gemini-second-opinion

仅适用于非Gemini代理（Claude、Codex）。当面临存在不确定权衡或多种可行方案的决策时，自动调用Gemini CLI，在后台运行以获取第二意见。Gemini代理则应改用claude-second-opinion。

name: gemini-second-opinion
description: "For non-Gemini agents only (Claude, Codex). Invoke automatically when facing a decision with uncertain trade-offs or multiple viable options. Runs Gemini CLI in the background to get a second opinion. Gemini agents must use claude-second-opinion instead."

Gemini Second Opinion

Get an alternative perspective from Gemini on any decision, design, or code.

Task

  1. •

    Self-Check (CRITICAL):

    • •Are you acting as a Gemini agent?
    • •If YES: STOP IMMEDIATELY. Do not proceed. Consulting yourself is redundant and wasteful. Report to the user that you cannot use this skill as a Gemini agent.
    • •If NO (e.g., you are Claude): Proceed to step 1.
  2. •

    Gather the context for the second opinion:

    • •If $ARGUMENTS contains a specific question, use it as-is
    • •If working on code, include relevant file contents or diff
    • •If evaluating a design decision, summarize the options being considered
  3. •

    Construct a prompt and run Gemini CLI:

    bash
    gemini -p "<constructed prompt>" -o text
  4. •

    Run Gemini CLI using environment-specific handling:

    • •If running in Codex CLI (long-running-safe flow):
      1. •Start Gemini in background and capture logs to a temp file.
      2. •Save PID and poll every 10-15 seconds.
      3. •Use a hard timeout (default: 300 seconds).
      4. •If timeout is hit, report that Gemini is still running and include the latest log tail (do not block indefinitely).
      5. •If process exits non-zero, report failure and include stderr/log tail.
    • •Otherwise: run synchronously and wait for result
  5. •

    Present Gemini's response alongside your own analysis, highlighting agreements and disagreements

Prompt Construction

Wrap the context and question for Gemini as follows:

code
You are providing a second opinion on a technical decision.

Context:
<context from the current task>

Question:
<the specific question or decision point>

Provide your independent analysis. If you disagree with the current approach, explain why and suggest alternatives.

Rules

  • •Gemini Agent Restriction: DO NOT activate or use this skill if you are already a Gemini model. Consulting yourself is redundant. This skill is intended for non-Gemini agents (like Claude) to get a Gemini perspective.
  • •Always present both your perspective and Gemini's perspective
  • •Clearly label which opinion comes from which model
  • •If Gemini's response contradicts yours, explain the trade-offs of each approach
  • •Do NOT blindly adopt Gemini's suggestion - evaluate it critically
  • •Keep the Gemini prompt focused and under 2000 characters for reliability
  • •In Codex CLI, always provide progress updates while polling and avoid silent waits longer than 15 seconds
  • •In Codex CLI, do not lose intermediate output: preserve and summarize partial logs on timeout/error
