kiasumiles_data_version

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

No annotations are provided, so the description bears full responsibility. It accurately describes a read-only operation ('Return') with no side effects, which is transparent enough. However, it could mention that it is a safe, non-destructive call, but the lack of annotations does not lead to contradiction.

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?

A single, succinct sentence that conveys all necessary information without any superfluous words. Every word earns its place.

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 the tool has no parameters and an output schema exists, the description fully covers what the agent needs to know: the tool returns the current version of hosted card and merchant data. No additional context is required.

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 tool has zero parameters and the schema coverage is 100%. The description adds meaning by specifying that the version pertains to 'hosted card and merchant data', which provides useful context beyond the empty schema. Baseline for 0 parameters is 4, and the description meets it.

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 uses a specific verb ('Return') and names the exact resource ('current hosted card and merchant data version'), making the purpose crystal clear. It also naturally distinguishes from sibling tools like 'kiasumiles_list_cards' or 'kiasumiles_lookup'.

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 needing the data version, but provides no explicit guidance on when to use this tool versus alternatives, nor any when-not-to-use scenarios. Given the tool's simplicity, this is acceptable but not exemplary.

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