Squishling

Squishling is a Ruby gem and framework that lets developers route method calls to a large language model (LLM) fallback when existing Ruby code paths are not maintained or fail. It validates LLM output against strict schemas ensuring consistent typed results, enabling developers to 'squish' low-volume or complex code paths to AI and retain Ruby code for high-volume or critical operations. It supports multiple LLM providers, fallback model escalation, and usage cost measurement to optimize technical debt and maintenance effort.
