Independent review
Is DeepSeek Harness ready for your project?
The architecture is highly composable, but developer-preview status makes version discipline and source verification essential.
What stands out
Models, tools, skills, sessions, and sandboxes share a plugin-oriented composition model. This reduces permanent core patches and makes experiments easier to reverse.
Current limitations
APIs and documentation can change quickly. Compatibility, migration cost, ecosystem quality, and runtime behavior should be verified against a specific release.
Who should try it
It fits developers exploring agent runtimes and extension architecture. Teams needing a stable production contract should run a bounded evaluation first.
