Mosaic

Mosaic provides a command-line tool for macOS that synchronizes coding-agent session state across machines and teams through a background local replica at /.mosaic. A single mosaic install command handles browser authorization, team selection, session source detection, and LaunchAgent registration, with agent-safe automation via mosaic install --yes . The tool supports scoped backups, team management, and diagnostic commands like mosaic doctor and mosaic refresh .

Problem

Developers and teams using coding agents lack a reliable, low-friction way to synchronize agent session state across machines or share it with teammates. Manual configuration, scattered session data, and inconsistent setup steps create overhead and risk of data loss or misalignment.

Solution

Mosaic provides a command-line tool that installs on macOS and maintains a background-synchronized local replica of team coding-agent sessions at ~/.mosaic. A single `mosaic install` command handles browser-based authorization, team selection, session source detection, LaunchAgent registration, and optional coding-agent skill installation. The tool exposes completed replicas only, avoiding partial data, and offers `mosaic doctor` and `mosaic refresh` for diagnosing and repairing setup issues. It supports scoped backups (selected folders or all sessions), team management, and verification via JSON status outputs.

Target Audience

Individual developers and engineering teams who use coding agents on macOS and need synchronized, shareable session state with minimal setup overhead.

Features

Installable via Homebrew (`brew install emergent-inc/tap/mosaic`) or a shell installer that requires no Node.js, npm, rclone, or MCP server
Background LaunchAgent (`com.ocean.daemon`) maintains sync and exposes a local replica at `~/.mosaic` without showing partial data
Single interactive `mosaic install` flow for browser authorization, team create/join/select, session source detection, and agent skill installation
Agent-safe mode with `mosaic install --yes` and `OCEAN_INSTALL_ONLY=1` bootstrap for automation
CLI commands for backup scope management (`mosaic scope selected/add/remove/all`), team listing, status, doctor checks, and clean uninstall
Instruction-only skill files for supported coding agents (e.g., cursor, claude-code), never overwriting user-owned skills or modifying agents, hooks, or extensions
