A ToolSet is a Traveller game mechanic, an organized system for generating game components other than player characters. 
- The player character generator is known as CharGen.
- ToolSets exist as hardcopy in-rulebook creation sequences and as automated, online utility programs.

History & Background (Dossier)
CharGen and various simulators for making various things across a broad spectrum from NPCs to objects to armor to weaponry to vehicles to starships and more have been a consistent feature of the game since 1977. 
Many ToolSets have been converted into online calculators and similar programs. 
ToolSets are a major part of T5 and many were created throughout the development and playtesting of the T5 Core Rules. Not all of them made it to the final cut and not all of them are featured in the T5 Core Rules. 
ToolSets, or their equivalents (which continue to be ToolSets even if not named thus), are one of the main points of divergence for different versions. For example: 
- Every version has some type of CharGen. In most versions, it is possible for a traveller to die during CharGen due to random dice rolls. In Mongoose Traveller, both first and Second Edition, this is at most a choice, never forced: if the rolls would have resulted in death, a traveller can instead go into medical debt to stay alive. GURPS Traveller does not use lifepath-style CharGen, avoiding the issue entirely, instead substituting a point-buy system.
- Mongoose Traveller Second Edition allows one to designate an arbitrary hull size, with simple formulas to calculate maneuver drive and jump drive requirements for a given performance (and power plant requirements for those and other systems, particularly energy weapons). The New Era and GURPS Traveller have more complex formulas, allowing for finer detail. Most other versions require one to pick among pre-made sizes of hull, maneuver drive, and jump drive, then look up the performance on tables, and select power plant to be at least equal to those (usually with no regard for other systems, including weapons). Some find one of these approaches far easier to use, or better suited to their use cases, than the others.
- For many, deciding between versions is primarily just deciding between ToolSets.
The Perils of CharGen
Traveller is very well known for the possibility of a character being killed before it leaves CharGen. Some might say infamous... This eventuality has become the butt of Tshirts and comic strips. 
Starship and vehicle generation, in many cases, grew quite complex and became known as gearheadery with the self-obsessed fans becoming known as gearheads.
