Why detailed PLAN.md files can quietly break vibe coding
mark_k · x · 2026-07-21
The author argues against blindly using elaborate PLAN.md files for vibe coding.
- Overly detailed plans can lock in wrong assumptions, bad architecture, or the wrong interpretation of the task.
- Once the AI is told to follow the plan, it may keep executing it instead of re-evaluating whether the plan itself is wrong.
- The takeaway: planning is still useful, but it should capture goals, constraints, and major steps—not every implementation detail.
- Treat the plan as a working hypothesis, not scripture.
