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.
