HEEx — 18 Operations for AI Agents

HEEx templates drive Phoenix LiveView, where server state renders straight to the DOM. act101 reads components, slots, and assigns as structure, so agents navigate LiveView UIs the way the framework thinks about them.

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze HEEx code through the act MCP server. 18 operations available: 0 refactor, 18 query, 0 analysis. Each operation is callable from Claude Code, Cursor, Codex, OpenCode, or any MCP-compatible agent host. Click any operation for a stable anchor link suitable for citation.

Query

18 query tools, the same on every supported language. Descriptions live in the shared reference: /docs/query-tools.
