CLAUDE.md Starter Pack

What it does

Stop writing CLAUDE.md from scratch on every project. Get 25 production-ready templates for Next.js, FastAPI, React Native, Shopify, Go, Rust, n8n, and 18 more stacks. Each one includes real conventions, anti-patterns, and architecture rules Claude Code actually uses.

Every project built with Claude Code needs a CLAUDE.md. Without one, Claude guesses your conventions and writes generic code you have to rewrite. With a good one, Claude acts like a senior developer who knows your stack.The problem: writing a great CLAUDE.md takes 2-4 hours per project. You have to figure out the right structure, what to include, what Claude actually uses. Most developers either s

  Use Claude Code to Query 600 GB Indexes over Hacker News, ArXiv, etc.Dec 2025 · exopriors.com · ▲397

  Paste in my prompt to Claude Code with an embedded API key for accessing my public readonly SQL+vector database, and you have a state-of-the-art research tool over Hacker News, arXiv, LessWrong, and dozens of other high-quality public commons sites. Claude whips up the monster SQL queries that safely run on my machine, to answer your most nuanced questions. There's also an Alerts functionality, where you can just ask Claude to submit a SQL query as an alert, and you'll be emailed when the ultra nuanced criteria is met (and the output changes). Like I want to know when somebody posts about…

  Claude.md templates based on Boris Cherny's adviceFeb 2026 · github.com · ▲10

  Boris Cherny (Claude Code creator) recently dropped a threads on how his team at Anthropic uses Claude Code. The key insight: they don't treat it as a static config. After every correction, they tell Claude "Update your CLAUDE.md so you don't make that mistake again." Claude writes a rule for itself. They review it, commit it to git. The mistake never happens again. I cross-referenced his tweets with Anthropic's official docs and other best practices for CLAUDE.md and then packaged it into a starter kit: - Fill-in-the-blank templates for Next.js/TypeScript, Python/FastAPI, and a…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
