When Plan Mode Was No Longer Enough

Описание и применение

Использование ExecPlan с этапами позволило уменьшить объём кода, генерируемого AI, и улучшить контроль над процессом ревью, делая его более управляемым и прозрачным.

Задача

Codex CLI’s Plan Mode produced large code blocks that overwhelmed the developer’s review process, creating a bottleneck in understanding and validating the generated code.

Результат

Implementing ExecPlans with milestone-based execution reduced the review burden, improved the developer’s ability to validate and refactor code, and produced a living document that captured decisions and lessons learned.

Рабочий процесс

• 1. Define a high-level ExecPlan with purpose, scope, milestones, and validation strategy.
• 2. Ask Codex to implement the first milestone.
• 3. Review the generated code, refactor if needed, and run focused validation tests.
• 4. Update the ExecPlan with lessons learned and decisions made.
• 5. Repeat steps 2‑4 for subsequent milestones until the feature is complete.
• 6. Finalize documentation and formatting.
• 7. Archive the ExecPlan as a record of the implementation.

Доказательства

After a large implementation, I would receive a substantial set of changes that I still needed to understand, review, refactor, and validate.

Источник

Instead of asking Codex to execute the entire plan, I started asking it to implement one milestone at a time.
