   Postman details Agent Mode architecture on Amazon Bedrock

   In an Amazon Machine Learning Blog post, Postman and AWS describe the production architecture behind Agent Mode, Postman's AI-native way to work across API testing, documentation, discovery and implementation. The post says the team expected model quality and prompt design to be the hardest problems, but deeper challenges came from integrating an agent into an 11-year-old product built around interface-driven assumptions. The described patterns include dynamically scoping tools per task, favoring schema-based reads over tool proliferation, building purpose-made context handlers per entity, and treating the context window as a scarce budget. Inference runs on Amazon Bedrock with cross-Region inference, multi-tier prompt caching and model-dependent data-retention settings. Agent Mode requires user approval before actions that change application state and uses Amazon Bedrock Guardrails to redact personally identifiable information. Postman says its production implementation is proprietary and not available as a public sample repository.
