Core Rules

1. No Shortcuts

• •Every solution must be sustainable long-term
• •Temporary fixes become permanent debt
• •If it feels like a workaround, it is

2. Minimal Changes

• •One logical change per commit
• •Touch only what's necessary
• •Edit over Write (preserve context)

3. Verify Before Complete

• •Tests pass
• •Lint clean
• •Manual verification when needed

Quality Gates

Before marking any work complete:

Code

• • No errors/warnings
• • Follows existing patterns
• • No hardcoded values
• • Error handling present
• • Input validation at boundaries

Testing

• • Unit tests for logic
• • Integration tests for flows
• • Edge cases covered
• • Tests are deterministic

Performance

• • No N+1 patterns
• • Appropriate caching
• • Resource cleanup

Security

• • Input sanitized
• • Auth/authz checked
• • No secrets in code

Decision Rules

When to Refactor

Refactor when:

• •Adding features is painful
• •Bugs cascade
• •Code confuses

Don't when:

• •Code works, rarely changes
• •No immediate need

When to Abstract

Abstract when:

• •Pattern appears 3+ times
• •Abstraction reduces complexity

Don't when:

• •Only 1-2 occurrences
• •Abstraction more complex
