What it does

Coding agents are getting smarter. Their prompts aren't. Gemini CLI sends 4,096 tokens before you type a word. Zap sends only what the current task needs — Java skill for Java, React skill for React. A greeting costs 31 tokens, not 2,000. AST code index means it never writes files that already exist. Single Rust binary, no runtime, bring your own API key. Open source. Benchmarked.

ZAP is a terminal-first, local AI coding agent built in Rust. It uses AST-powered codebase indexing and lazy-loaded skills to completely eliminate prompt bloat and minimize context token costs. - zap-coding-agent/zap-coding-agent

  Agent 37Mar 2026 · agent37.com · ▲401

  Hey HN, I noticed there are 1,000+ MCP skills on GitHub with zero way for creators to charge for them. So I built Agent37. Selling Claude skills today means asking customers to download your skill, set up Claude Code on their laptops, configure MCP servers, and pray it works. No trial, no updates, often you're just handing over the source. Agent37 lets creators upload a skill, share a link, and anyone can try it instantly (no Claude account needed). Built-in Stripe, creators keep 80%. Looking for feedback on the approach. Would you use something like this?

  Gemini web client in 100 lines of C2023 · github.com · ▲91

  Gemini protocol documentation claims that it is possible to write basic web client in 100 lines of code proving protocol simplicity. Easy in modern scripting language but can it be done in ANSI C? Let the source code decide. Someone suggested to share this silly project of mine with HN community so here it is. Enjoy

  Zap Code – AI code generator that teaches kids real HTML/CSS/JSMar 2026 · zapcode.dev · ▲12

  Zap Code generates working HTML/CSS/JS from plain English descriptions, designed for kids ages 8-16. The core loop: kid types "make a space shooter game", AI generates the code, live preview renders it immediately. Three interaction modes - visual-only tweaks, read-only code view with annotations, and full code editing with AI autocomplete. Technical details: Next.js frontend, Node.js backend, Monaco editor simplified for younger users, sandboxed iframe for preview execution (no external API calls from generated code). Progressive complexity engine uses a skill model to decide when…

  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!

  Performative-UI – A react component library of design tropes▲1,181

  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!
