See the following sections for release notes by version. ## About Build Agent and Autonomous Engineer {#build-agent-rn__build-agent-rn-static-about} * Accelerate development by reducing backlogs and enabling faster deployment of new business applications, without requiring developers to manually handle repetitive build, test, and deployment steps. * Describe an application in natural language to autonomously generate code, organize files, and manage both UI and back-end components, making development available to users at any level. * Support automated testing through Automated Test Framework (ATF) test suite generation and execution, reducing the manual effort required to validate new or updated applications. * Decrease development costs because Build Agent handles code compilation, quality checks, and documentation of existing applications automatically. * Enable agentic development by letting you create agentic workflows, custom AI agents, and skills tailored to your organization directly from within ServiceNow Studio. {#build-agent-rn__ul_lds_nxn_dkc} See [Build Agent](https://www.servicenow.com/docs/access?context=build-agent&version=brazil&pubname=brazil-application-development&ft:locale=en-US) and [Autonomous Engineer](https://www.servicenow.com/docs/access?context=autonomous-engineer&version=brazil&pubname=brazil-application-development&ft:locale=en-US) for more information.{#build-agent-rn__build-agent-rn-highlights-2} ## Activation and other requirements {#build-agent-rn__build-agent-rn-requirements-activation} Activation information{#build-agent-rn__build-agent-rn-activation-info} : Build Agent (Trial) is a ServiceNow AI Platform feature that is active by default starting with the Brazil release.

Provide requirements as a prompt or a file upload. 2. Autonomous Engineer prompts you with questions to clarify ambiguous requirements, queries your instance to identify existing artifacts. For example, it might ask questions about tables, roles, and catalog items, and generates a plan with work items. Work items include acceptance criteria and test criteria in an Agile user story format. 3. After you approve the plan, Autonomous Engineer generates a background agent for each work item. It then builds all work items in parallel in the background, generates and runs ATF tests, and attempts to resolve test failures. 4. Items that require human intervention appear in the dashboard and in the chat panel. 5. When the plan is complete, an update set is generated for deployment to your UAT or production environment. {#build-agent-rn-2026-09__ol_xyx_1tf_fkc} Autonomous Engineer uses agent packs to give background agents product-specific domain knowledge during execution. The Custom app development agent pack is available in this release, which gives Autonomous Engineer awareness of platform tables, roles, and configuration patterns specific to custom app development.
