As AI coding assistants like Codex, Claude Code, Qoder, and OpenCode gain traction, developers often find themselves juggling multiple tools, resulting in fragmented configuration signals and session histories scattered across platforms. Managing this data separately can be inefficient and error-prone. The DeepSeek Harness External Migration plugin tackles this challenge by facilitating the safe and streamlined transfer of external agent data into DeepSeek Harness.

The plugin's core capabilities revolve around a comprehensive migration toolkit. It begins with external_migration_scan for a read-only inventory, allowing users to assess what can be migrated. Next, external_migration_preview provides detailed previews to ensure data accuracy before proceeding. Finally, external_migration_import executes the import with user confirmation, writing native sessions into Harness while exporting a reviewable configuration bundle. Crucially, source files are never modified, credentials are never copied, and MCP secrets are replaced with environment-variable references, ensuring high security and traceability.

This plugin is ideal for developers who rely on multiple AI coding assistants or wish to consolidate their configurations and histories into DeepSeek Harness for centralized management. Whether you are transitioning from a specific tool like Codex or integrating data from various sources to streamline your workflow, it offers a reliable and secure solution that simplifies the migration process while maintaining data integrity.
