Second Opinion Setup

Interactive configuration for second-opinion agents. No file editing required.

Authentication Methods

Agent	Auth Method	How to Set Up
GitHub	OAuth via gh CLI	Run `gh auth login` in terminal
OpenAI	API Key	Enter interactively below
Gemini	API Key	Enter interactively below

Instructions

Step 1: Check GitHub Authentication

First, check if gh auth token returns a token:

bash

gh auth token 2>/dev/null && echo "authenticated" || echo "not authenticated"

If authenticated: GitHub agent is ready to use (OAuth - no API key needed).

If not authenticated: Tell the user:

code

GitHub uses OAuth authentication.

To set up, run this in your terminal:
  gh auth login

Then restart Claude Code.

Step 2: Check for Existing API Keys

Read .claude/second-opinion.json if it exists to see what's already configured.

Display current status:

code

## Current Configuration

| Agent | Status |
|-------|--------|
| GitHub | ✓ authenticated via gh CLI |
| OpenAI | ✗ not configured |
| Gemini | ✗ not configured |

Step 3: Prompt for Missing API Keys

For each agent WITHOUT a configured key, use AskUserQuestion:

json

{
  "questions": [{
    "question": "Would you like to configure OpenAI?",
    "header": "OpenAI",
    "multiSelect": false,
    "options": [
      {"label": "Yes, enter API key", "description": "I have an OpenAI API key ready"},
      {"label": "Skip for now", "description": "I'll configure this later"}
    ]
  }]
}

If user selects "Yes, enter API key":

Use AskUserQuestion with a text input option:

json

{
  "questions": [{
    "question": "Enter your OpenAI API key (starts with sk-):",
    "header": "API Key",
    "multiSelect": false,
    "options": [
      {"label": "I'll paste it", "description": "The API key will be stored locally in .claude/second-opinion.json"}
    ]
  }]
}

When the user provides the key via "Other" input, save it to the config file.

Step 4: Save Configuration

Write the API keys to .claude/second-opinion.json:

json

{
  "apiKeys": {
    "openai": "sk-...",
    "gemini": "AI..."
  },
  "updatedAt": "2026-01-17T12:00:00Z"
}

Use the Write tool to create/update this file.

Step 5: Show Confirmation

code

## Configuration Complete

| Agent | Status | Auth Source |
|-------|--------|-------------|
| GitHub | ✓ ready | gh CLI (OAuth) |
| OpenAI | ✓ ready | stored locally |
| Gemini | ✗ skipped | - |

**Config file:** .claude/second-opinion.json

### Next Steps

- Use `/second-opinion` to get second opinions
- Run `/second-opinion setup` again to reconfigure
- GitHub auth: run `gh auth login` in terminal

### Security Note

API keys are stored locally in your project's `.claude/` directory.
Add `.claude/second-opinion.json` to `.gitignore` to avoid committing keys.

Important Rules

•NEVER ask users to edit files manually
•NEVER ask users to set environment variables
•Use AskUserQuestion for ALL user input
•GitHub uses OAuth via gh auth login - no API key needed
•Store API keys in .claude/second-opinion.json using Write tool
•Add reminder about .gitignore for security
