Coding Agent Skills

Coding Agent Skills provide intelligent, contextual knowledge about the Zavu API directly inside your favorite AI coding agent. Instead of searching docs or copying code snippets, your agent automatically understands channels, message types, webhook patterns, and API conventions — and writes correct code on the first try.

Supported Agents

Skills work with 40+ AI coding agents. The following are always included:

Plus 30+ additional agents including Antigravity, Augment, CodeBuddy, Command Code, Continue, Cortex Code, and more. During installation you can select which agents to install to.

Install

terminalCopy
npx skills add zavudev/zavu-skills

The installer will prompt you to select which agents you want to install the skills to. Your agent will automatically load relevant skills based on what you're building.

Available Skills

Twelve skills ship in the repo. The agent-building ones come first, because they are the ones that write code.

How It Works

Skills are markdown files that your coding agent loads automatically based on your task. When you ask it to "send a WhatsApp message" or "set up webhooks", it already knows:

• Which channel to use based on message type and recipient
• The correct TypeScript SDK patterns, and the REST call for any other language
• Business rules like the WhatsApp 24h window and what a new account can send
• Error codes and how to handle them
• API constraints (button limits, pagination patterns, etc.)

Example: Channel Selection

When you ask your agent to send a message, the send-message skill gives it this decision tree:

CodeCopy
Is recipient an email address?
  → channel = "email"
Is message type non-text (image, video, buttons, etc.)?
  → channel = "whatsapp" (auto-selected)
Need voice call / TTS?
  → channel = "voice"
Want Zavu to pick the channel?
  → channel = "auto" (first channel the sender has configured
    that the recipient's address can receive)
Default?
  → channel = "sms"

Your agent uses this logic to pick the right channel without you specifying it.

Skills + CLI

For the best experience, install the skills and sign the CLI in:

terminalCopy
# Skills: context and intelligence (works with 40+ agents)
npx skills add zavudev/zavu-skills

# CLI: acts on the API. Opens the browser once; in CI, set ZAVUDEV_API_KEY instead
npx zavudev login

With both, your coding agent can:

1. Decide the right approach using skills (channel selection, template vs. free-form, etc.)
2. Act on your account with the CLI: create senders, send messages, deploy functions
3. Write production-ready code using correct SDK patterns

The MCP server is being rebuilt and does not work in its default configuration today.

What You Can Build

Once skills are installed, try asking your agent:

Skill Details

Always-Loaded: Zavu Rules

The zavu-rules skill loads automatically in every conversation. It provides:

• SDK init pattern for TypeScript, and what to use from other languages
• Authentication conventions (ZAVUDEV_API_KEY, key prefixes zv_live_/zv_test_)
• E.164 phone format and channel enum values
• Cursor-based pagination pattern
• Error handling with APIError
• Key business rules (WhatsApp 24h window, sending limits for new accounts, URL verification)

On-Demand Skills

Other skills load when your agent detects they're relevant to your task:

Requirements

• Any supported AI coding agent (Cursor, Claude Code, Copilot, Cline, etc.)
• Node.js 18+ (for npx skills add)
• Optionally: ZAVUDEV_API_KEY environment variable, for the CLI in a non-interactive environment
