name	gemini-critic
description	Ask Gemini's most powerful model for an independent second opinion - critique code with fresh eyes, evaluate an article, challenge a plan. The calling agent controls the exact question and material; this skill just executes the call and returns Gemini's answer verbatim.

Gemini Critic

ℹ️ First, set expectations: before anything else, print one short line with this skill's version and its most recent change - the top entry of metadata.changelog above - e.g. gemini-critic vX.Y — recent: <summary>. Then proceed.

Purpose

Get a genuinely independent second opinion from a different frontier model. The caller (Eugene or another agent/skill) decides what to ask and what material to send - review this diff, tear apart this article, find holes in this plan. This skill is a pure executor: assemble the payload, call Gemini, return the answer verbatim. It never answers the question itself, never softens or summarizes the critique, and never acts on the critique's suggestions.

State Dependencies

Source	Location	Read	Write
Gemini API (primary)	bundled scripts/ask_gemini.py (direct REST call)	-	sends prompt + material
API key	GEMINI_API_KEY env var	yes	never
Gemini API (fallback)	mcp__aistudio__generate_content MCP tool, if connected	-	sends prompt + material
Input material	file paths supplied by the caller	yes	never

The skill is self-contained: the bundled script + key file work in any project on this machine, with no MCP server configured. Only transient prompt files are written (to the session scratchpad). No state persists between invocations.

The Executor Contract

These rules are what make the second opinion worth having - breaking them defeats the skill's purpose:

1. The caller's framing wins. Send the caller's question/instruction as given. Do not rephrase it, add your own concerns to it, or narrow its scope.
2. Return the answer verbatim. No summarizing, no filtering, no "Gemini mostly agrees with me". The calling agent judges the critique, not you.
3. Do not act on the critique. No edits, no fixes, no follow-up calls. Deliver the answer; your job ends there.
4. Fail loud, never degrade silently. If the MCP tool is unavailable, a file is missing, or the material is too large - stop and say exactly what's wrong. Never send a partial payload without flagging it.
