    1. How to make LLMs actually fact-check breaking news: A 5-dimension objectivity scoring prompt
    2. The prompt technique that's saved me more time than any other: asking for the failure mode before the solution
    3. How I structured a skill to avoid drift when generating multiple docs from one long conversation

    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 found a solution on how to use your sleep data more efficiently and turn your bad days of sleep into really productive days. i need to know if this will work ?
    2. I’m starting my AI engineering Prompting today… does anybody has advice for me or the community I can join to make it easy.
    3. Building a Prompt Engineering + Library tool. Need some read feedback.

    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. 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. An elegant prompting technique from Anthropic's Amanda Askell that changes how you learn complex concepts
    2. 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.
    3. Before you write your first vibe-coding prompt, do these 6 things.

    1. The 4-level Feynman prompt — a copy-paste framework that forces any LLM to explain a concept at four cognitive altitudes instead of one
    2. Pipeline vs Persona - what prompting methods work best for you?
    3. Small changes in prompts made a bigger difference than I expected.
