# react-grab

This skill lets an agent pull context for a React element you pick in a live browser: component name, file, line and HTML. Useful when a fix has to match the real DOM.

## What it does

Three delivery paths are covered. The clipboard route is manual: hover an element, hit Cmd+C or Ctrl+C, paste the result into your agent. The MCP route is tool-based — once something is selected, the agent calls `get_element_context` and gets back the file path, component, stack and HTML. A plugin and API route exists for custom actions and lifecycle hooks.

Setup starts with `npx -y grab@latest init`; for the MCP path run `npx -y grab@latest add mcp`. The browser overlay is a development-only tool and has no place in production. Node.js 22 or newer is required, so check your version before running anything — older runtimes will not work.

The skill stays inside its lane. General browser automation, session reuse with existing logins, visual UI annotation, React performance work and design-system tasks belong to other skills. Custom plugins are built on primitives such as `getElementContext(element)`, `freeze()`, `openFile(filePath, lineNumber?)` and `registerPlugin(...)`.

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/akillness/jeo-skills/tree/HEAD/.agent-skills/react-grab/SKILL.md

## When to use it
- hand an agent the real component path instead of a description
- locate the source of an element you can only see in the browser
- copy an HTML snippet into chat with one keystroke
- wire element selection to an agent through an MCP tool
- build a custom plugin on top of the API hooks

## Example prompts
- Install react-grab MCP so the agent can pull the selected button context
- Show me how to write a react-grab plugin with custom output formatting
