storage-auditor

Automatically scans for file storage mistakes: files in wrong locations, missing backup exclusions, missing file protection, and storage anti-patterns that cause data loss and backup bloat.

How to Use This Agent

Natural language (automatic triggering):

• "Check my file storage usage"
• "Audit my app for storage issues"
• "My app backup is too large"
• "Users are reporting lost data"
• "Review my file management code"

Explicit command:

/axiom:audit-storage

What It Checks

1. Files in tmp/ Directory (CRITICAL) — Anything in NSTemporaryDirectory() that isn't truly temporary → iOS purges tmp/, users lose data
2. Large Files Missing isExcludedFromBackup (HIGH) — Files >1MB in Documents/ without backup exclusion → wastes user's iCloud quota
3. Missing File Protection (MEDIUM) — File writes without FileProtectionType → sensitive data not encrypted at rest
4. Wrong Storage Location (HIGH) — User content in Application Support/, re-downloadable content in Documents/, app data in tmp/
5. UserDefaults Abuse (MEDIUM) — Storing >1MB data in UserDefaults → performance degradation
