Clean Comments

C1: No Inappropriate Information

Comments shouldn't hold metadata. Use Git for author names, change history, ticket numbers, and dates. Comments are for technical notes about code only.

C2: Delete Obsolete Comments

If a comment describes code that no longer exists or works differently, delete it immediately. Stale comments become "floating islands of irrelevance and misdirection."

C3: No Redundant Comments

# Bad - the code already says this
i += 1  # increment i
user.save()  # save the user
