Skill use gemini to auto review

I built a Claude Code skill that uses Gemini to auto-review every plan before you approve it

Quick context: I use Claude Code heavily for client work and I was approving plans too fast — missing edge cases that only showed up later.

So I built this: a skill + hook combo that intercepts ExitPlanMode and pipes Claude’s plan to Gemini for an independent second opinion, automatically.

What Gemini reviews for:

∙	Missing steps or risks

∙	Edge cases not addressed

∙	Better implementation alternatives

∙	Architecture concerns

Models:

∙	gemini-2.5-flash-preview — default, fast, 1M context

∙	gemini-2.5-pro-preview — auto-switches for complex queries

Setup: 3 bash commands + one JSON config. MIT license.

Curious if other Gemini CLI users are building similar workflows — feels like the hook system opens up a lot.
