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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does well by declaring this a WRITE OPERATION that changes PCE state and explaining the approval-pause behavior and the no-retry rule. This adds significant value beyond the tool name. It could additionally mention the success return format, but the disclosed behavior is substantial.

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?

The description is two tightly written sentences with no wasted words. The primary purpose is front-loaded, and the behavioral warning follows. It's efficient and well-structured, though slightly below a 5 because it packs the approval-gating note somewhat densely without formatting breaks.

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 create operation with no output schema and no annotations, the description covers the write nature and approval behavior well but doesn't describe what a successful call returns or any prerequisites (e.g., permissions). It's adequate for a straightforward create tool but leaves the agent to infer the response shape.

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 100%, so the baseline is 3. The description adds no parameter-level detail beyond what the schema already documents for name, ip_ranges, fqdn, and description. The schema fully covers parameter meaning, so the description correctly leaves this to the structured data.

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 states a specific verb and resource: 'Create a new IP List in the PCE'. The create/update/delete/get verbs on the sibling tools make the action unambiguous. It doesn't explicitly name sibling differentiators, but 'Create' vs 'update-iplist', 'delete-iplist', and 'get-iplists' is self-evident enough to warrant a 4 rather than a 5.

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 provides useful contextual guidance about the approval gate in clients like Claude Desktop/Code and explicitly warns against retrying while waiting. However, it doesn't state when to use this tool vs alternatives (e.g., when to create a new IP list vs updating an existing one with update-iplist), so usage context is implied rather than explicit.

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