Good Documentation Saves Developers 3 Days of Debugging

Most bugs aren’t caused by bad code; they’re caused by unread documentation. Developers often say, “I’ll figure it out as I go,” but this leads to spending hours debugging something explained in the first 10 lines of the README. For instance, I once spent an hour debugging a CORS issue. The solution? A single line in the documentation: enable credentials in the middleware. Documentation isn’t a chore; it’s the quickest way to understand a library. Good documentation provides guidance on how to use the library effectively, what not to do in production, and the trade-offs the authors considered. Instead of guessing or fighting the framework, you align with it. Reading the documentation for 30 minutes often saves 3 days of debugging. It’s not slower; it’s a shortcut.

I let Claude Code write an entire module last week and did not understand a single line of it. That scared me more than any bug ever has. Claude Code is genuinely impressive. I use it every day. But I have started noticing something uncomfortable in myself and the engineers around me. We are getting faster at shipping and slower at thinking. Here is what I have been observing: 1. We Google less, which means we explore less Searching used to lead to rabbit holes that made us better engineers. 2. We accept AI output without questioning it If you cannot explain the code you commit, that is a problem. 3. Debugging skills are quietly getting weaker Claude Code fixes symptoms. It rarely teaches you the root cause. 4. Junior developers are skipping fundamentals Why learn closures if Claude Code writes the function for you? That mindset is dangerous. 5. We are outsourcing thinking, not just typing There is a big difference between using Claude Code as a tool and using it as a brain. The mindset shift: AI should make your thinking sharper, not replace it. The engineers who will win in the long term are the ones who use Claude Code to move faster but still understand deeply. 🧠 So I want to hear what the community actually thinks. Is Claude Code making us better engineers or quietly making us dependent? Drop your honest take in the comments. I genuinely want to debate this. 👇 If this helped, I would love to hear your experience. #SoftwareDevelopment #ClaudeCode #Programming #TechDebate #EngineeringMindset

Code is disposable. Behavior is permanent. That's the premise behind STDD — Specification & Test-Driven Development. Most teams treat code as the asset and documentation as an afterthought. STDD flips that. The specification and tests are the product. Code is just one possible rendering of that knowledge — and it can be regenerated at will. Here's how it works: → Write a formal specification first (inputs, outputs, rules, invariants, failure conditions) → Derive acceptance cases from that specification → Write or generate tests that verify every rule → Then produce the implementation — by hand, by AI, by rewrite If the tests pass, the implementation is correct. If requirements change, you update the spec, update the tests, and regenerate. The code never accumulates legacy debt because it was never meant to last. This isn't theoretical. I've published the full methodology — manifesto, method, templates, tooling, and a working CI pipeline — as open source. 🔗 https://lnkd.in/gj9jRzwS #SoftwareEngineering #STDD #SpecificationDriven #QualityEngineering #OpenSource

As everybody knows, a lot of code today is generated with the help of LLMs. Code generation itself is rarely the bottleneck. Code review is. Generated patches arrive quickly, but someone still has to read the diff and understand what actually changed. With AI-generated code this can be surprisingly hard. Diffs often mix refactoring, formatting, renames and small logic changes in the same place. Lots of red, lots of green — and it takes time to see what really matters. This made me wonder if reviewability of a diff could be measured. So I started a small pet project on GitHub to explore this idea: https://lnkd.in/eXe3GpFV The idea is to analyze a diff and give feedback that could help restructure the patch — for developers or for LLMs generating the code. Easier diffs → faster reviews. #CodeReview #LLM #SoftwareEngineering #CICD #DevTools

