Show HN: Email for Agents with 1 Prompt

Hacker News - Sun, 07/19/2026 - 8:50am

Hi HN!

I created Sente. It gives your agents email capabilities with a single prompt. Agents can create email addresses and have web-hooks for incoming emails and API endpoints for sending emails and replies. Would like to know what you think about this and generally about agents having identities.

Ask HN: Guidelines on GPT 5.6 Sol steering

Hacker News - Sun, 07/19/2026 - 8:48am

I converged on these principles in my work with Sol so far:

Let Sol medium/high propose and implement minimum viable solution without overengineering and overthinking.

Use XHigh/Max/Ultra sparingly for hardest most complex workloads/advisory. (For Ultra I found it works best for me, when it had to control/supervised multiple complex lanes/subagents simultaneously within same high level strategic context).

Curious to hear what solutions on properly steering and guiding Sol variants have y'all found and use, alongside with your most used variants, and these variants you barely touch/don't use.

PS: I'm not talking about Terra and Luna at all, as I found them to be inferior to Sol variants for my workloads (slower, dumber, not that cheaper etc.)

Show HN: Subrust, a no_std, no alloc Subset-of-Rust interpreter

Hacker News - Sun, 07/19/2026 - 8:48am

I needed to run user scripts for an app, and decided to use a subset of Rust as the scripting language. I do not expect a typical user to write the script directly, a local LLM will handle it. The interpreter can be bootstrapped in a C-free path from a tiny 229 bytes seed, and self-hosts. The code was written by Claude Code (Fable/Opus) under my supervision, in a few days, which I found impressive.

Show HN: Regularly, hand-picked daily logic and number puzzles, no ads

Hacker News - Sun, 07/19/2026 - 6:58am

Hi HN. I wanted to present to you Regularly (https://regularly.co), a daily logic/math puzzle website I made to scratch my own itch: can we have a fun and engaging puzzle app that doesn't eventually devolve into an iap blockaded mess? For background, a few years ago I released my first daily puzzle (Countable), which I made for my then-girlfriend (now wife) and me to play over morning coffee. One marriage and four games later, the full Regularly set was born: with no ads, no sign-up, no iaps. It spread by word of mouth and a few hundred people now play each day.

Our business model is simple: the daily puzzles will always be free (without ads). At some point I may charge a small amount to access and play the back catalogue, but the day's puzzles stay free forever. As with many other websites, a fresh puzzle set drops every morning. However, unlike those websites, every puzzle shown is hand-picked rather than whatever we can make, and we really focus on getting the difficulty right. We watch how real players actually perform each day (for transparency, we track games started vs games completed to do this) and keep re-tuning our difficulty to maximise engagement. The aim is that every morning's set sits in the zone where you have to think but you aren't stumped.

I recently revamped the iOS app, and would love your opinions (sorry, there's no Android version for now). I commute into work each morning on the tube, and one of my personal gripes with a lot of apps has become how they require a constant internet connection. With the iOS app, once the initial screen is loaded, every puzzle game is playable.

Web: https://regularly.co iOS: https://apps.apple.com/app/id1617532286

If you like Queens or Star Battle, start with Kingly. If you're a numbers person or a romantic, Countable. Floored and Paths are both super fun and iterative (a lot of back and forth).

Happy to answer any questions!
