DETECTION CRITERIA (Specific)

1. Obvious Comments (EXCLUDE: BDD comments like #given, #when, #then, #when/then)

REMOVE:

• Comments restating the code: x += 1 # increment x
• Docstrings on trivial methods: """Returns the name.""" for def get_name(): return self.name
• Section dividers: # ===== HELPER FUNCTIONS =====
• Commented-out code blocks
• # TODO: future enhancement without concrete plan
• # Note: this is important without explaining WHY

KEEP:

• Comments explaining WHY (business logic, edge cases, workarounds)
• Links to issues/tickets: # See SPR-1234
• Non-obvious algorithm explanations
• Regex explanations
• Matches to existing code style

2. Over-Defensive Code

REMOVE:

• Null checks for values that CANNOT be None (e.g., Django request in view)
• if x is not None and x.attr is not None: when x is guaranteed
• Try-except around code that can't raise (e.g., dict literal access)
• isinstance() checks for statically typed parameters
• Default values for required parameters: def foo(x: str = "") when empty string is invalid
• Backward-compat shims: _old_name = new_name # deprecated
• # removed or # deleted comments for removed code
• Re-exports of unused items
• Verbose, duplicated, or redundant code / test cases

KEEP:

• Validation at system boundaries (user input, external API responses)
• Error handling for I/O operations
• Null checks for nullable DB fields
• assertions in test code to matching type expectations

3. Spaghetti Nesting (2+ levels deep)

REFACTOR:

• Nested if-else chains -> early returns / guard clauses
• if x: if y: if z: -> if not x: return / if not y: return
• Nested loops with conditionals -> extract to helper OR use comprehensions
• Complex ternary a if b else (c if d else e) -> explicit if-else
