No Comments
- Identify comments that explain obvious code, restate syntax, or explain temporary workarounds that should be deleted.
- Distinguish legitimate constraints (hard external requirements, regulatory/spec references, non-obvious invariants) from redundant explanations.
- Convert valid constraint comments into types, tests, assertions, or lints whenever possible.
- Delete redundant commentary, commented-out dead code, and speculative notes.
- Verify that code remains readable and self-documenting through clear naming and small, focused functions.
