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

Annotations already declare this as a read-only, idempotent, non-destructive, closed-world operation. The description adds useful context that only approved creators are covered and that the result is a public portfolio containing bio, links, and published content, but it does not describe lookup failure behavior or other operational details.

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, front-loaded sentence with no wasted wording. It efficiently conveys the resource, access scope, and returned components.

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?

An output schema exists, so the description need not enumerate return fields, and annotations cover safety semantics. Still, for a required slug-based lookup, the description leaves the parameter meaning and the relationship to search_creators underexplained.

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 input schema has 0% description coverage for the single required slug parameter, and its only constraint is maxLength. The description implies that a creator can be identified, likely via slug, but does not explain what a slug is, its format, case sensitivity, or whether it refers to an approved creator identifier.

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 states a specific resource and scope: a public portfolio for an approved creator containing bio, links, and published content. It is clear what the tool returns, though it does not explicitly distinguish the read-by-slug behavior from the sibling search_creators tool.

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 phrase 'approved creator' implies this tool is for fetching an existing approved creator's profile rather than searching for creators. However, there is no explicit guidance on when to use this instead of search_creators or what happens for unapproved or unknown creators.

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