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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds genuine behavioral context beyond that: four sensitive field families (national id, passport, bank account, health) are redacted by default and only returned when include_sensitive is true — material to an agent assembling an employee profile.

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, zero filler, with the payload contents front-loaded and the redaction caveat immediately after. Nothing repeats the title or wastes a clause.

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 correctly takes on the burden of describing what comes back by listing the field groups, and it covers the sensitive-data switch. It leaves out error/not-found behavior and whether the id accepts a non-numeric Talenox identifier, which are the remaining gaps.

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%, and the schema already spells out that id is the numeric id from talenox_list_employees and that include_sensitive defaults to false. The description restates the sensitive-field list without adding format, validation, or edge-case detail, so the baseline 3 applies.

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 and resource ('Get one employee's full record') and enumerates the record's contents (personal details, jobs, cost centres, custom fields). The singular 'one employee' implicitly separates it from talenox_list_employees, but no sibling is named explicitly.

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 only implied: the tool is clearly for fetching a single employee, and the include_sensitive clause hints at when to widen the payload. There is no explicit guidance on when to prefer talenox_list_employees, what to do if the id is unknown, or how to handle a missing record.

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