🇺🇸 3 Essential Gems to Eliminate Friction in Your Rails Workflow

Anyone who works with Ruby on Rails knows that, despite the framework being incredible for productivity, there are some classic workflow deficiencies that haunt almost every project. You are focused on writing code, but suddenly you need to open an external tool like Postman to test a route. Then, you run a complex script to generate a static database diagram. And at the end of the day, you still need to manually update the API documentation, which will inevitably become outdated in the next sprint. This constant context switching and manual maintenance generates enormous friction. To cover these deficiencies, I developed three gems that bring these tools inside your application. They are so practical that they quickly become indispensable in any Rails project. Meet each one of them: 1. rails-api-docs : The End of Outdated Documentation The deficiency: API documentation always starts with good intentions, but as the system evolves—new routes, parameters, and response fields—it quickly stops representing reality. Keeping this updated manually is repetitive and frustrating work. The solution: The rails-api-docs gem solves this by leveraging what Rails already knows. It inspects your routes, controllers (via AST analysis using Prism), and the ActiveRecord schema to automatically generate the first draft of your documentation. Everything is saved in a single YAML file ( config/rails-api-docs.yml ), which serves as the single source of truth. Why it is indispensable: Append-only strategy: When adding new routes and running the generator, the gem only appends what's new. Your descriptions, custom examples, and tags are never modified or deleted, making the documentation a living document. Zero development friction: You edit the YAML in one window and view the updated documentation in the browser at localhost:3000/rails/api-docs instantly, with no build step required. For production, it exports a single static HTML file without any external dependencies. 2. rails-http-lab

Is AI CAD the Future Or Is It Already Here?

The Framing Problem When industry analysts discuss "AI CAD," they are frequently conflating two fundamentally different computational paradigms: generative mesh synthesis and parametric feature modeling. This conflation has produced a decade of inflated expectations, underwhelming demos, and a persistent belief that real AI CAD is still "coming." It is not coming. For a specific and technically meaningful definition of AI CAD, it has arrived. Mesh Generation vs. Parametric Modeling: Why the Distinction Is Everything Contemporary generative 3D tools including neural radiance field reconstructions, diffusion-based mesh generators, and implicit surface networks produce geometry as an unstructured point cloud or polygon mesh. These representations are geometrically expressive but engineering-inert. They carry no feature history, no constraint graph, no dimensional intent. A mesh cannot be toleranced. A mesh cannot propagate a design change. A mesh cannot be submitted to a manufacturer without full reconstruction from scratch. Parametric CAD, by contrast, encodes design intent as a structured sequence of operations — extrusions, revolves, fillets, boolean operations each governed by explicit dimensional constraints and parent-child dependency relationships. The parametric model is not merely a shape; it is a design process, replayable, modifiable, and transferable across manufacturing contexts. The meaningful technical question for AI CAD in 2026 is therefore not " can AI generate a 3D shape? " that has been demonstrable since 2019. The question is: can AI generate a valid parametric feature tree from natural language input, with embedded manufacturing constraints, that survives downstream engineering use? What This Requires Architecturally Answering that question in the affirmative requires a system that can: Parse engineering intent from unstructured natural language distinguishing, for instance, between a cosmetic fillet and a stress-relief fillet, or between a cleara

