Sharing a few of my favorite prompt snippets for coding: For iterating on a spec: Please step back and think again. How can we make this SIMPLER and DUMBER while still achieving our goals? For planning: Please research the codebase to make sure you fully understand how stuff currently works, and make a detailed plan to achieve the above. Your plan must be fully fleshed out and include only concrete actions such as editing files and running commands (ie. your plan cannot include actions like “read this file”). Your plan must also include how you will verify it is correct yourself, end-to-end. Don’t make any code changes yet. Research now as much as you need and then chat back with your full plan when ready. For debugging: Please think carefully and truth seek. Don't just blindly re-run things and hope they will work. Read the code, and liberally add temporary logging statements anywhere in the codebase to verify logic works as you expect (just remember to not commit them). Dig deep and take the time to really figure out the root causes of problems.

Our cofounder @SimonLast hasn't written a line of code since last summer. With custom agents running while he sleeps, entire products get built without him touching the keyboard. Custom agents run his inbox. Route bugs. File tasks. Search across Slack, Drive, and Notion—and find him answers, not links. He sat down with @Saranormous on @NoPriorsPod to share what it looks like when the entire company runs on agents.

MCP sucks honestly It eats too much context window and you have to toggle it on and off and the auth sucks I got sick of Claude in Chrome via MCP and vibe coded a CLI wrapper for Playwright tonight in 30 minutes only for my team to tell me Vercel already did it lmao But it worked 100x better and was like 100LOC as a CLI
Morgan@morganlinton

The cofounder and CTO of Perplexity, @denisyarats just said internally at Perplexity they’re moving away from MCPs and instead using APIs and CLIs 👀

Our cofounder @simonlast built the first Custom Agent at Notion. It had one job: route product feedback. Then he gave it a blank page and let it figure out the rest. Now the whole company relies on it 👀

Custom agents are here – I'm so proud of the team for this launch! My personal favorite: I set up an email triage custom agent a few months ago and it completely solved email for me. I get a daily recap of what I need to see, and anything I don't is automatically archived.

@simonlast Since you think about this a lot more than anyone: does capitalizing words for emphasis actually work? Or placebo?

It’s so silly that this works, but alas: after plan mode, ask “what are the edge cases you didn’t consider?”

@melvynx I don't understand how this is breaking news. I have a Claude memory protocol that uses Notion as a database so I can collaborate with Claude's memory directly. So many other Claude memory libraries out there too.
