Zsh helpers for LLM Git diff review

AI Analysis
●MidShip It
Zsh wrapper around existing LLM APIs; Claude Code and Copilot already do diff review.
Strengths
- •Eliminates manual copy-paste of diffs into LLM interfaces, saving steps in review flow.
- •Supports multiple diff ranges (commits, staged, working tree, PR branches) with one-liner syntax.
- •Works with both Claude and Copilot CLI, providing flexibility for tool choice.
Weaknesses
- •Shell script wrapping existing APIs—no novel technical approach or functionality beyond convenience.
- •Narrow audience: requires Zsh, Claude Code CLI or Copilot CLI; many devs use IDEs with integrated review.
