TDD Green Phase

Implement the smallest correct behavior for an agreed failing test while preserving existing requirements, security boundaries and interfaces. Read the bundled playbook as illustrative material, not an executable tool.

Use this skill when

• Moving from red to green in a TDD cycle
• Implementing minimal behavior to satisfy tests
• You want to keep implementation intentionally simple

Do not use this skill when

• You are refactoring for design or performance
• Tests are already passing and you need new requirements
• You need a full architectural redesign
