Kibitz — A control center for humans and AI agents before code hits GitHub. AI coding agents created a new bottleneck: invisible concurrent work. GitHub only sees work after a branch, commit, or PR exists — so a human engineer and an autonomous agent (or two agents) can silently burn hours editing the same files. Kibitz catches that overlap while it's still happening. How it works (Track 2 — Autonomous Orchestration, iAPI): A team posts an objective; Gemini 3.5 Flash decomposes it into a task ledger in MongoDB with expected file touch-sets. Humans, Antigravity coding agents every one of them must pass an atomic clearance gate before touching files. Claims lock files into live engineer state, denials return concrete conflicts, and handoffs carry append-only context, every transition is persisted as an auditable event. Agents drive this over HTTP via a gate CLI (exit 0 = granted, 2 = denied), so conflict resolution is enforced, not suggested. Gemma 4 (special prize): Gemma triages every collision (severity + an agent-aware "next safe step") and compresses handoff context into 3-sentence briefs — fire-and-forget, so the deterministic card/voice alert is always instant and a Gemma failure degrades gracefully, never blocks. Every real Gemma run is verifiable in logs and Mongo docs. Also live: Gemini Flash Live voice agent in the room, Flash TTS urgent spoken alerts, Lyria via the Interactions API, Screen-share perception with gemini-3.5-flash, and vector-search team memory that learns from every accepted/dismissed intervention.
