Three high-impact use cases

The skill doesn't just answer one-off questions — it keeps your agent on track across full WhatsApp workflows. Same install, same knowledge base, from first message to production bot.

Your agent sets up webhooks, filters from_me, picks the right send tool per message type, and follows the full bot recipe — without inventing endpoints

Create groups, post to channels via @newsletter IDs, manage admins — with the correct ID formats and community announcement rules baked in

Rate-limited broadcast loops, number validation before sends, and warm-up-aware pacing — patterns copied from production integrations, not guessed

What Is a WhatsApp Agent Skill — and Why It Matters

An Agent Skill is a structured knowledge file (SKILL.md + references) that loads into AI coding agents through the open Agent Skills standard. Instead of pasting API docs into every conversation, the skill teaches your agent Whapi.Cloud rules before it writes code.
WhatsApp integrations fail in predictable ways: wrong Chat ID suffixes (using @s.whatsapp.net for groups), polling instead of webhooks, hallucinated field names, posting to community sub-groups instead of the Announcements group. The Whapi Agent Skill encodes fixes for all of these — with correct/incorrect examples and explicit anti-hallucination checklists.
Pair it with whapi-mcp for the full stack: MCP gives your agent the tools; the Agent Skill teaches it which tool to use, with which parameters, in which situation. Together they prevent the three most common errors: wrong Chat IDs, wrong auth headers, and polling instead of webhooks.
One-command install: npx skills add Whapi-Cloud/whapi-whatsapp-api-skill
Fewer broken integrations: Correct patterns from the first prompt, not after hours of debugging.
Progressive loading: Skill metadata at startup, full references only when needed — minimal token overhead.

Frequently asked pricing questions

WhatsApp Agent Skill is a structured knowledge package that teaches AI coding agents (Cursor, Claude Code, Copilot, etc.) the correct patterns for building WhatsApp automations with Whapi.Cloud. It covers Chat ID formats, webhook setup, message types, groups, channels, and communities — preventing common integration errors like wrong ID suffixes or polling anti-patterns.
Install with one command: `npx skills add Whapi-Cloud/whapi-whatsapp-api-skill`. The skill auto-detects your AI agents (Cursor, Claude Code, etc.) and configures itself. Add `--agent cursor` or `--agent claude-code` to target specific agents only. Requires Node.js 18+.
WhatsApp Agent Skill works with 40+ AI agents including Cursor, Claude Code, GitHub Copilot, Codex, and any agent supporting the Vercel Labs Agent Skills standard. The skill auto-loads when your agent detects WhatsApp-related tasks.
WhatsApp Agent Skill is knowledge (the recipe); whapi-mcp is tools (the pantry). The Skill teaches your AI agent which MCP tool to use, with which parameters, and in which situation. Use both together: MCP provides 165 WhatsApp API tools, the Skill provides the patterns to use them correctly.
No, WhatsApp Agent Skill is designed specifically for Whapi.Cloud's WhatsApp API. It teaches patterns for Whapi's extended feature set — including groups, channels, communities, and statuses — which the official Meta API does not support.
The Skill encodes seven reference categories with correct vs. incorrect examples: (1) Core concepts — Chat ID formats (@s.whatsapp.net, @g.us, @newsletter), (2) Sending messages — tool selection per content type, (3) Receiving messages — webhook structure and why polling is wrong, (4) Groups — management patterns, (5) Channels — @newsletter IDs and posting rules, (6) Communities — announcement group vs sub-groups, (7) Integration patterns — bot recipes and broadcast loops.
Yes, the WhatsApp Agent Skill itself is free to install and use. You only pay for Whapi.Cloud API access if you need production volumes — the Sandbox plan is free forever (5 conversations/month, 150 messages/day), and Developer Premium is paid for unlimited messaging.
