DSH plug-in development tool
DeepSeek Harness External Migration Safely migrate configuration signals and session history from Codex, Claude Code, Qoder ( is accepted as an alias), and OpenCode into DeepSeek H.
Project overview
Safely migrate configuration signals and session history from Codex, Claude Code, Qoder (qcoder is accepted as an alias), and OpenCode into DeepSeek Harness.
The plugin provides three model-facing tools: externalmigrationscan: read-only inventory; no transcript bodies, no returned credentials, and no writes. externalmigrationpreview: read-only parsing with short transcript previews. externalmigrationimport: requires confirm=true, writes native Harness sessions, and exports a reviewable configuration bundle.
Source files are never modified. Credentials are never copied. MCP secrets are replaced with environment-variable references, and generated MCP configuration is not applied automatically. Install
