What the Best Agents Share — Mardu Swanepoel, Flinn AI
Overview
This talk explores four key patterns observed in effective AI agents, drawing inspiration from existing tools like Cursor, Claude, and Harvey. The core thesis is that by studying and adapting these successful patterns, developers can build more capable and user-friendly agents. The presentation emphasizes learning from successful designs to improve agent development.
Who should watch
- AI Engineers
- Product Managers
- Builders of AI agents
- Those seeking to improve agent output quality and user experience
- Developers interested in agent design patterns
Key takeaways
- **Focus Modes:** Constraining an agent's action and input space into specific modes (e.g., planning, research) improves output quality for engineers and manages user expectations. Cursor exemplifies this by allowing users to switch between distinct operational modes.
- **Transparent Execution:** Making an agent's thought process, actions, and tool usage clear to the user shifts the dynamic from delegation to collaboration, fostering trust and enabling early intervention. Claude's co-work feature and Manifold's task progress indicators demonstrate this.
- **Personalization:** Equipping agents with user-specific knowledge, principles, and patterns increases their speed of understanding and ensures they perform the *right* task, not just *a* task. Harvey's playbooks and Claude's skills/connectors facilitate this.
- **Reversibility:** Allowing users to undo agent actions mitigates the cost of mistakes, encouraging bolder experimentation and tackling higher-value tasks. Cursor offers granular rollback options, and Harvey integrates with native document editing APIs for undo functionality.
- *The core idea is to steal like an artist, not to take something that is not your own, but to go and study something deeply and make it your own.*
- *Focus modes constrain the action and input space, improving agent output quality and aligning user expectations.*
Notable quotes
Mardu Swanepoel suggests that the best agents share common patterns, and understanding these can lead to better agent development.
Swanepoel describes focus modes as a way to constrain the agent's action and input space, leading to improved output quality and better user expectation management.
Transparent execution aims to shift from delegation to collaboration, building trust by making the agent's process clear.
