[nitpick] The '10x faster' claim lacks substantiation. Consider either providing benchmarks or using more conservative language like 'significantly faster' or 'optimized performance'.

Suggested change
- **jq-based JSON processing**: 10x faster than pure JS parsing

The jq command syntax may be incorrect. The subtraction operator '-' is not a standard jq operation for object difference. Consider using a proper jq expression or clarifying this is pseudocode.

Suggested change
jq --slurpfile old $OLD --slurpfile new $NEW -n '$new - $old'
jq --slurpfile old $OLD --slurpfile new $NEW -n '
($new[0] | to_entries | map(select(.key as $k | ($old[0]|has($k)|not))) | from_entries)
'
