Episode notes
From Autocomplete To Thinking Agents
- Agentic tools evolved from autocomplete to multi-turn agents that can reason about your codebase.
- This shift enabled generating large portions of code up front and editing via agents instead of typing every function.
Senior Engineers Lead Agent Adoption
- Senior engineers adopted agents faster and used written instructions for complex problems.
- This pattern motivated AWS to invest in spec-driven development to handle complexity and collaboration.
Prefer Specs For Complex Work
- Use high-level specs for complex problems and keep vibe coding for simple tasks.
- Make specs shareable so teams and agents can collaborate and reuse project context.
