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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering the safety profile. The description adds the included stat categories but does not disclose potential caveats such as data freshness, permissions, or output size. This is acceptable but not exceptional given annotation coverage.

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 a single front-loaded sentence that wastes no words and efficiently lists all relevant output categories. It is easy to scan and directly supports tool selection.

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?

For a one-parameter read-only tool with annotations covering safety, the description is mostly complete: it states the purpose and enumerates expected results. The only gap is lacking any note on return format or how website_id relates to other tools like list_websites, but this is minor given the tool's simplicity.

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 0%, with one integer parameter website_id. The description only says 'for a website' and does not explain that website_id is the website identifier, how to obtain it, or any format expectations. This adds minimal value beyond the schema's 'Website Id' title.

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 resource ('content stats') and enumerates the exact fields returned: total articles, keywords tracked, published posts, and SEO autopilot status. This clearly distinguishes it from sibling tools without requiring schema inspection.

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 explicit when-to-use guidance or comparison with alternatives is provided. While siblings like list_websites and list_articles have distinct names, the description does not clarify that this tool returns aggregate stats rather than raw lists, leaving usage context to inference.

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