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 'Read-only' clause mostly restates structured data. The genuinely additive detail is that results are limited to published, featured, Core-managed profiles — a real scoping trait — but nothing is said about ordering, pagination, or what an empty directory means. Comparable to the calibration case where scope context without return detail earned a 3.

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 resource and its scope front-loaded; nothing is buried. The trailing 'like every other tool' adds little and partly duplicates what the annotations already establish.

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, non-destructive read tool with no output schema is adequately covered: the description says what entity set is returned and under what publication conditions. Only minor gaps remain around result shape and ordering, which are low-risk for a directory read.

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 baseline of 4 applies and there is no parameter semantics burden for the description to carry.

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 ('Get the ... team member directory') and narrows scope with 'published, featured' and 'Core-managed People profiles', which distinguishes it from the single-person get_person_profile sibling. It stops short of naming any sibling explicitly, so differentiation is inferred from the resource noun rather than stated.

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 'Read-only and published-only' implies when the tool applies and excludes unpublished content, but there is no explicit when-to-use statement and no named alternative (e.g. get_person_profile for an individual, search_content for discovery). The agent must infer the routing.

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