About

claude-evp

> Replace a $10K-15K positioning sprint with the Schwartz-tier EVP > framework, as a Claude Code skill pack.

Generates Early Value Propositions — the 22-word line that says "For in , we ship without ." Uses the Eugene Schwartz 5-tier awareness model so you get a different line for each tier of your audience.

Based on the JMC EVP course. No LLM calls inside the skill. Deterministic scoring catches abstract verbs, missing metrics, and tier-mismatched lines.

Adaptive kickoff. First run → routes to evp-onboarding. Once configured:

> Write a Tier 3 EVP for my ICP

Returns 3 variants (outcome-led, tradeoff-led, ICP-led), all ≤22 words, all using the operator's outcomes-will-claim list, all using PSP vocabulary, all tier-fit-verified.

Cost arbitrage

| Role | $ range | What you'd outsource | |---|---|---| | Positioning sprint | $10K-15K | One ICP segment, 1-2 weeks | | Messaging architect | $5K-12K | Hero copy + pricing page lines | | Brand strategy consultant | $25K+ | Multi-segment positioning system |

This skill pack does the structural work — generates variants by tier, validates per axis, surfaces the brief. It does NOT replace TALKING to real buyers about their language (that's the PSP layer). It DOES replace the structural drafting work.
