describe_author

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

With no annotations, the description carries the full behavioral burden. 'Get' implies a non-mutating read and it does disclose the content categories returned, but it says nothing about permissions, whether this reflects live vs cached schema, or cost/latency. Adequate but thin for an annotation-free tool.

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?

A single front-loaded sentence with no filler; the resource and returned content come first. It is efficient, though it could have spent one more clause routing the agent away from the get_/list_ siblings.

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?

Complexity is low (no params, no output schema), and the description does state what comes back (fields, relationships, admin config), so an agent knows the shape of the response. The only meaningful gap is the absence of sibling differentiation against get_author/list_author.

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 tool takes zero parameters, so the baseline is 4. There is nothing for the description to clarify beyond what the empty schema already communicates.

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?

States a specific verb ('Get') and resource ('metadata about the Author model') and enumerates the payload (field definitions, relationships, admin configuration). It is clear on its own, but it never distinguishes itself from sibling metadata tools such as describe_article/describe_mcptoken or from the data-fetching get_author/list_author.

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?

Usage is only implied: an agent can infer this is for schema/introspection rather than reading records, but there is no explicit when-to-use, when-not-to-use, or reference to alternatives like get_author. No prerequisites or conditions are stated.

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