Your category 7 combined two different types: directories for finding and installing skills, and application packs tailored to a specific profession. For a more accurate comparison, this category has been split into 7A and 7B. The safest approach with directories is to separate discovery from installation: first find candidates in a directory, then review the source SKILL.md and scripts, and install the individual skill pinned to a version tag or commit. The “official marketplace” label is not a guarantee of safety; even Anthropic, GitHub, and VoltAgent explicitly say they don’t fully vet community contributions [14]. The shared format underlying all these directories is the open Agent Skills standard [15].
