Claude Skill File Applies Negotiation Theory to Email Composition

A developer on r/ClaudeAI shared a SKILL.md file they built that applies negotiation theory to email composition. The skill specifically uses negotiation frameworks including BATNA (Best Alternative to a Negotiated Agreement), anchoring, and reciprocity.
How the Skill Works
The skill changes Claude's email generation approach in several specific ways:
- Before skill: Claude produces a single polite, generic email
- With skill: Claude first assesses the situation by analyzing stakes, leverage, power dynamics, and your fallback position
- The skill then generates 2-3 email variants optimized for different outcomes
- Each variant includes tradeoff analysis
Technical Implementation Details
The developer noted several key technical aspects:
- Claude knows about negotiation theory but doesn't apply it to email writing unless explicitly structured to do so
- The SKILL.md loads scenario-specific playbooks from reference files only when relevant
- This selective loading approach keeps token costs low
- The skill forces Claude to apply negotiation frameworks that it already understands conceptually
The developer mentioned being available to answer questions about how skill files work and how they structured this particular implementation.
