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

Since no annotations are provided, this description provides exceptional behavioral context: it explains the 'AI Studio run' resource model, credit consumption rules, file deletion policies post-processing, and auditable retention methods.

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?

The description is extremely dense, blending functional usage with lengthy business and pricing policy details. While comprehensive, this reduces the conciseness of the core tool definition.

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?

Given the complexity of AI resource management and the lack of annotations/output schemas, the description is highly complete, covering the entire lifecycle from generation to credit usage and data retention.

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?

The schema coverage is 100% (zero parameters), so the description doesn't need to add semantic meaning to inputs. However, it adds conceptual meaning by instructing the user to provide a description, style, and size.

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 explicitly states the tool is an 'AI Image Generator' and defines its core workflow: describing the image, choosing style/size, and generating a draft.

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?

While the purpose is clear, it doesn't explicitly state when *not* to use the tool compared to the extensive list of sibling tools (e.g., if the image needs photo restoration vs generation).

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