Project Auditor reports several types of recommendations. Each of them is uniquely identified by a string ID containing 3 letters, followed by 4 digits.

The main types of recommendations are related to Code and Settings. Their IDs start with PAC and PAS respectively (Project Auditor Code/Setting).

Note that there are different ranges within both Code and Settings diagnostic IDs:

• Code:
  • PAC0xxx: for Unity API
  • PAC1xxx: for System.*
  • PAC2xxx: other IDs defined in code rather than in the json
• Settings:
  • PAS0xxx: Unity settings
  • PAS1xxx: other settings IDs defined in code rather than in the json
• Assets:
  • PAA0xxx: texture related settings
  • PAA1xxx: mesh related settings
  • PAA2xxx: shader related settings
  • PAA3xxx: file system related settings (Resources folders, StreamingAssets, Addressables, etc)
