services_networks_ipv6_get_list

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered elsewhere. The description adds only the REST path, which restates the per-service scoping implied by the name; it says nothing about return shape, empty results, pagination, or auth/scope requirements.

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?

It is short and the endpoint line is front-loaded, but the first line is pure redundancy with the tool name, so only half the content earns its place. No markdown structure or separation of intent from mechanics.

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 read-only list tool with one param and no output schema, the definition still leaves core questions open: what the response items represent, whether the list can be empty, and how it differs from the IPv4 sibling. The annotations cover safety but not the domain semantics an agent needs to choose this tool confidently.

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 description coverage is 0% for the single required parameter, so the description carries the burden. The path template shows serviceId is a path segment identifying the service, which is minimal added meaning, but it gives no hint about valid values, how to obtain a serviceId, or what happens with a nonexistent/invalid id.

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?

The description is essentially the snake_case name re-spelled in words plus the raw HTTP path 'GET /services/{serviceId}/networks/ipv6'. It conveys that this is a read of IPv6 networks for a service, but adds no framing beyond the name and never says what an 'ipv6 network' resource contains or why one would list it.

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?

There is no when-to-use guidance, no prerequisites (e.g. must the service have IPv6 enabled?), and no mention of the obvious sibling services_networks_ipv4_get_list. The agent must infer usage entirely from the name.

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