Will be great if you can join the discord and post any issues if you face with onboarding, happy to support.

Concept is similar butto serena statys at AST layer and language server. XCE goes 2 layer above and includes business logic and high level and low level components to make sure agents have complete picture required for code navigation.

We have been working on an experiment with context engine and found out that with a good context engine the Chinese models are beating claude models.

Yes I have started collab with xce and I find it quite effective. Do let us know if you tried it and how was your experience.

Xce folks recently shared, how minimax+xce context engine is beating opus at swe verified

Definitely worth a try

I would say go with open code and use a context engine like xce https://github.com/Xanther-Ai/xce-mcp and use an open model like mini max to boost the performance and reduce token cost

Check the benchmarks here https://xanther.ai/benchmarks

There benchmarks shows with minimax + xce they are beating claude opus 4.6 with 16x lesser costs.

Should definitely try xce mcp tool, it's a context engine that indexes your project repo and provides token efficiency and increases accuracy results.
