Summary
Exposes 11 strategy frameworks as structured markdown prompts that guide LLMs through proven consulting methods like Wardley mapping, VRIO analysis, and pre-mortems. Each skill runs in diagnostic, review, or alert trigger mode and reads/writes to a shared company-context.md file that accumulates strategic intelligence across sessions. The strategy-diagnostic skill acts as an entry point that detects which frameworks to apply based on your situation. Built for any MCP client and works across Claude, ChatGPT, Gemini, or local models. Reach for this when you need AI-guided strategic thinking sessions that produce actionable output rather than generic advice. Based on 20 years of consulting practice and distributed under CC BY 4.0.

Eterdis Strategy Skills
Open strategy frameworks designed to run as AI-guided conversations. Each skill is a single markdown file that turns any large language model into a strategy thinking partner.
Built on 20 years of consulting practice. Free, open, model-agnostic.
What these are
Strategy skills are structured prompts in SKILL.md format that guide an LLM through a proven strategic framework — asking the right questions, spotting patterns, surfacing contradictions, and producing actionable output. They work with Claude, ChatGPT, Gemini, or any model that reads markdown.
Every skill runs in three modes:
- Diagnostic — deep first-use session (30-60 minutes)
- Review — periodic re-assessment (15-20 minutes)
- Alert Triggers — early-warning tripwires to monitor between sessions
All skills read and update a shared company-context.md file that accumulates strategic intelligence across sessions.
