agent-compose picked the role an agent ran as, with its charter and personality, and compiled the context its harness loaded into one immutable bundle of plain files. You could read and diff that bundle before a run, and it granted no credential, mount, or command.
It is no longer offered, and its source is no longer public. This page stays as a record of what it did. For bounding what an agent can run, see umbra. For grading what it did, see housecast.
