Single tool 'return' has critical definition gaps. Tool name lacks action verb (should be 'echo' or 'return_text'). Parameter 'text' has null description (violates pattern:tool-description). No output schema documented. No error handling guidance. Tool is trivial (echoes input) and unsuitable for production use. Naming is generic and does not convey intent.

• Add a non-empty description to the 'return' tool explaining what it does and when to use it (target 50-200 chars per baseline).
• Replace null parameter description with explicit text: e.g., 'The text string to echo back to the caller.'
• Rename tool from 'return' to 'echo_text' to start with an action verb and clarify intent.
• Document the output schema explicitly, including field names, types, and what each field contains.
• Add error handling for edge cases (empty string, oversized input) with actionable recovery guidance.
