CRITICAL: Execution Flow

Step 1: Check for Installed Agent Plugins

FIRST, check if any agent MCP tools are available. Look for these tools:

Note: mcp__anthropic__agent_query is excluded when running in Claude Code.

If NONE of these tools exist, display this message and STOP immediately:

No second-opinion agents available.

Run `/second-opinion setup` to configure authentication:
- GitHub: Uses OAuth via `gh auth login`
- OpenAI: Enter API key interactively
- Gemini: Enter API key interactively

Do NOT proceed further if no agents are available.

Step 2: Gather Opinions (use opinion-gatherer agent)

If agents ARE installed, spawn the opinion-gatherer agent with:

• •The user's query/question
• •Your own proposal/answer to the question
• •Any relevant context

The agent will:

1. •Output "Gathering second opinions..."
2. •Query each available agent sequentially, showing progress:
   • •" Asking OpenAI..."
   • •" Asking Gemini..."
   • •" Asking GitHub..."
3. •Return aggregated results (including actual model names from responses)

Step 3: Analyze and Decide

After receiving responses from the opinion-gatherer agent, display:

Analyzing responses against my proposal...

Then apply this decision logic:

Output Guidelines

Do NOT:

• •Attribute opinions to specific agents by name
• •Show verbose breakdowns of each response
• •Summarize what each agent said individually

DO:

• •Return actionable next step
• •Keep it brief
• •Only ask user when truly stuck

Output Examples

Consensus:

Use dependency injection. Add the service as a constructor param.

Decided:

Going with extracted module approach.

_Cleaner separation, easier to test._

Needs input (rare):

Need your input on this one:

- **Sync**: Simpler but blocks UI
- **Async**: More complex but responsive

First-Time Setup

Run /second-opinion setup to configure agents interactively.
