lex-cost-scanner

Cloud cost optimization scanner for LegionIO. Scans AWS/Azure accounts for idle and oversized resources, classifies findings via LLM (with rule-based fallback), deduplicates across scans, and delivers a weekly Slack Block Kit report.

• WeeklyScan actor — interval actor fires scan_all every 604,800 seconds (1 week)
• Scanner runner — iterates configured accounts, fetches resources, classifies each one
• Classifier helper — uses legion-llm if available; falls back to CPU utilization rules
• FindingsStore — thread-safe in-memory store with dedup by account_id:resource_id:finding_type
• Reporter runner — generates Slack Block Kit weekly summary and posts via lex-slack
