dsh-ecc

Everything Claude Code has built a mature set of agent personas, skill definitions, and model reasoning catalogs, but those surfaces are tightly coupled to the Claude Code runtime and cannot be dropped into another framework as-is. dsh-ecc acts as an adapter layer that brings ECC core runtime surfaces into DeepSeek Harness, without modifying the DSH core and without replacing Claude Code, so both ecosystems keep their own value independently.

The plugin delivers three core capabilities. First, ECC agent Markdown files are injected as persona and instruction resources for child agents, with the child inheriting the parent effective DSH tool scope. Second, ECC skill bodies are loaded through the DSH native skill registry, supporting flat kebab-case discovery and invocation. Third, a model / provider / reasoning-effort catalog is injected via DSH lifecycle hooks, enabling spawn and spawn_fork to select an explicit model and conditionally attach or omit the reasoningEffort field, with durable follow-up and cold-resume support.

It is aimed at developers working in DeepSeek Harness who want to leverage ECC agent personas and skills, particularly those who need structured child-agent workflows where spawn_fork seeds a child from the parent session's completed turns. The plugin ships with a pinned ECC commit snapshot, does not depend on upstream tags, and supports clean rollback to a previous known-good release.
