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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=false, so safety is covered. The description adds the required provider value but does not explain what returning the URL accomplishes (does it initiate OAuth, persist a connection, expire?), leaving behavioral intent thin for a non-read-only tool.

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 crisp, front-loaded sentences with no filler. It is lean but arguably terse for the tool's complexity, which slightly caps it below a 5.

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, so return-format explanation isn't required, but the returned URL is the entire payload and the description never clarifies its purpose or lifecycle. Combined with the undocumented nested input, the definition is adequate but leaves meaningful gaps.

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 75%, but the nested 'input' object is undocumented (additionalProperties only). The description compensates by telling the agent to set 'provider' to gam or adsense inside that object, adding real meaning 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 ('Return the GAM or AdSense authorization URL'), so the agent knows this yields an auth URL for a backup provider. It does not, however, distinguish this from adjacent siblings like map_sulvo_placement_backup or import_sulvo_backup_units.

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?

The description scopes the tool to GAM/AdSense backup-provider connection via the required 'provider' value, which implies when to use it. It gives no explicit when-not guidance or alternatives among the many sibling tools.

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