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

The description adds useful behavioral context beyond annotations: payroll, home addresses, and emergency contacts are omitted, and access depends on the Shop Boss API key. It confirms the read-only nature already declared by annotations without contradicting them, though it does not cover pagination or response shape.

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 three short, front-loaded sentences with no wasted prose. The return fields, omitted data, read-only behavior, and permission caveat each add distinct value.

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 read-only list tool with no output schema, the description usefully states which employee fields are returned and which sensitive fields are omitted. However, it does not explain the six input parameters, especially pagination and name/ID filters, which leaves a meaningful gap for correct invocation.

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 only 17%, with six parameters and only shopId documented in the schema. The description does not explain page, pageSize, firstName, lastName, or employeeId, so it does not compensate for the low schema coverage.

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 names a specific verb and resource: looking up employee names, job descriptions, mechanic numbers, and active status. It clearly distinguishes this from sibling list tools by naming employee-specific fields, though it does not explicitly frame the operation as a paginated directory listing.

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 by the purpose and by the note that it is read-only, but there is no explicit guidance on when to use this versus related queries. No alternatives are named, and filtering behavior for firstName, lastName, or employeeId is not discussed.

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