Codsworth will become available as a companion after either: completing the quest 超越時空, reaching Diamond City or meeting Nick Valentine before reaching Concord. It is not necessary to complete the quest When Freedom Calls, simply getting close enough to the Museum of Freedom to start hearing gunfire (up to the playground in Concord should be close enough) and returning to Codsworth will suffice.
作為一個典型的巧手先生，它裝備有火焰噴射器和圓鋸，在接近敵人的時候，它可以有效地使用火焰噴射器灼燒他們，再以圓鋸切割一切處在它的視線範圍之內的敵人。嘎抓有著驚人的韌性，如果不是因為被重型武器攻擊，它在相當長的一段時間之中都可以保持戰鬥的活力。因此，在遊戲的初期，嘎抓是一個相當強力的隊友，但是在戰鬥中它不能被治療針治癒，因為它畢竟是一個機器人。However, with Automatron installed, the player character can repair him with a robot repair kit (schematics aren't required, therefore one can create them as soon as a chemistry station can be accesed, with no level requirement).
嘎抓對於攻擊有著25的抗性，約等於一個裝備了全套皮甲的人類同伴，然而，它的能量抗性僅僅只有5，遠遠低於裝備了任意一套裝甲的人類同伴。巧手先生的HP和人類同伴類似，因此在耐久性上，裝備了全套金屬裝甲或重甲的同伴會遠超於它。Codsworth's innate damage/energy resistance receives a moderate boost at very high player levels, but is less than that provided by a good suit of armor.
它有時會為主角提供純水，filtered from the ground water as he can be heard saying that pools of water are filling up in his reserves. He also appears able to extract water from the ambient air, as he occasionally mentions that his condensers are still working.
If Codsworth takes damage, he may say, "'Tis but a scratch," possibly as a reference to the Black Knight in the movie Monty Python and the Holy Grail. It could also be a reference to Mercutio's death scene in Shakespeare's Romeo and Juliet.
The 'worth' part of the name is typical among pop-culture butlers.
Codsworth will correctly say uncommon spellings of names such as Cori and Borri. Cori being the name of a villager from The Elder Scrolls: Arena and Borri being the name of one of the Greybeards from The Elder Scrolls: Skyrim.

pcps4 As stated in the notes section, Codsworth will become available as a companion after discovering Concord on the map. It is not necessary to complete or even start When Freedom Calls. Simply going to Concord and returning to Codsworth is enough.
