horizon_torn_getMyFactionStats

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

No annotations are provided, so the description carries full burden for behavioral disclosure. It only states the purpose but does not explain authentication requirements, potential errors, rate limits, or what happens if the user has no faction. The description is minimal and fails to disclose important behavioral traits.

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 short sentence that is efficient and to the point. However, it could be slightly more structured or include additional context without becoming verbose.

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 no annotations, the description is too sparse. It does not explain what 'challenges stats' includes, the return format, caching behavior, or edge cases. For a tool with three optional parameters, the description lacks completeness.

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%, meaning all three parameters (key, comment, timestamp) are described in the schema. The description adds no additional meaning beyond what the schema provides, so it meets the baseline of 3.

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 'Get your faction's challenges stats' clearly states the verb 'Get' and the resource 'your faction's challenges stats'. It distinguishes this tool from sibling tools like horizon_torn_getMyFactionBasicInformation or horizon_torn_getMyFactionChain, which retrieve different aspects of faction 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?

The description provides no guidance on when to use this tool versus alternatives, such as other faction-related tools among the siblings. There is no mention of prerequisites, limitations, or scenarios that would make this tool preferred.

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