get_images_stats

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

No annotations are present, so the description must carry the full behavioral burden. The verb 'Get' implies a read-only operation, but nothing is said about the nature of the statistics, authentication needs, or response behavior. This is a bare one-liner that adds little beyond the tool name.

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?

One short, front-loaded sentence with no filler. Every word contributes to identifying the operation and resource, so it earns a high score on conciseness despite being terse.

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?

The tool is simple: one required parameter, no nested objects, and no output schema. Given that simplicity, the description is minimally viable, but it does not explain what statistics are returned or what period/metrics they cover, leaving some ambiguity for an agent selecting and consuming the result.

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 description coverage is 100%, so the account_id parameter is already fully documented in the input schema. The description adds no extra semantic detail about the parameter, but because the schema fully covers it, the baseline of 3 is appropriate.

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 uses a specific verb ('Get') and identifies a specific resource ('Cloudflare Images usage statistics'), making the tool's purpose unambiguous. It does not explicitly contrast with siblings like list_images, but the phrase 'usage statistics' makes the distinction reasonably clear.

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 about when to choose this tool over list_images, get_zone_analytics, or other analytics endpoints. The intended use case is only implied by the name and description, with no exclusions, prerequisites, or alternative routing.

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