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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds the returned field set and the underlying endpoint, but says nothing about error behavior when no employee matches or how ambiguities are resolved.

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?

Two sentences, front-loaded with what is returned and followed by the identifier rule and endpoint. No filler, and the constraint an agent is most likely to violate is stated plainly.

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?

With no output schema, the description compensates by enumerating the returned fields, which is the right call. It is only slightly short on edge-case behavior (missing employee, permission scope) for a straightforward read tool.

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 coverage is 100%, so the three identifier parameters are already documented individually. The description adds a constraint the schema does not express: exactly one of user_id, employee_id or email must be supplied, which is meaningful since required is empty in the schema.

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 ('Get') and resource ('employment info') for exactly one employee, and enumerates the returned fields (branch, class, grade, job, contract/probation dates, approval line). It does not explicitly differentiate itself from the sibling talenta_get_employee, so an agent must infer the split from the field list.

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 is implied: fetch a single employee's employment record by one identifier. The description never names alternatives such as talenta_get_employee or talenta_list_employees, nor does it say when to prefer this over them. The lookup-identifier rule it does give is parameter guidance rather than tool-selection guidance.

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