peepshow for agents / gemini

Gemini CLI—Custom extension + GEMINI.md instruction file.

`gemini-extension.json` registers peepshow as a custom tool; `GEMINI.md` tells the model when to reach for it.

How it plugs in

Gemini CLI supports custom extensions via a manifest file. peepshow ships `gemini-extension.json` so Gemini can invoke it like a tool, and `GEMINI.md` provides in-context instructions for when to use it.

Install

git clone --depth 1 https://github.com/t0mtaylor/peepshow.git
cd peepshow
gemini --extension .  # or add to your global extensions directory

All 19 sinks still work

The CLI is the same across agents — which means every sink documented under/sinksis available here. Auto-sinks fire regardless of which agent invoked peepshow.
