square-post
Use when the user wants to publish new content to Binance Square — short text, multi-image posts (up to 4), long-form articles with an optional cover, or videos with an auto-generated cover frame. Trigger on direct phrasings like "post to Square", "publish to Binance Square", "发广场", "发布到广场", and on near-miss intents where the user clearly wants to share or publish content on Square even without naming the skill: "share this analysis on Square", "把这篇文章发出去", "发个动态", "把这个视频上传到广场", "publish my chart to Square as an article". Also use when the user provides media (images, video) plus a caption and asks to push it to Square, or asks to turn a draft into a Square article. Do not use for reading, searching, commenting, liking, editing, deleting, scheduling, or managing existing Square posts — this skill only creates new posts.

What this skill does
Square Post Skill Purpose Publish new content to Binance Square by running the local scripts in scripts/. Supported post types: Text-only short posts Image posts with up to 4 images Long articles with a title and optional cover image Video posts with an auto-generated cover image Do not hand-code API requests for normal posting. The scripts own upload, polling, cover generation, and publish behavior. Runtime Dependencies Node.js 18 or newer. The scripts use native ES modules and the built-in fetch API. ffmpeg is required for video posts because post-video.mjs extracts the first frame as the cover image. ffprobe is required when a video duration is not provided by the user. Network access is required for Binance Square OpenAPI requests and presigned media uploads. Authentication Posting requires a Binance Square OpenAPI key. Before posting: Prefer BINANCESQUAREOPENAPIKEY from the user's environment if present. If it is not present, the scripts automatically check ~/.config/binance-square/openapi-key. If no valid key is found, ask the user to provide an API key first. If the user wants to reuse the key in future requests, save it with BINANCESQUAREOPENAPIKEY=<apiKey> node scripts/save-key.mjs; otherwise use it only for the current command environment. Tell the user they can create an API key at: https://www.binance.com/square/creator-center/home Pass the key only via BINANCESQUAREOPENAPIKEY (env or saved file). Never write it into command arguments or print the full key — CLI args appear in ps output and shell history. When mentioning a key, show only the first 5 and last 4 characters, such as abc12...xyz9. Scripts All commands should be run from this skill directory. Text Or Article Post Use for text-only short posts or long articles without images. Long article with title and no cover: Flags: --text required, post text content --title optional, sets article-style content Image Post Use for short image posts or long articles with a cover image. …
