12 tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Most tools lack descriptions for nested object properties (e.g., 'nodes', 'connections', 'settings' in create_workflow have no field-level guidance). No output schemas documented. Naming is verb-first and clear (list_, get_, create_, update_, delete_, activate_, deactivate_, execute_), but two tools combine concerns: 'create_workflow_and_activate' violates single-responsibility (pattern:tool). Parameter descriptions are minimal (1-2 sentences) and lack format/constraint guidance. Error handling not visible in tool definitions. No evidence of idempotency, pagination, or result limits despite tools like list_workflows_full warning of 'high token usage', suggests unbounded output.

• Document output schemas for all tools. Example: create_workflow should return {id: string, name: string, active: boolean, created_at: string}. This enables agents to chain calls.
• Add field-level descriptions to nested objects. For 'nodes' array, specify: 'Array of workflow node objects, each with id (string), name (string), type (string), position (array of 2 numbers), parameters (object).'
• Split create_workflow_and_activate into two separate tools: create_workflow (returns workflow_id) and activate_workflow (accepts workflow_id). Agents can compose them as needed.
• Add pagination to list_workflows_full: accept limit (1-100, default 20) and offset parameters; return total_count and next_offset. Cap results at 50 items per call.
• Add error recovery guidance: 'If workflow not found, call list_workflows() to discover available IDs.' Include this in get_workflow, update_workflow, delete_workflow descriptions.
