• LASTFM_API_SECRET: Required to sign write operations (love/unlove, scrobble)

Workflow

Guardrails

• Never log or expose API keys or session keys in output
• Rate limit: respect Last.fm's 5 requests/second limit
• Write operations must fail gracefully if LASTFM_SESSION_KEY not set
• All user inputs must be URL-encoded before API calls
• Only connect to ws.audioscrobbler.com - no external endpoints
• Handle missing data gracefully (e.g., no now playing, empty loved tracks)
• Validate period parameter is one of: 7day, 1month, 3month, 6month, 12month, overall
• Validate recent limit is numeric and within 1–200

Error Handling

Error Code	Meaning	Action
10	Invalid API key	Tell user to check LASTFM_API_KEY
6	Invalid parameters	Check required params are present
29	Rate limit exceeded	Wait and retry, inform user
26	Suspended API key	Direct user to Last.fm support
