The parameter explanations are **detailed yet clear**, including valid options (e.g., `mode`, `conflict_strategy`) and edge cases (e.g., `dry_run`). The **examples** are realistic and demonstrate key use cases. Minor improvements could include fixing a typo in the second example (`mirror` missing closing quote) and explicitly noting that `SyncResult` is a placeholder for a real implementation. Overall, this is **production-ready documentation** for a developer."
