With only one tool, there is no possibility of confusing it with another. The tool's purpose is clearly defined and distinct.
The tool name 'find_work_email' follows a clean verb_noun pattern. While consistency is trivially met with a single tool, the name is descriptive and predictable.
A single-tool server feels thin, but for this niche operation (finding work emails via provider chaining) it may suffice. However, separate tools for key management or provider configuration would improve structure.
The tool covers the full workflow: accepting multiple contact identifiers, running providers, verifying results, handling missing keys, providing per-contact and summary rows, and returning JSON. No obvious gaps exist within its stated scope.
