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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds real value beyond them: sorted-by-name ordering, email addresses are never returned, and an explicit untrusted-data / prompt-injection warning. It does not discuss pagination behavior, which keeps it at 4.

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?

Three short sentences, front-loaded with the action and scope, then the output semantics, then the untrusted-data caveat. Nothing is redundant with the name or schema.

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 no output schema, the description compensates by naming the returned fields (id, name, role) and the email omission, and it flags untrusted content. An agent has everything needed to call and interpret this read-only listing tool.

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, query, page_size and project_id are already documented, establishing a baseline of 3. The description adds semantic meaning for the member id (its role as assignee/filter value elsewhere) but nothing further about this tool's own parameters.

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 members of one Ybug project") plus scope (members feedback can be assigned to, sorted by name). It also describes the returned shape (id, name, role), which separates it clearly from list_projects and list_feedback.

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?

Explicitly routes the agent: the returned "id" is what update_feedback's assignee argument and list_feedback's assignees filter accept, telling the agent when to call this first. No explicit when-not condition or exclusions, so it falls short of a 5.

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