Product Positioning & Context
AI Executive Synthesis
Reviews code and other text like the Rust compiler, providing precise diagnostics in `rustc` error format with paste-able fixes.
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.
I built a Claude Code skill called crabby that makes Claude output diagnostics in rustc error format - severity codes, location arrows, causation spans, and a paste-able fix every time. The twist: Claude becomes Ferris the crab, grumpy and unimpressed, but technically precise.The format works for code review, writing review, architecture, strategy - anything you submit. The "writing review" example tends to surprise people: it flags passive voice in a postmortem with the exact same error[W002] format as a SQL injection.https://github.com/ekadetov/crabby
