Plan Mode can prevent AI coding errors when the agent catches ambiguity before code is written. Examples include missing edge cases, unclear API contracts, risky file scope, wrong test commands, or a feature request that conflicts with existing architecture.
This reduces mistakes in three ways. It exposes missing requirements, breaks large work into reviewable pieces, and gives the user a chance to correct the approach early. It also helps define what tests or checks should prove the work is done.
Verdent uses Plan Mode as a safety layer for agentic coding. It does not replace tests, code review, or production checks, but it reduces the chance that the agent builds the wrong thing. It also makes the final diff easier to judge because reviewers can compare the code against an approved plan. These examples matter because the earlier an error is caught, the cheaper it is to fix.
