get_employee_details

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

With no annotations, the description carries the burden of behavioral disclosure. It states that the tool returns employee ID and manager ID, which is useful, but it does not disclose behavior for edge cases (e.g., name not found, multiple matches) or confirm that the operation has no side effects. The verb 'Get' implies read-only, but this is not explicitly stated.

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 extremely concise, using a single line for the purpose and a clean :param/:return format. Every sentence adds value with no wasted words or repetition of the tool name or schema fields. The structure is easy to scan and understand.

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 simple tool with one parameter and no annotations, the description covers the core purpose and return values. The presence of an output schema reduces the need to explain return structures in detail. However, it lacks explicit handling of ambiguous name matches or 'not found' behavior, which could be relevant. Overall, it is adequate for basic use but not exhaustive.

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?

The schema has 0% coverage, so the description must compensate. It explains the 'name' parameter as 'Name of the employee' and specifies the return values, adding meaning beyond the bare schema. It does not detail format or uniqueness constraints, but it provides enough for basic usage. This partially compensates for the lack of schema-level 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 a specific action ('Get employee details') with a defined lookup method ('by name'), and the resource is distinct from all sibling tools (leave, tickets, meetings). It uses a clear verb+resource structure that eliminates ambiguity about what the tool does.

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 usage when employee details are needed, but it does not explicitly state when to use this tool over alternatives or provide exclusions. There is no mention of cases like when the employee name is ambiguous or when to prefer a different lookup tool. Context is implied rather than explicitly stated.

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