Attach a session when useful agent context exists, but Entire did not link it automatically. ## When to attach a session Use `entire session attach` when: * hooks were not installed when the session started * hooks did not fire * a research session should be linked to the latest commit * a completed agent review should be preserved as review context ## Attach a session Attach reads an existing agent transcript, creates or updates a checkpoint, and links that context to the last commit. ```bash theme={null} entire session attach SESSION_ID --agent AGENT ``` If the last commit already has an `Entire-Checkpoint` trailer, the session is added to that checkpoint. Otherwise, Entire creates a checkpoint and can amend the last commit with the trailer. ## Attach without prompts Use `--force` when you want Entire to skip confirmation and amend the last commit: ```bash theme={null} entire session attach SESSION_ID --agent AGENT --force ``` ## Attach a review session Use `--review` when the session was an agent review of existing work: ```bash theme={null} entire session attach SESSION_ID --agent codex --review ``` If the review used specific Skills, declare them with `--skills`: ```bash theme={null} entire session attach SESSION_ID --agent codex --review --skills review ``` ## Continue with Find the session ID to attach. See attach flags and examples. Bring past local agent sessions into Entire as read-only checkpoints.
