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

Annotations already declare readOnlyHint, destructiveHint=false, and closed-world, so the safety profile is covered and the description only needs to add context. It adds the trigger timing and hints that the output enumerates options plus their requirements, but says nothing about format, completeness, or whether calling it has side effects. Adequate but thin beyond the annotations.

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 no filler, and the purpose is front-loaded ahead of the call trigger. Only 'what each option needs' is imprecise wording that slightly weakens an otherwise tight statement.

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?

A zero-parameter, read-only discovery tool with no output schema is a low-complexity case, and the description covers purpose and call timing. Given a 16-tool sibling set, it could do a bit more to frame itself as the entry point that routes to the scoring/vetting tools, which is the only remaining gap.

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 there is no parameter semantics to explain and the baseline applies. Nothing in the description misdescribes the input contract.

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?

Specific verb+resource: it shows CreatorScore's capabilities and the requirements for each option. It is clearly distinct from the sibling tools, which are all concrete scoring/vetting operations rather than capability discovery. The phrase 'what each option needs' is slightly vague about whether it means prerequisites or parameters, keeping it from a 5.

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?

Gives explicit triggers: on user connection and when the user asks what the agent can do. That is clear usage context with no exclusions, but it does not say when to avoid this tool or how to route from here to a specific sibling.

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