osint_mac_vendor_lookup

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

No annotations are provided, so the description carries full burden. It mentions 'online' but does not disclose whether network access is required, rate limits, or authentication needs. It also does not describe error behavior or side effects.

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 short and front-loaded with purpose. However, it includes the unnecessary 'Menu ID: mac_vendor' line. Overall, it is concise but could be structured better by removing redundant phrases.

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 tool with no parameters and no output schema, the description should provide more context on how to invoke it (e.g., what to input) and what output to expect. It mentions 'detailed analysis' but does not specify the return format. The guidance to use describe_tool shifts responsibility, but the description itself is incomplete.

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 input schema defines no parameters but allows additional properties (additionalProperties: true). The description adds no clarification on expected input format or that the tool likely requires a MAC address as an argument. This omission could confuse an agent.

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's purpose: lookup MAC address vendors and manufacturers using an OUI database. It specifies the resource (MAC address) and the action (vendor lookup), which distinguishes it from other tools in the list.

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 when to use the tool (for MAC vendor lookup) but does not explicitly state when not to use it or provide alternatives. It lacks guidance on prerequisites or decision criteria.

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