+- [ ] `packs generate_cache`, which can be used to update `tmp/cache/packwerk` for faster `packwerk` output. It should produce the exact same `json` that `packwerk` produces today. 
+Current Progress:
+  - Current progress is detected using `scripts/packwerk_parity_checker.rb`
+  - Currently, `packs` detects roughly 87% of references in Gusto's monolith
+Remaining Challenges include:
   - [ ] Parsing ERB
   - [ ] Parsing Rails associations and rewriting them as constant references using a pluralizer. Initially, non-standard inflections will likely not be supported (although I may support it through hard-coded map in `packwerk.yml`)
   - [ ] Replicating packwerk's behavior with respect to not recording "local definitions"
