This is totally a rip-off, copy/paste from https://technet.microsoft.com/en-us/library/hh273375.aspx but I wanted it here so that I know where to look for it quickly.
| Built-in Variable Name | Description |
|---|---|
_SMSTSAdvertID
|
Stores the current running task sequence deployment unique ID. It uses the same format as a Configuration Manager software distribution deployment ID. If the task sequence is running from stand-alone media, this variable is undefined.
Example:
ABC20001
|
_TSAppInstallStatus
|
For System Center 2012 R2 Configuration Manager and later:
The task sequence sets the _TSAppInstallStatus variable with the installation status for the application during the Install Application task sequence step. The task sequence sets the variable with one of the following values:
|
_SMSTSBootImageID
|
Stores the Configuration Manager boot image package ID if a boot image package is associated with the current running task sequence. The variable will not be set if no Configuration Manager boot image package is associated.
Example:
ABC00001
|
_SMSTSBootUEFI
|
For System Center 2012 Configuration Manager SP1 and later:
The task sequence sets the SMSTSBootUEFI variable when it detects a computer that is in UEFI mode.
|
_SMSTSClientGUID
|
Stores the value of Configuration Manager client GUID. This variable is not set if the task sequence is running from stand-alone media.
Example:
0a1a9a4b-fc56-44f6-b7cd-c3f8ee37c04c
|
_SMSTSCurrentActionName
|
Specifies the name of the currently running task sequence step. This variable is set before the task sequence manager runs each individual step.
Example:
run command line
|
_SMSTSDownloadOnDemand
|
Set to true if the current task sequence is running in download-on-demand mode, which means the task sequence manager downloads content locally only when it must access the content.
|
_SMSTSInWinPE
|
This variable is set to true when the current task sequence step is running in the Windows PE environment, and it is set to false if not. You can test this task sequence variable to determine the current operating system environment.

Example:
0
|
_SMSTSLastActionSucceeded
|
The variable is set to true if the last action succeeded and to false if the last action failed. If the last action was skipped because the step was disabled or the associated condition evaluated to false, this variable is not reset, which means it still holds the value for the previous action.
|
_SMSTSLaunchMode

|
TSErrorOnWarning
|
For System Center 2012 R2 Configuration Manager and later:
Use this variable to specify whether the task sequence engine considers a detected warning as an error during the Application Installation task sequence step. The task sequence sets the _TSAppInstallStatus variable to Warning when one or more applications, or a required dependency, did not install because a requirement was not met. When you set the TSErrorOnWarning variable to True and the _TSAppInstallStatus variable is set to Warning, it is treated as an error. A value of False is the default behavior.

|
OSDPreserveDriveLetter
|
For System Center 2012 Configuration Manager SP1 and later:
This variable determines whether or not the task sequence uses the drive letter captured in the operating system image WIM file when applying that image to a destination computer. In Configuration Manager with no service pack, the drive letter captured in the WIM file is used when applying the operating system image WIM file. In Configuration Manager SP1, you can set the value for this variable to False to use the location that you specify for the Destination setting in the Apply Operating System task sequence step. For more information about the Apply Operating System task sequence step, see the Apply Operating System Image section in the Task Sequence Steps in Configuration Manager topic.
|

|
SMSTSRebootRequested
|
Indicates that a restart is requested after the current task sequence step is completed. If a restart is required, just set this variable to true, and the task sequence manager will restart the computer after this task sequence step. The task sequence step must set this task sequence variable if it requires the restart to complete the task sequence step. After the computer is restarted, the task sequence will continue to run from the next task sequence step.
|
SMSTSRetryRequested
|
Requests a retry after the current task sequence step is completed. If this task sequence variable is set, theSMSTSRebootRequested must also be set to true. After the computer is restarted, the task sequence manager will rerun the same task sequence step.
