Tests 3, 4, 5 previously returned synthetic pane PIDs (99999/99998/99997) from their fake list-panes shims but did not set MOSAIC_HEARTBEAT_RUN_DIR, causing the launcher to fall back to the real ~/.config/mosaic/fleet/run and potentially spawn a background sidecar against an arbitrary host PID. Fix: - list-panes in tests 3/4/5 now returns empty string → PANE_PID stays unset → no sidecar is spawned for tests where heartbeat is not under test. - MOSAIC_HEARTBEAT_RUN_DIR is exported to a per-test mktemp dir in each fake-tmux test (3, 4, 5) as defence-in-depth so even if the sidecar code path changes, it can never write to the real fleet run dir. - New temp dirs are registered in CLEANUP_DIRS so they are removed by the existing EXIT trap. - Tests 6 and 7 (the dedicated heartbeat tests) are unchanged: test 6 uses a real tmux pane PID + its own HB_RUN_DIR, test 7 intercepts via a fake setsid shim that captures args and exits immediately. - All 7 tests pass; verify-sanitized.sh passes; no stray sidecar processes or unexpected .hb files are written to ~/.config/mosaic/fleet/run.

CLI package for the Mosaic self-hosted AI agent platform.
Usage
mosaic wizard # First-run setup wizard
mosaic gateway install # Install the gateway daemon
mosaic config show # View current configuration
mosaic config hooks list # Manage Claude hooks
Headless / CI Installation
Set MOSAIC_ASSUME_YES=1 (or ensure stdin is not a TTY) to skip all interactive prompts. The following environment variables control the install:
Gateway configuration (mosaic gateway install)
| Variable | Default | Required |
|---|---|---|
MOSAIC_STORAGE_TIER |
local |
No |
MOSAIC_GATEWAY_PORT |
14242 |
No |
MOSAIC_DATABASE_URL |
(none) | Yes if tier=team |
MOSAIC_VALKEY_URL |
(none) | Yes if tier=team |
MOSAIC_ANTHROPIC_API_KEY |
(none) | No |
MOSAIC_CORS_ORIGIN |
http://localhost:3000 |
No |
Admin user bootstrap
| Variable | Default | Required |
|---|---|---|
MOSAIC_ADMIN_NAME |
(none) | Yes (headless) |
MOSAIC_ADMIN_EMAIL |
(none) | Yes (headless) |
MOSAIC_ADMIN_PASSWORD |
(none) | Yes (headless) |
MOSAIC_ADMIN_PASSWORD must be at least 8 characters. In headless mode a missing or too-short password causes a non-zero exit.
Example: Docker / CI install
export MOSAIC_ASSUME_YES=1
export MOSAIC_ADMIN_NAME="Admin"
export MOSAIC_ADMIN_EMAIL="admin@example.com"
export MOSAIC_ADMIN_PASSWORD="securepass123"
mosaic gateway install
Hooks management
After running mosaic wizard, Claude hooks are installed in ~/.claude/hooks-config.json.
mosaic config hooks list # Show all hooks and enabled/disabled status
mosaic config hooks disable PostToolUse # Disable a hook (reversible)
mosaic config hooks enable PostToolUse # Re-enable a disabled hook
Set CLAUDE_HOME to override the default ~/.claude directory.