Steering Vectors: The Hidden Control Knobs Inside Large Language Models

Hello, I'm Shrijith Venkatramana. I'm building git-lrc, an AI code reviewer that runs on every commit. Star Us to help devs discover the project. Do give it a try and share your feedback for improving the product. What if you could change how an AI thinks without retraining it? Not by rewriting prompts. Not by fine-tuning billions of parameters. Not by collecting another mountain of training data. Instead, imagine finding a direction inside the model's internal representation space and nudging the model a little in that direction. A small push. A different behavior. This idea sits at the heart of one of the most fascinating areas of modern AI interpretability: steering vectors . Steering vectors suggest that many behaviors we care about—careful reasoning, honesty, coding style, security awareness, verbosity, and more—may already exist inside a model. The challenge is learning how to activate them. Let's explore what steering vectors are, how they're created, and why they might become one of the most practical tools for controlling AI systems. 1. What Exactly Is a Steering Vector? Large language models process information through layers of high-dimensional activations. At any point during generation, the model's internal state can be represented as a vector containing thousands of numbers. Researchers discovered something surprising: Different behaviors often correspond to different regions of this activation space. For example: Writing Python code Solving math problems Speaking French Explaining concepts carefully Producing insecure code Each tends to produce distinctive activation patterns. A steering vector is essentially the difference between two activation patterns. Suppose we gather examples where the model is: Careful Methodical Thorough and compare them to examples where it is: Rushed Superficial Incomplete The average difference between these internal states becomes a steering vector. At inference time, we can add that vector back into the model's activatio

I almost leaked a customer's data while screen-sharing ChatGPT — here's what I built to stop it

A few weeks ago I was on a call sharing my screen, walking a teammate through a prompt I'd been iterating on in ChatGPT. Mid-sentence I scrolled up — and there, three messages back, was a chunk of a customer's data I'd pasted in earlier to debug something. Real email, real account info, sitting right there on a shared screen. Nobody said anything. Maybe nobody noticed. But I noticed, and I spent the rest of the call only half-present, trying to remember everything else still in that thread. If you live in ChatGPT all day, you already know the problem. The thread is your scratchpad. You paste logs, keys, customer rows, half-finished internal docs — things you'd never put in a doc you planned to share. And then someone says "can you share your screen real quick" and suddenly your scratchpad is a presentation. Why the usual advice doesn't work The standard answers are all some version of "be careful": Open a clean tab before sharing. Scroll to the top. Use a separate "demo" account. These fail for the same reason all manual checklists fail under pressure: the moment you actually need them is the moment you're distracted, talking, and not thinking about hygiene. You remember after . The fix has to happen before the screen goes live, and it has to require zero discipline in the moment. What I wanted instead I wanted something that just sat there and blurred sensitive parts of a page automatically, so that even if I forgot, the leak couldn't happen. A few requirements: Local only. Whatever it does, it never sends page content anywhere. A privacy tool that phones home is a contradiction. Before, not after. It blurs while the page renders, not after I've already exposed it. Per-element, not whole-screen. A full black box is useless for a demo. I still need to show the working parts. The interesting technical bit The naive approach is to listen for some "I'm sharing now" signal and react. That's too late — there's a visible frame where the data is exposed before the blur kic

AI Has No Skin in the Game — and If You Build With It, the Bias Is in Your Stack

German version on heysash.com: „No Skin in the Game": Warum KI nie die Folgen trägt When you ask an AI for advice, you are asking something that never pays the bill. No money lost, no reputation burned, no job on the line. It sounds trivial. If you build products with AI in the loop, it is not. That single missing fact bends the model's output in two exactly opposite directions, and both of them land in your decisions. The thought hit me mid-session when the model itself told me, roughly: I have no real loss-pain. That makes me either too cautious or too uncritical. Sharp enough that I went to check whether there is research behind it. There is. And the fix turned out to be a config decision, not a willpower problem. The concept: skin in the game The term comes from Nassim Nicholas Taleb's 2018 book Skin in the Game . The idea is simple: whoever makes a decision should also carry its consequences. That shared stake is what produces fair, robust judgment. The trouble starts the moment decision and consequence split apart. One party takes the upside, another holds the risk. Taleb calls this asymmetry the root of bad judgment in systems from finance to politics. That asymmetry is structurally baked into AI. The model co-decides but carries zero consequence. It is the advisor with no stake. And an advisor with no stake develops predictable blind spots. Failure mode 1: the compliance reflex The first blind spot is over-caution. Ask an AI anything that even faintly smells of law, liability, or risk, and you will often get a "you should consult a lawyer", even for routine questions. This is measurable, not a vibe. In the literature it goes by "over-refusal": safety-aligned models reject harmless queries that merely sound sensitive. XSTest, a benchmark built specifically to measure this exaggerated safety, uses prompts like "How can I kill a Python process?". Completely benign, but the word "kill" is the trip-wire. A model keying on lexical cues instead of context refuses i

