tot-sdk: Official Tool of Tools Framework Package

What is it?

tot-sdk contains the code necessary for creation of agents/tools capable of being used within the Tool of Tools framework.

Security: CA certificate update

CVE-2026-91403 also affects Python applications that trust an outdated certificate store. Keep every environment that runs this package at or above these versions:

• certifi 2026.10.19 or later. This package requires it, but an environment that already has an older certifi must be upgraded.
• pip 26.2.2 or later, in every virtual environment.
• uv 0.13.4 or later, if you use uv.
• Your operating system's corrected CA certificate package, and rebuilt container images that do not reuse cached layers.

See the Python security announcement for the checksum-pinned command to safely bootstrap the corrected pip.
