Get networking topology

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds real value beyond them: the required networking:read/networking:manage scopes that defaults do not grant, plus backend-enforced ownership, feature availability and service 2FA locks. These are auth/authorization behaviors the annotations do not convey.

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 purpose followed by the optional parameter and then the permission/enforcement caveats. Dense but every clause adds information; no filler. Slightly packed, which keeps it from 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?

For a read-only topology endpoint with an output schema absent, the description covers purpose, the lone parameter and the permission model an agent must satisfy before calling. What is missing is any indication of the shape of the returned topology, but safety annotations and the low complexity keep this adequate.

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 schema documents the single 'metrics' parameter only via its const value with 0% description coverage. The description compensates by explaining that metrics=current requests measured traffic, giving the agent the semantic meaning of the lone parameter that the schema alone does not provide.

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 the account topology with network-scoped identities.' An agent can tell it is a read of the networking topology, but the description does not distinguish it from close siblings like get_networking_overview or get_networking_features, which share the same get_*networking* naming space.

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 hard prerequisite (explicit networking:read for reads, networking:manage for changes, and that full/read defaults do not grant networking), which is genuinely useful. However, it never says when to choose this tool over get_networking_overview or the other networking readers, so usage is only implied.

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