Improve techdocs-common Generator API for it to be used by techdocs-cli. TechDocs generator.run function now takes an input AND an output directory. Most probably you use techdocs-common via plugin-techdocs-backend, and so there is no breaking change for you. But if you use techdocs-common separately, you need to create an output directory and pass into the generator.
