Touchstone runs on your own machine — the client starts it, so there is no endpoint to ping. 29 installs a week from pypi. Last commit 29 Jun 2026.
Verifiable text/code/measurement tools for agents, each reproducing a named authority.
Today is the operative word: we check Touchstone every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
