Porter Competitive Strategy Skills

Turn competitive strategy from abstract theory into structured analysis.

12 executable skills + 1 orchestrator extracted from Michael Porter's Competitive Strategy — the foundational text on industry analysis and competitive positioning. Every skill was sense-checked against the original book via NotebookLM. Every sub-factor, checklist, and decision tree comes from Porter's own language, not summaries or interpretations.

Ask your agent to "analyze this industry" and get a structured five forces assessment with 32 sub-factors rated. Ask "what move should we make?" and get a commitment framework with retaliation predictions. Ask "are we stuck in the middle?" and get a diagnostic checklist with organizational requirements you're missing.

Tier 1 — Entry points (no dependencies)

Skill	What it does	Porter source
/analyze-five-forces	Assess industry structure across 32 sub-factors (8 entry barriers, 8 rivalry drivers, 7 buyer power factors, 6 supplier power factors, 3 substitute indicators), identify governing forces, rate overall profit potential	Ch 1
/profile-competitor	Build a four-component competitor profile (future goals, assumptions, current strategy, capabilities), generate a response profile predicting satisfaction, likely moves, vulnerabilities, and retaliation triggers	Ch 3
/map-strategic-groups	Plot competitors across 13 strategic dimensions, select optimal axes, assess mobility barriers between groups, analyze per-group rivalry and bargaining power differences	Ch 7
/diagnose-industry-type	Classify an industry as emerging, fragmented, transitioning to maturity, or declining using Porter's 14 evolutionary processes, then route to the appropriate industry-type strategy skill	Ch 8–12
