Emojilist

Security checks for vulnerabilities and agentic risk

Overview

This is a local emoji lookup utility, and the only confirmed mismatch is that it advertises copying but only prints emojis for manual copying.

Use this as a terminal emoji reference tool. Expect it to print emojis and names so you can copy them manually; do not expect automatic clipboard copying or emoji shortcode output.

Finding

The code substantially matches an emoji lookup/reference utility: it searches by keyword, lists category contents, and browses categories from a built-in emoji database. However, the declared description explicitly says users can 'copy them for instant use' and 'copy codes,' but the script never interfaces with the clipboard, outputs shortcode aliases, or performs any copy action—it only prints emoji/name/category text to stdout. Additionally, the script includes extra user-facing capabilities (random selection, popular emoji listing, and listing categories) not mentioned in the description. The main material mismatch is the missing copy capability.
