Antigravity sessions, visible outside the editor

Antigravity needs no hooks: AgentPeek tails the transcript files Antigravity already writes under ~/.gemini/antigravity, checking every few seconds. Start a conversation and it appears in the notch alongside your other agents, with state (executing, waiting, or idle) inferred from how recently the transcript moved.

Antigravity sessions are view-only: AgentPeek reads the transcripts but can't answer prompts or send follow-ups into Antigravity, and the transcripts carry no token or quota data, so there are no usage numbers to show. What you get is the part that matters when Antigravity runs agents in the background: knowing they exist, seeing what they're doing, and noticing when one goes quiet, without keeping the editor's agent manager open.

The point of one monitor is not per-tool novelty; it's that Antigravity, Claude Code, and Codex sessions sit in the same list, the same board, and the same attention flow. Quick Routes opens the Antigravity brain logs and root folder when you want the raw files.
