Installation
SKILL.md
Use Gemini to get an independent review from a model with a 1M+ token context window.
Use -p for non-interactive (headless) mode. Always use -o text for plain text output.
Prefer telling Gemini to read files directly over piping via stdin. Gemini can read files within the project workspace on its own, and stdin truncates at 8MB.
