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

No annotations are provided, so the description carries the disclosure burden. It does disclose the return contents (notes, price, links) and that it returns a single entry, which is useful. However, it says nothing about read-only guarantees, error behavior, authentication, or other potentially relevant 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 short and front-loaded, but its brevity verges on under-specification. The alias note and the fields list could be valuable, yet the absence of action and parameter guidance makes it concise more due to scarcity than intentional efficiency.

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?

With no output schema, no annotations, and only a single undocumented required parameter, the description fails to provide the minimal context needed. It briefly explains what came out of the entry but does not cover the required `id`, optional return details, or API behavior, so it is not complete for a real agent invocation.

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 has one required parameter, `id`, with no description (0% coverage), and the tool description never mentions it. An agent cannot infer what the ID represents, its format, or how to obtain it, which is a critical gap.

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 identifies the resource (PCC) and indicates it returns a single entry with notes, price, and links, which distinguishes it from search siblings. However, it never states an explicit verb like 'get' or 'retrieve' and 'PCC' plus the retired alias note make the purpose vague and reliant on the tool's 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?

There is no explicit guidance on when to use this tool versus the many sibling tools. The singular 'one entry' only implies a get-instead-of-search use case, but no alternative or exclusion is stated.

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