When Plan Mode Was No Longer Enough

说明与用途

采用带有里程碑的 ExecPlan，减少了 AI 生成代码的审查负担，提升了开发过程的可控性和决策记录的透明度。

问题

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.

结果

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.

工作流

• 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.

证据

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

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