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

The description calls this 'a safe job (a backup, cache clear or security scan),' which directly contradicts the destructiveHint=true annotation. It also does not explain permissions, reversibility, or what 'is recorded' means for a destructive-marked operation.

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 first sentence is efficient, but the second sentence is tangled: 'Through Royally: a safe job...' is confusing boilerplate and is not front-loaded. It also introduces a safety claim that conflicts with the annotations.

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?

There is no output schema, and the description does not say whether scan results are returned directly or must be fetched via gp_get_vulnerability_results. Saying the job 'is recorded' hints at asynchronous behavior but does not explain how an agent should retrieve or interpret the results.

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 coverage is 100% and there is only one parameter (site_id), so the schema already documents it fully. The description repeats the demo site URL, which maps to the enum value, but adds no syntax or selection guidance beyond the schema.

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?

States a specific verb and resource: 'Run a vulnerability scan checking for outdated plugins, themes, and security misconfigurations.' It is clear what the tool does, but it does not distinguish itself from sibling security tools like gp_get_vulnerability_results, check_vulnerabilities, or scan_security.

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?

Provides no when-to-use guidance, no alternatives, and no prerequisites. The 'Through Royally' sentence describes execution behavior rather than helping an agent choose between this scan and sibling tools that retrieve or summarize vulnerability data.

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