# Guidance

**Purpose**\
Use this template to thoroughly evaluate code implementations after they pass
testing. Focus on **adherence** to the specification, code quality,
maintainability, security, performance, and consistency with the project style.

**When to Use**

- After the Tester confirms all tests pass.
- Before merging to the main branch or final integration.

**Best Practices**

- Provide clear, constructive feedback with examples.
- Separate issues by severity (critical vs. minor).
- Commend positive aspects too, fostering a healthy code culture.
