Mixing was the one audio surface no skill covered: the effect chain, automation lanes and the voiceover carve existed with no guidance, so an agent had the attributes and none of the judgement for using them. The skill teaches the carve as what it is — a relationship between two tracks, wired like a sidechain, with the settings on the bed naming the voice — and routes the effect families by the problem each solves rather than listing parameters. It ships scripts/carve.mjs because a skill teaching a feature agents cannot operate is not much of a skill: the analysis needs decoded PCM, and the only other way in is clicking a Studio panel. Same core functions and same decode rate, so headless output and panel output are the same three attributes. It finds the voice and the bed itself — names first, then by ear, measuring how much of each track is quiet, since a voice stops between phrases and a bed does not — and refuses rather than guessing when two tracks are too close to call. References carry the full registry with which parameters can actually be automated (the four worklet effects expose none, so a lane on one is silently inert) and the exact JSON of the three attributes. Counts, catalogues and the core-skill manifest updated in lockstep; the pinning test in skillsManifest is what caught the two surfaces the maintenance checklist in CLAUDE.md does not name.
