"""Built-in effect handlers for Mantimon TCG.

This module provides the standard effect handlers used by most cards.
Each handler is registered using the @effect_handler decorator and can
be referenced by effect_id in card definitions.

Effect handlers follow a consistent pattern:
1. Extract parameters from context
2. Validate the action is possible
3. Apply the effect to game state
4. Return an EffectResult with details

Available Effects:
    Damage:
    - deal_damage: Raw damage (poison, burn, recoil, bench spread)
    - attack_damage: Combat damage with modifiers, weakness, resistance
    - coin_flip_damage: Damage based on coin flips
    - bench_damage: Damage to benched Pokemon

    Healing & Status:
    - heal: Heal damage from a Pokemon
    - apply_status: Apply a status condition
    - remove_status: Remove a status condition

    Card Movement:
    - draw_cards: Draw cards from deck to hand
    - discard_from_hand: Discard cards from hand
    - shuffle_deck: Shuffle a player's deck

    Energy & Modifiers:
    - discard_energy: Discard energy from a Pokemon
    - modify_hp: Change a Pokemon's HP modifier
    - modify_retreat_cost: Change a Pokemon's retreat cost modifier

    Evolution:
    - devolve: Remove evolution stages from a Pokemon

#
# The handlers below (coin_flip_damage, bench_damage) apply damage but do NOT
# currently detect knockouts. This is intentional for now because:
#
# 1. The engine doesn't yet execute attack effects - only base damage is applied
# 2. When effect execution is added, the engine should handle knockout detection
#    AFTER all effects resolve, not during each effect
# 3. The deal_damage/attack_damage handlers set knockout flags as informational
#    markers that the engine can use to identify which Pokemon to check
#
# When implementing effect execution in engine.py:
# - Execute all effects and collect EffectResults
# - Check details["knockout"] flag in each result
# - Call process_knockout() for each unique knockout_pokemon_id
# - Handle both active and bench knockouts (including multi-knockout scenarios)
