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

Annotations already declare readOnly/non-destructive/openWorld=false, so the safety profile is covered. The description goes beyond them by disclosing sort order (by name), the privacy guarantee that email addresses are never returned, and an important untrusted-data warning about following embedded instructions.

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?

It is front-loaded with the core purpose, then adds identity/field details and a safety warning. Every sentence carries useful information, though the untrusted-data sentence is somewhat boilerplate.

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 describing returned fields (id, name, role) and the absence of emails. Combined with annotations covering the safety profile, an agent has everything needed to call this correctly.

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 all documented in the schema. The description adds no syntax or format detail for these parameters; its mention of 'id'/'project role' describes output rather than inputs. Baseline 3 applies.

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?

The description states a specific verb and resource ('List the members of one Ybug project'), scopes it to a single project, and clarifies the members are those feedback can be assigned to. It immediately distinguishes itself from sibling list_* tools by naming the assignee role and member identity.

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?

It explains the downstream use of the returned id (for update_feedback's 'assignee' argument and list_feedback's 'assignees' filter), which tells the agent why and when to call it. It does not, however, give explicit when-not-to-use conditions or contrast with an alternative member-listing tool.

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