# Promote a fast session

> Promotes a lightweight fast (quick-ask) conversation into a full standard
conversation, binding it to the workspace's default agent so subsequent turns run in
the full agent environment seeded with the existing transcript. The caller must be a
participant of the conversation (returns 403 otherwise). The promotion is one-way
and idempotent: it is a no-op if the conversation is already standard. Requires the
conversations:write scope.
Promote a fast session to a full hq: flip `mode` off `fast`,
one-way. The conversation already holds its transcript, so the next
turn in Studio cold-boots a VM seeded with that history via the normal
path - no backfill. Idempotent: a no-op if it was already standard.
