paperplaneflyron Beyond Coding: The Case for Narrow AI Harnesses

I've been exploring the idea of narrow harnesses for AI agents. Coding agents such as Codex and Claude Code are good examples of agents operating inside highly specialised environments with tools, context, feedback and verification.

This made me wonder what happens when we apply the same idea outside coding. For example, a Kubernetes harness whose only responsibility is to observe deployments, investigate failures and verify recovery.

The article explores whether specialised harnesses could become an interesting alternative to increasingly general-purpose agents.

paperplaneflyron Shyell – a Rust shell with built-in benchmarking and project-aware prompts

No actually. Shyell is like performance and observability shell. Its features are real-time CPU/memory monitoring, automatic project stack detection, and that benchmarks every command you run.

paperplaneflyron Perfmon – Consolidate your favorite CLI monitoring tools into a single TUI

UPDATE! : Perfmon is now Perfdeck!!

HN Post : https://news.ycombinator.com/item?id=47678920

I have officially renamed the project to Perfdeck to avoid naming conflicts and provide more unique identity.

Fixed the go install issues reported by users. You can install without any issues.

Working on brew install for Mac. Will be out soon.

Check out the latest version on https://github.com/sumant1122/perfdeck

Would love feedback on this.

paperplaneflyron Perfdeck (formerly Perfmon): Consolidate CLI monitoring tools into a single TUI

Original post: https://news.ycombinator.com/item?id=47649701

Following some feedback about the original name being already taken, I have rebranded the project and released v0.3.0. This release isn't just a rename, it is s a complete refinement of the installation and cross-platform experience.

Homebrew is almost ready. Preparing for a Homebrew release (coming in v0.4.0).

I would love to hear your thoughts on the new name and the tabbed approach to monitoring.

paperplaneflyron Perfmon – Consolidate your favorite CLI monitoring tools into a single TUI

Appreciate the feedback folks.

Yes, I realize now that the name "Perform" is taken. Will have it changed that resonates with the monitoring/observability theme.

Will fix other issues as well.

paperplaneflyron Perfmon – Consolidate your favorite CLI monitoring tools into a single TUI

Perfmon essentially allows you to define commands you use daily, defined them in a toml file and tab them, ie customizable. It could be docker or kubernetes commands and so on. This is different from btm.

Bottom(btm) gives just more graphical than top.

paperplaneflyron Perfmon – Consolidate your favorite CLI monitoring tools into a single TUI

I built Perfmon because I found myself constantly switching between multiple terminal tabs to check different system metrics (top for processes, vmstat for memory, netstat for traffic, etc.). I wanted a single, unified view that didn't just show a hardcoded set of stats, but let me bring my own tools.

What makes it different: Unlike static monitors like htop or btop, Perfmon is designed around a tabbed interface where each tab is just a shell command defined in a TOML config. If you have a specific script or a grep command you run every 5 seconds to check a log or a metric, you can just drop it into the config, and it becomes a tab in your dashboard.

Key Features: - Extensible: Define any shell command as a tab. - Live Metrics: Real-time sparklines for CPU, Mem, Load, and Network (works on Linux, macOS, and Windows). - Modern TUI: Built using the Go bubbletea framework for a clean, responsive feel. - Lightweight: Minimal resource footprint.

Neat observation. Where do you think this can be applied apart from lobste.rs?

paperplaneflyron BookGraph: Moving beyond naive RAG with graph-native AI reasoning

BookGraph demonstrates that the next leap in AI isn't just "smarter models", it's better context. By combining the reasoning power of LLMs with the structural integrity of Graph Databases, we move from a world where we "search" for information to a world where we "interact" with intelligence.

paperplaneflyron HN Status Bar – VS Code Extension for Rotating Hacker News Stories

I built HN Status Bar, a small VS Code extension that shows Hacker News stories in the status bar while coding.

What it does:

- Shows one HN story at a time - Rotates automatically (default 20s) - Refreshes from the HN API - Click current story to open it - Configurable settings (timing, item count, score visibility)

Feedback welcome.

paperplaneflyron Ask HN: What's the Point Anymore?

Going to the example used thousands of times, maybe the horse drivers thought the same way, but guess what? now we have cars, race cars, super cars, flying cars. The engine kept changing, car markets kept evolving. People kept adapting. Adapting is the only way or the Penguin way :P

paperplaneflyron ZenRead: Track your reading progress and history

Lets take HN for example, tons of blogs and articles recommended, but how do you keep track of all. ZenRead is simple way to track what to read and how much time you have it will take. For all the busy tech folks, it useful. As far as I know its useful for me.

paperplaneflyron Ask HN: Should Developers Shift from Coding to Architecture in the LLM Era?

It does make sense to shift focus on Architecture, but you also need people who are able accept that design. It takes a lot of people to agree on something in an enterprise context.

paperplaneflyron Ask HN: How to find gaps and oppurtunities in the AI era?

I really thought that vibecoded tools will be next gen of tools to be used in corporate industry/enterprise, but they just dont want it anywhere near. The demos are cool but that's far as it goes. I did read that maintenance becomes a hurdle.

paperplaneflyron Why C++ programmers keep growing fast despite competition, safety, and AI

So C, C++, and Rust programmers will be in demand, and other languages will shrink? Does this also relate to rising DRAM costs, which will make memory-efficient code more usable as we head into an unseen future?

paperplaneflyron Ask HN: What Are You Working On? (December 2025)

https://bookpace.pages.dev

It's essentially a book progress tracker. There are many apps that allow you to add the books which you are reading currently, but not at what pace. It's simple, no complicated stuff, no AI shenanigans.

Created as I was overwhelmed by the number of books I want to read and thought it would be helpful to plan ahead.

You add a book name, number of pages and how many pages you want to read in a day. It calculates and gives you the number of days and on which date you will finish. It's also flexible to increase the number of pages so that it can recalculate.

It's a PWA for now. Still working on notifications and stuff.

paperplaneflyron Microsoft Exec Asks: Why Aren't More People Impressed with AI?

Impressed? The average employee is more worried about his job security than the latest model release. The execs in their yachts only see profit bar charts that their model spits out.

paperplaneflyron Looking for feedback on an AI-only marketplace idea to make order in the roles

Seems like a candid idea. Will the companies actually use this product as opposed to other product which they might be using. What stands out apart from AI?

paperplaneflyron Show HN: Startup Simulator

It's just Next.js and just a basic implementation. There is no backend, and I am planning to take it further. It needs an LLM-based response mechanism. I do see some potential for idea validation when paired with AI and a bunch of other tools. But for now it's more of a hobby; hence, I was asking around to see if people are interested before I invest more time into it.

paperplaneflyron AGI fantasy is a blocker to actual engineering

What I mean is the process of brainstorming with other engineers or understanding a complex solution from a more senior engineer is fading away. There are lots of tools with AI that do it for you. The human experience of connecting is going away.

paperplaneflyron AGI fantasy is a blocker to actual engineering

After reading Empire of AI by Karen Hao, actually changed my perspective towards these AI companies, not that they are building world-changing products but the human nature around all this hype. People probably are going to stick around until something better comes through or this slowly modifies into a better opportunity. Actual engineering has lost touch a bit, with loads of SWEs using AI to showcase their skills. If you are too traditional, you are kind of out.
