simplify

Refactoring duplicated logic and dead code in git commits requires analyzing the git diff range to identify complexity, then applying targeted simplifications to long functions and inefficient patterns while preserving behavior.

Reviewing staged changes for code complexity involves reading the full files from the git diff, detecting deep nesting and magic values, and applying conservative fixes to improve readability and reuse.

You can simplify changed code files without breaking behavior by running available linters or tests after making atomic edits, verifying that refactors like dead code removal and condition reduction preserve functionality.

Finding and fixing inefficient patterns after a commit uses grep and git diff to locate redundant conditions and duplicated logic, then applies safe refactors and produces a summary of edits made with rationale.

Git diff based code review works for detecting long functions and deep nesting by inspecting changed files in full context, identifying complexity hotspots, and applying targeted refactors to improve code structure.

You should avoid automated code simplification when no linters or tests are available to verify behavior preservation, as the process relies on running verification tools to ensure refactors do not introduce defects.
