What is HackTheSim?

HackTheSim is your no-nonsense prompt library. Every template is built with our CORE recipe so you can reuse it in real work without hand-holding.

  • Context – the facts and inputs the model needs
  • Outcome – the single, measurable goal
  • Rules – tone, format, constraints, length
  • Examples – patterns the model can mirror

New framework: HFML

🏳️ Flag in the sand · Built in public

HFML = Human-First Mechanism Leadership

A leadership framework that treats mechanisms as guard rails for action, while protecting the human part of work: clarity, autonomy, psychological safety, and creativity.

  • Mechanisms reduce noise (repeatable processes, decision loops, templates)
  • Human-first keeps dignity, trust, and judgement where it belongs
  • AI-as-middle-layer turns intent into action without endless back-and-forth

HFML lives on LeadershipPlaybooks.com as the canonical reference for citations and search indexing.

Why this exists

Most leadership models are either vibe-heavy or process-heavy. HFML is the bridge: procedural guard rails with humanity baked in.

If you care about shipping without burning people out, this is your lane.

        Sales Email Rewrite for Cold Outreach

        📋 Instruction:

        Rewrite the sales email below to make it more engaging, personalised and focused on value. Limit to 90 words. Use a friendly, confident tone. Include a clear benefit and a call to action. Audience: Small business owners in retail using spreadsheets for inventory. Product: StockFlow (cloud inventory management SaaS).

        📨 Original Email:

        Hi, I'm reaching out to see if you're interested in trying our inventory software. It can help you track products and save time. Let me know if you want to try a demo.

        🎯 Full Prompt:

        Rewrite this email to small retail business owners still using spreadsheets for stock management.
Product: StockFlow (cloud based inventory SaaS).
Make it conversational, highlight a specific pain point, include a clear benefit and end with a low pressure call to action for a demo. Keep it under 90 words. Include a subject line.

        ✅ Example Output:

        Subject: Tired of Spreadsheet Stock Chaos?
Hi [Name],
Managing inventory in spreadsheets is frustrating - errors, missed reorders and wasted hours are all too common. StockFlow is built for retailers like you: track products, automate reorders and get real-time updates - all in one place.

Want to see how it could save you hours each week? Let's book a quick, no-pressure demo.

- Sam from StockFlow

        Why it works:
        › Speaks directly to a pain point (spreadsheet frustration).
        › Highlights a core benefit and specific automation.
        › Uses a clear, non-pushy call to action and a credible sender.
