Skills

Hand-crafted skills for agents, built from workflows I kept manually repeating.

Skill	What it does
multilingual-caption-video	Transcribe and translate local or URL videos, burn adaptive multilingual captions, verify the result, and deliver the finished MP4 locally.
manipulating-video	Manipulate video files with ffmpeg — speed up/slow down, resize, compress, convert formats, extract audio, convert to GIF, trim, merge, and more.
upload-image	Uploads images to imgbb — local files, URLs, SVGs, base64, whatever. No more manual hosting.
terminal-recording	Record, upload, and GIF-convert terminal sessions with asciinema and agg.
ghostty-remote-control	kitty-inspired kitten remote control for agents to control ghostty terminal sessions, tabs, and windows.
github-to-markdown	Uses 2md to convert a GitHub repo, directory, or file into a single markdown document for LLM or documentation workflows.

multilingual-caption-video scales caption size with the video, selects an installed font that supports the target language, and adapts text and background contrast to the subtitle region.

Note

Skills are reusable capabilities for AI agents. They provide procedural knowledge that helps agents accomplish specific tasks more effectively. Skills can include code generation patterns, domain expertise, tool integrations, and more. _skills.sh
