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

With no annotations, the description carries the full burden of behavioral disclosure, but it only provides a noun phrase. It doesn't say what happens with q, whether it's a lookup or search, what the output looks like, or any limitations.

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, but under-specified to the point of being uninformative. This is not effective conciseness; a sentence with a verb and parameter explanation would earn 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?

Even with an output schema present, the tool needs at least an explicit action and parameter meaning. With one optional parameter and many sibling research-lookup tools, the definition doesn't provide enough context for correct usage.

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 0% and the description never mentions the q parameter. The agent must guess that q is a search query or ORCID iD from the ID format hint, which is insufficient for correct invocation.

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 (ORCID researcher record) and the ID format (0000-000X-…), but lacks a verb and doesn't state whether this tool searches, resolves, or retrieves a record. It does not differentiate it from orcidworks or other researcher-lookup siblings.

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 given on when to use this tool versus alternatives like orcidworks, crossrefauthor, or openalexauthor. There is no mention of exclusions, prerequisites, or conditions that would route an agent to this tool.

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