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.
