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

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint=false, so the safety profile is fully covered without the description. The description adds nothing behavioral beyond that: no pagination semantics, no note that search/platform_id narrow results, no indication of result ordering or size.

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 short sentence with the resource scoping front-loaded and no filler. It is appropriately sized, though its brevity borders on under-specification rather than disciplined conciseness.

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?

With 100% schema coverage and complete annotations, an agent can call this correctly, so nothing critical is missing. But with no output schema and no description of return shape, ordering, or pagination behavior, the definition is only minimally complete for a list endpoint.

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 description coverage is 100%, so page, search, per_page, and platform_id are each documented in the schema (including the Discord snowflake lookup). The description adds no parameter meaning of its own, which is the baseline 3 when the schema carries the full burden.

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 (List) and resource (this community's members), so the core operation is unambiguous. However, it offers no differentiation from near-siblings like get_member (singular) or list_interviewers, so the agent must infer the boundary from the name alone.

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 description gives no when-to-use guidance, no mention of filtering options, and no pointer to alternatives such as get_member for a single member. The only implied guidance comes from the verb 'list' versus 'get', which the agent must supply itself.

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