scripts/capture-fixture.sh <name> [prompt]

Print mode

claude --output-format stream-json -p "say hello" 2>/dev/null > /tmp/claude-simple-text.jsonl

Interactive mode (control protocol)

mkfifo /tmp/claude-stdin
claude --output-format stream-json --input-format stream-json --verbose \
  < /tmp/claude-stdin 2>/dev/null | tee /tmp/claude-interactive.jsonl &
exec 3>/tmp/claude-stdin
# Send control_request JSON via fd 3, sleep between requests
exec 3>&-; kill %1 2>/dev/null; rm /tmp/claude-stdin

From DB

mysql -u root -h 127.0.0.1 -P 3306 code_quest -N -e \
  "SELECT raw FROM raw_entries WHERE raw LIKE '{\"type\":\"<type>\"%' LIMIT 1;"

Validation

# Every line must be valid JSON
while IFS= read -r line; do
  echo "$line" | jq . > /dev/null 2>&1 || echo "INVALID: $line"
done < /tmp/fixture.jsonl

# Check event type distribution
cat /tmp/fixture.jsonl | jq -r '.type' | sort | uniq -c

Sanitization

sed -i '' 's/"session_id":"[^"]*"/"session_id":"test-session-id"/g' fixture.jsonl
grep -l "sk-" fixture.jsonl  # Check for API key leaks

Destination

apps/summoner/src/__fixtures__/claude/
├── real/<name>.jsonl        # From DB or real CLI
