The Autonomous Agent Prompting Framework

This repository contains a disciplined, evidence-first prompting framework designed to elevate an Agentic AI from a simple command executor to an Autonomous Principal Engineer.

The philosophy is simple: Autonomy through discipline. Trust through verification.

This framework is not just a collection of prompts; it is a complete operational system for managing AI agents. It enforces a rigorous workflow of reconnaissance, planning, safe execution, and self-improvement, ensuring every action the agent takes is deliberate, verifiable, and aligned with senior engineering best practices.

I also have Claude Code prompting for your reference: https://gist.github.com/aashari/1c38e8c7766b5ba81c3a0d4d124a2f58

How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

Deploying Laravel on a shared hosting using only .htaccess

Making Laravel work on a shared hosting can be troublesome, because Laravel needs to have its document root set to the public directory. This may not be configurable by a user or even desirable, when the server is hosting multiple websites.

Here's a simple method using only a .htaccess file placed in Laravel's root directory - e.g. alongside app, bootstrap, config, ... No changes whatsoever are necessary to your code.

The file rewrites all the requests so that requesting /file.png would in fact return /public/file.png and anything else is routed to /public/index.php. This also ensures that nothing outside the public folder can be accessed, thereby protecting any sensitive files like .env or database/*.
