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

Adds real behavioral context beyond annotations: the tool not only checks connectivity but 'update[s] the integration's health status' — a mutating side effect consistent with readOnlyHint=false and idempotentHint=true. This disclosure is valuable since annotations alone would not reveal the health-status update.

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?

Three sentences, front-loaded with the core purpose, then returns, then parameter guidance and preconditions. No filler; each sentence adds distinct information. Could be marginally tighter but is appropriately sized.

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?

Complete for a 1-optional-param tool: covers purpose, side effect, param semantics, and prerequisites. Since an output schema exists, the return-value shape is already covered and need not be restated. No material gaps for correct invocation.

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?

With 0% schema description coverage, the description carries the full burden for integrationId and compensates well: it explains the condition for passing it (multiple connected blogs) and its fallback behavior (single blog used otherwise). Adds meaning the schema's bare string type cannot convey.

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 ('Test connectivity to the team's connected WordPress blog') plus the side-effect of updating health status. Clearly distinguishes from all 32 siblings — none of which are connectivity/diagnostic tools — so an agent can tell this apart without opening schemas.

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?

Explains when to pass integrationId ('when more than one blog is connected; otherwise the single connected blog is used') and notes the prerequisite ('a blog must be connected first' / Business/Teams feature). Does not explicitly name excluded alternatives, but the diagnostic purpose and preconditions make usage context clear.

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