English | 简体中文 Tactus The First Browser AI Agent Extension with Agent Skills Support [![Chrome Version][chrome-version-shield]][chrome-store-link] [![Chrome Users][chrome-users-shield]][chrome-store-link] [![Firefox Version][firefox-version-shield]][firefox-store-link] [![Firefox Users][firefox-users-shield]][firefox-store-link] Tactus is an innovative browser extension that brings the Agent Skills specification to the browser environment, enabling AI Agent to perform complex tasks through an extensible skill system. Triggering skills can achieve prompt injection for specific scenarios, and common workflows can be encapsulated in scripts for execution, replacing repetitive automated operations of AI Agents. This approach is both fast and token-efficient.
