Show HN: Crabby – Claude Code skill that reviews code like the Rust compiler

Crabby addresses a critical pain point in LLM-based code review: lack of structured, actionable feedback. By standardizing output to a `rustc`-like format, Crabby enhances developer trust and efficiency. The ability to apply this rigorous diagnostic approach beyond code to writing or strategy indicates a broader market for structured AI feedback. This moves beyond generic LLM responses, offering a template for integrating AI into existing developer workflows with high precision and immediate utility. The focus on "paste-able fix" directly targets developer productivity, reducing cognitive load and accelerating remediation cycles. This product exemplifies the trend of specialized AI agents providing domain-specific, actionable intelligence.
