attach - Entire

Attach an existing agent session that was not captured automatically by Entire.

entire session attach SESSION_ID [flags]

This command reads the session transcript, creates or updates a checkpoint, and links it to your last commit. Use it when:

Hooks were not installed when the session started
Hooks failed to fire
You want to keep a research-only session that did not produce file changes

If the last commit already has an Entire-Checkpoint trailer, the session is added to that existing checkpoint. Otherwise, Entire creates a new checkpoint and offers to amend the last commit with the trailer.

Flag	Description
`-a, --agent NAME`	Agent that created the session. Defaults to `claude-code`. Run `entire agent list` to see registered agents, including external agents.
`-f, --force`	Skip confirmation and amend the last commit with the checkpoint trailer
`--review`	Tag the attached session as an agent review.
`--skills SKILL`	Declare which review skills were run. Repeatable; only used with `--review`.

# Attach a Codex session and amend HEAD automatically
entire session attach 019d6c43-1537-7343-9691-1f8cee04fe59 -a codex -f

# Attach a Claude Code session using the default agent
entire session attach 9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcbfe

# Attach a Codex session as a review
entire session attach 019d6c43-1537-7343-9691-1f8cee04fe59 -a codex --review

entire session attach requires the repository to already have at least one commit. If Entire cannot find the transcript for the agent you specify, it will try to auto-detect the correct agent from known transcript locations.
