QA Code Review

QA Code Review

"Review code quality BEFORE running automated checks - catch issues early."

Review code quality before running type-check, lint, test, and build. This catches issues that automated tools might miss and ensures code quality standards are met.

When to Use

Use at the start of validation, before type-check/lint/test/build loops.

Quality Checks

Process

1. Identify changed files from the task
2. Grep for anti-patterns across changed files
3. Read each changed file to review context
4. Check for quality issues using the table above
5. Report findings with specific file locations and line numbers

Grep Patterns for Code Review

# TypeScript suppressions
grep -r "@ts-ignore\|@ts-expect-error" src/

# Any types
grep -r ": any\|<any>\|as any" src/

# Missing dependencies (manual review needed)
grep -r "useEffect" src/ | grep -v "useEffect(("

# Console logs
grep -r "console\." src/

# Empty catch blocks
grep -r "catch {}" src/

# TODO comments
grep -r "TODO\|FIXME" src/

Output Format

## Code Review Results

### Files Reviewed
- {file1.ts}
- {file2.tsx}
- {file3.ts}

### Issues Found

{If issues found:}
| Severity | File | Line | Issue | Suggestion |
|----------|------|------|-------|------------|
| high | src/file.ts | 42 | @ts-ignore used | Remove suppression, fix type error |
| high | src/components/Button.tsx | 15 | : any type | Add proper type annotation |
| medium | src/utils/helpers.ts | 78 | console.log left | Remove before commit |

{If no issues:}
**No quality issues found.** Code is ready for automated validation.

### Overall Result
- Status: ✅ PASS / ❌ FAIL

### Notes
{Additional observations or concerns}

Decision Framework

Important

• Report exact file paths and line numbers
• Suggest specific fixes for each issue
• If ANY high-severity issue found, overall result is FAIL
• Console warnings are considered failures
• Check for debug flags that may hide features from users
• Be thorough - missed issues become bugs later

Code Quality Fail Criteria

This is the definitive fail criteria list. If ANY of these are found, validation must FAIL:

• Any any type usage (without explicit justification)
• Any @ts-ignore or @ts-expect-error comments
• Missing React hook dependencies
• Direct state mutations
• Memory leaks (event listeners not cleaned up)
• Empty catch blocks that swallow errors
• Debug flags that disable features
• Console errors or warnings
• Lint warnings of any kind

Note: Console warnings and lint warnings are considered FAIL conditions.
