    1. Any multi-step "prompt builder" tools for AI Agents, of sorts? Is this idea even worth investigating?
    2. I built a free tool to write, test, and compare prompts side-by-side — no more guessing why your prompt sucks
    3. What are the best free or low monthly cost for ai image manipulation and short video usage?

    1. I built a free skill that takes you from "I have an app idea" to a real plan and solid MVP
    2. I got tired of copy-pasting prompts and losing track of versions, so I spent the last few months building a local, open-source Prompt IDE. No cloud, 100% free.

    1. I’m starting my AI engineering Prompting today… does anybody has advice for me or the community I can join to make it easy.
    2. What's the first thing you'd show a complete beginner before they write a single line of an agent prompt?

    1. Two rather important prompts that won't easily be recognised by regular chatGPT because they describe things we, humans, always had, but never used to talk about, and so are not in LLM training data, despite being obvious.
    2. The most effective prompt constraint I've found for ideation: Cross-Disciplinary Mapping
    3. Summaries are dead. The attention economy rewards cognitive conflict. Use this prompt pattern to extract it.

    1. AI answered a question in 4 seconds that i spent 6 years of therapy trying to answer. i don't know how to feel about that.
    2. Before you write your first vibe-coding prompt, do these 6 things.
    3. One prompt structure that works for art, tech and creative work every time
