ultrasearch

Recap everything the web says about a topic — keyless multi-backend web search into a citation-checked, tiered Markdown + HTML report, in five modes (topic/bug/research/learn/startup), plus an agentic deep-research tier (decompose, merge, adversarially verify). The web-facing sibling of ultradoc. A skills.sh agent skill.
