Been using it for a while, now all other tools feel lacking. The multistep process with manual refinement options after every step just works so much better for keeping LLMs in line. The only times I’ve used anything but kiro since, has been when the Sonnet 4.0 was once again overloaded (tried it with 3.7 for a bit, but it went way off the rails of kiro’s tasks structure every time).