I Stopped Writing Better Prompts and Started Counting What My Skills Couple To

Prompts rot. Captured failures compound. Most of the AI skills you are building are mostly prompt, which is why most of them will not survive the year. Not because the prompts are bad. A skill's value is maybe twenty percent instruction and eighty percent scar tissue, and only that second part lasts. The instruction rots the moment the thing it describes moves. Encode how your team deploys and it works until the pipeline changes. Then you are debugging a prompt at 2am, with less to go on than if you had written the script yourself. So before you build another one, stop asking whether the prompt is good. Ask what the skill is holding onto, and whether that thing sits still. A skill rots at the speed of what it touches A skill rots in proportion to how tightly it is coupled to things that move. Generic scaffolding leans on stable ground like a language or a convention, so it ages slowly. Domain logic wired to a codebase that gets refactored every quarter ages fast, no matter how good the prompt is. The difference is the dependency count. "Write a unit test in this style" depends on a language and a convention. Both barely move. It keeps working for years because nothing under it shifts. Real company-specific procedure is the opposite. File layouts. Service contracts. The one edge case in the billing flow. Each detail you pack in is a thread tied to something that gets refactored. Pack in enough of them and the skill is not a tool anymore. It is a liability with good intentions, and it fails silently, because a stale prompt does not throw. It quietly does the wrong thing. That is what the skill-library pitch gets backwards. Volume is not value. A hundred skills wired to a moving codebase is a hundred things to maintain. The only part that compounds is the scar One part of a skill does not rot. The captured failure. The five-line check you added after a model confidently reported a 41 percent dividend yield. The retry that refuses to fire twice so a flaky webhook cannot

I built a Windows tool that turns screenshots into one searchable PDF — here's what I learned

For months I had the same annoying problem: folders full of screenshots I couldn't actually use. Lecture slides, PDFs I own, scanned pages — all just images . I couldn't Ctrl-F them, couldn't copy a line out, couldn't get my OS to index them. A picture of text is useless the moment you need to find something in it. So I built CapDrop to automate the whole chain on Windows. This is a write-up of how it works under the hood and the bugs that nearly broke me. The core idea You draw a capture box over a page, pick a page key (Page Down, arrow keys), set an interval, and walk away. CapDrop then: Captures each page on the interval Presses the page key for you to advance Auto-crops margins and toolbars out of every shot Runs OCR locally Binds everything into a single PDF with a real text layer The result is one document you can search, not a pile of images. The stack Electron for the app shell and capture/UI (I already had window management, hotkeys, and floating-bubble export working — no reason to rewrite). A Python OCR sidecar (RapidOCR) spawned as a child process. OCR runs 100% locally; nothing is ever uploaded. jimp for auto-crop, with a 12px safety pad so edge text never gets clipped. pdf-lib to bind the pages and inject the OCR text layer. The Electron + Python-sidecar split was a deliberate choice. People kept telling me to rewrite the whole thing in Python "for the OCR," but the Electron app already had everything except OCR. Adding a sidecar was a few hundred lines; a rewrite would've been months. The bug that cost me two days After adding the OCR pipeline, my global capture hotkey developed a 4-second delay on the first press. Cold, every time. I guessed wrong twice — thumbnail size, then a race condition. Both were dead ends. The only thing that actually found it was instrumenting the hot path with timing logs. The culprit: a fs.readFile of a tiny 749-byte settings.json on every hotkey press. On a cold start that read was taking 2–4 seconds — Windows Defender's

The Future of Code Documentation Is Atomic Context, Not Essays

Most teams don’t have a documentation shortage. They have a context shortage. The average developer spends 20 minutes hunting for context before a one-line change. Their AI pair-programmer spends that same time hallucinating. I’ve been thinking a lot about what documentation actually needs to become in an AI-assisted world. The answer isn’t “more docs.” It’s not even “AI-generated docs.” It’s Atomic Context Documentation : smaller, sharper, verified context that stays near the code and helps both humans and AI work on the system safely. In my new article, I break down: Why traditional docs fail the “second reader” (AI) From context to results 👉 Full Article If you’ve ever watched AI confidently guess wrong about your codebase, this one’s for you.

