Agent Builder is a design-time AI assistant in Optimizely Opal that helps you create reliable agents and skills. Use Agent Builder to catch reliability issues at the source, before an agent runs in production.
Agent Builder analyzes your in-progress work and provides guidance as you build. The assistant provides the following types of guidance:
- Identifies ambiguous instructions in agent prompts and skills.
- Validates the format of your configuration.
- Suggests missing tools.
- Generates evaluation samples for testing.
- Flags potential failure modes before you deploy.
Agent Builder is part of the Agent Reliability Engagement (ARE) framework. The assistant refines its guidance over time as Opal collects data from execution guardrails, autonomous corrections, and evaluation scores.
When to use Agent Builder
Use Agent Builder when you author or update an agent. The assistant works best at design time (before an agent runs) to prevent the most common reliability issues including the following:
- Vague or incomplete skills.
- Missing tool dependencies.
- Skipped evaluation samples.
