check-code-hygienelisted

Analyze the codebase for code hygiene issues. Generate a report highlighting problems with standardization, human readability, maintenance complexity, and defensive coding. ## Process 1. **Read CLAUDE.md** to understand the project's documented conventions and architecture. 2. **Scan the source code** (`src/`) for these categories of issues: ### Standardization - Inconsistent naming conventions (camelCase vs snake_case, abbreviations) - Inconsistent patterns for similar operations (e.g., error handling done differently in similar contexts) - Inconsistent import ordering or module organization - Mixed paradigms without clear justification ### Human Readability - Functions that are too long or do too many things (>50 lines of logic) - Deeply nested code (>3 levels of nesting) - Unclear variable/function names that require reading the implementation to understand - Missing or misleading comments on complex logic - Magic numbers or strings without named constants - Complex boolean expressions that should be extracted to named variables ### Maintenance Complexity - Tight coupling between modules that should be independent - Circular dependencies - God objects or functions that know too much about other modules - Duplicated logic that should be shared - Files that mix multiple unrelated concerns (check against the "one primary export per file" convention in CLAUDE.md) ### Defensive Coding - Unvalidated external input (API request bodies, query params, file contents) - Missin
