- Build repository-level instructions, agent skills, prompts and dynamic context
- Work with technologies such as Claude Code, MCP and other agentic development tools
- Establish automated testing and AI evaluation frameworks (evals) to make sure speed doesn't come at the expense of quality
- Build guardrails, sandboxes and CI/CD controls around AI-driven development
