Google Calendar’s API now exposes working hours and makes agents declare themselves. Here’s why both matter, and what building Calendrz taught me about them.

Your App’s Next Front Door Is Someone Else’s Chat Window
Bubble showed its no-code builder working inside ChatGPT and Claude. If even UI-first products now meet their users in a chat window, agent experience is becoming the UX that matters, and tool descriptions are the new UX copy.
Should Your AI Agents Get an Employee ID?
SK Telecom now gives its AI agents employee IDs, supervisors and retirement criteria. Strip away the marketing and what’s left is a lifecycle for agents, which most companies are missing. Here’s how we handle it in Calendrz.
Your AI Agents Now Run on a Grid With a Dimmer Switch
Voters turned down data centres in all but one of 41 ballot measures, and OpenAI answered with cheaper power promises, a grid dimmer switch and a new name. The name is the least interesting bit: the compute your AI agents run on is now interruptible, and engineering teams should plan for it.
Five Engineers Rebuilt X.com With AI Agents. Should You Rewrite Too?
Five engineers and their AI coding agents rebuilt the x.com web app in under six months. “Never rewrite from scratch” used to be gospel, but when writing code gets cheap, the hard part moves to the plan and the rollout. Here’s how that played out when I chose to build the Calendrz mobile apps natively, twice.
Wix Hands Your Site to Claude Code. The Lock-In Just Moved.
Wix Studio Two exports your site as React for Claude Code or Cursor, and Readwise opens your library to agents through MCP. Read the small print, though: both open the edges to your agent and keep the core. The lock-in hasn’t gone, it moved, and CTOs should ask what still calls home.
Interpolative Software: Where Your AI Agent Still Needs You
Ben Congdon splits software into interpolative (agents nail it from a few sentences) and novel (fighting uphill). Building Calendrz showed me exactly where that line runs, and why the bits you have to explain are the ones worth building.
Your AI Agent’s Tests Are Green. That Proves Less Than You Think.
A founder rebuilt his whole platform alone with Claude Code, and his tests stayed green for weeks around a pigeon that never existed. When the agent writes the code and the tests, green proves less than you think: here’s what I’d check on Monday morning.
Of AI Agents, Code Mode and the One Tool to Rule Them All
Agents are collapsing their tool catalogues into a single exec tool and writing code against your APIs. Having built an MCP server with 30+ tools for Calendrz, I think that makes your tool design more important, not less, and privacy has to live in the tools.
Daylight Saving Time: Store the Zone, Not the Offset
Europe and the US changed their clocks a week apart, and calendars everywhere got confused. Why storing a time zone id beats storing an offset, what it means for distributed teams, and why it matters even more now that agents book meetings.
