Daily Coding Checklist

A minimal coding quality assurance checklist ensuring every code modification follows best practices.

When to Use

Use this skill for:

• Implementing new features
• Adding code or modifying existing code
• User requests like "write a...", "implement...", "add...", or "modify..."
• Any coding task that involves Edit or Write tools

When Not to Use

Do not use this skill for:

• Pure reading or understanding tasks with no modification intent
• Work already covered by specialized skills such as `bug-detective`, `architecture-design`, or `verification-loop`
• Configuration-only changes
• Documentation-only writing

Core Checklist

Before Starting

• [ ] **Read before modify** - Must read target file with Read tool before making changes
• [ ] **Understand context** - Confirm understanding of existing code logic and design intent

During Coding

• [ ] **Minimal changes** - Only change what's necessary, no over-engineering, no unrelated features
• [ ] **Type safety** - Add type hints for Python, avoid `any` in TypeScript
• [ ] **Security check** - Avoid command injection, XSS, SQL injection vulnerabilities

After Completion

• [ ] **Verify execution** - Ensure code runs correctly with no syntax errors
• [ ] **Clean up** - Remove print/console.log debug statements and temporary files
• [ ] **Brief summary** - Inform user what was changed and the scope of impact

Quick Reference

Common Mistakes to Avoid

# ❌ Don't
def process(data=[]):  # Mutable default argument
    pass

# ✅ Should
def process(data: list | None = None):
    data = data or []

# ❌ Don't
except:  # Bare except
    pass

# ✅ Should
except ValueError as e:
    logger.error(f"Processing failed: {e}")
    raise

Security Check Points

• User input must be validated/escaped
• Use pathlib for file paths, avoid path traversal
• Never hardcode sensitive info (API keys, passwords)
