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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, and the description's 'Read only' merely restates that. The only added information is the owner scoping; nothing is said about ordering, pagination, result count, or what a 'creator search' record contains.

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?

Two short sentences with the purpose front-loaded and no filler prose. The second sentence ('Read only') is redundant with the annotations and spends words without adding information, which keeps it off a 5.

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 no-parameter list tool with no output schema, the description is minimally sufficient to call it. It does not explain what a 'creator search' is or what the listing returns, which matters here because there is no output schema to describe the payload.

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 schema carries the entire input burden and there is nothing for the description to clarify. Baseline 4 applies for a parameterless tool.

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 and resource ('List the owner's creator searches'), which is unambiguous on its own. However, it never distinguishes itself from the closely named siblings soclo_creators_search, soclo_creators_search_results, or soclo_creators_shortlist, so an agent must guess how this listing differs from retrieving search results.

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: the 'owner's' qualifier suggests it returns previously created searches, and 'Read only' hints it is the non-mutating counterpart to soclo_creators_search. There is no explicit when-to-use, when-not, or named alternative, so routing between the three creator-search siblings is left to inference.

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