Kotro Open-Source Rust Proxy Slashes AI Coding Costs

Kotro is an open-source Rust sidecar that intercepts IDE LLM traffic to cut token usage and prevent runaway costs. It features a circuit breaker to stop infinite error loops, local routing for trivial prompts, and AST-aware pruning to reduce tokens by 50%. The tool also uses vector semantic caching to avoid redundant API calls, aiming to solve the AI productivity paradox.
