生産性とワークフロー

Enforces a structured problem definition phase before code implementation to eliminate understanding debt and logic errors.

The define skill (an alias for /tf:0) serves as the foundational step of the Think First methodology within Claude Code. It focuses on the 'Phase 0' discovery process, ensuring that the AI fully understands the problem space, requirements, and existing architecture before a single line of code is modified. By utilizing file reading, bash execution, and interactive questioning, this skill prevents 'understanding debt'—the technical friction caused by misinterpreting project goals—resulting in more accurate, higher-quality implementations.
