Single tool 'dynamic_workflow_tools' has critical definition gaps. Tool name lacks action verb (should be 'run_workflow' or 'execute_workflow'). Description is 200+ chars but reads as implementation detail rather than LLM-facing guidance, it explains the internal mechanism (filename sanitization, JSON Schema derivation) instead of WHAT the tool does and WHEN to use it. Input schema is declared as 'dynamically generated' with no visible concrete schema in source, only a generic description. No output schema documented. No error handling guidance. Tool definition appears inferred from nanoodle library integration rather than explicitly registered with MCP schema. Violates pattern:tool (verb naming, clear description), pattern:tool-description (actionable guidance), and pattern:response-shaper (output structure).

• Rename tool to 'run_workflow' or 'execute_workflow' to start with action verb and signal intent.
• Rewrite description for LLM clarity: 'Execute a saved nanoodle workflow graph. Accepts media inputs (images, audio, video) as file paths or URLs. Returns workflow output and estimated cost. Use this to run AI tasks like image generation, video synthesis, or text processing defined in your workflow files.'
• Document concrete input schema with parameter types, descriptions, and constraints. Example: { type: 'object', properties: { workflow_name: { type: 'string', description: 'Name of the workflow file (without .json)' }, image_input: { type: 'string', description: 'File path or URL to input image' } }, required: ['workflow_name'] }
• Document output schema: { type: 'object', properties: { success: { type: 'boolean' }, result: { type: 'object', description: 'Workflow output (structure depends on workflow definition)' }, cost_nano: { type: 'number', description: 'Estimated cost in Nano currency' }, error: { type: 'string', description: 'Error message if execution failed' } } }
• Add error handling guidance in description: 'If workflow fails, check that the workflow file exists and all required inputs are provided. Media files must be readable or valid URLs. API errors indicate NanoGPT service issues, retry after a delay.'
