Third-party tools for Chrome DevTools for Agents

Standard developer tools for coding agents, like those in Chrome DevTools, offer basic functions but lack interaction with an application's specific internal state. DevTools for agents introduces custom, third-party developer tools, enabling agents to interact with any aspect of an app through plain JavaScript. This allows agents to inspect and modify state, bypass authentication, or interact with internal components like routers. For instance, agents can now efficiently diagnose runtime issues like cache misses by querying custom metrics services exposed via DevTools, avoiding the noise of excessive console logs. Similarly, verifying role-based access is streamlined with custom "impersonate" tools that let agents seamlessly switch user profiles without manual logins. Framework and library authors can also leverage this functionality. The Angular team, for example, has implemented built-in tools for debugging dependency injection and signal graphs. This feature can be extended to animation libraries for controlling playback or content management systems for seeding demo content, significantly enhancing debugging efficiency for coding agents. To get started, consult the documentation and enable the experimental flag if necessary.
