# Using the Character & Item Library Libi maintains a cross-piece **objects catalog** — "objects" here means both **characters** (people, figures, fictional or real) and **items** (objects, products, props). This is a general capability across every video type (UGC ads, music videos, narrative shorts, tutorials, anything) — it is not specific to product/UGC work. Characters and items have the same shape and the same set of MCP tools, just for different kinds of subjects. You should be **proactive** in both directions: auto-catalog central recurring subjects as you find them during analysis (report inline, don't gate on asking first), and proactively surface existing catalog entries when they're relevant to what the user is doing — don't wait for the user to ask "do we have a Jessica already?" ## Core principles 1. **Central recurring subjects get auto-cataloged; ambiguous cases get asked.** Auto-create when a subject is clearly the recurring focus of the content (the presenter, the product being advertised, a named character who reappears). Ask first only when it's genuinely unclear whether the user wants this subject saved (e.g. a subject who appears once and might be a one-off). 2. **Never catalog background noise.** One-off extras, generic objects, and strangers in a busy frame stay out of the catalog regardless of how confident you are — this is a quality and privacy guard, not a judgment call to relax. 3. **Names are unique within each catalog.** Two characters can't
