Get network appliance capabilities

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

Annotations already declare readOnly/idempotent/non-destructive, and the description adds real value beyond them: prices and tier availability come from the backend and are never hardcoded, ownership/feature/2FA lock enforcement happens server-side, and a specific permission scope is required. It stops short of describing response shape or any limits, so not a 5.

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?

Front-loads what is read in the first sentence, then layers permissions and enforcement. All three sentences carry information, though the permissions clause is dense and could be split or trimmed slightly.

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 no output schema, the description is largely sufficient: it lists the categories of data returned and explains the auth/enforcement model. It could go further by sketching the return shape or noting the absence of pagination/filtering, but nothing critical is missing.

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 and the description correctly adds no parameter detail; per the rubric, a 0-parameter tool gets a baseline of 4. Nothing is missing or contradictory.

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 ('Read') and enumerates concrete resources: load balancer providers/tiers, public qualification, VPN capabilities (technologies, ipsec_vendors), and quota. This clearly signals it is a capability-discovery tool for network appliances, though it never distinguishes itself from near-neighbors like get_networking_capabilities or get_networking_features.

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 permission prerequisites (networking:read vs networking:manage, and that full/read defaults don't grant networking) give useful context for calling it, but there is no explicit when-to-use guidance relative to the many sibling capability/feature tools. Usage is implied by the returned data rather than stated.

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