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

With no annotations, the description carries the full burden of behavioral disclosure. It only says 'Get' without indicating whether this is a safe read, whether it generates or retrieves a stored image, or any auth/rate-limit implications. This is minimal and insufficient for a full understanding.

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 concise (six words) and front-loaded, avoiding any wasted words. While it could include more context without bloat, its efficient structure earns a high score.

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?

Without an output schema or annotations, the description should explain the return format and surrounding context. It merely says 'image URL' without describing snapshot semantics, how URLs are generated, or any prerequisites. This leaves notable gaps for a complete understanding.

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?

Schema descriptions cover all parameters (100%), including 'serp_id' as 'SERP snapshot ID' and generic passthrough fields. The description adds no extra meaning beyond what the schema provides, but the baseline 3 applies because the schema already documents each parameter.

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 specific action: retrieving the image URL for a SERP snapshot. The verb 'Get' and the resource 'SERP snapshot image URL' precisely define the tool's output and distinguish it from siblings that list SERPs or provide metrics.

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 is provided on when to use this tool vs. alternatives. It lacks prerequisites (e.g., needing an existing snapshot ID) and does not mention any exclusions or related tools. The usage context is entirely unaddressed.

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