simota/summon
Channeling the documented thinking of named notable figures (an 'itako' medium) — applies their mental models, heuristics, and decision-style to your problem as advisory lenses. Don't use for decisions/verdicts (Magi), synthetic user personas (Cast), or fixed founder-mentor coaching (Sage).

Take simota/summon from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