Software engineering has quietly changed… and most people haven’t noticed. What used to take hours of coding, debugging, and testing can now be accelerated with AI tools like OpenAI Codex, Claude Opus, and Claude Sonnet. But here’s the catch 👇 AI doesn’t just need instructions… It needs good instructions. ⚠️ Poor prompting leads to: ❌ Hallucinated APIs ❌ Broken implementations ❌ Security risks ❌ Wasted time and money 💡 The shift is clear: We are no longer just writing code… We are guiding intelligence. The best engineers today are not just coders, They are prompt engineers. 👉 The difference? Bad: “Build an API” Better: “Build a RESTful API in .NET 8 using Clean Architecture with JWT authentication and PostgreSQL.” That’s how you move from: 🧪 Guesswork → 🚀 Production-ready systems 🔥 Key mindset: Be explicit Define constraints Provide context Control the output Because in this new era: 👉 Writing code is optional 👉 Thinking clearly is not 📖 Read more on our blog here: https://lnkd.in/dqNSSxUb

What the top 1% developers will do differently in 2026 Most developers are still optimizing for syntax. That is becoming irrelevant. The shift is already happening: They think in systems, not functions Writing code is no longer the bottleneck. Designing how components interact, scale, and fail is. They move from “frontend/backend” to “architecture” The separation is less valuable now. The real leverage is in decisions like: – data flow – API boundaries – state management – infra cost vs performance trade-offs They treat AI as a compiler, not a crutch AI will generate most of the code. The skill is not writing code — it’s: – giving precise instructions – validating outputs – catching edge cases They prioritize problem clarity over solution speed Average developers jump to implementation. Top developers spend more time defining the problem constraints. They optimize for leverage Instead of asking “how do I build this?” They ask: – should this be built at all? – can this be automated? – can this be reused across products? In 2026, the best developers won’t be the fastest coders. They’ll be the ones who think the clearest. — Curious: what skill are you actively improving this year? #SoftwareEngineering #WebDevelopment #AIinDevelopment #FutureOfWork #TechTrends #Programming #DeveloperMindset #SystemDesign #SoftwareArchitecture #ProblemSolving #BuildInPublic #LearnToCode

Skills are the new source code. Not a metaphor. A thesis. 👇 For decades, source code was the most protected asset in software engineering. We versioned it, reviewed it, guarded it. The quality of the codebase was a genuine competitive moat. That moat is draining. AI agents can now produce production-grade code from a well-formed prompt. When something can be generated on demand, it becomes a commodity. So if the code isn't the differentiator anymore — what is? Human judgement. And the organisations that figure out how to encode that judgement into reusable, versioned Agent Skills will own the next era of engineering advantage. I wrote about why — and what this means for engineering leaders — in my latest article. (See https://lnkd.in/gpx68ubA) Agree? Disagree?

This is not the future but rather the present!! [And it's also true for technical writing!] -> "So what exactly is left? Or as Boris Cherny, the head of Claude Code, put it when we met at Anthropic’s headquarters in January: “What is computation — what is coding?” Then he added, “You can get pretty philosophical pretty fast.” His answer echoed what I’ve heard from pretty much every developer I’ve spoken to: A coder is now more like an architect than a construction worker. Developers using A.I. focus on the overall shape of the software, how its features and facets work together. Because the agents can produce functioning code so quickly, their human overseers can experiment, trying things out to see what works and discarding what doesn’t. Several programmers told me they felt a bit like Steve Jobs, who famously had his staffers churn out prototypes so he could handle lots of them and settle on what felt right. The work of a developer is now more judging than creating. Cherny himself has been through all the layers of abstraction: As a teenager in California, he taught himself a little Assembly so he could write a program that solved math homework automatically on his calculator. Today he simply pulls out his phone and dictates to Claude what he wants the A.I. agent to do; in a sort of Ouroboric loop, 100 percent of Cherny’s contributions to the Claude codebase are now written entirely by Claude. While we talked, his phone was sitting on the table in front of us, and at the end of an hour he showed me the screen: 10 Claude agents had been tweaking the codebase. “I haven’t written a single line by hand, and I’m like the most prolific coder on the team,” he said. “It’s an alien intelligence that we’re learning to work with.”" https://lnkd.in/epK9HxfY #AI #GenerativeAI #LLMs #Programming #SoftwareDevelopment #AIAgents
