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

readOnlyHint=true already tells the agent this is a safe read. The description adds value by disclosing the returned payload shape (role, teams, ticket counts, recent tickets), which matters because no output schema exists, but it says nothing about auth requirements, error behavior, or pagination.

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 compact fragments with no filler. It front-loads the resource payload and appends the endpoint, though the leading noun phrase is a sentence fragment rather than a verb-led 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?

For a two-parameter read with full schema coverage and read-only annotations, the description is adequate but thin: no output schema exists, yet the return content is only sketched, and there is no guidance on usage or selection among the many sibling get_* tools.

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%, including where user_id comes from and what max_tickets controls, so the schema carries the parameter burden. The description only loosely alludes to max_tickets via 'a few of their recent tickets' and adds no format or constraint detail.

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 resource and its payload — 'One user or customer with role, teams, ticket counts and a few of their recent tickets' — which tells the agent exactly what is fetched, and 'GET /users/{id}' anchors it to a single-resource read. It does not explicitly name list_users as the sibling alternative, but the singular framing makes the distinction inferable.

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?

There is no when-to-use guidance, no statement of prerequisites, and no mention of the alternative list_users for bulk retrieval. The only routing hint ('from supportbee_list_users') lives in the input schema, not the description.

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