Summary

Reconstructs a book into x → f → f(x): the problem it addresses, the author's central answer, and how that answer changes your judgment or action. You give it a book title, PDF, or excerpt (or just ask 拆书), and it generates an org-mode note with three summary lines up top, then expands the logical chain in four fixed sections. It scans for the hardest concept to visualize and picks the lowest-cost representation, whether that's an ASCII diagram, a table, or just prose. Not for chapter summaries or framework audits. The completion checklist is rigorous: it verifies the three lines actually connect as a chain, that f explains mechanism rather than listing terms, and that f(x) specifies what concretely shifts in understanding or action.

experience-content-media-search

forcedotcom/sf-skills

Searches for and retrieves existing visual media (images, logos, icons, photos, graphics, banners, thumbnails, hero images, backgrounds) from sources such as Salesforce CMS, Data 360 or any other source. Use this skill ANY TIME a user request involves finding, searching, getting, fetching, retrieving, grab, looking up, locating media. NEVER call search_media_cms_channels, search_electronic_media tools directly — always go through this skill first. This skill must be activated before any tool is used for media search or retrieval, without exception. Takes PRIORITY and activates FIRST when ANY media search/retrieval is mentioned, regardless of what else happens with the media afterward. Triggers for requests like "search for logo", "find hero image", "get company logo", "locate icons", "fetch background image", "retrieve product photos". Handles the search and source selection workflow. Does not apply when the request is about brand search, to generate NEW images with AI, or edit existin
