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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds genuinely new behavioral context: the payload originates from a turbocheck report refreshed once daily, and a timestamp is included in the response, so the agent knows results can lag behind very recent changes.

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?

Two tight sentences: the capability and its returned facets come first, followed by the single caveat that governs interpretation of the result. Nothing is redundant or padded.

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 single-parameter read-only lookup with safety fully covered by annotations and no output schema, the definition supplies what is needed: what is returned and how fresh it is. It leaves only sibling routing unaddressed, which is a usage-guideline gap rather than a completeness one.

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% and there is only one parameter, whose format ('example.com') is already documented in the schema. The description adds no parameter-level meaning beyond that, so the baseline of 3 applies.

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 ('WordPress-Status einer Domain abrufen') and enumerates the returned facets (Version, Updates, Cache, Sicherheits-Flags), which lets an agent distinguish it from the security/integrity siblings by scope. It never names a sibling it is not, so it stops short of full differentiation.

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 when-to-use, when-not-to-use, or alternative routing is given, despite many closely related WordPress siblings (check_wordpress_integrity, get_wordpress_hardening, get_wordpress_sites, scan_wordpress_vulnerabilities). The freshness caveat is about data quality, not about choosing this tool over another.

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