Use

Copy this directory into your project (or pin a release tarball) and load it with the Pi coding agent:

pi --no-extensions --extension pi/core

Offline load test (as run in CI):

PI_OFFLINE=1 pi --offline --mode rpc --no-session --no-context-files --no-extensions \
  --extension pi/core </dev/null >/dev/null

Regenerate

pi/core is generated from manifests/pi-core.json and committed so release tarballs contain it verbatim. After changing the manifest or any included source content, run:

node scripts/build-pi-core.js

and commit the result. CI verifies the committed profile is up to date.
