Scored across 5 tools
Each tool has a clearly distinct purpose: adding subtitles, clipping, extracting audio, merging, and transcoding. Even within add_subtitles, the two modes are explicitly described, leaving no ambiguity.
All tools follow a consistent pattern: the prefix 'ffkit_' followed by a verb (clip, merge, transcode) or verb_noun (add_subtitles, extract_audio). The naming is uniform and predictable.
Five tools cover the essential media operations (clipping, format conversion, audio extraction, subtitles, concatenation) without being overwhelming or too sparse. The count is well-scoped for an ffmpeg wrapper.
The tool set covers core media manipulation tasks, but lacks some common operations like media info, video-only extraction, or advanced filters. Minor gaps exist, but the main workflows are supported.
