"content": "## AI Portfolio Assistant with RAG & CV Delivery\n\nA two-pipeline workflow that turns your Google Drive documents into a 24/7 recruiter-ready AI assistant. Recruiters chat via webhook; the agent retrieves evidence from your portfolio, answers questions, and automatically emails your CV as a PDF when requested.\n\n### How it works\n\n**Ingestion pipeline**\n1. Google Drive triggers detect new or updated portfolio documents\n2. Files are downloaded, enriched with metadata, and chunked (600 chars / 100 overlap)\n3. Chunks are embedded via OpenAI and upserted into Pinecone\n\n**Chat agent pipeline**\n1. A webhook receives `{ chatInput, sessionId, email }` POST requests\n2. Claude Sonnet 4.5 queries Pinecone (with Cohere reranking) for relevant evidence\n3. Structured output parsing extracts the answer and a `cvRequested` flag\n4. If `cvRequested` is true, the CV PDF is downloaded from Drive and emailed via Gmail\n\n**Error handling:** The Error Trigger catches any node failure and formats the error for alerting.\n\n### Setup steps\n\n1. Create a Pinecone index: dimension 1536, metric cosine, name it `portfolio-docs`\n2. Configure all 6 credentials (Google Drive, OpenAI, Pinecone, Anthropic, Cohere, Gmail)\n3. Set your Google Drive **folder ID** in both trigger nodes\n4. Set your **CV file ID** in the Download CV PDF node\n5. Personalize the AI Agent **system prompt** with your name and specialization\n6. Upload a document to Drive to trigger ingestion, then test the chat webhook"
