create-iplist

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 but offers minimal information. It states the tool creates something but doesn't describe what happens after creation (e.g., whether the IP list is immediately active, if there are rate limits, or if it requires specific permissions). For a mutation tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 a single, efficient sentence that directly states the tool's purpose without unnecessary words. It is appropriately sized and front-loaded, with zero wasted text. Every part of the sentence earns its place by conveying essential information.

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?

Given the tool's complexity (a mutation operation with 4 parameters) and the lack of annotations and output schema, the description is incomplete. It doesn't address behavioral aspects like permissions, side effects, or response format, which are critical for an agent to use the tool correctly. The high schema coverage helps with parameters but doesn't compensate for the overall gaps.

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 description adds no parameter information beyond what the input schema provides. Since schema description coverage is 100%, the baseline score is 3. The schema fully documents all parameters (name, description, ip_ranges, fqdn) with clear descriptions, so the description doesn't need to compensate but also doesn't add extra context like examples or constraints.

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 clearly states the action ('Create') and resource ('new IP List in the PCE'), making the purpose immediately understandable. It distinguishes from sibling tools like 'update-iplist' and 'delete-iplist' by specifying creation rather than modification or deletion. However, it doesn't explicitly differentiate from other creation tools like 'create-label' or 'create-ruleset' beyond the resource type.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., authentication, permissions), when not to use it, or how it relates to sibling tools like 'update-iplist' or 'get-iplists'. The agent must infer usage from the tool name and context alone.

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