eightytwenty gives your assistant the method strong case-competition teams use to build decks. It asks the right questions
first, writes the storyline and a plan for every slide, waits for your approval, then builds and checks the deck. While it
plans, it searches a library of more than 900 slide layouts and 39 whole-deck flows taken from strong case-competition
and investment-banking decks, so each slide starts from a layout that has already worked.
The library holds no original slides. Every entry is an abstract wireframe with its layout, why it works and when to use it.
Your assistant rebuilds the idea in your own style.

## Tools
| Tool | What it does |
| get_playbook | The method: workflow and intake questions, storyline and impact slides, slide types, taglines, writing conventions, design options, QA and the completion audit |
| find_references | Search slide layouts by what the slide needs to do, filtered by slide type, industry, data type, impact kind or deck style |
| find_deck_flows | Search whole-deck flows: section order, pacing and arc, by industry, length or style |
| get_reference | One result in full: its layout record, component layout and wireframe, or one deck flow |
| find_images | A logo, icon or photo for a slide: public-domain logos, permissive icons and openly licensed photos, with a credit line only when the licence needs one |
Every tool is read-only. Nothing can list, export or upload to the library.
