add_employee

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

With no annotations provided, the description carries the full burden. It does mention a confirmation message as the return value, but it fails to disclose side effects, permissions, or validation behavior. More critically, it contradicts the input schema by labeling manager_id as optional when the schema requires it, which is misleading.

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 concise and front-loaded with the core action. The :param/:return format is somewhat archaic but not verbose. However, structure is hampered by missing email documentation and the optionality error, which reduce overall clarity.

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 create operation, the description provides a basic purpose and return value, but it is incomplete: it omits the email parameter, contradicts the schema on manager_id, and offers no context about validity, permissions, or when to use the tool. The output schema exists but is not referenced or explained.

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%, so the description must compensate. It offers brief semantics for emp_name and manager_id, but incorrectly marks manager_id as optional and omits the email parameter entirely. This partial and inaccurate coverage does not reliably aid the agent in understanding required inputs.

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 action 'Add a new employee to the HRMS system,' which is specific and identifies the resource. However, it does not explicitly differentiate from sibling tools like get_employee_details or apply_leave, and the optionality of manager_id introduces ambiguity about actual inputs.

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 guidance on when to use this tool vs. alternatives. The description lacks any context about prerequisites, appropriate scenarios, or when other employee-related tools should be used instead.

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