pilot-event-filter

name	pilot-event-filter
description	Filter and transform events before delivery using pattern matching and jq transforms. Use this skill when: 1. You need to filter events by content, not just topic wildcards 2. You need to transform event payloads before processing 3. You need to route events conditionally based on content 4. You need to reduce event noise by selective forwarding Do NOT use this skill when: - Topic wildcards alone are sufficient (use pilot-event-bus instead) - You need all events without filtering (subscribe directly) - You need persistent storage (use pilot-event-log instead)

license	AGPL-3.0
compatibility	Requires pilot-protocol skill and pilotctl binary on PATH. The daemon must be running (pilotctl daemon start). Requires jq for JSON filtering and transformation.

Pilot Event Filter

Filter and transform Pilot Protocol event streams using jq-based pattern matching.

Commands

Subscribe with filtering

pilotctl --json subscribe <source-hostname> <topic> --timeout 60 | \
  jq -c '.data.events[] | select(<filter-expression>)'

Transform and republish

pilotctl --json subscribe <source> <topic> --timeout 60 | \
  jq -c '.data.events[] | <transform-expression>' | \
  while IFS= read -r event; do
    pilotctl --json publish <destination> "<new-topic>" --data "$event"
  done

Workflow Example

Filter critical alerts and forward to on-call agent:

#!/bin/bash
SOURCE_AGENT="monitoring-hub"
ONCALL_AGENT="oncall-agent"

pilotctl --json subscribe "$SOURCE_AGENT" "alerts.*" --timeout 600 | \
  jq -c '.data.events[]' | \
  while IFS= read -r event; do
    severity=$(echo "$event" | jq -r '.data | fromjson | .severity // "unknown"')

    if [ "$severity" = "critical" ]; then
      pilotctl --json publish "$ONCALL_AGENT" "oncall.critical" --data "$event"
    fi
  done
