Overview
- The guidance, posted on Amazon's internal news site, makes Kiro the recommended AI-native development tool for employees.
- The memo was signed by AWS senior vice president Peter DeSantis and e-commerce foundation senior vice president Dave Treadwell.
- Amazon said it will continue supporting third-party tools already in use but discouraged adding new ones, a move that could limit Codex, Claude Code, and Cursor inside the company.
- The push follows Kiro's recent global expansion and seeks employee feedback to accelerate improvements to the in-house service.
- The policy comes despite Amazon's about $8 billion investment in Anthropic and a seven-year $38 billion cloud deal with OpenAI; Amazon confirmed the memo, while the named vendors did not immediately comment.
