Past year I have leaned on AI so much I genuinely can't remember the last time I wrote meaningful code on my own. No idea if that's made me better or worse at my job.

Maybe judgment and knowing what to ask matter more than writing code now.

CLIs are super exciting precisely because they are a "legacy" technology, which means AI agents can natively and easily use them, combine them, interact with them via the entire terminal toolkit.

E.g ask your Claude/Codex agent to install this new Polymarket CLI and ask for any arbitrary dashboards or interfaces or logic. The agents will build it for you. Install the Github CLI too and you can ask them to navigate the repo, see issues, PRs, discussions, even the code itself.

Example: Claude built this terminal dashboard in ~3 minutes, of the highest volume polymarkets and the 24hr change. Or you can make it a web app or whatever you want. Even more powerful when you use it as a module of bigger pipelines.

If you have any kind of product or service think: can agents access and use them?

- are your legacy docs (for humans) at least exportable in markdown?
- have you written Skills for your product?
- can your product/service be usable via CLI? Or MCP?
- ...

It's 2026. Build. For. Agents.

Taking a hard look at our testing reality:

- Automated coverage & CI/CD discipline
- Performance, security & accessibility gaps
- Defect leakage trends
- Production monitoring & feedback loops

Goal: surface the real gaps -> fix what actually hurts quality the most

Database Types You Should Know in 2025

There’s no such thing as a one-size-fits-all database anymore. Modern applications rely on multiple database types, from real-time analytics to vector search for AI. Knowing which type to use can make or break your system’s performance.

Migrated 600 tests from Selenium WebDriver to Playwright:
Selenium ~2h 30m
Playwright ~18–20m

About 7.5× faster thanks to auto-wait wiping out Thread.sleep and flaky waits. Zero scenario rewrites, no flakiness.

Auto-wait FTW 🚀 #Playwright #Java

Good Products are Opinionated.

“Every great founder I’ve seen up close, or even from afar, is highly opinionated and they’re almost dictatorial in how they run things.

Also, early-stage teams are opinionated. And the products they build are opinionated. Opinionated means they have a strong vision for what it should and should not do.

If you don’t have a strong vision of what it should and should not do, then you end up with a giant mess of competing features.

@Jack Dorsey has a great phrase: “Limit the number of details and make every detail perfect.” And that’s especially important in consumer products. You have to be extremely opinionated. All the best products in consumer-land get there through simplicity.

You could argue the recent success of ChatGPT and similar AI chatbots is because they’re even simpler than Google.

Google looked like the simplest product you could possibly build. It was just a box. But even that box had limitations in what you could do.

You were trained not to talk to it conversationally. You would enter keywords and you had to be careful with those keywords. You couldn’t just ask a question outright and get a sensible answer. It wouldn’t do proper synonym matching, and then it would spit you back a whole bunch of results. That was complicated. You’d have to sift through and figure out which ones were ads, which ones were real, were they sorted correctly, and then you’d have to click through and read it.

ChatGPT and the chatbot simplified that even further. You just talk to it like a human—use your voice or you type and it gives you back a straight answer.
It might not always be right, but it’s good enough, and it gives you back a straight answer in text or voice or images or whatever you prefer.

So it simplifies what we looked at as the simplest product on the Internet, which was formerly Google, and makes it even simpler. And you just cannot make a product that’s simple enough.

To be simple, you have to be extremely opinionated. You have to remove everything that doesn’t match your opinion of what the product should be doing. You have to meticulously remove every single click, every single extra button, every single setting.

In fact, things in the settings menu are an indication that you’ve abdicated your responsibility to the user. Choices for the user are an abdication of your responsibility. Maybe for legal or important reasons, you can have a few of these, but you should struggle and resist against every single choice the user has to make.

In the age of TikTok and ChatGPT, that’s more obvious than ever. People don’t want to make choices. They don’t want the cognitive load. They want you to figure out what the right defaults are and what they should be doing and looking at, and they want you to present it to them.”

Great breakdown on how to spot real A-players

[Scot Chisholm @scotchisholm]

Want to snag the best talent out there? 

This framework helps cut through the fluff with killer interview questions..

Revealing who’s really got the goods. 

7 best interview questions to hire A-players:

Test for Values
"Which one of our core values resonates with you most and why? What would you do if you worked on a team that behaved oppositely?"

Test for Resilience
"Can you tell me about a time where you faced failure or rejection and were forced to bounce back? What did you learn from the process?"

Test for Independent Thinking
"Walk me through how you'd tackle [insert a real and specific problem] if you were given only [X] limited resources and no managerial help?"

Test for Coninuous Learning
"What are your favorite books/blogs/podcasts on [the subject of the role]? And how do you challenge yourself to keep growing in your field over time?"

Test for Adaptability
"Tell me about a time when an unexpected shift in plans affected your project or role dramatically. How did you adapt to the situation?"

Test for Attitude
How would you deal with a situation where things aren't going well for your team, and people are starting to get discouraged and turn negative?"

Announcing @ChromeDevTools MCP! 🚀

Connect your AI coding agent to Chrome's powerful automation & debugging capabilities with ease.

Key features:

✅ Reliable automation: It can programmatically handle clicks, form fills, dialogs, and page navigation with ease.

✅ Performance insights: Go beyond simple audits. Instruct your agent to record a performance trace and extract actionable insights to optimize your web apps.

✅ Advanced debugging: Empower your AI to analyze network requests, list console messages, take screenshots, and even evaluate scripts in the browser context.

✅ Browser emulation: Easily test different conditions by emulating CPU slowdowns, network throttling, or various screen sizes.

Works well with modern web apps and believe this will unlock new workflows for automated testing, AI-driven debugging, and interactive web development.

And there's much more to come!
