Single tool 'story_query' has a comprehensive description (250+ chars) and well-defined input schema with 9 parameters, each with type and description. Tool annotations (ReadOnlyHint, DestructiveHint, IdempotentHint, OpenWorldHint) are present and correct. However, output schema is not formally documented in the tool definition, the response structure is inferred from the Run function's JSON marshaling. Parameter descriptions are adequate but lack format constraints (e.g., 'month' should specify 1-12 range explicitly in description, not just in parenthetical). No error recovery guidance in description. Naming follows verb_noun pattern correctly.

• Add formal output schema documentation to the tool definition. Document the response structure: {total: int, offset: int, limit: int, results: [{hash, title, authors, feed_id, date (ISO 8601), user_tags, permalink}]}.
• Replace example values in parameter descriptions with enum constraints or format declarations. E.g., for 'tag', define valid tags as an enum or state 'user-defined tag string' without examples.
• Add explicit min/max constraints to numeric parameters in descriptions. E.g., 'month: integer, 1-12 (requires year parameter)' and 'limit: integer, 1-1000 (default 100)'.
• Include error recovery guidance in the tool description. E.g., 'If the story store is unavailable, the server may not have a connected client. Retry after verifying the client connection.'
• Add a has_more or next_offset field to the response to signal whether additional results exist, enabling agents to paginate intelligently without guessing.
