14 tools with consistent naming (verb_noun pattern: get_, list_, create_, start_, stop_). All have descriptions (avg 95 chars, within 10-1024 range). Input schemas present with type definitions and descriptions for all parameters. However, output schemas are NOT documented, responses are inferred from code but not formally declared in tool definitions. Parameter descriptions are adequate but generic (e.g., 'Tag IDs (optional)' lacks context on format/constraints). No enum constraints on workspace_id or other categorical fields. Error handling present but minimal, no recovery guidance or categorization. Security: API key injected via env (correct), but config_root parameter is repeated across all 14 tools, creating friction. Missing: tool annotations (readOnlyHint/destructiveHint), pagination guidance for list tools, and output schema documentation.

• Add output schema documentation to all tools. For each tool, declare the response object structure (fields, types, required vs optional). Example: clockify_get_user should document {user_id: string, email: string, active_workspace_id: string, workspaces: [{id, name}]}.
• Implement pagination for list tools: add limit (default 20, max 100) and offset/cursor parameters. Document max result size in tool descriptions. Return total_count and next_cursor in responses.
• Add tool annotations: mark read-only tools with readOnlyHint=true (get_*, list_*), destructive tools with destructiveHint=true (start_timer, stop_timer, create_time_entry, init, automate, unautomate), and idempotent tools with idempotentHint=true where applicable.
• Refactor config_root handling: store it once per session (via initialize or resource discovery) rather than passing it to every tool. Reduces parameter friction and aligns with stateless request handling.
• Enhance parameter descriptions with format/constraint details. E.g., 'tag_ids: array of UUID strings (e.g., ["tag-123", "tag-456"])' instead of 'Tag IDs (optional)'. Add enum constraints for workspace_id, project_id where applicable.
