Mistral Vibe: Archive Local Sessions

Mistral VibeView original changelog

Mistral Vibe v2.25.8 added the ability to archive local sessions, hiding them from the active session list without deleting them, and archiving now automatically cleans up the managed git worktree tied to that session. The change gives developers a way to keep a long project history tidy as their local session list grows, rather than letting completed or abandoned sessions pile up alongside active work.

Key Takeaways

  • Session archiving lets developers hide completed local sessions from the active list without deleting them.
  • Archiving a session now automatically cleans up its git worktree, removing a manual git worktree remove step.
  • The feature builds on Mistral Vibe's dedicated worktree plugin, shipped in early September, extending its automated lifecycle management.
  • It ships alongside a Vibe Desktop unseen-indicator feature, giving developers both "needs attention" and "safe to archive" signals for local sessions.
  • Aimed at heavy users running many parallel sessions, where the active list otherwise grows unmanageably long over time.
  • Part of a broader v2.25.8 release focused on session and worktree list management rather than a single standalone feature.

Session List Cleanup Gets Automated

Mistral Vibe shipped a way to archive local sessions in v2.25.8, letting developers hide completed or abandoned sessions from their active session list without losing them outright. Anyone who runs many parallel Vibe sessions, especially alongside the --worktree flag or the built-in worktree plugin Mistral Vibe shipped a few weeks earlier, tends to accumulate a long tail of sessions that are done but still cluttering the picker.

Worktree Cleanup Included

Archiving a session now also triggers automatic cleanup of any git worktree that session was managing. Previously, a developer who wrapped up work in a worktree-backed session had to manually run git worktree remove (or rely on Vibe Desktop's separate worktree-retention settings) to reclaim that state. Folding worktree teardown into the archive action removes a manual step that developers were doing by hand, and it closes the loop on the broader worktree-lifecycle work Mistral Vibe has been investing in since it shipped the dedicated worktree plugin in early September.

Where It Fits

The change lands in the same release as a companion Vibe Desktop update that adds unseen-work indicators for local sessions still in progress, suggesting Mistral Vibe is treating the local session list as an area that needs ongoing attention rather than a one-time feature. Together, archiving and unseen indicators give developers two complementary signals: which sessions still need a look, and which ones can be tucked away for good.
