get_employee_details

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

No annotations are provided, so the description must fully disclose behavioral traits. It only says 'Get employee details by name' with no information about return format, error handling, permissions, or side effects. The read-only nature is only implied by the tool name, 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 a single, concise sentence with no wasted words, but it is under-specified. It essentially restates the tool name and parameter without adding useful structure or detail, which is closer to under-specification than effective conciseness.

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 getter with one parameter and an output schema, the description covers the basic necessity, but lacks any guidance on edge cases like employee not found or name matching behavior. The existence of an output schema mitigates the need to explain return values, but more context would improve completeness.

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 one required parameter 'name' with type string and no description (0% coverage). The description adds that the lookup is 'by name', clarifying the parameter's role as the search key. However, it does not specify format, exactness, or case sensitivity, so the added meaning is minimal.

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 'Get employee details by name' clearly identifies the action (get), resource (employee details), and lookup method (by name). It distinguishes itself from sibling tools like add_employee or get_leave_balance, which operate on different resources or purposes.

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?

Usage context is only implied: use when you need employee details and have a name. There are no explicit when-to-use or when-not-to-use instructions, nor mention of alternative tools, making this a minimal viable but not highly guided description.

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