Amazon Q Developer CLI Cheatsheet - AWS Official AI Coding Agent Full Reference

Amazon Q Developer CLI is AWS official terminal AI coding agent, aimed at developers who live in the AWS ecosystem and want the model to understand and edit a local repo while connecting to AWS services/docs. It stands out by deep AWS integration (explaining and acting on AWS resources) and supports both q one-line queries and agent mode. This sheet covers install/login, chat/one-line queries, and agent execution.

Tips

  • Amazon Q Developer CLI is AWS-official; when discussing AWS resources (Lambda/IAM/CloudFormation/EC2) it fits cloud context better than general coding agents — great for cloud-native teams.
  • One-line `q "..."` uses print mode and pipes straight into scripts/CI; for complex multi-step work, enter `q chat` then `/q` to switch to agent mode.
  • Prereq: `q login` with AWS Builder ID or IAM Identity Center; manage profile/region via `q config`.
  • /doc and /test are hidden efficiency wins — run them against code to fill in docs and unit tests without writing by hand.
