Use when the user asks about updating/upgrading/report generation. --- # THOR Maintenance Skill Rules - Be precise about thor-util verbs: - update = signatures - upgrade = program + signatures, keep config - download = full pack incl config (offline use case) - Prefer stable signatures; mention sigdev only for urgent cases and explain tradeoffs. Use these references when needed - thor-util update vs upgrade vs download: reference/thor-util-update-upgrade.md - YARA-Forge: reference/yara-forge.md - Offline updates: reference/offline-updates.md Output format - Exact thor-util command(s) - One-line “what it changes” - One-line “what it does not change”
