History‑linked checkpoints and file state restore

What feature would you like to see?

Provide a mechanism that ties conversation history to file state:

• Automatically create a checkpoint whenever the agent modifies files (e.g., via apply_patch or approved shell writes).
• When jumping to a past message from history/backtrack, restore the workspace to the file state at that message. Make this restore behavior configurable: automatic or prompt/manual.

Implementation note

• Backend is implementation‑agnostic. A Git‑based approach is one practical option, but any local snapshot store that can recreate exact file states is acceptable.

Slash commands (especially for manual mode)

• /checkpoint restore <message-id|checkpoint-id> → Restore files to the state associated with a specific history message or checkpoint (confirmation shown).
• /checkpoint save [message] → Optional manual checkpoint at the current workspace state.
• /checkpoint mode auto|manual → Toggle restore behavior when navigating history/backtrack.

Are you interested in implementing this feature?

Potentially—happy to help refine the design and contribute an implementation once maintainers confirm the scope and preferred storage backend.
