## What it is
The Adobe Font Development Kit for OpenType (AFDKO) is a set of command-line tools for building OpenType font files from PostScript and TrueType font data. It is distributed as a Python package on PyPI and includes tools for feature compilation, hinting, and font validation.

## Use cases
- build OpenType fonts from PostScript or TrueType source data
- compile OpenType feature files (FEA) into fonts
- autohint CFF fonts
- create variable fonts with feature support
- validate OpenType/CFF and TrueType fonts
- work with CID-keyed UFO fonts

## When to choose
- you are a type designer or font engineer building production OpenType fonts
- you need Adobe's reference toolchain for OpenType feature compilation and hinting
- you want to automate font builds in a Python-based pipeline

## When to avoid
- you only need to inspect or convert fonts rather than build them
- you need a GUI font editor rather than command-line tools
- you work with formats outside OpenType/PostScript/TrueType
