Accurate trait gives flat bonuses, so they work right out of the box.  Agile gives percentage bonuses.  The problem is the bonus is a multiplier, so this racial trait does absolutely nothing unless and until you manage to research Jamming technology and mount some on your ship.  Then it takes your 10% Jammer and makes it a 12.5% Jammer.  Not exactly blowing the doors off in terms of wonderfulness.

Agile looks like this:

<RaceTrait>
<InternalName>Agile1</InternalName>
<DisplayName>Agile1_Name</DisplayName>
<Description>Agile1_Desc</Description>
<Mod>
<EffectType>Jamming</EffectType>
<Scope>Global</Scope>
<Target>
<TargetType>Ship</TargetType>
</Target>
<BonusType>Multiplier</BonusType>
<Value>0.25</Value>
</Mod>
</RaceTrait>

The fix looks like this:

<BonusType>Flat</BonusType>
