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

No annotations are provided, so the description carries the full behavioral burden, but it says nothing about what is returned, whether the operation is read-only, what permissions are needed, or how loadout data is scoped. The two-word description leaves behavior entirely undisclosed.

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 only two words and contains no structural information. Its brevity is under-specification rather than useful conciseness, since no actionable context is front-loaded.

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 four-parameter tool with required region and slug, no annotations, and no output schema, the description is far too thin. It does not explain the purpose, usage context, or return behavior, leaving the agent with insufficient information to invoke it correctly.

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 coverage is 75%, and the schema itself documents mode, slug, and region well, so the baseline is adequate. The description adds no meaning beyond the schema, and the language parameter remains undocumented, but the schema does most of the work.

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?

"Tank loadouts" essentially restates the tool name and does not specify whether it lists preset loadouts, returns equipment recommendations, or provides loadout-related stats. It lacks a clear verb and scope, so the agent cannot confidently distinguish it from related tank endpoints.

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 gives no indication of when to use this tool rather than siblings such as tanks_by_slug_detail, tanks_by_slug_specifications, or players_by_nickname_tanks_by_slug_loadout. There are no exclusions, prerequisites, or alternative-routing guidance.

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