This entity is
not in the
FGD by default.
It should not be put directly in a map because trigger_hurt already exists as a more accessible option.script_trigger_hurt is a point entity available in 
Left 4 Dead 2. It's a trigger_hurt, readjusted for vscripts by being stripped of any unnecessary brush data. Other than that, what applies to trigger_hurt is applicable to script_trigger_hurt. Since its a brush entity technically, using the keyvaluesminsandmaxsstill works.
When compiling Entity Groups, trigger_hurt entities are converted to script_trigger_hurt.
Keyvalues

parentname or target).

- Origin (origin) <vector>
- Center of the bounding box specified by extent
- Angles (angles) <vector>
- Angles of the bounding box specified by extent
- Damage (damage) <integer>
- The amount of damage done to entities that touch this trigger. The damage is done every half-second. See also Damage Model for extra details on how damage can be dealt. Use negative value to heal.
- Damage Cap (damagecap) <integer>
- Maximum damage dealt per second. This field is only used if you select the Doubling w/Forgiveness damage model, via the spawnflag.

- Damage Model (damagemodel) <choices>
- How damage is dealt. Normal always does the specified amount of damage each half second. Doubling starts with the specified amount and doubles it each time it hurts the toucher. Forgiveness means that if the toucher gets out of the trigger the damage will reset to the specified value. Good for making triggers that are deadly over time without having to cause massive damage on each touch.
- 0 : Normal
- 1 : Doubling w/forgiveness
- Zero Damage Force (nodmgforce) <boolean>
- Should the damaged entity receive no physics force from this trigger.
BaseTrigger
- Filter Name (filtername) <filter>
- A filter entity to test potential activators against.
- Start Disabled (StartDisabled) <boolean>
- Stay dormant until activated (with the
Enableinput).

Outputs
- OnHurt
- Fired whenever this trigger hurts something other than a player.
- OnHurtPlayer
- Fired whenever this trigger hurts a player.
BaseTrigger
- OnStartTouch
- !activator = entity that caused this output
!caller = this entity
Fired when a valid entity starts touching this trigger.
- OnStartTouchAll
- !activator = entity that caused this output
!caller = this entity
Fired when a valid entity starts touching this trigger, and no other entities are touching it. If there are any other entities touching the trigger when a new one begins to touch, only OnStartTouch will fire.
- OnEndTouch
- !activator = entity that caused this output
!caller = this entity
Fired when a valid entity stops touching this trigger.
Note:Will also fire for entities touching it when trigger is disabled via Disable input  Warning:This includes entities which are deleted while inside the trigger. In this case !activator will be invalid.Warning:OnEndTouch can fire before OnStartTouch under certain circumstances[How?] where both are fired on the same tick and each have the same delay. Fix:Add a slight delay to OnEndTouch.
- OnEndTouchAll
- !activator = entity that caused this output
!caller = this entity
Fired when all valid entities stop touching this trigger.
- OnTouching (in all games since )
- !activator = !caller = this entity
Fired if something is currently touching this trigger when TouchTest is fired.
- OnNotTouching (in all games since )
- !activator = !caller = this entity
