Multimodal Function Call Payload Validation Checklist

Role: Senior Multimodal Integration Architect

Context

• Multimodal Model: {{multimodal_model_name}}
• Target Diffusion Endpoint: {{target_diffusion_endpoint}}
• Image Payload Format: {{image_payload_type}}
• Supported Aspect Ratios: {{allowed_aspect_ratios}}
• Max Parameter Token Budget: {{max_token_budget}}
• Fallback Failure Tool: {{error_fallback_tool}}

Task

Generate a rigorous pre-execution audit checklist to ensure {{multimodal_model_name}} correctly structures function call arguments when dispatching image synthesis requests to {{target_diffusion_endpoint}} without payload malformation.

Method

1. Inspect parameter schema bounds for prompt strings, negative prompts, and dimension tuples.
2. Verify {{image_payload_type}} encoding standards and binary transfer mechanisms within the tool arguments.
3. Validate aspect ratio parsing logic against permissible values in {{allowed_aspect_ratios}}.
4. Check token length limits against {{max_token_budget}} to prevent truncated tool arguments.
5. Confirm strict type-checking rules for integer seeds, guidance scale floats, and scheduler enums.
6. Evaluate error interception routing to {{error_fallback_tool}} when generation endpoints reject payloads.
7. Review response parsers for returning generated asset URIs back into the agent context window.

Constraints

• Checklists MUST use categorized checkboxes ([ ]) with verification criteria.
• You MUST NOT approve ambiguous type definitions such as unconstrained string types for numeric fields.
• All checks must specifically address multimodal tool invocation risks.
• Output must focus purely on schema validation, payload safety, and execution boundaries.

Output format

Provide the review as a structured markdown checklist with exactly 4 sections:

1. Argument Schema & Type Validation (4-5 check items)
2. Payload & Encoding Integrity (3-4 check items)
3. Parameter Range & Constraint Verification (3-4 check items)
4. Error Interception & Fallback Routing (3-4 check items)

Self-review

• Are all {{allowed_aspect_ratios}} and {{image_payload_type}} nuances represented?
• Are fallback rules for {{error_fallback_tool}} clearly testable?
• Is every item formatted as a discrete, actionable checkbox?
