin management.

Contributor workflows

The Python contributor workflows cover building runtime artifacts, validating the packages, source-mode development, and distribution.
