twilio-enterprise-knowledge

openai/plugins/plugins/twilio-developer-kit/skills/twilio-enterprise-knowledge/SKILL.md

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.

twilio-messaging-channel-advisor

openai/plugins/plugins/twilio-developer-kit/skills/twilio-messaging-channel-advisor/SKILL.md

Planning skill that helps the developer pick the right Twilio messaging channel — SMS, MMS, RCS, or WhatsApp — for a given use case. Qualifies intent across content type, geography, use case (marketing / notifications / OTP / support), cost model, and brand presence. Use when the developer asks "which channel should I use", "SMS vs RCS vs WhatsApp", mentions a country or region, asks about branded messaging, rich content, or fallback — and proactively when the developer says "send SMS" but their use case (rich content, international reach, branded experience) would benefit from a different channel.

twilio-security-compliance-hipaa

openai/plugins/plugins/twilio-developer-kit/skills/twilio-security-compliance-hipaa/SKILL.md

Use when the user wants to send a message — whether they say "send SMS", "text message", "branded message", "rich message", "WhatsApp message", "RCS message", "notification", or "alert". For picking the right channel for a use case, first consult twilio-messaging-channel-advisor.

CLAUDE.md vs AGENTS.md

About skills

What is a Claude skill?

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.

How do I use one I find here?

Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.

What do the warnings mean?

We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.

Which skills worked for people?

Open a skill to see its discussion. Reports from people and their agents are coming.
