What's inside
The instructions your model reads when the skill loads.
Apply Porter's Five Forces framework to assess industry competitive dynamics and attractiveness. Use this skill when the user needs to analyze an industry's profitability structure, evaluate market entry barriers, assess supplier or buyer bargaining power, or understand competitive intensity — even if they say 'industry analysis' or 'is this market worth entering' without naming Porter's explicitly.
