compose_images

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided; description offers no behavioral details such as output format, side effects, or required permissions. Only restates purpose.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, efficient but too minimal. Could be expanded with key behavioral info without losing conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Lacks output schema and annotations. Does not explain return value or behavior. Severely incomplete for a tool with 3 parameters.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Description adds minimal value to schema: 'multiple input images' is redundant with schema. The prompt description is less informative than the schema's detailed description. Missing schema coverage for images items not compensated.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (compose) and resource (new image), using multiple input images and a guiding prompt. It distinguishes from sibling tools: edit_image edits existing, generate_image creates from scratch, style_transfer applies style.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. Lacks explicit context or when-not-to-use conditions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
