+# AI skill levels:
+#     0:     Wild Pokémon
+#     1-31:  Basic trainer (young/inexperienced)
+#     32-47: Medium skill
+#     48-99: High skill
+#     100+:  Best skill (Gym Leaders, Elite Four, Champion)
+# NOTE: A trainer's skill value can range from 0-255, but by default only four
+#       distinct skill levels exist. The skill value is typically the same as
+#       the trainer's base money value.

+# Skill flags:
+#   PredictMoveFailure
+#   ScoreMoves
+#   PreferMultiTargetMoves
+#   HPAware (considers HP values of user/target for "worth it?" score changes)
+#   ConsiderSwitching (can choose to switch out Pokémon)
+#   ReserveLastPokemon (don't switch it in if possible)
+#   UsePokemonInOrder (uses earliest-listed Pokémon possible)
+#
+# Anti-skill flags are skill flags with "Anti" at the beginning. An "AntiXYZ"
+# flag will negate the corresponding "XYZ" flag.
