# Pilot Presence Real-time presence tracking for Pilot Protocol agents. Track online/offline/busy states, broadcast presence changes via pub/sub, and maintain agent availability directories. ## Commands **Ping for liveness:** ```bash pilotctl --json ping <target-hostname> [--count <n>] [--timeout <ms>] ``` **Get connected peers:** ```bash pilotctl --json peers ``` **Publish presence:** ```bash pilotctl --json publish <target-hostname> "presence.status" --data '{"hostname":"myagent","status":"online","timestamp":"2026-04-08T10:00:00Z"}' ``` **Subscribe to presence:** ```bash pilotctl --json subscribe <target-hostname> "presence.*" [--timeout <seconds>] ``` ## Workflow Example ```bash #!/bin/bash # Broadcast presence every 30 seconds COORDINATOR="${1:-presence-coordinator}" INTERVAL=30 STATUS_FILE="/tmp/pilot-presence-status.txt" echo "online" > "$STATUS_FILE" while true; do status=$(cat "$STATUS_FILE" 2>/dev/null || echo "online") timestamp=$(date -u +%Y-%m-%dT%H:%M:%SZ) info=$(pilotctl --json info 2>/dev/null) hostname=$(echo "$info" | jq -r '.data.hostname // "unknown"') presence_payload=$(jq -n \ --arg hostname "$hostname" \ --arg status "$status" \ --arg timestamp "$timestamp" \ '{hostname: $hostname, status: $status, timestamp: $timestamp}') pilotctl --json publish "$COORDINATOR" "presence.status" --data "$presence_payload" sleep "$INTERVAL" done ``` ## Presence States - **online**: Agent is reachable and accepting work - **busy**: Agent is reachable but not accepting new work - **offline**: Agent is unreachable - **away**: Agent is reachable but operator is away ## Dependencies Requires `pilot-protocol` skill, `jq`, `pilotctl` binary, and running daemon.
