Commands

Command	What it does
/consult <problem>	Full consulting engagement: clarify → hypothesis → issue tree → analysis → pyramid-structured recommendation
/analyze <company or market>	Layered strategic analysis: PESTEL → Porter's 5 Forces → SWOT/3C → "so what" implications
/case-practice [type]	Mock case interview (McKinsey/BCG/Bain style) with exhibits, math, and a scored debrief

Usage

Try asking:

• /consult our SaaS churn doubled last quarter — what should we do?
• /analyze the Japanese convenience store industry
• /case-practice profitability
• "Size the market for EV charging stations in Germany"
• "Help me structure this recommendation for my exec presentation"

The skill also activates automatically when you:

• Analyze business problems
• Develop strategy
• Structure presentations
• Evaluate M&A opportunities
• Size markets
• Improve profitability
• Manage projects
• Drive organizational change

How it works

Everything is a markdown skill — no runtime code.

• skills/consulting/SKILL.md is the entry point: its frontmatter description tells Claude when to activate, and the body sets behavior (hypothesis-first, pick 1–3 frameworks, end with "so what?") plus a selection guide mapping question types to frameworks.
• The frameworks live in seven category files (strategy.md, cases.md, finance.md, …) that Claude reads on demand, so the full ~3,400 lines of framework content never sit in context at once.
• commands/ defines the three slash commands as prompt templates over the same skill.
• skills/consulting/templates/ holds five fill-in deliverables (SWOT report, business case, project charter, RACI, Business Model Canvas) the skill offers to complete.
• CI (validate.yml) validates the plugin manifests, keeps the two version fields in sync, and checks every relative markdown link.
