Agent Fleet

v0.23.1

An image studio, where a session’s agent rewrites the generation draft as you talk and a person presses generate, and session deletion that always goes through the trash and never takes a worktree with it. Around them, a cleanup for the cache deleted sessions leave behind, a view of the disk Agent Fleet uses, translation for questions and peer messages, and selectable text in PDFs.

New

Section titled “New”
  • Image studio. The image generation pane’s Attach an agent binds a session to the draft: ask it to read your material and “put her in a harbour at dusk”, then “darker”, and the agent rewrites the prompt, negative, steps, cfg, size, LoRAs and references. A person always presses generate. Fields can be locked, every edit is in a history you can rewind to, model, seed and mask stay yours alone, and Switch agent rebinds the studio without losing the draft. claude and copilot, cursor and kiro attach as Terminal (CLI) only, opencode not as Managed, and Muse Code not yet.
  • Deleting a session always goes to the trash, and can be undone. Shell and SSM sessions deleted from a row, a bulk tidy-up or a working-copy delete now land in the trash as AI sessions do. Deleting a session no longer deletes its worktree; deleting a worktree moves its stopped sessions to the archive. The trash tab gains Delete permanently: older than 30 days — the trash never empties on its own.
  • The cleanup dialog clears the cache of deleted sessions — pasted images and images codex read — once nothing refers to them any more. Settings › Machine shows the disk Agent Fleet uses, with each folder’s path; a path opens in the file tree, and an image folder in the gallery.
  • Questions, answered questions and messages from other sessions have a Translate button when they came in another language. Only the display is translated; answers are matched against the original.
  • Text in a PDF can be selected and copied.
  • Release history in the user guide. The guide carries every release’s notes and this index, and the builtin assistants can answer “what changed in which version” from them (in a new conversation).

Improved

Section titled “Improved”
  • A session can run up to 10 children at once (was 6); the default stays 3.
  • Settings › Notifications › Notify when a child session is waiting for input can be turned off. Questions and approvals from a child still notify.
  • Thinking blocks take less room: a collapsed one is a single line with a preview, and the close bar appears only on long ones.
  • A pasted image chip opens in the lightbox in the mirror’s composer and the launch dialog.
  • Long file names in the left pane are shortened in the middle, keeping the extension and the end of the name, and the tooltip shows the full path.

Fixed

Section titled “Fixed”
  • The fleet operator and SRE assistant on Antigravity answered “no response from agy” whenever the model tried a command or read its reference material. They now answer, a refused command is declined in words, and when agy does fail its reason is shown.
  • Opening the thumbnail cache folder in the gallery kept making thumbnails of thumbnails.
