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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered elsewhere. The description adds the required read scope, which is genuine behavioral context, and implies the response enumerates platforms, but says nothing about what happens when no account is connected or what error surface a missing scope produces.

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 short sentence with the purpose front-loaded and no filler; the scope caveat is attached compactly in parentheses. It is lean to the point of terse, but every word earns its place.

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 zero-parameter read tool with annotations covering safety and no output schema, the description supplies the two things an agent needs: what is checked and the auth scope required. Only edge-case behavior for unconnected accounts or insufficient scope is left unstated.

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?

The tool takes zero parameters, so the schema baseline applies and there is nothing for the description to disambiguate. The description correctly implies no inputs are needed.

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?

Uses a specific verb ('check') with a specific resource ('which platforms have a connected dropspace official account'), so an agent can tell this is a connection-status read rather than a list/launch/analytics tool. It stops short of naming a sibling it must not be confused with, such as list_connections.

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 parenthetical '(requires read scope)' gives a real prerequisite for calling it, which is useful selection context. There is no explicit statement of when to prefer this over the similarly-scoped list_connections or when it should not be used.

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