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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds value by enumerating what the profile contains (activity, location, rate, booking URL), but says nothing about auth needs, error behavior for bad handles, or response format.

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 parenthetical sourcing hint and the field list both earn their place by adding information not present elsewhere.

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?

For a simple one-parameter read tool with no output schema, the description covers the resource, the input's provenance, and the salient returned fields, and annotations cover safety. Only minor gaps remain around handle format and error cases.

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 coverage is 0% and the schema only labels the field "slug", so the description must carry the meaning. It does add real value by equating the slug with a "handle" and naming its source (search_creators), but gives no format or validation hints beyond the schema's length bounds.

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 resource (a single creator profile) and differentiates it from the sibling search_creators by noting it operates on one handle sourced from that search. The verb is only implicit ("A creator profile by handle"), but the scope is unambiguous.

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 parenthetical "(from search_creators)" implies this is a follow-up call after a search, which is useful routing context. However, it never states when not to use it or what to do if the handle is unknown/missing, leaving usage implicit.

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