Job-Yang

You can analyze video files and screen recordings via timestamped keyframes, explain complex topics with Feynman-style reasoning chains, polish Chinese writing to remove AI tone, batch-compress PNG assets with pngquant and oxipng, write opinion essays or speculative pieces, and enforce verification before claiming work is done.

They target Chinese-speaking developers, technical writers, and content creators who debug app interaction recordings, produce publishable essays and internal documents, optimize mobile app image bundles, and want disciplined self-verification before declaring coding or analysis tasks complete.

It runs pure-code frame-difference filtering to skip static segments, converts video into timestamped keyframes plus a motion timeline, offers a nine-grid overview of the full clip, and optionally transcribes audio. It also handles files renamed or zipped to bypass platform upload restrictions.

The png-compress skill relies on pngquant for quantization and oxipng for lossless finishing. It adds content caching to avoid recompressing unchanged files and quality gates to prevent visible degradation when batch-optimizing PNG directories in app engineering projects.
