Each tool has a largely distinct action: probe vs. list, transcode vs. remux, audio vs. video. The only real overlap is extract_audio versus extract_stream (which can also pull an audio stream by index), and thumbnail vs. extract_stream for frame grabbing, but the descriptions make the intended boundaries clear enough.

Nine of ten tools follow a clean snake_case verb_noun pattern (probe_media, transcode_video, extract_audio, convert_image, burn_subtitles). 'thumbnail' is the lone bare noun, a minor deviation from an otherwise predictable convention.

Ten tools is well-scoped for a media encoding server, covering inspection, listing, video/audio transcoding, remuxing, extraction, image conversion, thumbnails, and subtitles without padding. Each tool maps to a concrete operation a user would need.

The core encode/convert lifecycle is well covered, including probe, codec discovery, transcode, remux, extract, and subtitle burn-in. Minor gaps exist around trimming/cutting to a time range, concatenating files, and extracting subtitle streams, but none are dead ends for typical workflows.
