Kimi K3 Real-World Test: Strong Cross-File Analysis, but the Final Plan Still Needs Human Review
I tested Kimi K3 Max on a real Astro project and added the subscription pause, Kimi Code 0.26/0.27/0.28 changes, the 1M-context plan requirement, and model-switch cache behavior. Its cross-file analysis is strong, but production decisions still need human review.
