What its author says it does

Copied from the file, not written here

Persistent NDJSON event logging with rotation, compression, and retention policies. Use this skill when: 1. You need persistent storage of event streams 2. You need log rotation and compression for long-term retention 3. You need to audit event history with timestamps 4. You need to export events for external analysis Do NOT use this skill when: - You need real-time event processing (use pilot-event-bus instead) - You need short-term replay (use pilot-event-replay instead) - You need filtered logs (use pilot-event-filter first, then log)

Pilot Event Log

Persistent NDJSON logging of Pilot Protocol event streams with rotation and compression.

Commands

Subscribe and Log

pilotctl --json subscribe <source> <topic> --timeout <seconds> | jq -c '.data.events[]' >> <log-file.ndjson>

Query by Time

jq -c --arg start "2026-04-08T00:00:00Z" --arg end "2026-04-08T23:59:59Z" \
  'select(.timestamp >= $start and .timestamp <= $end)' events.ndjson

Query by Topic

jq -c 'select(.topic | startswith("alerts."))' events.ndjson

Rotate Logs

[ "$(du -m "$log_file" | cut -f1)" -ge "$MAX_SIZE_MB" ] && mv "$log_file" "$log_file.$(date +%s)" && gzip "$log_file.$(date +%s)" &

Compress Old Logs

find /var/log/pilot-events -name "events-*.ndjson" -mtime +1 -exec gzip {} \;

Retention Cleanup

find /var/log/pilot-events -name "events-*.ndjson.gz" -mtime +90 -delete

Workflow Example

#!/bin/bash
# Production event logging

SOURCE="${1:-production-app}"
LOG_DIR="/var/log/pilot-events/$SOURCE"
MAX_SIZE_MB=500

mkdir -p "$LOG_DIR"
log_file="$LOG_DIR/current.ndjson"

while true; do
  pilotctl --json subscribe "$SOURCE" "*" --timeout 600 | jq -c '.data.events[]? // empty' | \
  while IFS= read -r event; do
    echo "$event" | jq -c '. + {logged_at: (now | todate)}' >> "$log_file"

    size_mb=$(du -m "$log_file" 2>/dev/null | cut -f1)
    if [ "${size_mb:-0}" -ge "$MAX_SIZE_MB" ]; then
      rotated="$LOG_DIR/events-$(date +%Y%m%d-%H%M%S).ndjson"
      mv "$log_file" "$rotated" && gzip "$rotated" &
    fi
  done
  sleep 5
done

Dependencies

Requires pilot-protocol skill, jq (1.6+), gzip, and running daemon.
