list_tickets

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

No annotations are provided, so the description carries full burden. It discloses that the tool returns a list of tickets, but does not mention behavior for missing employee, pagination, ordering, or error handling. Additionally, the description contradicts the schema by stating status is optional when schema requires it, reducing trustworthiness.

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?

The description is short and to the point, with no filler. However, it uses a Python docstring format with :param and :return lines, which is slightly verbose for an MCP description but still clear and front-loaded.

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?

Given the low complexity (2 parameters, no nested objects), the description is minimally adequate. It mentions the return type (list of tickets) but does not cover edge cases like no matching tickets. An output schema exists, so return format is documented elsewhere, but behavioral gaps remain.

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 coverage is 0%, so the description must compensate. It adds meaning: employee_id is the employee ID, status is ticket status and optional. However, the contradiction about status being optional undermines clarity. Overall, it provides some value beyond the empty schema descriptions.

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 clearly states the verb 'List' and the resource 'tickets for an employee', with an optional status filter. It distinguishes from sibling tools like create_ticket and update_ticket_status, but does not explicitly differentiate from other list tools.

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 implies using the tool to list tickets for a specific employee, with an optional filter by status. However, it lacks explicit guidance on when to use this tool versus alternatives, or any prerequisites or exclusions.

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