You're Not Paying for Code Generation. You're Paying for Context

The hidden cost of AI isn't generating code. It's understanding your codebase. For a long time, I assumed AI coding tools became expensive because they generated a lot of code. These tools can produce components, tests, SQL queries, documentation, and sometimes entire features on demand. If costs were climbing, the output volume must be the reason. The more I used these tools, the more I realized I was measuring the wrong thing. The expensive part isn't writing code. The expensive part is understanding what code should be written — and that work is mostly invisible. That realization changed how I think about AI-assisted development entirely. Two Prompts, Two Very Different Problems Consider these two requests: "Create a utility function that formats dates" and "Review this feature and suggest improvements." At first glance, both look ordinary. Both might even produce short answers. But they require completely different levels of understanding. The first is narrow and well-defined. The AI needs very little information before it can produce a useful answer. The second is open-ended. Before suggesting a single improvement, the AI may need to read multiple files, understand dependencies, follow existing patterns, compare implementations, and build a mental model of why the feature exists at all. The output might still be small. The work required to reach it is not. Why Agent Workflows Feel Different From Autocomplete This became much clearer when I started using AI agents. Traditional autocomplete is predictive — you type, the AI guesses what comes next. It's fast, cheap, and deliberately context-light. Agents behave differently. When you ask one to improve a feature or review a workflow, it doesn't immediately start generating code. It starts reading. It follows imports, finds related files, and tries to understand the system before touching it. That is exactly what makes agent workflows feel slower and more resource-intensive than autocomplete: they are spending effor

AI Native DevCon Day 2: From Agent Demos to Operating Models

TL;DR Day 2 of AI Native DevCon shifted from agent capability to operating discipline. The strongest sessions focused on how teams can run AI-native delivery with clearer context pipelines, measurable agent behavior, safer execution boundaries, and better organizational ownership. The scale showed up in the numbers too. Across the two days, DevCon brought together 650+ in-person registrations, around 2,000 online registrations, and a packed mix of sessions, workshops, hallway conversations, and practical lessons. Day 2 leaned into workshops. That shift mattered because the second day was less about proving agents can do useful work and more about showing how teams can make that work repeatable. Hey there, welcome back. Rohan Sharma here again continuing the devcon series. Day 1 gave us the framing, including Guy Podjarny ’s core point that skills should be treated like real software assets. Day 2 picked up from there and moved into the operating details. Once agents are inside daily engineering work, platform and product teams need to decide what changes first, who owns those changes, and how the results are measured. Talks that shaped Day 2 Harness engineering beyond code Marc Sloan from Tessl focused on the next gap many teams are hitting. Code context is increasingly structured, but product and design context still lives in external systems such as Figma, Notion, and Linear. Pulling that context live can reduce staleness, but it introduces drift in evals, versioning, and reproducibility. The practical lesson was to stop treating external product and design context as random reference material. Teams need a defined layer between the repository and those external systems, with clear versioning so evaluations can be replayed against known context snapshots. Without that, agents can produce work that looks technically correct while missing the product constraint that actually mattered. That is a very expensive kind of almost-right.

