get_public_card_param_values

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

Without annotations, the description carries full burden but only says 'Get values'. It does not disclose that this is a read-only operation, any authentication requirements (public cards typically need no auth but not stated), or what happens on invalid UUID or param_key. No side effects or limitations are mentioned.

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, which is concise but overly minimal. It lacks important context that would make it more useful, such as parameter details or response format. It earns its place as a basic statement but could be improved.

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 sparse description, the agent has little context about the tool's behavior. It does not explain what 'values' are returned, how the response is structured, or any constraints. This is insufficient for a tool with one complex parameter and no annotations.

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 high (both uuid and param_key have descriptions in the schema), so baseline is 3. The description adds no additional meaning beyond what the schema already provides, so score remains 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 clearly states the tool retrieves values for a specific parameter of a public card, using a specific verb 'Get' and resource 'parameter of a public card'. It distinguishes from siblings like 'get_card_param_values' (non-public) and 'search_public_card_param_values' (search behavior), making its purpose unambiguous.

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?

No guidance is provided on when to use this tool versus alternatives such as 'get_embed_card_param_values' or 'search_public_card_param_values'. The description does not mention that it is for public cards exclusively or any prerequisites like knowing the card's UUID.

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