Two focused tools with reasonable naming and schema structure, but incomplete schema definitions (truncated JSON), vague descriptions, and unclear use cases limit effectiveness. Schema completeness issues are critical - both input definitions appear cut off mid-property, preventing proper validation. Description text lacks specificity about when/why to use these tools in agent workflows.

Truncated input schema definitions - both tools have incomplete JSON with properties cut off (instructions array and lineItems object never completed)
Vague descriptions lack context about agent decision-making - descriptions state WHAT tools do but not WHEN agents should use them or what problems they solve
Missing required field documentation - unclear which fields are truly required vs optional (only 'title' explicitly marked required in descriptions)
No error handling or side effect documentation - no mention of validation rules (e.g., image dimensions 500x500), API limits, or failure modes
