twilio-enterprise-knowledge

✓★ 4,081

by openai

Add knowledge retrieval to AI agents using Twilio's Enterprise Knowledge product. Enterprise Knowledge is a centralized, searchable repository of your organization's documents, websites, and content — FAQs, support policies, warranty terms, product catalogs. Current models don't have access to how you run your business today. Enterprise Knowledge gives agents a way to query this repository during a conversation and ground their responses in your actual approved source material. This skill covers provisioning a Knowledge Base and uploading knowledge sources from web URLs, PDFs, and raw text, and running semantic search to retrieve relevant chunks at runtime. Enterprise Knowledge is shared across your organization — it captures what your organization knows and how it is meant to run. It is distinct from Conversation Memory (twilio-customer-memory), which is scoped to individual end-customers and captures what you know about a specific person. The two are designed to be combined: enterprise content for business practices, customer memory for personalization.
