Copy processed MP3s and WAVs to NAS storage. Use after Apple Music import or when re-archiving corrected files.
Move processed ZIPs to archive and clean up extraction folders. Use after album processing is complete.
Copy finished MP3s into Apple Music via the auto-import folder and verify the album lands correctly. Use once metadata is finalized and the user wants tracks added to their library — e.g. "add this to Apple Music" or "import these tracks" — even if they don't say "auto-import" explicitly. Also use to diagnose a bad import, e.g. "it showed up as separate tracks instead of one album."
Inspect and update MP3 tags: genre, artist, album, track count, compilation flag. Use when checking or fixing music file metadata — including diagnostic questions like "why do these show up as separate tracks" or "is this folder's metadata consistent," not just explicit tag-editing requests.
End-to-end processing of downloaded music purchases: extract ZIPs, verify metadata, import to Apple Music, archive to NAS, clean up. Use when processing new music downloads.
Reclaim local disk by offloading cloud-backed Apple Music downloads. Audit iCloud status, build an offload playlist that protects your DJ crates and lossless files, then Remove Download. Use when the Mac is low on disk.

| description | Validate, diagnose, and understand Agent Skills (SKILL.md) across Claude Code, Cursor, and Codex — spec compliance, vendor-specific loading behavior, and known quirks. |
Use this skill when working with SKILL.md files — validating format, diagnosing why a skill isn't loading or appearing in the catalog, or understanding vendor-specific behavior differences.
Before validating any skill, validate this one first:
Check that skill-artifact/SKILL.md itself has no metadata, compatibility, or license fields (the Claude Code demotion bug applies to any skill, including this one), and that its description is under 130 chars. If this skill is broken, its validation output cannot be trusted.
Spec validation checklist:
name: required, lowercase a-z 0-9 hyphens only, must match directory namedescription: required, 1–1024 chars, used for catalog discovery — keep under 130 chars for large skill collectionscompatibility, license, metadata fields exist in spec but trigger a loading bug in Claude Code — see vendor-claude referenceDirectory layout (agentskills.io):
