Pick it when the CLI consumer is a machine: every command is non-interactive and JSON-emitting, so your agent or CI pipeline can inventory, install, and dedupe skills without a human — that plus `asm audit` (finds duplicate/stale skills scattered across 19 providers' hidden dirs) is the differentiator. NOT the breadth play: ~4.3K curated skills vs skillkit's 400K firehose, and no format translation between agent dialects. Solo-maintainer project — fine for personal/team tooling, but if you need org-level reproducibility and governance, apm's manifest+policy model is the grown-up answer.
