Problem, work, result. Under 400 words.
A portfolio case study built from a finished client project, structured around the client's problem and the decisions that mattered.
A portfolio of images tells a buyer you can make things. It does not tell them you can solve their problem. The case studies that do exist tend to narrate the process in order, which is the part the buyer cares about least.
Portfolio Case Study opens on the client's situation, picks the two or three decisions that shaped the outcome, and states the result using only what you can support. It adds one honest line on what you would do differently, and it checks permission before anything goes public.
What it produces.
- →A case study in problem, decisions, work, result order

Before you buy.
How is this different from just asking Claude directly?
Asked cold, Claude writes a flattering narrative and tends to fill gaps with plausible outcomes. This Playbook uses only the facts you provide, leaves out anything you cannot support, and structures the page around the decisions, not the timeline.
How is this different from a Tool?
Playbooks are systematically produced to a fixed template and priced accordingly ($12.99). Tools are hand-built, one at a time, and go deeper ($39 to $199). A Playbook gives you a reliable method for routine work; a Tool is for when the judgment matters more than the format.
Will this work with ChatGPT, Gemini, and other LLMs?
Yes. You get a native Claude Skill (.zip) that auto-invokes in Claude, plus a plain .md you can paste into a ChatGPT Custom GPT, a Gemini system prompt, or any LLM. The procedure travels with the file.
Can I share this with my team?
It's licensed for your own personal and professional use. The output it produces is yours to circulate. To put the Playbook itself in the hands of a whole team, email hello@authority.md about team licensing.
What if it doesn't work for me?
