TL;DR · WeSearch summary

The article describes an incident where an AI agent generated redundant code because it failed to recognize existing functionality in a codebase. The author emphasizes the importance of reviewing existing code before creating new solutions, calling this essential step 'Phase 0'. Skipping this step led to a full day of work being discarded, highlighting the cost of overlooking simple verification processes.

Key facts

▪An AI agent generated a duplicate component because it did not review existing code in the repository.
▪The author identifies a 'Phase 0' step—spending two minutes searching for existing patterns—as a critical prerequisite before writing new code.
▪Failing to perform this basic check resulted in a full day's work being thrown away due to redundant and unnecessary code.
▪The existing solution was located nearby in the codebase and had a clear, descriptive file name.
▪The incident underscores that the responsibility for code duplication lies with the human developer, not the AI agent, when proper review steps are skipped.
