Add a useful search filter

Choose the most effective prompt for these specific constraints. There is no universally best wording.

THE TASK

A task list already renders correctly. Add case-insensitive title filtering. An empty query must preserve all tasks and their order. No new dependencies. The repository has not been inspected.

Which prompt best fits the task?Prompt AAdd a search box and make filtering feel polished. Keep the implementation small and report when it works.Prompt BInspect the existing list, repository instructions and test scripts. Add case-insensitive title filtering; empty input preserves order. Reuse the UI, add no dependencies, verify both cases and review the diff.Prompt CImplement case-insensitive filtering in src/search.ts, run npm test and summarize the change. Do not change unrelated files.Prompt DFirst design a reusable search framework with fuzzy matching and indexed caching. Compare three libraries, document performance targets, create a migration plan and add extensive unit tests. Then implement title filtering as the first consumer, preserving the existing component styling and documenting the new architecture for future teams.
