Apply SEO frontmatter (description, image, permalink, redirect_from, alt text) to a Jekyll _posts/*.md file so individual posts rank well on Google. Use this whenever the user creates a new post in `_posts/` and asks for SEO, "검색 잘되게", "frontmatter 채워줘", or otherwise wants the same treatment that was applied site-wide on 2026-05-07.
Compress a finished lecture PDF with ghostscript, drop it into slam_slides/, and add a new Lecture NN entry to slam.md. Use this whenever the user says they "finished" or "completed" a new SLAM lecture, asks to "add Lec NN" / "Lecture NN을 추가", supplies a path to LecNN_SLAM_for_everyone.pdf, or otherwise wants to publish the next lecture on the /slam/ page. This is the canonical end-to-end "publish a new lecture" workflow for this repo — prefer it over running the gs command and editing slam.md by hand.
Fill in (or refresh) a lecture entry under /slam/ in slam.md. Each lecture's sub-items are derived from the top-bar section markers of its Beamer-style slide deck. Use when a new Lec NN deck is finalized or when existing placeholders need to be replaced with real sub-topics.
Resize and compress publication thumbnail images and videos (PNG, JPG, GIF, MP4) under `img/publications/` so the publications page stays fast on mobile. Use whenever the user adds new thumbnails, mentions oversized media on the site, asks to audit `img/publications/`, or wants to shrink a GIF/MP4 anywhere in the LimHyungTae.github.io repo — even if they don't say the word "compress" (e.g. "this gif is huge", "make this png smaller for the site", "thumbnail is 5MB").
