# Sessions in entire.io

> Review session timelines, transcripts, tool calls, files, and attribution in entire.io.

Use entire.io when you want to visually inspect what happened during an agent session and move between the session, checkpoint, and file changes.

## Open a Session

Open the checkpoint that contains the session you want to inspect, then use the session list to choose the agent work behind that checkpoint.

Each session row shows the agent, step count, opening prompt, and relative timestamp.

## Session Timeline

The timeline shows the conversation in order, including prompts, agent responses, expandable tool calls, and runtime tags. The metadata panel summarizes the agent, model, duration, and token usage when available.

Use timeline filters to focus on prompts, responses, intermediate steps, checkpoints, or specific tool-call types.

## Files and Attribution

Files modified during a session are reviewed through the checkpoint that owns the session. When a checkpoint includes multiple sessions, the diff shows the combined change, while session details preserve the per-session context.

Entire also calculates how much of a checkpoint came from the agent versus a human edit. Attribution helps reviewers decide when to inspect the transcript more closely.

The breakdown can include:

* agent-written lines
* human-added, modified, or removed lines
* agent percentage for the checkpoint or session

## Sub-Agent Sessions

When an agent spawns a sub-agent, Entire records it against the parent session and materializes its transcript into the parent's next checkpoint. The session list shows the parent, so review the sub-agent's file changes through the checkpoint that owns it. entire.io does not browse sub-agent records on their own yet.

[Agent Integrations](/agents/overview#compare-built-in-integrations) covers which agents record which sub-agents and which roll their tokens up.
