VPS_createNewFirewallV1

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

With no annotations, the description must disclose behavioral traits. It only says 'Create a new firewall' without stating whether creation is idempotent, if there are limits on number of firewalls, or what happens if a firewall with the same name exists. This is insufficient for a mutation tool.

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?

Two sentences are brief but could be improved by adding more detail without excessive verbosity. The current structure is adequate but not optimally informative.

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 creation tool with one parameter and no output schema, the description covers the basic purpose. However, it lacks context on what the created firewall looks like, how to interact with it later, or any prerequisites (e.g., existing VPS). It is minimally complete.

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 only parameter 'name' is described in the schema as 'name parameter', and the tool description adds no additional meaning. It does not clarify naming conventions, uniqueness constraints, or character limits, thus failing to add value beyond the schema.

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 'Create a new firewall' which is a specific verb and resource. It distinguishes itself from sibling firewall tools like VPS_createFirewallRule and VPS_deleteFirewall by focusing on creating the firewall itself, not rules.

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 says 'Use this endpoint to set up new firewall configurations for VPS security' but does not specify when to prefer this over other firewall tools (e.g., VPS_activateFirewallV1). No excluded contexts or alternatives are mentioned.

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