Each pack contains domain knowledge, tools, and skills tailored to specific ServiceNow products, enabling background agents to generate accurate, product-specific artifacts during plan execution. Autonomous Engineer loads the relevant agent pack when implementing a ServiceNow product, ensuring that work items are handled with specialized expertise. Agent packs also incorporate Automated Test Framework (ATF) Test Agent capabilities to automatically generate tests that validate work items against acceptance criteria. Show full answer Show less To utilize Autonomous Engineer and its agent packs, you must install the Autonomous Engineer app from the ServiceNow Store and verify your entitlements. ## How agent packs work * All agent packs share a common foundational base that provides core capabilities for background agents during Autonomous Engineer execution. * Product-specific agent packs extend this base with specialized knowledge to support the implementation of particular ServiceNow products. * When a plan involves a specific product, Autonomous Engineer loads the corresponding agent pack, making it available to every background agent working on related work items. * Agent packs include ATF Test Agent features to generate tests that validate completed work items against your plan's acceptance criteria. ## Agent packs and custom applications * The Australia Patch 6 release includes key agent packs: * **Planning pack:** Parses requirements, conducts interviews to clarify details, applies implementation guidelines, and generates a structured plan of work items. * **Platform development pack:** Provides domain knowledge specific to developing custom applications on your ServiceNow instance, including platform tables, roles, and configuration patterns. * During planning, Autonomous Engineer uses structured questions with default values and alternatives to gather clear requirements. Follow-up questions are asked if deviations are detected. * Agent packs are product-specific. For implementations spanning both ServiceNow products and custom application development, Autonomous Engineer applies the relevant agent packs accordingly: * Product-specific packs handle work items related to that product. * The base implementation capabilities handle work items related to custom artifacts without specific product knowledge. ## Practical benefits for ServiceNow customers * Agent packs ensure that Autonomous Engineer leverages comprehensive, product-specific expertise to generate precise implementation plans and artifacts. * Integration with ATF Test Agent enables automated validation of work items, improving quality assurance and compliance with acceptance criteria. * Support for both standard ServiceNow products and custom application development provides flexibility for varied implementation needs. * Structured requirement gathering improves clarity and accuracy in planning, reducing ambiguity in project execution. 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/b1zgznG7JglS4yqPK_m6zg "Test Agent generates test coverage for code created by Build Agent or Autonomous Engineer, 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/d2GB_9rUuacq5YbGVC6RjA "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 Australia Patch 6 release: * The Planning pack, which parses requirements, interviews you to resolve unclear details, applies implementation guidelines for ServiceNow products, 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. During planning, Autonomous Engineer asks structured questions to gather requirements. Each question can include a default value and alternative answers. When your answers meet a deviation condition, the pack asks follow-up questions before it generates the plan. 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.