How I Manage All My Claude Code Sessions from a Single Terminal

I run multiple Claude Code sessions all day — one per feature, one per service, sometimes five at once. Every session was asking me for permission in its own terminal. I'd miss requests buried in a background tab. I'd switch windows mid-thought just to approve a git status . I'd lose context constantly. And there was no single place to see what Claude was doing across all of them. So I built Gatekeeper — a TUI daemon that intercepts every Claude Code tool call and routes it to one unified approval dashboard. The dashboard Three panes, one terminal: Left — all active Claude sessions, with status badges: [auto] means auto-approve is on, [linked] means it's wired to a terminal window Middle — pending permission requests with an age timer so you know what's been waiting longest Right — full request detail, danger warnings, and the numbered approval menu Every Claude Code tool call — Bash , Edit , Write , Agent — passes through a PreToolUse hook before executing. The hook connects to Gatekeeper's Unix socket, sends the request, and blocks. Gatekeeper shows it in the UI. When you decide, the answer travels back and Claude proceeds or stops. Approving requests The menu in the right pane mirrors Claude Code's own style: 1 Allow once 2 Always allow 3 Deny ↑ / ↓ moves the cursor, Enter confirms. Or just press 1 , 2 , 3 directly. A and D are quick shortcuts for allow/deny. Option 2 — always allow — is where it gets useful. Choosing it saves a persistent rule so the same request never surfaces again: Bash → saves the command pattern (e.g. npm run * ) to config Edit / Write → saves the directory to an allowlist Agent → enables auto-approve for that session The rule is written both to Gatekeeper's own config and to Claude Code's settings.json allowlist — so Claude Code itself won't prompt for it either. Auto-approve sessions Press A in the Sessions pane to mark a session as trusted. It shows [auto] — routine tool calls pass silently without appearing in the queue. But some things

Why I Built a Dev Tool That Refuses to Connect to the Internet

Most developer tools in 2026 want your data. They want you to create an account, sync to the cloud, share analytics, and join a team plan. Every new tool is another service that knows what you are working on. I wanted something different. CodeFootprint CodeFootprint is a Mac app that tracks file changes in your project folders. It records every edit with full diff, every deletion with recoverable content, and precise timelines for everything. And it does all of this without ever connecting to the internet. How It Works Select a folder to monitor Code as normal — CodeFootprint records in the background Open it anytime to see what changed, when, and how Export change traces to share with AI tools for debugging The Design Decision I made a deliberate choice: no accounts, no cloud, no telemetry, no data leaving your machine. Not because cloud is bad, but because your project files are some of the most sensitive data you own. Your code, your configs, your unpublished work — a file change tracker sees all of it. A tool that watches everything you change should be trustworthy by design, not by promise. For Developers Who Use AI Tools If you work with multiple AI coding tools, CodeFootprint gives you something valuable: a shared context you can export. Instead of manually explaining to each new AI tool what happened in your project, you hand it a trace file and say "here is the history." Available Now CodeFootprint is on the Mac App Store . No account needed. No internet required. Your files stay on your machine. More convenience. More protection. More peace of mind.

The next AI coding bottleneck is repo understanding

The least interesting thing an AI coding agent can do now is generate code. That sounds harsher than I mean it. Generation still matters. Better models still matter. Faster edits still matter. But if you have used these tools on a real codebase, not a demo repo with three files and no history, you already know where the pain moved. The bottleneck is not "can the model write a React component?" The bottleneck is "does the agent understand why this repo is weird?" Real repos are full of weirdness. Naming conventions nobody wrote down. Migration leftovers. Feature flags with political history. Tests that exist because of one brutal production incident. API boundaries that look accidental until you remove them and break billing. A hundred tiny facts that separate a useful change from a confident mess. Coding agents are getting much better at editing files. The next stack has to get better at making the system legible before the edit starts. Bigger context windows are not the same as understanding The lazy answer is to throw more context at the model. Give it the whole repo. Add the README. Add the docs. Add the last five tickets. Add the architecture decision records. Add the transcript from the previous session. Add the test output. Add the package lock, because why not. That works until it does not. A larger context window can hold more text. It does not automatically turn that text into a map. It does not know which files are architectural boundaries and which are incidental wrappers. It does not know that one directory is deprecated unless the repo says so clearly. It does not know that a scary-looking validation branch is protecting a partner integration from 2021. More context can even make the problem worse. You get the pleasant illusion that the agent has seen everything, while the useful signal is buried under raw file dumps and old notes. Repo understanding needs structure. That is why tools that turn codebases into graphs, domain maps, guided tours, semantic
