# Pilot Event Replay

> Record and replay event streams for debugging, testing, and audit purposes. Use this skill when: 1. You need to capture event streams for later analysis 2. You need to replay events to test downstream consumers 3. You need to debug event-driven workflows 4. You need to audit event history with timestamps Do NOT use this skill when: - You need real-time event forwarding (use pilot-event-bus instead) - You need long-term storage with rotation (use pilot-event-log instead) - You need filtering before recording (use pilot-event-filter first)

# Pilot Event Replay

Record event streams to NDJSON files and replay them for debugging and testing.

## Commands

### Record events to file
```bash
pilotctl --json subscribe <source-hostname> <topic> --timeout <seconds> | \
  jq -c '.data.events[]' >> <recording-file.ndjson>
```

### Replay events from file
```bash
cat <recording-file.ndjson> | jq -c '.' | while IFS= read -r event; do
  topic=$(echo "$event" | jq -r '.topic')
  data=$(echo "$event" | jq -r '.data')

  pilotctl --json publish <target-hostname> "$topic" --data "$data"
  sleep <delay-seconds>
done
```

## Workflow Example

Record debug session:

```bash
#!/bin/bash
SOURCE="buggy-worker"
DURATION=300
RECORDING="/tmp/debug-session-$(date +%Y%m%d-%H%M%S).ndjson"

pilotctl --json subscribe "$SOURCE" "*" --timeout "$DURATION" | \
  jq -c '.data.events[]' >> "$RECORDING"

event_count=$(wc -l < "$RECORDING")
echo "Recorded $event_count events"
```

Replay to test agent:

```bash
#!/bin/bash
RECORDING="$1"
TEST_TARGET="test-agent"

jq -c '.' "$RECORDING" | while IFS= read -r event; do
  topic=$(echo "$event" | jq -r '.topic')
  data=$(echo "$event" | jq -r '.data')

  pilotctl --json publish "$TEST_TARGET" "$topic" --data "$data"
  sleep 0.5
done
```

## Dependencies

Requires pilot-protocol skill, jq, and a running daemon.
