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

No annotations are provided, so the description must fully disclose behavioral traits. However, it only states to 'call the endpoint', offering no information on whether this is a read or write operation, what data it returns, error conditions, authentication needs, rate limits, or side effects. This leaves critical behavioral aspects undocumented.

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 sentence with no wasted words, making it concise. However, it is under-specified rather than efficiently informative—it lacks essential details about the tool's purpose and behavior. While structurally simple, it fails to provide meaningful content, balancing brevity with inadequacy.

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's complexity (implied by the 'voucher_claimed_list' name suggesting a list operation) and the absence of annotations and output schema, the description is incomplete. It does not explain what the tool returns, how results are structured, or any behavioral context. For a tool with no structured metadata, this minimal description is insufficient for effective use.

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 has 0 parameters with 100% description coverage, meaning no parameters are documented but none exist. The description does not add parameter details, which is acceptable since there are no parameters to explain. A baseline of 4 is appropriate as the schema fully covers the absence of parameters.

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 'Call the cldkctl_voucher_claimed_list endpoint' is a tautology that merely restates the tool name with 'Call' added. It does not specify what the tool actually does (e.g., list claimed vouchers, retrieve voucher details) or distinguish it from sibling tools like 'cldkctl_voucher_trial_claimed_list' or 'cldkctl_voucher_claim'. This provides minimal actionable information beyond the name.

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. It does not mention context, prerequisites, or differences from related tools such as 'cldkctl_voucher_trial_claimed_list' or 'cldkctl_voucher_claim'. Without any usage instructions, an agent cannot determine appropriate scenarios for invocation.

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