What problem this solves

AI coding agents generating large amounts of incorrect or undesirable code before user intervention, leading to significant cleanup time and wasted effort.

Summary

Leverage Claude Code's 'plan mode' to proactively review and approve an agent's proposed approach before it generates any code. This prevents costly rework by catching bad assumptions and unwanted actions at the planning stage.

Why it is useful

This workflow provides a simple, repeatable, and validated method to mitigate a common and costly problem when using AI coding agents: the generation of large amounts of incorrect or undesirable code. By institutionalizing a 'plan mode' review step, users can catch critical errors and bad assumptions early, saving significant time, effort, and resources in debugging and rework. It promotes a disciplined and efficient interaction pattern, enhancing user control and the overall quality of AI-assisted development.

Workflow

1. Initiate a coding task with a Claude Code agent.
2. Allow the agent to generate a detailed plan using its 'plan mode' feature.
3. Carefully read and review the agent's proposed plan.
4. Identify and correct any bad assumptions, undesirable actions (e.g., touching shared configurations), or misinterpretations within the plan.
5. Approve the refined plan, allowing the agent to proceed with code generation based on the validated approach.

Tools / artifacts

• Claude Code
• Plan mode feature

Validation signals

• User's personal experience: 'saved me hours of cleanup.'
• Concrete example: 'it planned to touch a shared config I did not want changed, and I killed that in the plan stage in five seconds.'
• Before/after comparison: contrasts 'sprint off and write two hundred lines' with catching issues 'in five seconds'.

Limitations

• The workflow relies on the user's diligence and expertise in reviewing the plan, without providing specific guidance on how to conduct an effective review.
• Does not offer specific prompting strategies for plan generation or refinement.
