Record Replay - Content Renderer Agent

This directory (components/record_replay/content/renderer) contains the content-process agent code for the Record Replay feature in Chromium.

While the core browser component handles the central coordination and state management, this directory provides the implementation to perform actions within the renderer's DOM. It observes user interactions (clicks, text input, selections) on the web page and reports them via Mojo to the browser process. It also executes commands sent from the browser process to replay actions within the DOM.

This subcomponent is specific to the content/ layer and interacts with Blink directly.

Key Components

• RecordReplayAgent: The primary class that inherits from content::RenderFrameObserver and blink::WebRecordReplayClient. It acts as the bridge between the DOM events and the Mojo communication with the browser process.
• Mojo Implementation: Implements the mojom::RecordReplayAgent interface, providing commands like DoClick, DoSelect, DoPaste, and GetElementSelector.
• Test Support: Includes record_replay_agent_test_api.h and record_replay_agent_browsertest.cc for robust verification of renderer-side logic using the content::RenderViewTest harness.

Upkeep / Guidelines for AI Agents

NOTE: For detailed information about each component, please refer to the documentation in the respective header files (*.h) within this directory.

[!IMPORTANT] This document functions as a living document. AI agents introducing any major sub-features, changing process or Mojo interfaces, or solving significant ambiguities MUST update this file to reflect the updated mental model of the feature tree.
