uvx and go

Six packages. One IANA-registered family.

The FAF Python ecosystem — two implement Zenodo papers, all share the same standard.

What it is

Six packages on PyPI built on the same IANA-registered .faf and .fafm formats. Two of them — claude-fafm-sdk and gemini-faf-mcp — are reference implementations of Zenodo-published papers. The rest extend the family across voice, agents, and the Python SDK that ties them together.

Every number on this page is real, dated, and from pypistats.org without_mirrors only — no bot inflation, no mirror double-counting.

Why it exists

Every Python AI tool currently invents its own context shape. .faf is the IANA-registered standard that lets them share one — same file readable by Gemini, Claude, Grok. .fafm is the memory profile: durable agent memory in a portable, versionable file.

FAF on PyPI is six surfaces of the same standard. Different vendors, different runtimes, one format underneath.
