Ralph Build. Auto Guarded Python Harness

What it does

Ralph Harness is a small Python package for running Claude Code, Codex CLI, Gemini CLI, Cursor, and other coding agents in guarded local loops. Specs, fresh context, hard caps, git hooks, CI verification, and coverage gates. No hosted backend, no token service, no agent lock-in. A lightweight spec-driven loop harness for Claude Code, Codex, and Gemini CLI. Fresh-context runs, specs, commits, and gates to get you and your agents productive immediately. - rxdt/py_ralph_frame

A repo-native coding-agent loop harness for Claude, Codex, Copilot, and other CLI agents. Agents can edit. Gates decide what lands. You set the plan in motion. The agents take a prompt, and each iteration must update specs and commit through guardrails. - rxdt/loopgate_harness

  For the last year we've been building an AI mobile app builder. Last week we decided to generalize our agent harness and benchmark it against vanilla Claude Code. Turns out the tools we built for app building were significantly more efficient than the native Claude Code tools. When we ran benchmarks we beat Claude code on speed (~40% faster) , cost (25-55% cheaper) and performance (+17% on Terminal Bench 2.0). Today we're making our agent harness publicly available as a Claude Code plugin. Use code WOZCODE1 to try it for $1 at wozcode.com

  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!
