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

With no annotations, the description provides some behavioral context by listing endpoints and their associated cost ($0.10 each), but it does not disclose side effects, authentication requirements, rate limits, or data freshness. The 'AI-synthesized' note adds transparency about data origin.

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 well-structured with a clear opening line, coverage note, and a bulleted list of endpoints with brief descriptions. It is front-loaded with the core purpose. Minor verbosity exists but is justified by the need to document multiple endpoints.

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 (7 parameters, 8 actions) and no output schema, the description adequately covers endpoints but does not explain how parameters like 'item', 'grade', or 'service' interact with each action. Agents may need additional inference to correctly construct calls.

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 schema covers 100% of parameters with descriptions, but the long-form description adds significant value by explaining each endpoint's purpose (e.g., 'Current market value by grade/condition' for value). This helps the agent understand how to use the action parameter and related parameters in context.

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 identifies the tool as a collectibles market intelligence API covering multiple collectible categories. It lists specific endpoints which clarify the variety of functions, though the broad scope (valuations, authentication, selling guides) somewhat dilutes a singular verb+resource focus.

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 for collectibles-related queries and differentiates from sibling 'pulse' tools by specifying collectibles. However, it lacks explicit guidance on when to use this tool versus alternatives within the sibling set, nor does it state when not to use it.

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