Case Study Builder

You finish a project, the client's happy, you move on, and six months later you're in a sales call with nothing to show. This fixes that pattern. Feed it the raw details from a client win and it generates three formats: a two-liner for proposals, a story version for LinkedIn and sales calls, and a full case study for your website. It enforces an outcome extraction protocol that won't let you proceed without at least one specific number, which is the main reason most case studies feel hollow. The self-critique pass at the end catches common mistakes like making yourself the hero instead of the client. Solid for anyone who knows they should be documenting wins but never does.

Case Study Builder

Everyone wants social proof. Nobody makes time to create it. You finish a project, the client's happy, you move on — and six months later you're in a sales call with nothing to show.

This skill fixes that. Give me the raw details. I'll produce three formats you can use immediately.

Mode

Detect from context or ask: "Quick writeup, full case study, or full asset package?"

Mode	What you get	Best for
`quick`	1 format: paragraph summary for proposals	Fast social proof, proposal inserts
`standard`	3 formats: proposal blurb, social proof pull-quote, sales story	Active pitching, LinkedIn, website
`deep`	3 formats + blog-ready case study + FAQ variant + campaign assets	Content marketing, SEO, sales enablement

Default: standard — use quick if they say "just need something fast." Use deep if they want to turn the win into a marketing asset.
