calculate_wildcard_mask

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

With no annotations, the description must fully disclose behavior. It states it generates details, but does not specify what details are returned, if there are any constraints (e.g., valid CIDR), or side effects. This is insufficient for a safe selection.

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 concise sentence, front-loaded with the purpose. No wasted words.

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 no output schema and zero annotations, the description is too brief. It does not explain output format, constraints, or the optional parameter's effect. Sibling tools exist but are not referenced to aid selection.

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%, so the description should compensate. The parameters ip_address and cidr_prefix are self-explanatory, but include_ospf_command (default true) is ambiguous—it does not explain what including the OSPF command means. No added value beyond parameter names.

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 tool generates OSPF wildcard mask details for a subnet, which distinguishes it from sibling tools like calculate_subnet (general subnet info), calculate_subnet_from_mask (subnet from mask), get_nth_usable_ip (specific IP), and validate_ip_in_subnet (membership check).

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 implies usage when OSPF wildcard mask is needed, but provides no explicit guidance on when to use this tool versus alternatives, nor any prerequisites or conditions.

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