Gemini Advisor Skill
Before Starting
- Check Gemini availability — Run
test -n "$GEMINI_API_KEY" via Bash to verify
the API key is configured. If it fails, inform the user that Gemini API key is not
configured and offer to answer the question directly.
- Determine context — Figure out what the user wants Gemini's opinion on:
- A specific file → read the file content
- A code question → formulate the question with relevant context
- A discussion/decision → summarize the current discussion state
- A general topic → pass the question directly
Process
Step 1: Prepare the Query
Build a clear, self-contained prompt for Gemini that includes:
- The user's question or topic
- Relevant context (file contents, discussion summary, code snippets)
- Framing: "Provide your independent technical opinion on the following."
Step 2: Send to Gemini
Use Bash to invoke the Gemini API entrypoint:
echo "<context>" | node {pluginDir}/dist/gemini/cli.js --prompt "<question with framing>"
Or without stdin if no file/code context is needed:
node {pluginDir}/dist/gemini/cli.js --prompt "<full question with context>"
The CLI outputs JSON with success, output, model, and optional error fields.
Step 3: Present Results
Output Format
Gemini's Take
[Gemini's full response, formatted cleanly]
Claude's Commentary
[Brief commentary on Gemini's response — agreements, disagreements,
additional considerations, or alternative perspectives. Keep this
concise — the point is to get a second opinion, not to debate.]
Fallback Behavior
If Gemini API key is not configured or the call fails:
- Inform the user: "Gemini API key not configured."
- Offer to answer the question directly as Claude.
- Do NOT block on Gemini unavailability.
Guidelines
- Present Gemini's output faithfully — do not rewrite or censor it.
- Claude's commentary should be brief and additive, not defensive.
- If the user's question is about a file, always read and pipe the file content.
- Keep Gemini prompts self-contained — Gemini has no conversation context.
- Do not send sensitive information (secrets, credentials) to Gemini.
When to Use This Skill
Use gemini-advisor for second opinions on any topic, file, or technical question. Use gemini-reviewer (/gemini-review) for structured dual code reviews with formal synthesis and verdict.
