When you run an implementation plan involving a ServiceNow product, Autonomous Engineer loads the relevant agent pack to enable accurate, product-specific artifact generation during plan execution. These packs also incorporate Automated Test Framework (ATF) Test Agent capabilities to validate completed work items against acceptance criteria. Show full answer Show less To use Autonomous Engineer and its agent packs, you must first install the Autonomous Engineer app from the ServiceNow Store and verify your entitlements. ## How Agent Packs Work * All agent packs share a common base that provides core capabilities for background agents during execution. * Product-specific packs extend this base with knowledge tailored to their respective ServiceNow products. * When a plan involves a product, the corresponding agent pack is loaded and used by all background agents working on related work items. * Agent packs include Test Agent functionality to automatically generate and run tests validating work items. ## Agent Packs in the Brazil EA (Patch 0) Release * **Planning pack:** Parses requirements, conducts interviews for clarity, applies ServiceNow best practices, and generates structured work item plans. * **Platform development pack:** Provides domain knowledge specific to custom application development on the ServiceNow platform, including awareness of platform tables, roles, and configuration patterns to ensure artifacts align with platform standards. ## Use with Custom Applications Agent packs are product-specific and provide domain knowledge for standard ServiceNow product implementations. For custom application development, Autonomous Engineer leverages the Platform development pack to handle platform-specific conventions. If your implementation includes both a ServiceNow product and custom applications, Autonomous Engineer applies the relevant agent packs accordingly. Work items targeting custom artifacts are managed by the base capabilities without product-specific domain knowledge. Agent packs bundle the domain knowledge, tools, and skills that Autonomous Engineer uses to implement ServiceNow products. When you use Autonomous Engineer to implement a ServiceNow product, Autonomous Engineer loads an agent pack to understand that product. An agent pack bundles the domain knowledge, tools, and skills that background agents require to generate accurate, product-specific artifacts during plan execution. Agent packs are active during Autonomous Engineer execution. Note: You must install the Autonomous Engineer app from the ServiceNow Store. Check your entitlements to see whether you can use Autonomous Engineer. ## How agent packs work {#ae-agent-packs__ae-agent-packs-how-they-work} All agent packs share a common base that provides the core capabilities available to every background agent during Autonomous Engineer execution. Product-specific packs extend this base with product-specific knowledge. When you run a plan that involves a ServiceNow product, Autonomous Engineer loads the corresponding agent pack. That agent pack is available to every background agent working on a work item for that product. Each agent pack also includes Automated Test Framework (ATF) Test Agent capabilities for the product it covers. When a background agent completes a work item, it uses Test Agent in the agent pack to generate tests. The tests validate the work item against the acceptance criteria in your plan. For details on Test Agent use in Autonomous Engineer, see [Test what you built with Build Agent](https://www.servicenow.com/docs/GtUNVhSWEkRrYJTHFi1dvQ "Test Agent generates test coverage for code created by Build Agent, executes tests, and performs root cause analysis (RCA) on failures. Prompt Test Agent to complete build-to-test workflows in a single development session without manual test authoring or failure investigation."). For details on using agent packs to implement ServiceNow products and applications, see [Use Autonomous Engineer to implement an application](https://www.servicenow.com/docs/wWxXgCHDcF3fVt_YmaSgCg "Use Autonomous Engineer (powered by Build Agent) to generate a plan from your requirements and build all work items in parallel, without creating each artifact individually. When implementing a ServiceNow product or application, Autonomous Engineer uses agent packs to give background agents product-specific domain knowledge."). ## Agent packs and custom applications {#ae-agent-packs__ae-agent-packs-custom-apps} Agent packs are available in the Brazil EA (Patch 0) release: * The Planning pack, which parses requirements and interviews you for clarity, applies ServiceNow best practices, and generates a structured plan of work items. * The Platform development pack, which provides domain knowledge for implementing custom applications on your instance. The Platform development pack gives Autonomous Engineer awareness of platform tables, roles, and configuration patterns specific to custom app development. The awareness helps generated work items and artifacts align with standard platform conventions. Agent packs are specific to ServiceNow products. Autonomous Engineer applies instance awareness and your requirements to generate the plan without product-specific domain knowledge. If your implementation spans a ServiceNow product and custom application development, Autonomous Engineer will apply the appropriate agent packs. The agent pack applies only to work items that target the product. Work items for custom artifacts are handled by the base implementation capabilities.
