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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the description doesn't need to restate safety. It adds genuinely new behavioral context: the response is limited to the selected property and never exposes OAuth credentials or other properties on the Google account, and it explicitly does not mutate integration state. This is real disclosure beyond the annotation envelope.

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 short sentences, front-loaded with the core verb+resource, followed by the return-scope constraint and the exclusion. Every clause carries information; nothing is padding.

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 simple single-parameter read tool with no output schema, the description covers purpose, scope of the response, and what it will not do. It stops short of describing the actual return shape (e.g., a status flag plus property identifier versus an object), so an agent still has minor uncertainty about what it receives.

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?

There is one parameter with 100% schema description coverage; the schema already explains workspaceId and points at list_workspaces for discovery. The description adds no format, range, or resolution detail, so the baseline 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 ('Read whether this workspace has an active verified Google Search Console integration with a selected property'), scoped to a single workspace. It also carves out the boundary against connect/verify and data-query operations, so an agent can separate it from siblings like query_search_console without opening any schema.

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?

Gives explicit negative guidance ('Does not connect or verify an integration'), which tells the agent when this tool is the wrong choice for setup tasks. However, it never names the alternative tools (e.g., query_search_console for actual data, or whatever tool performs verification), so the routing is only half-specified.

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