get_employee_details

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions return fields (Employee ID and manager ID), but an output schema already exists, and it omits auth requirements, error behavior, handling of duplicate names, and explicit confirmation that the operation is read-only.

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 front-loads the main purpose, but the param and return lines are largely redundant given the input schema and output schema. The leading newline and docstring-style formatting are also not ideal for a tool description.

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 one-parameter read tool with an output schema, the description covers the basic purpose and return fields. However, it lacks prerequisites, error behavior, and safety context, making it only minimally adequate.

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 0% for the single parameter. The description adds only ':param name: Name of the employee', which essentially restates the parameter name and title without specifying format, case sensitivity, or how to disambiguate duplicate names.

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 ('Get employee details') with a scope ('by name'), so the agent knows exactly what the tool does. It does not explicitly distinguish from siblings like add_employee or get_employee_leave_balance, but the resource scope is clear enough.

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 provides no when-to-use guidance, no alternatives, and no exclusions. Usage is only implied by the tool name and 'by name' phrase.

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