Well-curated set of 4 focused tools for URL shortening service. Each tool has clear naming, descriptive purpose, and properly typed input schemas with appropriate required/optional parameters. The tools follow a logical workflow pattern (validate → generate → create → analyze). No auto-generation artifacts detected. Descriptions are detailed and actionable. Minor issues: create_short_url description appears truncated in the provided data, and generate_short_code's utility is somewhat limited since the actual code is generated during URL creation.

• Complete the create_short_url description to clearly document all optional parameters and their constraints
• Consider consolidating generate_short_code into create_short_url as an optional behavior, or remove it entirely if agents should rely on auto-generation
• Add timeout or pagination parameters to get_url_stats for handling large analytics datasets
• Document which characters are allowed/disallowed in the 'alias' parameter beyond 'alphanumeric and hyphens'
• Add return type documentation to tool descriptions (e.g., 'Returns: JSON object with {short_url, created_at, ...}')
