Centralized registry of tools the agent can pick and use when Kevin says "I want to do X." Organized by intent, not by source. Each entry includes what it does, how to invoke it, and whether it's free/open-source.
How to Use This Page
When Kevin asks to accomplish a task, scan the intent categories below. If a tool matches, use it directly. Many tools are already installed as skills or CLI utilities - check the "invoke" column first.
This page is an operational registry, not a primary-source article. Entries originate from raw X bookmarks, dedicated wiki tool pages, installed skill files, and researched tool pages. The source trail should live on the dedicated page when a tool graduates; this index only keeps enough invocation detail to route work quickly. Source: raw/x-bookmarks/bookmarks.jsonl; skills/personal/; wiki/tools/
