GitHub Repo Collects Hidden System Prompts from ChatGPT, Claude, Gemini and More

·37 views

A GitHub repository called asgeirtj/system_prompts_leaks has compiled leaked system prompts from major AI products including ChatGPT, Claude, Gemini, Grok, and GitHub Copilot. These hidden instructions, invisible to end users, are sent to AI models before any conversation begins and govern tone, formatting, tool use, and content restrictions. The prompts were obtained primarily through extraction techniques that prompt the model to repeat its own pre-loaded instructions. The repository organises files by company in Markdown format and is licensed under CC0-1.0, making it freely usable. It has drawn wider attention, with both a Washington Post interactive feature and a CEPS data dashboard reportedly drawing on its contents.

Developer Shows How to Turn a Web App Into an iPhone App Using Floot and TestFlight

A developer building a holiday gift finder app used the Floot platform to create a web app that uses an LLM and trend data to suggest gifts. The app was then expanded with location, camera, and notification features. The developer explains how the web app was converted into a native iPhone app that carried over those features. The tutorial also covers using Floot's App Store Connect integration to upload the app to TestFlight for beta testing. The guide provides a full prompt for recreating the gift finder app.

Developer builds NewsNinja RSS reader to show each news story only once

After repeatedly seeing the same story echoed across many outlets on his morning commute, a developer built NewsNinja, an RSS reader designed to group duplicate coverage. Version 1.0 was built in roughly ten days and reached the App Store on June 21, 2024, supporting iPhone, iPad, and Vision Pro. Its core features included grouping articles about the same event, opening pieces in reader mode, and AI-generated summaries as the sole paid feature. The developer first tried AI models to group headlines but found them slow and unreliable, so switched to fast string similarity algorithms that run on-device. The app then shipped frequent small updates, adding languages and features like OPML import in the months after launch.

Staged retrieval and safe deletes for keeping engineering docs search fresh

A technical guide argues that retrieval over internal engineering documentation should use staged queries, explicit collections, and traceable source context. It recommends treating document deletion as a versioned state transition, using tombstones and revision checks so stale or deleted content is not served. The article describes bounded read paths with timeouts, capped candidates, and exponential backoff on rate limits, plus idempotent consumers for at-least-once event delivery. It also frames freshness as a policy, with re-indexing on publish and periodic reconciliation against the source of truth. The piece mentions a commercial API option for vector search but centers its advice on the retrieval contract and includes a minimal Go example.
