Episode notes
Probability Can't Fix Probability
- Relying on one LLM to check another creates circular validation and fails when models share biases.
- Treat agents as software with rules and interception, notacles of vague 'vibe' checks.
Intercept Agent Failures Programmatically
- Use software patterns to intercept and patch LLM failures like hallucinations and PII leaks.
- Deploy tools like the open source Steer SDK to inject fixes without changing core code.
Bun Team Joins Anthropic
- Anthropic acquired the Bun team despite Bun being open source, highlighting the value of engineering talent.
- Jerod suggests Anthropic wanted the Bun team's expertise more than the code itself.
