get_employee_details_by_employeeId

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

No annotations are provided, so the description carries the full burden. It does not disclose any behavioral traits such as whether it is read-only, side effects, authentication requirements, or error handling. For a get operation, it implies read-only but does not state it, and no output schema is provided, leaving behavior largely opaque.

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 short (5 words), which could be considered concise, but it under-specifies rather than being efficiently informative. It is front-loaded with the purpose, but the brevity results in missing critical information, making it insufficient.

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?

The tool has one parameter, no output schema, and no annotations. Given this, the description should at least indicate what 'employee details' entails (e.g., which fields are returned) and any special cases. It does not, so it is incomplete for practical use.

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%: the parameter employeeId has no description in the schema. The tool description repeats 'by employeeId' but adds no additional meaning. Given low coverage, the description should compensate but does not clarify format (e.g., UUID, string) or any constraints.

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 states it retrieves employee details by employeeId, which is a clear verb+resource+identifier. However, it lacks differentiation from sibling tools (e.g., get_leave_balance, apply_leave) which are about leave, not employee details, so there is some implicit distinction. It is not a tautology but is minimal.

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 usage guidelines are provided. The description does not specify when to use this tool versus alternatives, but since it is the only employee details tool among leave-focused siblings, the usage context is somewhat implied. Still, no explicit guidance for when-not-to-use or prerequisites.

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