Coding Agents Evolved. Our Repositories Didn’t.

Why giant AGENTS.md files may be wasting context, hurting maintainability, and making AI-assisted development harder to scale. A few years ago, for many developers, using AI for software development meant copying a small piece of code into a chat window. We would ask for a refactoring, copy the response back into the editor, run the tests ourselves, and return to the chat when something failed. Coding agents changed that workflow. Tools such as Codex, Claude Code, and others can now explore an entire repository, modify multiple files, execute commands, run tests, and iterate on failures. Coding agents turned code assistants into tools capable of executing multi-step software development tasks. But most repositories were not designed for this new kind of contributor. The repository became part of the agent's working context A coding agent needs much more than source code. It may need to understand: the project architecture; dependency boundaries; coding conventions; test strategy; build commands; local environment requirements; validation steps; security restrictions; the definition of done. A common solution is to place these instructions inside files such as AGENTS.md , CLAUDE.md , or other agent-specific configuration files. This works. I have been doing something similar in my own projects for a while. But as the repository grows, the instruction file grows with it. Eventually, a single file may contain thousands of lines covering unrelated concerns: Architecture Testing Environment setup Coding standards Infrastructure UI conventions Validation Release workflows Definition of done At that point, the file is no longer just a set of agent instructions. It has become an informal repository operating manual. The monolithic context problem A large AGENTS.md has an obvious advantage: the agent knows where to find it. But it also creates several problems. It is difficult for humans to navigate These files are not only for agents. Developers also need to read, review, m

Cursor Keeps Skipping Rate Limits on Login Routes (CWE-307)

TL;DR I checked 50 AI-generated login endpoints. Zero had rate limiting. Attackers can brute-force credentials at full speed against these routes. Adding a rate limiter takes four lines and one npm install. I asked Cursor to build a login route for a side project last month. Email, password, JWT back on success. It worked first try, passed my manual tests, and I moved on to the next feature. Three weeks later I ran a load test against it out of curiosity and hit the endpoint two thousand times in under a minute. Not one request got throttled. That's when I started pulling apart every AI-generated auth route I could find, mine and other people's open source side projects, and the pattern held everywhere I looked. The models write correct authentication logic and completely skip rate limiting, because rate limiting isn't part of "does this login work," it's part of "does this login survive contact with an attacker." The vulnerable code (CWE-307) Here's roughly what Cursor and Claude Code hand you when you ask for a login route: // ❌ No rate limiting - CWE-307: Improper Restriction of Excessive Authentication Attempts app . post ( ' /api/login ' , async ( req , res ) => { const { email , password } = req . body ; const user = await User . findOne ({ email }); if ( ! user || ! ( await bcrypt . compare ( password , user . passwordHash ))) { return res . status ( 401 ). json ({ error : ' Invalid credentials ' }); } const token = jwt . sign ({ id : user . id }, process . env . JWT_SECRET , { expiresIn : ' 1h ' }); res . json ({ token }); }); Password hashing is fine. JWT signing is fine. But nothing stops a script from hitting this route as fast as the network allows. No lockout, no delay, no cap on attempts per IP or per account. A credential-stuffing list with ten thousand leaked passwords runs against this endpoint in seconds. Why this keeps happening Rate limiting lives outside the function the model was asked to write. The prompt is "build a login endpoint," and it re

How to Scrape Airbnb Listings and Prices in 2026 (No Code Required)

Heads-up: this post references a tool I built. It's a genuinely useful walkthrough either way — the technique applies to any Airbnb scraping project. If you've ever tried to scrape Airbnb, you already know the two walls you hit: the pages are rendered by JavaScript, and Airbnb aggressively blocks datacenter IPs. Below is the reliable way to get clean Airbnb data in 2026 — listing prices, ratings, coordinates, and discounts — without running a headless browser or babysitting proxies. The key insight: Airbnb ships its data in the HTML You don't need to render the page. Every Airbnb search response embeds the full result set as JSON inside a <script id="data-deferred-state-0"> tag. Parse that and you get structured data straight away — no DOM scraping, no selectors that break on the next redesign. The path to the results is: niobeClientData[*][1].data.presentation.staysSearch.results ├── searchResults[] // ~18 listings per page └── paginationInfo.pageCursors[] // all page cursors, upfront Each listing carries a base64-encoded ID in demandStayListing.id (decode it, take the segment after the last colon, and you have the numeric listing ID for airbnb.com/rooms/<id> ), a price line with discounts, avgRatingLocalized ("4.95 (123)"), and GPS coordinates. The two gotchas Datacenter IPs get blocked. You need residential proxies. If a response comes back without the data-deferred-state marker, you've been served a bot check — rotate to a fresh IP and retry. ~270 result cap per search. Airbnb won't paginate past ~15 pages. To cover a whole market, split into narrower searches (by price band or neighborhood) and dedupe by listing ID. The no-code way If you'd rather not maintain proxy pools and parsers, I published an Airbnb Scraper on Apify that does exactly the above. Paste a location or a full Airbnb search URL (every filter is honored), and get flat JSON/CSV back. curl -X POST "https://api.apify.com/v2/acts/ethanteague~airbnb-scraper/run-sync-get-dataset-items?token=YOUR_TOKE

Building Dot Connector

a local, Claude-powered brain-assistant for solopreneurs I kept losing good ideas — not because I forgot to write them down, but because nothing ever went back and connected them. A task on Monday, an idea on Wednesday that was secretly the same problem, a question on Friday that contradicted something I'd decided two weeks earlier. All of it just... sat there. So I built Dot Connector : a small local app where every capture is a "dot," and every few captures, Claude reviews the stream against a standing memory and surfaces three things — non-obvious connections between notes, contradictions with what you said before, and open loops you haven't closed yet. The architecture is deliberately simple. It's Express + vanilla JS, no build step, no account system. Every capture gets a cheap, fast Claude call for auto-tagging. Every 3rd capture triggers a deeper "sweep" — a second Claude call that looks at recent captures alongside standing memory and open loops, and returns structured updates: new memory facts, dot-connects, contradictions, and open-loop resolutions. Why local-first. no server of my own, notes never leave your machine except the direct calls to Anthropic's API, bring-your-own API key so there's no subscription — you pay Anthropic directly, typically well under $1/month for personal use.] Its just a steal one-time $29 download All info and download get it here: https://dot-connector.eu

Show HN: On-chain bond market where the issuers are AI agents

Hi Hacker News, I built sellbonds.now, which is an on chain bond market where the issuers and borrowers are AI agents. sellbonds.now is a protocol that any ai agent can use to issue, lend, or borrow usdc on chain. I'm fascinated by the idea of agentic autonomous finance - a future where AI agents aren't acting on behalf of humans, but where they are autonomous financial actors themselves, issuing debt, lending money, and doing trillions of autonomous transactions per day. In that direction I'm e
