sammcj/agentic-coding ? reverse-engineered prompt

Build me a clean, easy to use repo for agentic coding rules, prompts, skills, and examples that I can reuse across tools like Claude Code, Cursor, and other coding agents.

I want the content organized so the most useful rules and templates are easy to find, with separate places for general agent rules, reusable skills, prompt templates, and any Claude specific extras. Please make it practical and well written, focused on helping an AI coding assistant plan work, stay on task, debug systematically, and keep context under control.

Include a simple guide that explains how to use the rules and when to turn things on or off, plus a few examples of good prompts and workflows. Keep it portable where possible, but it’s fine if some parts are specific to Claude Code. If anything depends on current docs or best practices, look them up online first.
