Agent Skills
AI coding assistants such as Claude Code or Codex can generate DHTMLX Gantt code, but they often make mistakes with specialized APIs: wrong prop names, missing CSS imports, incorrect callback signatures, or mixing incompatible data patterns. Agent skills address this by teaching the assistant the correct patterns and known pitfalls before it writes code.
Unlike the MCP server, which provides real-time API reference, skills focus on integration patterns, decision points, and failure prevention.

Available Skills
DHTMLX JS Gantt
Covers integration of the core JavaScript Gantt into plain JavaScript and TypeScript applications. The skill recognises all delivery channels - the free dhtmlx-gantt (Standard / GPL) package, the @dhx/trial-gantt evaluation package, the commercial @dhx/gantt package, and <script> / CDN loading - and adapts setup, data, and theming guidance to each.
Review the rules in the GitHub repository.
DHTMLX React Gantt
Covers integration of @dhtmlx/trial-react-gantt and @dhx/react-gantt into React applications. The skill teaches the assistant the wrapper-specific setup, data ownership and persistence patterns, and theming approach that are easy to get wrong - and lists known pitfalls extracted from real projects with concrete fixes.
Review the rules in the GitHub repository.
For a worked example of these patterns applied end-to-end, see the React Gantt Lovable Starter - a multi-project planner generated in Lovable, with the full build recipe in its lovable/ folder.
DHTMLX Angular Gantt
Covers integration of @dhtmlx/trial-angular-gantt and @dhx/angular-gantt into Angular applications. The skill teaches the assistant the wrapper-specific setup, data ownership and persistence patterns (data.save / data.batchSave), and theming approach that are easy to get wrong - and lists the known failure modes with concrete fixes.

Installing
npx skills add DHTMLX/skills --skill dhtmlx-js-gantt
npx skills add DHTMLX/skills --skill dhtmlx-react-gantt
npx skills add DHTMLX/skills --skill dhtmlx-angular-gantt
Manual Installation
Clone or download the DHTMLX/skills repository and copy the relevant skill folder (dhtmlx-js-gantt, dhtmlx-react-gantt, or dhtmlx-angular-gantt) into your project's skills directory (e.g., .claude/skills/ for Claude Code, .cursor/skills/ for Cursor).
Using Skills with MCP
Skills and the MCP server are complementary. MCP gives your assistant access to real-time API documentation - method signatures, property values, configuration options. Skills teach it the integration patterns that prevent common mistakes. For best results, use both. See DHTMLX MCP Server for setup instructions.
