add_employee

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

With no annotations, the description carries the full burden of behavioral disclosure. It only mentions adding an employee and returning a confirmation, but omits details about side effects, validation, error handling, or permissions. Additionally, it lists manager_id as optional while the schema requires it, creating internal inconsistency.

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 action, but the parameter list is incomplete and contains an error, meaning not every sentence earns its place. A tighter, accurate enumeration of params would be better.

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?

Although the tool is simple, the description fails to mention one required parameter (email) and misstates another (manager_id). For an agent to invoke the tool correctly, it must know all required fields and any constraints, which are not provided here.

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 explain each parameter. It covers emp_name and manager_id but omits email entirely, and incorrectly labels manager_id as optional despite being required in the schema. This provides incomplete and misleading information to the agent.

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') and the system ('HRMS'), matching the tool name. It is distinct from sibling tools like get_employee_details, which retrieve data, and send_email, which handles communications.

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?

No guidance is provided on when to use this tool instead of alternatives, nor any prerequisites such as whether an employee must already exist or whether email uniqueness is enforced. The description only states what it does, not the context or exclusions.

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