Module session_tail 

Tail summary of a session’s provider transcript, for a human or operator who cannot reach the machine (a session went silent: what did it do last, where did it stop?).

The session is found in the resume journal (session-resume.json) by its provider session id (or its instance); the transcript is the provider’s own file: claude ~/.claude/projects/*/<id>.jsonl, codex ~/.codex/sessions/**/rollout-*-<id>.jsonl (located and read through codex-session-restore). Other providers answer unsupported.

The summary holds only recent prompts, tool calls with their status, errors, the MCP tools the session had and where it stopped. Never tool output, env, memory or notes: text inside <system-reminder> is dropped, a tool call naming a memory or notes path keeps only its name, secrets are scrubbed and host paths shortened. Access is decided by core (owner of the node or an operator grant on it); the node answers only core’s own link.
