description	Turns a real customer result into a structured case study — situation, sticking point, intervention, numbers, quotes — plus a short social version cut from the same material. Use when a genuine result exists and needs to work as proof across the funnel.

Case Study Writer — proof, structured

A case study is not a testimonial with padding. It is the story of a decision the reader is about to make, told by someone one step ahead of them. The structure does the selling: a before-state the reader recognises as their own, a mechanism they can believe, and numbers they could check.

Inputs

• The customer result and all raw material — notes, metrics, quotes, timeline: $ARGUMENTS
• From marketing-brief.md if present: the ICP (so the story is framed for the right reader), the language bank, positioning & message, the banned-phrases list, and any rules on naming customers publicly.

Do this

1. Inventory the raw material: who the customer is (and what may be named publicly), the before-state, what was actually done, the numbers with their timeframe, and verbatim quotes. List what is missing and ask once — none of it gets invented.
2. Pressure-test the numbers. Baseline, timeframe, and what else was happening that could explain the change. A number without a baseline is a claim, not proof — present it honestly or leave it out.
3. Write the case study in this shape:
   • Title — result-led and specific, no hype adjectives.
   • The situation — the before-state in the customer's words; the target reader should say "that's me" by line three.
   • The sticking point — what they had already tried and why it failed.
   • The intervention — what was done, step by step. The mechanism is the persuasive part; show the work.
   • The numbers — baseline to result, timeframe, context.
   • In their words — real quotes only, lightly trimmed, never improved.
   • What this means for you — the bridge to the reader, one CTA.
4. Cut the social version: hook, three-beat arc, one number, CTA — reshaped for the feed, not compressed from the long copy.
5. Run the naming pass. Apply the brief's rules on naming customers: keep the numbers, drop names where required, and note anything that needs the customer's sign-off before publishing.

Output

The full case study, the social version, and a proof-integrity note: the source of every number and quote, plus what to confirm with the customer before it ships.

Rules

• Every number and quote traces to a real source. Nothing composite, nothing illustrative — if it is not real, there is nothing to write.
• Curiosity belongs in the title, never in the numbers.
• The intervention sells the method, not the vendor. Readers trust work they can see.
• Keep the customer the hero. The company is the guide who turned up with a map.
