Clara Answers — Automation Pipeline

Demo Call → Retell Agent Draft → Onboarding Updates → Agent Revision

A zero-cost, end-to-end automation pipeline that ingests call transcripts and generates structured account memos + Retell AI agent configurations — with full versioning (v1 → v2) and changelogs.

Quick Start (5 minutes)

1. Clone & Install

git clone https://github.com/YOUR_USERNAME/clara-pipeline.git
cd clara-pipeline
pip install -r requirements.txt

2. Set Your Groq API Key

export GROQ_API_KEY=your_groq_api_key_here

Get a free key at: https://console.groq.com (no credit card, 1000 req/day free)

3. Add Transcripts

Place your transcript .txt files in:

• transcripts/demo/ → name them demo_001.txt through demo_005.txt
• transcripts/onboarding/ → name them onboarding_001.txt through onboarding_005.txt

Sample transcripts are already included for testing.

Account ID mapping (edit in scripts/pipeline_a.py and pipeline_b.py):

demo_001 → ACE_001
demo_002 → BSE_002
demo_003 → GCR_003
demo_004 → NHS_004
demo_005 → RRR_005

4. Run the Full Pipeline

# Run everything (Pipeline A + B)
python scripts/run_all.py

# Or run individually:
python scripts/pipeline_a.py   # Demo calls → v1 agents
python scripts/pipeline_b.py   # Onboarding → v2 agents + changelogs

5. View the Dashboard

python scripts/serve_dashboard.py
# Open http://localhost:8080/dashboard.html

n8n Setup (Optional Visual Orchestrator)

Option A: Use Python Scripts Directly (Recommended for this submission)

The Python scripts in /scripts/ are the primary automation layer. They are self-contained and run with a single command.

Option B: Import into n8n

1. Install n8n locally:

npx n8n
# OR with Docker:
docker run -it --rm --name n8n -p 5678:5678 n8nio/n8n

2. Open http://localhost:5678

3. Go to Workflows → Import → upload workflows/clara_pipeline_n8n.json

4. Set up Groq credential:

   • Go to Credentials → Add
   • Type: HTTP Header Auth
   • Name: groq-api
   • Header: Authorization, Value: Bearer YOUR_GROQ_API_KEY

5. Click Execute Workflow on "Manual Trigger" to run Pipeline A

Note: The n8n workflow uses the same Groq API calls as the Python scripts. The Python scripts are the fully functional implementation; n8n provides a visual representation of the same flow.

Retell Setup

Free Tier

1. Create account at https://www.retell.ai
2. Navigate to Agents → Create Agent
3. Each agent_spec.json output contains a system_prompt field

Manual Import Steps

1. Open outputs/accounts/{account_id}/v2/agent_spec.json
2. Copy the system_prompt value
3. In Retell UI: Create Agent → Custom LLM → Paste system prompt
4. Set voice to match voice_style field
5. Configure transfer numbers from call_transfer_protocol

Programmatic (if Retell free tier allows API access)

import requests

with open("outputs/accounts/ACE_001/v2/agent_spec.json") as f:
    spec = json.load(f)

# POST to Retell API
headers = {"Authorization": f"Bearer {RETELL_API_KEY}"}
payload = {
    "agent_name": spec["agent_name"],
    "response_engine": {
        "type": "retell-llm",
        "llm_websocket_url": "your_llm_url"
    },
    "voice_id": "11labs-Adrian"
}
requests.post("https://api.retellai.com/create-agent", json=payload, headers=headers)

Environment Variables

Variable	Required	Description
GROQ_API_KEY	✅ Yes	Free from console.groq.com
RETELL_API_KEY	❌ Optional	Only if using Retell API programmatically

LLM Usage & Zero-Cost Proof

• Model: llama-3.3-70b-versatile via Groq (free tier)
• Requests per run: ~20 total (2 LLM calls per account × 10 accounts)
• Groq free limit: 1,000 requests/day, 6,000 tokens/minute
• Cost: $0.00

---

Known Limitations

1. Groq rate limits: If running all 10 files rapidly, you may hit 6,000 tokens/minute. Add time.sleep(2) between calls if needed.
2. n8n filesystem access: The n8n workflow requires self-hosted n8n to read local files. The Python scripts are the fully functional alternative.
3. Retell API: Free tier may not include programmatic agent creation. Manual import steps are documented above.
4. JSON parsing: Occasionally LLMs return malformed JSON — the scripts include retry-safe parsing with error logging.

---

What I'd Improve With Production Access

1. Webhook trigger: Replace manual trigger with Retell/CRM webhook → pipeline fires automatically on new call
2. Retell API integration: Full programmatic agent creation and updates via Retell's REST API
3. Supabase storage: Replace local JSON files with Supabase for multi-user access and real-time updates
4. Asana integration: Real task creation via Asana API instead of local JSON mock
5. Whisper transcription: Pipe audio files through OpenAI Whisper (local) for fully automated audio-to-agent pipeline
6. Confidence scores: Add LLM self-evaluation — flag extractions with low confidence for human review
7. Diff notifications: Email/Slack notification when v2 is ready for review
