Show HN: Yeah Another Htop for Agents

juanpabloaj — Wed, 08 Apr 2026 15:28:33 +0000

I was looking for a small option for ckeck how many agents are running, and what where they doing. Even when I didn't launch them, for example when claude calls codex the reduce the session usage of claude.

Maybe other names could have been atop (but it exists) or yaat (yeah another agent top).

New comment by juanpabloaj in "Take better notes, by hand"

juanpabloaj — Mon, 30 Mar 2026 21:02:06 +0000

I love to use a paper notebook for fast notes, random thoughts, and to capture tasks (something similar to a GTD inbox). With it, I use a small system of symbols (some degree of similarity with the bullet journal method).

The only issue with paper is the edition. My solution has been to use a compact, slim ring binder with a notebook-like feel. If required, you can move sheets to reorganize content, move the most important ones to another place, etc. Until now, the best alternative that I have found is the Kokuyo Campus Smart Ring Binder.

Show HN: Hacker News comments summary to telegram

juanpabloaj — Mon, 30 Mar 2026 14:50:05 +0000

Usually, when I check Hacker News and the thread has too many comments, I use a llm to summarize them, and probably some people do the same.

To the summaries, I'm using the free tier of Google Gemini. I'm going to continue with the channel alive main while I have free tokens in Gemini.

a small weekend project.

juanpabloaj — Mon, 09 Mar 2026 18:27:03 +0000

No practical code example, sorry. The post is based on my own experience using agents, and I haven't reached a reusable generalization yet.

That said, two cases where I noticed the pattern:

Meal planning: I had a weekly ChatGPT task that suggested dinner options based on nutritional constraints and generated a shopping list (e.g. two dinners with 100g of chicken -> buy 200g). After a few iterations, it became clear that with a fixed set of recipes and their ingredients, a simple script generating combinations was enough. The agent's reasoning had already done its job — it helped me understand the problem well enough to replace itself.

QA exploration: I was using an agent to explore a web app as a QA tester. It took several minutes per run. After some iterations, the more practical path was having it log its explorations to a file, then derive automated tests from that log. The agent still runs occasionally, but the tests run frequently and cheaply.

Regarding your point about tasks that need individual reasoning every time — I think you're right, and that's actually the core of the idea. Not every task matures into a script. Extracting structured data from images probably stays deliberative if the images vary significantly. The cycle only applies to tasks that, after enough repetitions, reveal a stable pattern. The agent itself is what helps you discover whether that pattern exists.

Thanks for the quote. Reading it, I can feel how a Tsutomu Nihei or Giger atmosphere envelops me.

These past weeks I finally organized some ideas I'd been sitting on and wrote two posts:

New comment by juanpabloaj in "Cognitive Debt: When Velocity Exceeds Comprehension"

juanpabloaj — Sat, 28 Feb 2026 18:39:31 +0000

> The second is absorption: mental models form, edge cases become intuitive, architectural relationships solidify into understanding. ... . The friction of implementation creates space for reasoning.

> This gap between output velocity and comprehension velocity is cognitive debt.

I have felt that lack of absorption during the last months, adding doomscroolling to the equation, I have felt how my thinking is disappearing.

I tried to speculatively expand that idea in this post
