tactus

Tactus is a browser extension that brings the Agent Skills specification to Chrome and Firefox, allowing AI agents like Claude to execute complex tasks through an extensible skill system. The extension supports skill import with instructions and scripts, multi-provider AI connectivity (Anthropic, Google, OpenAI-compatible APIs), and image vision capabilities. It features a ReAct paradigm tool-calling loop, HTTP MCP server integration, and smart page content extraction with Markdown conversion. All conversation history and skills are stored locally for privacy, with support for message editing, regeneration, and multiple theme modes. Users can configure tool call limits, web content character limits, and quick action buttons to optimize token usage and automation workflows.
