about_unfrozen

Who Gabriel Lopez is (public facts from unfreeze.us/about/), how Atlas studies are graded, how to cite the Atlas and its license, and the paid Change Check-up booking link.

Discovered
get_answer

Match a question about middle managers and change to the closest of the Atlas's fact-checked answer pages (deterministic keyword matching, no AI). Returns the answer text exactly as published, its graded sources and the page URL. If no page fits well, it says so and returns links to Ask the Atlas and the Atlas instead of guessing.

Discovered
get_study

One Atlas study record by its slug (from search_studies, e.g. "huy-2011") or its DOI: citation, design, setting, strength grade and what it means, Loop parts with verdicts, whether it is about change, Unfrozen's plain-language summary, related studies, the answer pages that cite it, and its unfreeze.us page.

Discovered
list_loop_parts

The parts of the Unfrozen Loop, a working model for leading change from the middle, each with a one-line description, how many Atlas studies inform it (supporting, mixed, challenging) and its unfreeze.us page.

Discovered
search_studies

Search the Atlas of the Middle (173 studies on middle managers and change, each with a strength grade and Unfrozen's plain-language summary). Matches words in the title, summary, setting, authors and journal. Returns each study's label, year, journal, design, grade, Loop parts, one-line summary and its unfreeze.us page. Filter by Loop part or grade.
