Runtime description

The following is the tool's own agent-facing description, reproduced from the reviewed registry. It can contain implementation terminology; it does not expand the public stability commitment.

Read the agent-facing description

WORKFLOW: save -> resume in new session for agent handoff.
ANTIPATTERN: NOT for internal session persistence (use ctx_session).
Self-contained JSON bundles: session state, summaries,
knowledge. Actions: save, resume, list, info.
Saves tokens: portable across sessions/agents.
