Full Tutorial: The Most Underrated AI Agent for Coding and Product Work | Eno Reyes (Factory)
Plus a 700-word AI skill that makes AI agents much better at reviewing PRDs, prioritizing features, and thinking like a senior PM on your team
Dear subscribers,
Today, I want to share a new episode with Eno Reyes.
Eno is the co-founder of Factory and the most AI-native founder I know. He gave me a live demo of how he builds apps with AI agents, but what really blew my mind was his AI skill that writes PRDs, prioritizes features, and makes AI think like a senior PM on your team. Watch the interview to see him walk through it and I’ve also pasted the full skill below for paid subscribers to copy.
Watch now on YouTube, Apple, and Spotify.
Eno and I talked about:
(00:00) What makes Droid different from other AI agents
(03:46) Live demo: Building a speed reading app from meeting notes
(08:11) The difference between spec mode and plan mode
(12:04) How real engineers use AI agents vs vibe coders
(16:33) Skills vs MCPs vs hooks: When to use each one
(19:02) Eno's PM skill that completely blew my mind
(22:46) Why Factory hires product engineers vs. PMs
(27:09) How a 40-person team competes with Cursor and Anthropic
I’m proud to partner with…Linear
As coding agents take on more engineering work, a lot happens invisibly. Someone can go from a bug report in Slack to a shipped fix without creating any record of what happened. That’s fine for speed, but coordination gets harder as you scale.
Linear integrates directly with tools like Cursor and Codex so anyone can see what an agent is working on and who assigned the task. Product teams at OpenAI, Ramp, and Block all use Linear to collaborate with AI agents.
Top 10 takeaways I learned from this episode
Eno’s PM skill agent is genuinely the most impressive I’ve seen. It covers:
Product principles and positioning. The agent reads Factory’s core beliefs about how they build product and how they position themselves in the market.
The 11-star experience. The skill links to Factory’s description of its most compelling 11-star user experience borrowed from Airbnb’s Brian Chesky.
PRD template and review rubric. The skill not only edits PRDs using Factory’s template but also scores each PRD and flags critical gaps.
Prioritization framework. The skill can prioritize and trade-off features.
Language guidance. The skill includes guidance on clear and concise copy.
Here’s the full 700 word PM skill for you to copy and paste into your favorite AI project or coding app. Just save it as a md file and replcae the links with your own:
