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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds real value beyond that by describing the content returned — the categories of IDs and the exact tags emitted — which is meaningful since there is no output schema. It does not cover auth requirements or result shape in detail.

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 compact, front-loaded sentence that states scope first and the usage cue last. No filler, though the phrasing is slightly convoluted and could be tighter.

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 read-only, single-parameter status tool with no output schema, the description conveys the return content reasonably well but leaves the 'site' parameter entirely unspecified and gives no sense of output structure. Adequate but with a clear hole for a tool whose only input is undocumented.

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 0% and the single required parameter 'site' has no description anywhere. The description does not compensate by indicating whether 'site' is a name, ID, URL, or slug, so an agent must guess the identifier format. This is the definition's clearest gap.

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 names a specific resource — the tracking/verification IDs and emitted tags present on a site — and enumerates the scope (Analytics, Tag Manager, Google Ads, Search Console, one Ads conversion). It reads a bit awkwardly ('Which ... the Agency MCP Bridge is printing'), but an agent can tell what it retrieves and can distinguish it from the install sibling via 'before installing anything'. It stops short of naming wp_install_tracking explicitly.

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?

It gives a clear use context: read this before installing anything, which directly implies the companion wp_install_tracking alternative and the sequencing between them. There are no explicit exclusions, so it does not reach the top of the scale, but the when-to-use signal is unambiguous.

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