AI Agent Skill for Chat Integration | CometChat
CometChat
A CometChat skill that lets AI coding agents integrate chat, messaging and calls into projects in minutes with automatic setup.
Key features
- One-File Skill Integration: A single skill file handles framework detection, SSR protection, credential and env var setup automatically so an AI agent can integrate CometChat rapidly and safely.
- Multi-Agent Compatibility: Built to work with Claude Code, Cursor, Codex, VS Code Copilot, Kiro, Windsurf, Cline and 30–50+ other AI coding agents so the same skill can be reused across agent ecosystems.
- Framework-Specific Code Generation: Produces production-grade integration code tailored to the project's existing files across React, Next.js, React Native, Angular, Android, iOS, and Flutter.
- CLI Orchestration: Uses @cometchat/skills-cli under the hood (can be invoked directly) to run install, detect, and scaffold commands programmatically from the agent.
- Component Library & Theming: Ships with a large component catalog (60+ components), theming presets (Slack, WhatsApp, iMessage, Discord, Notion), and placement patterns (route, modal, drawer, widget) to speed UI integration.
- Iteration & Feature Menu: After initial integration the /cometchat command or agent menu lets you iteratively add features (reactions, dark mode, production auth, polls, AI features, file sharing) and run troubleshooting tasks.
- Mobile & Native Support: Adds end-to-end mobile features like push notification setup (APNs, FCM), testing setups (Jest, RNTL, Detox/Maestro) and platform-specific fixes for React Native, Android and iOS.
- SSR Safety & Credential Handling: Automatically implements server-side rendering safety checks and secure handling of API keys and credentials to avoid accidental exposure in generated code.
- AI-driven integration flow: agent asks project-specific questions and generates tailored integration code
- Framework detection and multiproject support: React, Next.js, React Native, Angular, Android, iOS, Flutter, Vite, and web/native variants
- SSR protection and framework-specific patterns (Next.js/SSR-safe wiring)
- Automatic credential setup and signup flow from terminal (no CometChat account required up front)
- Underlying CLI (@cometchat/skills-cli) used to run integration commands programmatically or manually
- Component catalog (60+ components) and feature modules (40+ features) including calls, polls, AI features, reactions, file sharing
- Voice & video calls support via Calls SDK (WebRTC-backed), group calls, screen sharing, PiP, recording hooks
- Push notifications setup for React Native (APNs + FCM) and other notification integrations
- Testing scaffolding for React Native (Jest, RNTL, Detox/Maestro) and troubleshooting helpers
- Theming presets and customization (Slack/WhatsApp/iMessage/Discord/Notion presets, brand colors)
- Docs MCP integration to give the agent live access to CometChat documentation for advanced customization
- MIT-licensed skill repository with re-runnable /cometchat command to iterate features after initial integration
Best for
- Rapidly add chat, messaging, and voice/video calling to an existing React or Next.js web app by asking an AI agent to run /cometchat and scaffold provider, routes, and env vars tailored to the codebase.
- Integrate real-time chat into a mobile app (React Native, Android, iOS, Flutter) including push notifications and testing harnesses, with the agent installing SDKs and wiring platform-specific configuration.
- Use AI coding agents to iteratively enhance a product’s communication features—add reactions, polls, file sharing, or switch themes/layouts by re-running the skill’s iteration menu rather than manual coding.
- Onboard developers quickly with a Replit template that includes preinstalled CometChat skills so a student or prototype can get a working chat integration without creating a CometChat account first.
- Customize chat UI and behavior for multi-tenant SaaS or branded apps by leveraging the component catalog, theming presets, and placement patterns the agent can configure and modify automatically.
- Add real-time chat and messaging to a new or existing web or mobile app via an AI coding agent
- Enable voice and video calling (including group calls, screen share, recording hooks) in telehealth, education, or collaboration apps
- Rapidly scaffold chat UI, providers, routes, and environment variables for React, Next.js, React Native, Angular, Flutter, Android, or iOS projects
- Configure push notifications, testing suites, and platform-specific permissions as part of CI/dev setup
- Iteratively extend chat functionality (reactions, polls, file sharing, AI features) by re-running the skill or issuing bot commands
