AI Universe Second Opinion Workflow

Quick start: Use /secondo or the HTTPie helper script to gather multi-model analysis (Cerebras, Gemini, Perplexity, GPT-4o + synthesis).

---

Activation cues

• Requests to run or debug the AI Universe "second opinion" workflow.
• Follow-ups after failed /secondo runs or HTTPie 401/5xx errors.
• Planning sessions that need step-by-step instructions for MCP calls.
• Questions about cost, rate limits, or interpreting multi-model output.

Prerequisites & authentication

1. Verify auth-cli.mjs installation:

   test -f ~/.claude/scripts/auth-cli.mjs && echo "✅ Installed" || echo "❌ Not found - run /localexportcommands"
   

2. Check authentication status:

   node ~/.claude/scripts/auth-cli.mjs status
   

3. If not authenticated or token expired, run login (opens browser for OAuth):

   # Run this outside Claude Code in a regular terminal
   node ~/.claude/scripts/auth-cli.mjs login
   

4. Ensure http (HTTPie), jq, python3, and node (>=20.0.0) are installed in the environment.

ℹ️ Seamless Auto-Refresh: The /secondo command uses the exact same auth-cli.mjs from AI Universe repo. If your token is valid, it does nothing. If expired, it auto-refreshes using your refresh token (silent, no browser popup). Only prompts for login if refresh token expires (30+ days).

ℹ️ Token Location: All tokens stored in ~/.ai-universe/auth-token.json (same as AI Universe repo)

• ID token: 1-hour expiration
• Refresh token: enables 30+ day sessions

ℹ️ For a dedicated authentication walkthrough see ai-universe-auth.md. Dependency notes live in secondo-dependencies.md.

Primary commands

Scenario	Command
Quick question (when SlashCommand is working)	/secondo "Should I use Redis or in-memory caching?"
Build MCP request with PR context	python3 skills/second_opinion_workflow/scripts/build_second_opinion_request.py /tmp/mcp_request.json "QUESTION" 3 origin/main
Call MCP via HTTPie	http POST https://ai-universe-backend-dev-114133832173.us-central1.run.app/mcp "Authorization:Bearer $TOKEN" < /tmp/mcp_request.json --timeout=180 --print=b
Parse embedded JSON response	jq -r '.result.content[0].text' /tmp/mcp_response.json > /tmp/mcp_parsed.json
Summarize models/costs	python3 skills/second_opinion_workflow/scripts/parse_second_opinion.py /tmp/mcp_parsed.json
End-to-end helper	skills/second_opinion_workflow/scripts/request_second_opinion.sh "QUESTION" [MAX_OPINIONS]

Recommended workflow (HTTPie)

1. Generate the request payload (captures diff + per-file patches automatically):

   python3 skills/second_opinion_workflow/scripts/build_second_opinion_request.py \
     /tmp/mcp_request.json \
     "YOUR QUESTION HERE" \
     3 \
     origin/main
   

   Adjust SECOND_OPINION_MAX_FILES, SECOND_OPINION_MAX_DIFF_CHARS, or SECOND_OPINION_MAX_PATCH_CHARS if you need more/less context.
2. (Optional) Inspect/tweak /tmp/mcp_request.json to refine the natural-language question while keeping the attached git context intact.
3. Get authentication token (auto-refresh from AI Universe repo):

   # Get token (auto-refreshes if expired, does nothing if valid)
   TOKEN=$(node ~/.claude/scripts/auth-cli.mjs token)
   

4. Send request (allowing up to 180s for cold starts):

   http POST https://ai-universe-backend-dev-114133832173.us-central1.run.app/mcp \
     "Accept:application/json, text/event-stream" \
     "Authorization:Bearer $TOKEN" \
     < /tmp/mcp_request.json \
     --timeout=180 \
     --print=b > /tmp/mcp_response.json
   

5. Parse embedded JSON and display summary (or use the helper script):

   jq -r '.result.content[0].text' /tmp/mcp_response.json > /tmp/mcp_parsed.json
   python3 <<'PYEOF'
   import json
   with open('/tmp/mcp_parsed.json', 'r') as f:
       data = json.load(f)
   print(f"✅ Received responses from {data['summary']['totalModels']} models")
   print(f"? Total cost: ${data['summary']['totalCost']:.4f}")
   print(f"? Total tokens: {data['summary']['totalTokens']:,}")
   print("\nPrimary response:\n")
   print(data['primary']['response'])
   PYEOF
   

   Or run:

   python3 skills/second_opinion_workflow/scripts/parse_second_opinion.py /tmp/mcp_parsed.json
   

6. Review synthesis to confirm consensus and recommended actions.

SlashCommand fallback (Option A)

Use /secondo "QUESTION" for quick prompts only when the command file is healthy. If it fails or hangs, switch to the HTTPie workflow.

Automation helper script

Run the bundled script from repo root for a streamlined flow:

skills/second_opinion_workflow/scripts/request_second_opinion.sh "How should I harden our auth endpoints?" 4

The script:

1. Validates token presence and checks that MAX_OPINIONS is a positive integer.
2. Invokes build_second_opinion_request.py to embed branch/base metadata, diffstat, recent commits, and per-file patches into the payload.
3. Calls the MCP endpoint with HTTPie and a 180s timeout.
4. Parses the embedded JSON and prints model count, token usage, cost, and the primary + synthesis responses.
5. Writes raw artifacts to /tmp; set KEEP_TEMP_FILES=1 when running the script to keep them after completion.

For advanced prompting templates and interactive options, see the existing ~/.claude/scripts/secondo-cli.sh utility.

Troubleshooting

• 502 Bad Gateway / cold start → Retry after 30–60 seconds. Send a lightweight "What is 2+2?" request first to warm the backend.
• 401 Unauthorized / invalid token → Token expired (30-day TTL). Re-run node scripts/auth-cli.mjs login outside Claude Code.
• "command -c invalid" errors → Avoid nested command substitutions. Use heredocs + two-step token capture as shown above.
• Parsing failures → Always extract .result.content[0].text before loading JSON. Use the helper Python snippet or script for safe parsing.

Cost & rate limits

• Authenticated users: 100 requests/hour, with multi-model synthesis limited to 1/hr.
• Typical cost ranges: $0.01–$0.20 depending on prompt complexity.
• Model cost breakdown (approx.): Cerebras $0.003, Gemini 2.5 Flash $0.001, Perplexity $0.002, GPT-4o $0.10, synthesis $0.005.

Reporting expectations

• Confirm authentication status and whether /secondo or HTTPie path was used.
• Provide model count, total tokens, and total cost from the parsed summary.
• Include primary + synthesis takeaways or recommended next actions.
• Note any errors encountered and remediation steps (e.g., re-authentication, retries).
