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

No annotations are provided, so the description carries the full burden, and it discloses nothing: no auth requirements, rate limits, caching, or what the 'specifications' payload contains. A noun phrase is not behavioral disclosure.

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 words is not conciseness but under-specification; nothing is front-loaded because there is nothing to front-load. The brevity here costs the agent information rather than saving it effort.

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?

With zero annotations, no output schema, and a two-word description, the definition gives the agent nothing about what comes back, how it differs from the many sibling tank endpoints, or its intended use case. It is inadequate for a tool in such a crowded namespace.

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%: slug is documented with an example (is-7) and region has an enum plus a description, so the schema already does the work. Per the high-coverage baseline, a 3 is appropriate even though the description adds no parameter meaning of its own.

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 phrase 'Tank specifications' merely restates the tool name in prose (slug + specifications) with no verb, scope, or distinguishing detail. It does not separate this tool from siblings like tanks_by_slug, tanks_by_slug_detail, tanks_specifications, or og_tanks_by_slug, which all plausibly return tank data.

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?

There is no when-to-use guidance, no mention of when-not to use it, and no reference to any alternative sibling (e.g. tanks_by_slug_detail or tanks_specifications). The agent must infer the choice purely from the name.

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