manage-metadata

Setup

1. Check environment variables: MEDIA_MGMT_DOWNLOADS, MEDIA_MGMT_LIBRARY_STORAGE
2. If unset, use default paths from CLAUDE.md
3. If CLAUDE.md has no paths, read config.json from the project root

Scripts are in scripts/ relative to this skill directory.

Modes

Parse $ARGUMENTS to determine mode and parameters:

• inspect (or no mode specified): Read-only metadata inspection
• update: Inspect first, then update based on user choices

Argument format

inspect <folder>
update <folder> [genre=<genre>] [clear-album-artist | set-album-artist=<name>] [set-compilation] [update-track-count]

When update arguments include pre-confirmed values (e.g. genre=Electronic), apply them directly — do not re-ask the user for values already specified in the arguments.

Inspect Mode

Step 1: Run inspection

bash scripts/inspect-metadata.sh "$FOLDER"

Step 2: Present results

Display metadata as a readable table:

#	File	Title	Artist	Album	Genre	Track	Album Artist

Step 3: Flag issues

Check for:

• Missing titles
• Missing or empty genre
• Inconsistent artist names across tracks
• Missing track numbers or wrong totals
• Album Artist set when it shouldn't be (single artist)
• Compilation flag inconsistencies

Update Mode

Step 1: Inspect first

Always run inspect before updating. Present findings.

Step 2: Ask what to update

Present the issues found and ask user to confirm what to fix. Never auto-apply changes.

Step 3: Extract genres (if needed)

If genre needs setting:

bash scripts/extract-apple-music-genres.sh

Present the genre list as numbered options. Ask user to select or type a custom genre.

Step 4: Apply updates

Run the appropriate scripts based on user's choices:

Track count:

bash scripts/update-track-count.sh "$FOLDER"

Genre:

bash scripts/update-genre.sh "$FOLDER" "$GENRE"

Album Artist (clear for single artist):

bash scripts/clear-album-artist.sh "$FOLDER"

Album Artist (set for collaboration):

bash scripts/set-album-artist.sh "$FOLDER" "$ARTIST"

Compilation:

bash scripts/set-compilation.sh "$FOLDER" true

Step 5: Verify

Run inspect again to confirm changes took effect:

bash scripts/inspect-metadata.sh "$FOLDER"

Present the updated table and confirm everything looks correct.
