Games like Left 4 Dead, Left 4 Dead 2, Counter Strike: Global Offensive, and Portal 2 are packaged with their own set of 'Authoring Tools' that are tailored for their specific engine builds and come packaged with the game on Steam. These games use most of the same programs below, but the source code can not be dumped.
In 2013, an update was released for Source SDK that allowed users to build OS X and Linux versions of their mods. Additionally, support was added for Valve's new Steampipe content distribution system as well as the Oculus Rift.

There are a total of four utilities in the Source SDK:
- Create a Mod: Dumps Source Engine code into a folder and places a mod directory under the SourceMods folder (Note: This appears neither in the Left 4 Dead (2) Authoring Tools, nor the Source 2009 version of the SDK.)
- Refresh SDK Content: Checks for data updates and downloads/refreshes new data
- Reset Game Configurations: Recreates game configurations with the basic games; mods mentioned in the configurations are removed unless manually edited
- Edit Game Configurations: Edits individual game configurations, primarily for Hammer
The Source SDK currently has three engine versions. A user can choose the 2006 version of the Source engine, which is only used by Half-Life: Source, Half-Life Deathmatch: Source, and various mods built on old Source 2006 code. All other Source games were updated to the most recent 2009 version of the Source engine, with the exceptions of Episode Two, which used the 2007 version between May 11, 2010 and June 23, 2010, and various mods built on old Source 2007 code. Half-Life 2: Deathmatch was updated to the 2009 version of the Source engine on September 30, 2010. Although currently, all multiplayer Source games were updated to the Source Engine MP.
There are three applications in the Source SDK, Valve Hammer Editor, Model Viewer, and Face Poser.
Valve Hammer Editor
The Valve Hammer Editor is a program included in the Source SDK that allows users to create maps for the Source Engine. It can be used with many different game configurations, for Source games like Team Fortress 2, Counter-Strike: Source, and Portal.
The Model Viewer is a program that allows users to view models and can be used for a variety of different purposes, including development.
Developers may use the program to view models and their corresponding animations, attachment points, bones, and so on. It can also be used to view props, weapons, buildings, and just about any other 3D object found except something which is a brush (an object created in Hammer that makes up the actual world - something like a floor, wall, room, skybox or terrain). The Model Viewer can't view game textures either (Hammer is used for that purpose instead).
Face Poser is the tool used to access facial animations and choreography systems.
This tool allows one to:
- Edit facial expressions, gestures and movements for characters (known as actors), allowing one to mix or blend several expressions on the fly.
- Lip synch speech with the speech the characters use (and blend the speech with other facial expressions). The phonemes used for lip-synching can be extracted from existing spoken .wav files, and the tool takes care of the real-time association between the spoken phonemes and the movements of the lips.
- Sequence expressions and other acting cues and preview what the scene will look like in the Game engine. A scene can refer to multiple actors and thus can be used to block out fairly complicated interactions and dialogue between game characters.

Source Engine Games that come with "Authoring Tools"
Note that any packages including one or more of the above games come with the Source SDK and also that Half-Life: Source, Half-Life Deathmatch: Source and the free release of Portal does not come with the Source SDK.
With the release of the 2013 version, Valve announced that the Source SDK was going to be removed soon, and replaced by individual authoring tools for every source game.
